So what’s the deal with VOCs?

[Article from the January 2013 issue of Architect & Specificator]

VOCs Explained

Should I paint first or tile first? I want to avoid getting any paint on new tiles and grouting.

When deciding to tile first or paint first, this will depend on personal preference. Our advice would be to tile first and allow the tile cement and grouting to completely cure. Then cover the tiles with drop-sheets and masking tape before painting. It would be much easier to cover a floor when painting than to cover walls while doing the tile work.

< back to the top

Can I paint over melamine cupboards?

You certainly can! Here’s what you need to do.

1. Remove any oil and greasiness with a Polycell Sugar Soap Powder solution and scouring pad. For firmly adherent cooking oils in kitchen areas, use Aquasolv Degreaser. Rinse thoroughly with water and allow to dry. Once dry lightly sand the surface then dust off.

2. Apply 1 coat of Plascon Tile & Melamine Primer and allow to dry. Once dry, apply 2 coats of Plascon Kitchen & Bathrooms paint. Please find the data sheets for these products attached in the link provided.

How do you get mould out a bathroom ceiling?

  • The ceiling should be scrubbed using a 3.5 % Sodium Hypochlorite Solution (house hold bleach – JIK) mixed 2 parts water to 1 part bleach.
  • This is left on the surface for 30 minutes then washed off with a sugar soap solution.
  • If this was a previous enamel surface it should be sanded to a matt finish and dusted off.
  • One coat of Plascon Universal Undercoat (UC1) must be applied and left to dry for 16 hours.
  • Then apply two coats Plascon Kitchens and Bathrooms over the Plascon Universal Undercoat (UC1) or directly to previous acrylic finishes. This will prevent fungal growth.
  • NB: A window should be left open to provide good ventilation after showering.
  • Remember to always wear gloves and safety glasses when handling volatile substances.

How do I get PVA Paint off a raw pine cupboard?

Woodcare Coating Remover For Wood is what you need!

We recommend conducting a small test patch in an inconspicuous area to ensure product performance. This will also indicate the time required for project completion, suitability of product for paint and substrate, and the most effective removal method.

< back to the top

Can I use Plascon Nuroof to paint a slate tile roof? The roof sheets are 60 x 40 and a fibrous looking grey.

Plascon does not recommend the painting of slate roof tiles at all. The slate roof tiles are non-porous so no adhesion will take place. It will be done at own risk and there will be no guarantee.

< back to the top

What is the best way to get paint off a door handle?

  • If the paint is relatively fresh, rub off using a mutton cloth soaked in lacquer thinners.
  • If it is old, use Plascon Removall All Purpose Paint Remover (RRA 220).
  • Apply a heavy coat over the paint and allow 2 hours to react, then scrape and wash off with water.

< back to the top

Where can I download Plascon Colour Cards from?

Please note that we do not supply any colour cards online as digital renderings of our colours are not accurate. You may get hold of the colour cards from any retail store that stocks our products. Or you may contact our colour consultants on 011 467 8693 to inquire if they have soft copies of the colour cards you require.

How do I go about whitewashing my child’s bunk-bed?

Here’s what you need to do:

  1. Use paint stripper and a scraper to remove the varnish from the wood – pour hot water over the stripper to remove stubborn bits.
  2. Degrease with sugar soap and allow to dry.
  3. If you want the wood grain to show through, mix 50% Plascon White Cashmere and 50% Plascon acrylic scrumble together in a bucket.
  4. Apply a generous layer of the paint mix onto the wood and let it dry for a day. The acrylic scrumble is a paint retarder and requires 12 hours drying time. (REMEMBER: The more layers you use of this paint mix the lighter the wood becomes)
  5. Seal with a Plascon water-based sealer: apply two coats and let it dry after each application.

How do you strip enamel paint off ceilings and cornices?

If your ceiling is rhino board then you need to sand the ceiling to a firm edge because you cannot use any of our Removall products as they are water-based and rhino board is sensitive to water. If your ceiling is knotty pine then you can use our Woodcare Coating Remover for Wood.

< back to the top

What type of Plascon paint should one use to paint glass?

We unfortunately do not make paint that can adhere to glass, but can advise that you contact Duram on 0800 500 222 as they manufacture glass paint.

How do I give my pine table a weathered vintage French look?

To create this effect on pine, sand and prime then paint your table in a dark brown shade (I suggest Plascon Double Velvet). Let the paint dry then rub a candle on all the edges and detail areas to retain the colour. Now give the table 2-3 coats in an off-white/sandy colour (I recommend a super acrylic paint like Plascon Polvin). Let each coat dry thoroughly before applying the next. Then create the magic by sanding lightly (or use a scraper) on all the waxed areas (the off-what/sandy-coloured paint wouldn’t have adhered to these). This will create a lovely distressed look.

You can also apply an antiquing liquid over the entire table and then seal it with a few coats of a water-based varnish, such as Plascon Woodcare Water-based Varnish for interiors. Alternatively, apply this technique to the legs and the base of the table, then stain the top darker.

< back to the top

How should I go about painting the legs of my pine table white?

If the varnish is in good condition (and you wish to paint the legs a flat white rather than a whitewash – in which case you would have to remove the varnish entirely) you can lightly sand the legs with 220-grit sandpaper, wash them down with a sugar soap solution and then apply a primer (Plascon Multi Surface Primer) followed by an acrylic PVA or water-based enamel. Sand lightly between coats.

Do you have a product that I can use to paint a concrete driveway?

Yes! Here’s what you need to do:

Ensure that the surface is clean, sound and dry. Clean the floor with Plascon Aquasolv Degreaser (GR 1) and rinse thoroughly with clean water. Allow to dry for at least 48 hours until totally dry.

For all smooth surfaces, particularly steel floated concrete, apply one coat of Plascon Concrete Floor Prep (FCS 1). Allow the surface to dry for 8 hours before applying Plascon Floor Paint (FPT Range). Please find attached technical data sheet and refer to surface preparation, applications and cautions.

What paint can you use on floor tiles in a kitchen, and in a bathroom?

We do not recommend that the floor tiles be painted with DIY products.

< back to the top

What paint is best for a child’s room that is water-based and lead-free?

All our decorative products are lead-free. Depending on the required finish we have two water-based products that are perfectly safe to use for children’s rooms.

One can choose between Plascon Double Velvet, which has a velvet sheen finish, and Plascon Cashmere, that has a plush matt finish. Both of these products are washable and stain resistant.

< back to the top

Can I dilute thickened Plascon Universal Undercoat with mineral turps?

Plascon Universal Undercoat (UC1) can be thinned with maximum 10% of Mineral Turpentine (AZH1).

< back to the top

Please can you advise me on the best way of treating rising damp on walls?

Rising damp can arise for various reasons – the failure of an existing DPC, bridging due to the raising of external ground or internal floor levels, or in older buildings, the complete absence of a DPC.

I suggest the following remedial specification:

  • Remove all loose and flaking paint by scraping.
  • Where bare cement may be encountered only, apply 1 coat of Plascon Plaster Primer (UC 56) and allow to dry for at least 16 hours.
  • Apply 2 liberal coats of Plascon Dampseal by brush.
  • Allow for at least 4 hrs to dry between coats.
  • As a finishing apply 2 coats of Plascon Micatex (BBO300).
  • Allow at least 1 hour drying time between the final top coats.

< back to the top

How do you get dried paint off glass windows without scratching the glass?

You can remove water-based coatings with a plastic scraper and Methelated Spirits. For solvent-based coatings try Polycell Brush cleaner and a plastic scraper.

Please keep in mind that one should work carefully without spilling the Spirits or Brush Cleaner onto the surrounding walls as this will soften the paint.

You can also use Plascon Removeall as long as you make 100% sure none of the Removall gets onto the surrounding painted areas as it will remove the coatings if spilled.

Do you have a similar product to Polycell SmoothOver here in South Africa?

According to the description of Polycell SmoothOver it might be the equivalent of our Terraco Handycoat Ez Skim (TER1200). TER1200 bonds extremely well to cementitious materials, gypsum, building boards, spray plasters, wood, galvanised steel lathings and all common building surfaces.

It can be used as a full skimcoat, for patching hairline cracks in walls, ceilings, repairing damage to plaster or paint work, nail holes in woodwork, making good around door architrave’s and along the top of skirting boards. The only difference we can find is that Polycell SmoothOver can be used on floors while our product should not be used on floors.

What is the best way to go about painting a precast wall that has black algae on it?

Scrub the affected area using a solution of household bleach – mixed 1 part bleach to 2 parts water. After 1 hour or marked colour change (lighter), brush clean using a hard bristle brush. Then rinse thoroughly with fresh water to remove all traces of bleach and allow to dry.

Ensure that surface is dry, sound and clean. Prime with one coat Plascon Plaster Primer with an overcoating time of 16 hours and finish with two coats Wall & All with 2 hours drying time between coats.

< back to the top

How should I care for my brush so that it maintains its performance level use after use?

Clean immediately after use, with:

  • Plascon Brush Cleaner, mineral turpentine or paint thinner if you have painted with solvent based paints (Enamel, varnish, oil)
  • Soap and water if you have painted with water based paints (Latex, Acrylic, PVA)
  • Use a comb to clean and straighten the bristles.

Do not soak your brushes for extended periods of time. They will lose their shape if you do. If possible, store your brush by hanging it. Do not store a brush on its tips. This will curl the working tip of the brush rendering if useless.

< back to the top

What do you do if you have painted PVA on top of enamel and the pva scrapes off easily?

  • Scrape as much PVA off the surface as possible as the there will always be poor intercoat adhesion.
  • Strip the “stubborn areas” using the Plascon Removall All Purpose Paint Remover (RRA 220) apply to “stubborn PVA surfaces” and allow to react for 1 hour before scrapping the paint off.
  • Wash thoroughly with Sugar Soap Solution and rinse with tap water.
  • Sand to a matt finish. Dust off.
  • Apply 1 coat of Plascon Universal Undercoat (UC1) and allow 16 hours to dry.
  • Acrylic top coats may now be applied such as Plascon Double Velvet, Cashmere or Wall& All.

What can I use to paint varnished pine furniture? How should the furniture then be prepared?

For previously varnished wood (in poor condition): Remove old paint/varnish with Woodcare Coating Remover for Wood or by scraping and sanding. Sand wood in the direction of the grain to a smooth finish. Dust off and apply Plascon Wood Primer allowing 16 hours drying time. Finish with two coats of Plascon water-based Velvaglo – a premium quality satin finish non-drip water-based enamel for interior and exterior application. Used as a decorative and protective finish on interior and exterior primed woodwork, cement plaster, concrete or metal surfaces, ideal for furniture, doors and wall surfaces.

For previously varnished wood (in good condition): Sand the varnish back to a matt finish and dust off. Should you sand back to bare wood, you will need to first prime bare areas with Plascon Wood Primer then apply one coat of Plascon Universal Undercoat and allow it to dry for 16 hours. Finish with two coats of Plascon water-based Velvaglo a premium quality satin finish non-drip water-based enamel for interior and exterior application. Used as a decorative and protective finish on interior and exterior primed woodwork, cement plaster, concrete or metal surfaces – ideal for furniture, doors and wall surfaces. Ensure that the varnish is sanded to a matt finish.

When painting tiles do you paint over the grouting and will it still look like a tiled surface afterwards?

Yes, you do paint over the grouting and the tiles will still be visible. Alternatively, remove the tiles, skim over rough areas, prime and paint.

Can Plascon’s Metalcare Rust Converter & Primer be used on cast iron? Can it be used on sheet metal?

Metalcare Rust Converter & Primer is intended for use on rusted mild steel. It should not be used on cast iron and can only be used on sheet metal if the metal is Mild Steel. Please see the Technical Datasheet for more info.

< back to the top

What kind of paint should you use over rough and uneven plaster work, if you can’t have the walls re-skimmed?

Textured coating should be used to mask uneven plaster work. Depending on the unevenness the following suggestions can be used:

  1. Very uneven surfaces – Plascon Marocca – stippled rolled using a yellow sponge roller.
  2. Medium Plaster defects – Plascon Pollycel Ripple applied by a yellow sponge roller providing a round ripple finish.
  3. Limited plaster imperfections – Plascon Micatex applied by a yellow sponge roller creating a fine texture.

All the above coatings may be over-coated with the original acrylic coating used on the building.

Can Plascon tester pots be mixed in any colour and how much do they retail for? Also, what is a tint-base exactly?

Plascon tester pots can be mixed in most of the Inspired fan-deck colours, except ultra pastel (where the colorant shots are too small) and retail for R29.99.

A tint-base is a factory manufactured base (pastel, deep & transparent) and contains no colorant. The colorant is then added in-store to a calculated formula in order to achieve a specific colour as depicted in our Inspired colour fan-deck.

Please see our Tester Pots page for more info on where they are available.

I want to paint my kitchen cupboards, which are oak. I would like to know if I need a primer if I will be using Velvago?

For oak kitchen cupboards you will first need to make sure that the surface is clean, dry and sound. If the cupboard has never been painted before, you will need to apply one coat of pink wood primer (UC2) and allow this to dry for 16 hours at 23º. You can then overcoat this with two coats of Velvaglo with 16 hours drying time between coats.

How do you paint cupboard doors to get that “spray” or “ducco” finish but using enamel paint at home and if you don’t have a spray gun?

  • Sand to a smooth finish using 220 grit paper, dust off.
  • Plascon Velvoglo would be the better product to use because it is self leveling and produces a semi-matt finish for aesthetics.
  • However the mode of application to obtain a spray finish is by using a fine sponge roller for both Plascon Velvaglo and Plascon Enamel Doors & Trims.
  • This should be “cross-rolled” then layered-off in downward strokes. (A mohair roller can also be used but it not a smooth a sponge roller)

If you have an outside “stoep” that is painted in stoep enamel, but is very slippery when wet, is there anything you can do?

In order to eliminate the slippery finish on stoep paint, add 100grams of Plascon Grip Additive (PGA 1) to 5lts of Plascon Stoep Paint and apply same over previously prepared stoep paint surfaces. Up to a 150grams can be added for additional slip resistance.

How do you fix up an outside wooden gate, where the clear wooden varnish has started to peel off and go yellow and brittle?

  • Apply Plascon Removall Coating Remover for Wood (RWI 220) applied thickly over the old varnish.
  • Allow to react for 2 hours then scrape off. Repeat on “Stubborn Areas” until varnish is removed.
  • Then apply Plascon Removall Simple Wash ( RWS 80) to entire area.
  • Allow to react for 30 minutes then rinse off with water and allow to dry.
  • Sand the timber to a smooth finish removing all raised timber grain with 220 grit paper and dust off.
  • Apply 3 coats of Plascon Woodcare Sunproof (PNW) to the wooden surfaces – thinning the first coat 10% with mineral turps.
  • Allow 16 hours drying between coats. Lightly sand (between coats) with 220 grit paper to de-nib any raised timber grain.

What is the easiest way to keep walls clean in high traffic areas, where they are constantly getting dirty from finger marks and handprints?

  • Clean the surface with a Sugar Soap Solution and rinse with tap water. Stubborn marks should be re-coated with similar acrylic and colour previously used.
  • Then apply 2 coats of Plascon Glazecoat Ref 1124 Gloss or Ref 1125 Matt – allowing 2 hours drying between coats.
  • In future the dirty marks will then be easily cleaned with a mild sugar soap solution.

We have had new claddit ceilings fitted to our house. At present they are new and bare. How would you suggest we go about painting?

In days gone by, claddit was the term used for “asbestos” ceiling boards. The new term for these ceiling boards is “fibre cement boards” as they do not contain asbestos anymore. Before painting, it is important to first determine the exact substrate of ceilings as there are many different types of cladding on the market today e.g. Cork, Polystyrene etc.

  • Then apply Plascon Removall Simple Wash (RWS 80) to entire area. Allow to react for 30 minutes then rinse off with water and allow to dry.
  • Sand the timber to a smooth finish removing all raised timber grain with 220 grit paper and dust off.
  • Apply 3 coats of Plascon Woodcare Ultravarnish (X33/44) to the wooden surfaces, thinning the first coat 10% with mineral turps.
  • Allow 16 hours drying between coats. Lightly sand (between coats) with 220 grit paper to de-nib any raised timber grain.

I just bought a house and the previous owner painted the whole house inside with enamel. Do I need to scrape it down or can I just put universal paint over it and repaint?

Here’s what you need to do:

1. Ensure the surface is clean, sound and dry
2. Sand lightly to create a key and dust off
3. Apply one coat of Plascon Universal Undercoat allowing 16 hours drying time
4. Finish with two coats of your chosen water-based topcoat

Can bonding liquid be used on exterior walls that are still painted or must it only be used on plastered surfaces?

Bonding liquid can be used on a painted surface if the paint is in poor condition. Sand the surface slightly, wash with sugar soap and rinse. Allow to dry before application of bonding liquid. Please note that the inclement weather will retard drying times.

I want to paint my kitchen cabinets so they have that seamless, “sprayed on” enamel finish, but I don’t have a spray gun. How do I achieve this effect?

Unfortunately, nothing replaces that beautiful finish achieved by using a spray gun. Using Aerolak spray canisters is an option, but over-spray in a confined area might be a challenge. If the surface is flat, applying Plascon Velvaglo with a sponge roller always gives a good finish.

I have just moved into an old house, in which the living room has been wallpapered. Can I paint directly over it? I also want to repaint the rest of the house, but don’t know whether the paint is enamel or water-based. Please help!

Congratulations on your new home! Painting wallpaper is generally not recommend due to various factors, such as the age of the wallpaper and the condition of the surface beneath it. However, you can perform a test on a small area to see if the wallpaper won’t lift or bubble. Apply Plascon Multi-Surface primer to the test area and leave to dry overnight. If the wallpaper is still in a good condition, the whole surface can be primed and painted.

I’ve inherited quite an old-fashioned wrought iron patio set from my gran and would like to give it an update. What type of paint can I use on wrought iron? And do I need to remove the old paint first?

Updating old furniture with paint is a great idea. If the coating is adhering well, there is no need to remove it. There will no doubt be chip marks, exposing the cast iron, though. Sand these spots well to ensure feathering of the edges, then spot prime the bare metal with Plascon Metalcare Etch Primer (SNK 200). Next, rub down the entire frame using a Scotch-Brite® pad. Finish off with two coats of Plascon Velvaglo.

How do I keep my paintbrushes and rollers in good condition? Mine always go tatty quite quickly.

After using a roller and water-based paint, wash it and rinse under running water as soon as possible. To fluff the roller, spin it against a flat surface outside. You’ll get wet during this exercise! Next, hang the roller by the handle on the washing line until dry. Cleaning a brush that was used with enamel or water-based paint is a simple exercise. After rinsing with turpentine (in the case of enamel) or water (if it’s water-based paint), pour a little Polycell brush cleaner into a jar and work the bristles well until totally clean. Rinse with water and your brush will be as good as new.

Can you please advise us what to do with our rusted chromodek roof sheets? We need to know after we replace the rusted roof nails with new roof nails, how we can seal it and what kind of paint can we use to paint the roof sheets?

Certainly! Here’s what you need to do:

  1. Clean surface thoroughly with POLYCELL SUGAR SOAP POWDER solution or REMOVALL HIGH STRENGTH CLEANER & DEGREASER (RCI 70). Areas showing red rust must be sanded off back to bright metal.
  2. Rinse thoroughly with clean water to neutralise. Allow to dry and patch prime with PLASCOSAFE 18 PRIMER (EMS 18) only over the replaced nail heads allowing 8 hours drying time.
  3. Next prime the whole surface with EPIWASH STRONTIUM CHROMATE PRIMER (AW 255) allow 4 hours drying time at 23 °C (but not more than 24 hours).
  4. Finally apply NUROOF COOL (TRP 200 Range) before contamination of the surface can take place allow 2 hours drying time between coats.

    • Hi Jilian, thank you for your query.

      Woodcare Coating Remover For Wood is what you need!

      We recommend conducting a small test patch in an inconspicuous area to ensure product performance. This will also indicate the time required for project completion, suitability of product for paint and substrate, and the most effective removal method.

  2. Can stoep paint be thinned with thinners for the first coat? My tenant gave painter thinners to use. I see that you recommend thinning the first coat with turpentine.

    Also he used a high-pressure machine to take off the old paint and filled the cracks with cement. How long after doing this should one wait before painting?

    Thank you.

    • Hi Susan, thank you for getting in touch.

      It is not advised to use thinners to thin down Stoep paint as thinners evaporates too quickly causing the paint to dry before adhesion takes place. We advise that you rather use turpentine or benzene for this purpose.

      If thinners is used you will likely encounter problems. The paint will “curdle” (turn into a gel-like paste) and it will definitely negatively affect the drying time of the product.

      To answer your question regarding the cracks, it will depend if the area is exposed to a lot of sunlight. But on average, for cemented cracks you are looking at 5-10 days drying time before they can be painted. Unless a drying agent was added to the cement, in which case we would suggest a 24hr waiting period.

  3. Hi, I have a pine chest of drawers that I’d like to paint white. How do I go about doing this? It has no varnish/staining/paint on it currently, so can I just start with a primer and paint or do I need to treat the wood and the knots first. I’ve read so many different methods, I’m not sure how to go about it.
    Thanks!

    • Hi Chrissy.

      Thanks for reaching out to us.

      The wood would require a light sand in the direction of the wood grain. Do this using 180 grit cabinet paper. Be careful not to scratch the wood. Wipe off all dust and ensure the surface is free from all oils and contaminants. Apply 1 coat of Knot Seal over the knots in the wood and allow to dry for 1 hour before application of primer. Plascon Wood Primer (oil based) or Multi Surface Primer (waterbased) can be used. Wood Primer feeds and nourishes the wood avoiding splitting and cracking, but takes 16 to 24 hrs to dry. Multi Surface Primer does not feed the wood but takes between 4 to 6 hrs to dry. Once the primer is dry 2 coats of Velvaglo White can be applied with a 16 to 24 hr interval between coats. It has a built in Undercoat. Should you paint a waterbased topcoat on such as Wall & All, I recommend the use of an undercoat over the primer before application of the topcoat.

      All the best!

    • Hi Theo,

      Please could you specify where the galvanized sheet metal will be used as there is a difference in treating it for different applications. Eg: Roofs or side cladding on a building.

  4. My asbestos facia boards on the ends of my house are covered with a black algae. They have been sanded and washed down many times over the years, but the algae always returns after a short time after painting with a PVA (usually Plascon Polvin). They are in bright sunlight. I am now starting over again.

    What is the best I can do?

    • Hi John, thanks for getting in touch.

      Sounds like such a shlep! First and foremost, you will need to contact your local municipality to properly clean the asbestos surface for you.

      Once properly cleaned, you should then prime the bare asbestos with one coat of Plascon Plaster Primer and allow it to dry for 16 hours.

      To ensure the algae doesn’t return, use Plascon Universal Fungicide (REF 502) mixed 100ml in to Plascon Polvin 5L and apply 2 coats with 2 hours drying time in between coats.

  5. Hello Plascon.

    I want to paint a carport roof with Plascon Nuroof. I want a very light color to blend with the walls of the house.

    If I buy 5l white Nuroof and 5l Terracotta Nuroof and mix in say a half cup terracotta into the 5l white, I will probably get the colour I want.

    Question: Will this mess with the chemical make up of the paint? I am not worried about invalidating the guarantee, I just want to know if the resulting paint will be useable and will not fade.

    • Hi Brian, thanks for getting in touch.

      We do not recommend tinting standard colours as there is already pigment in the products – each with different properties. It is very possible that the colour will not come out correctly. Only retail stores should tint colours in tint bases according to the formulation on the Plascon tinting machine.

  6. Good Morning,

    I have previously used “RUSIST’ to pre-treat / cure numerous rusted galvanised roof rust patches in Springs, Gauteng. Your DIY Ask Us pages state that Polycell ‘End Rust’ Cure IS NOT suitable for Galvanised roofs application as roof temperatures exceed 65°C and that polymer content cannot stand the stress.

    Kindly advise product name and supplier of an alternative product to clean up and pre-prepare my IBR 0.8mm sheeting that has been previously hail damaged and allowed growth of rust patches, corrosion and growth of density of rust patches.

    Regards, Bill

    • Hi Bill, thank you for your query.

      For galvanized iron roofs you’ll need to sand the rust back to bright metal. Our rust removers are not recommended to be used on galvanized roof as they will destroy it. After sanding the rust you’ll need to clean the surface with Plascon Galvinzed Iron Cleaner, rinse thoroughly with water, and allow the surface to dry completely. Spot prime the bare areas with our Plascosafe Waterborne Primer, which is an anti corrosive primer for metal. Allow this to dry for 8 hours before over-coating it with our two coats of Plascon Nuroof Cool.

    • Hi Louise, we unfortunately do not manufacture pine gel and do not know how it will react on grouting. If you have the manufactures details perhaps you could contact them and they might be able to advise.

  7. How can I remove PVA paint from melamine cupboards? Will Woodcare Coating Remover for Wood do the trick or do you have a product that is better suited?

    • Hi, either Woodcare Coatings Remover or All Purpose Coating Remover would be able to remove the paint. Conduct a small test patch in an inconspicuous area to ensure product performance. This will indicate the time required for project completion.

  8. Hi Plascon,

    I have 4 grotty filing cabinets that I want to paint. They have some rusting on the tops – old adhered masking tape and scratches through the original paintwork to the metal sheet. I am painting the office in Plascon Winter Haven Cashmere and would like to do the cabinet drawer fronts in this colour and the frames in Old Ivory. How would I clean/prep/prime and paint the cabinets to get a professional long-lasting job? No spray painter on hand here. Oh and I live in Zambia – we do have a Plascon store but they do not stock all of your products that you have in S.A.

    • Hi Mafundzalo, thank you for your patience! Here’s what you need to do:

      1. Remove the old masking tape.
      2. Sand the surface well to remove all rust, take out scratches and to create a key. Dust off thoroughly.
      3. Patch prime all bare areas with UC501 (Metalcare Mild Steel Primer) before applying 2 coats of Velvaglo.
      4. Observe drying time of at least 16 hours between coats, including the primer.

      • Thanks so much for your help on the filing cabinets.
        Would you be able to recommend how to paint Lever arch files that come with the slightly plasticised surface? Would a rub with wire wool and then velvaglo work well?

        • Hi Mafundzalo, unfortunately that’s a tricky one which we can guarantee. We do not have any product from the Plascon Range that can be used on plasticised surface. However a company that might be able to help is Duram (0800 500 222). They deal with glass and plastic furniture coatings.

    • Hi Paul, Plascon does not recommend painting slate tiles as they are not porous and therefore have no adhesion properties. In other words a long-lasting finish cannot be guaranteed. If you wish to go ahead then yes – the outcome will be similar with either technique.

      • Hi Plascon

        Thanks, I called your help-desk and they said you do not recommend this and do not have a product for slate roof tiles. I had it sprayed about 10 years ago, included a anti fungal element in the paint and it came out really well. It has faded a bit now and hence the reason for re-painting it. Can you recommend a paint or product outside of your own?

        Regards
        Paul

  9. Hi, Just bought a house and the previous owner painted the whole house inside with enamel. Do I need to scrape it down or can I just put universal paint over it and repaint? Thanks

    • Hi Johan, thanks for getting in touch. Here’s what you need to do:

      1. Ensure the surface is clean, sound and dry
      2. Sand lightly to create a key and dust off
      3. Apply one coat of Plascon Universal Undercoat allowing 16 hours drying time
      4. Finish with two coats of your chosen water-based topcoat

  10. I want to paint a new sign for the entrance to our Complex. I have a panel of Chromadek (2.5m x 600mm). What should I paint the letters of the name with? Do I need a primer first?

    • Hi Garth, here’s what you need to do:

      1. Clean the surface thoroughly with Polycell Sugar Soap Powder solution or Removall High Strength Cleaner & Degreaser with scouring pads to remove chalk, grease and grime.

      2. Rinse thoroughly with clean water to neutralise and allow to dry.

      3. Prime with Epiwash Strontium Chromate Primer, then paint the letters with Wall & All – an extremely durable, washable, pure acrylic emulsion sheen paint for interior and exterior use.

  11. We have recently installed new rhino board ceilings. Once painted it has a ripple look. Do you have a product to eliminate the ripple look?

    • Hi Ashok, thanks so much for getting in touch.

      The surface you describe should not have a ripple look to begin with. This is only achieved by using a ripple roller. Could you kindly specify what products and application tools were used initially? Was any primer used?

  12. Can I use Water Based Velvaglo on my steel window fames that have been previously painted with enamel? Because I’m going to use Velvaglo on the wooden window sills, just near by.

    • Hi Tony, thank you for your query.

      Yes you may use Water Based Velvaglo on surfaces previously painted with enamel. Simply sand to a matt finish, dust off then finish with two coats of Water Based Velvaglo – allowing 4 hours drying time between coats.

  13. Hi, please advise, is there any products or paint which is recommended to restore the look / top coating of a stone-coated roof tile that has turned pale, dull and ugly (using spray paint application)?

  14. I have sanded pine facia boards and 80% of the wood has been bared. I want to apply Velvaglo white as a finish coat. What priming and undercoating is recommended for best results?

    • Hi Hugh, thanks for getting in touch with us. Here’s what you need to do.

      Prime with Plascon Wood Primer and allow it to dry for 16 hours, then finish with two coats of Plascon Water Based Velvaglo – guaranteed for exterior use and used as a decorative and protective finish on interior and exterior primed woodwork. Plascon Water Based Velvaglo is a unique polyurethane acrylic hybrid that forms a resilient barrier that is UV, peel and flake resistant. Please find attached Technical Data Sheets for the products and refer to Surface Preparation, Application and Cautions.

  15. How do I prepare my kitchen wall to paint after removing tiles that left it in a bad state?
    I’m going to paint the walls light gray with Velvalglo.

    • Hi Wanja, thank you for your query.

      Firstly we need to understand how bad the condition of the walls are currently. Is it raw plaster? An uneven surface? If possible please send us clear pictures of the wall to advice@kansaiplascon.co.za in order for us to give correct advice. Please also advise us what it is that you are looking to do – e.g. do you want to skim the walls first before painting or what is it that you want to achieve?

  16. Hi there. We recently bought a house that is walled in with vibracrete walls. These are very old walls which have never been painted. How do I go about prepping the surfaces for painting and what primer/paint should I use? The front wall however is brand new vibracrete. Do I use the same methods for prepping and painting this particular wall?

  17. Good day, I bought 20 litres of Grey Steel 2, but after one wall was painted I find it too dark and too BLUE or purple. Is it possible to add some other colours to the mixture to “correct’ my problem? Painter waiting for an answer right now… 🙂
    Thank you, Eon

    • Hi Eon, thank you for getting in touch with us and apologies for the late response (our webmaster was on leave).

      With regards to “Grey Steel 2”, we are not certain if you are referring to a product name or a colour? If it is a Plascon colour tinted into a Plascon product, we unfortunately don’t recommend manipulations of our formulas. We therefore cannot advise you to add certain colourants to make the colour lighter or darker as each Plascon colour is proven and tested by our colour lab which then provides us with the fourmula for each and every colour.

      We can however suggest getting in touch with the Plascon Spaces Showroom, which is where our colour experts can advise you. Ask for Claire Bond. She is very helpful with these sorts of things 🙂

  18. Hi Guys. We are currently paining our house using Plascon Micatex. Our painter has gone and painted our aluminium door frames. It was painted a week ago so it has had time to dry well.. Is there any way to clean it off without damaging the aluminium door frames?

  19. I have a house that is 35 years old. The house was painted with PVA. I would like to know what is the best way to get rid of the old paint. It is flaking in some parts and other parts stick like glue. I have done one room and the hallway by scraping it off with a scraper. Took ages. Can you please assist? Regards Pierre

  20. Please would you tell me if there is a water based primer to use on shutterboard wood that will stop the resin stains bleeding through a coat of acrylic gesso. I want to paint on the wooden boards but the stains bleed through the gesso and I have heard that the stains will bleed through subsequent coats of gesso. The primer must be one that the acrylic gesso will adhere to properly. Thanks.

    • Hi Gail, apologies for the late response. We have been having system problems from last week. We regret to inform you that Plascon does not have a product that will stop the resin from bleeding through.

    • Hi Brett, thanks for getting in touch. Unfortunately Plascon does not have a product for such an application. We can however suggest contacting a company called Coprox who specialise in such. They can be contacted on 011 579 4300.

    • Hi John, thanks for getting in touch with us. Here’s what you need to do:

      1. Clean / Degrease thoroughly with No.40 Lacquer Thinner, then abrade with 150 – 220 grit paper to provide a key.

      2. Wipe down again with No.40 Lacquer Thinner then apply 1 coat of Plascoprime Self Etch Primer.

      3. Lastly, apply 2 coats of Plascon Waterbased Velvaglo.

      Please note that due to the roll up action of you door the paint will crack over time.

  21. HI I would like to find out, our walls are painted with enamel paint, when we use the undercoat and then the PVA paint, is there a specific PVA paint that we need to use over the undercoat? Please help and please advise, thanks.

    • Hi Cleo, thanks for connecting. Here’s what you need to do:

      1. Remove loose and flaking paint back to a sound substrate and a firm edge by scraping and sanding.

      2. Spot prime bare areas with appropriate primer. Clean with POLYCELL SUGAR SOAP POWDER solution to remove all contaminants.

      3. Rinse with clean water to remove all traces of SUGAR SOAP and sand glossy enamel surfaces thoroughly to an even matt finish, dust off and apply one coat of PLASCON UNIVERSAL UNDERCOAT.

      Please note thatyou can use Plascon Double Velvet, Cashmere and Polvin for interior walls.

  22. How do I remove spray paint from a very thin copper sheet? Is Plascon’s Coast Coat Etch Primer suitable to spray on a thin copper sheet, used to retain heat inside a solar panel heat collector application? Where can I get a specification sheet of the aforementioned paint?

    • Hi Andre, thank you for your query. One can lie the items in a strong solvent such as lacquer thinners Please note that A grade do not use a paint remover as this would edge into the copper. Unfortunately Plascon do not have a coating that would successfully adhere to copper.

  23. Hi, what paint should I use for old white interior doors which have knocks and dents in them? (I have filled the holes with wood filler which I then sanded – but the marks will still be visible if I use an enamel paint).

  24. 1. What do I need to do to paint a recently varnished knotty pine ceiling white?

    2. I have a rough cement floor which has been sealed numerous times. It seems like the sealant is pealing off. What can I use to properly and permanently seal the floor?

    3. I have cheap hardwood doors that I want to paint. Can they be painted?

    • Hi Jaci, thank you for querying. Please see below:

      1. Completely remove paint by most appropriate means e.g. scraping, course sanding or stripping with RemovAll All Purpose Paint Remover. Wash thoroughly with Polycell Powder Sugar Soap solution. Rinse with fresh water. Sand smooth with 150 grit paper working in the direction of the grain and dust off. Seal knots and resinous areas with Plascon Knot Seal. Prime entire surface with Plascon Wood Primer. Finish with your desired top coat.

      2. Where is the cement floor? Is it interior or exterior?

      3. Yes, they can be painted. You may use Plascon Plaster Primer or Plascon Wood Primer. We recommend the Plaster Primer for supa-wood or wood that is manufactured in a factory. Hardwoods that contain a lot of glue do not absorb Plascon Wood Primer well. Once the topcoat is dry you may use any topcoat.

  25. Good evening, I want to paint my headboard and bedside table. Want the distressed look. What’s the best method and what will I need to do that?

    • Hi Chanelle, thanks for getting in touch with us. For any advice regarding paint techniques, please send an email to our Plascon stylist Claire Bond (claire.bond@plasconspaces.co.za). She will be more than happy to assist you
