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.

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.

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.

What is the difference between Wall & All and Double Velvet?

Plascon Wall & All is extremely durable, washable, pure acrylic emulsion sheen paint for interior and exterior use, with an attractive suede sheen finish which has exceptional exterior durability also has unique Dirt Barrier formulation that protects exterior walls by inhibiting the growth of mould and fungus. Plus it delivers superior dirt resistance.

Double Velvet is a low odour premium quality interior velvet sheen wall coating that is highly washable and stain resistant. Hero Ingredient: unique stain barrier that forms a multi-layered protective coating preventing dirt from penetrating the paint. Silver protect technology provides antibacterial (Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus), yeast and fungal protection to the painted surfaces. This protection helps to maintain a hygienic environment by eliminating these micro-organisms within 24 hours of contact.

Please see the data sheets attached in the links provided for more info.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

How do you strip the paint from a wooden piece of furniture to go back to the natural wood, and what should you seal it with afterwards?

  • Apply Plascon Removall Coating Remover for Wood (RWI 220) applied thickly over the old varnish/paint. Allow to react for 2 hours then scrape off. Repeat on “Stubborn Areas” until Varnish/Paint 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 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.

  1. I have used suede effects paint but had it tinted too dark. I’ve done two coats as advised on tin. The wall is almost black and looks like a blackboard. HELP! Any suggestions?? Can one paint over it to lighten the colour as the suede effect is totally lost. It is just one wall. My inexperience!!

    • Hi Jacqui, worry not, we’re here to help!

      The good news is: yes, you can repaint the wall with a lighter colour in our Suede range. You will unfortunately have to sand the current coating back to a smooth finish and remove all traces of dust. Then apply one coat of universal undercoat; this will ensure the lighter colour will hide the current dark colour. Allow this to dry for 16 hours, and then you can apply your first coat of the Suede undercoat.

      All the best!

  2. I bought 4×20 litres of Plascon Micatex White more than 2 years ago. I would like to know whether the paint is still good enough to paint a house?
    Yours sincerely
    Carine

  3. I love all the adverts on FB seeing what can be done with Plascon paint. As someone that does a lot of different hobbies and often needs paint to paint small objects, my question is can Plascon not produce smaller containers for paint for us as it becomes too pricey if you have to buy big tins of paint?

    • Hi Rosa, thank you for your query and for your kind words re our Facebook adverts!

      Plascon does produce 250ml Tester Pots, which can be tinted into various colours, however these containers are waterbased and come in Double Velvet (sheen finish) and Cashmere (plush matt) finish only. They are available at most hardware and paint outlets. These are just not available in enamel (gloss). Most of our solvent based products are available in 1lt containers also.

  4. Good day, I would like to repaint my kitchen cupboards, melamine not wood. They are in a very good condition … I just don’t like the colour. Is this possible? Please advise! Thank you

    Kind regards,
    VB

    • Hi Visnja,

      Thanks for getting in touch.

      Plascon manufactures a Tile and Melamine Primer suited to your needs. Here are the steps:

      1. Wash melamine cupboards with a solution of sugar soap to remove any contaminants such as oil, fingermarks etc. For firmly adherent cooking oils in kitchen areas, use Aquasolv Degreaser and rinse thoroughly with water.

      2. Allow to dry and apply 1 solid coat of Tile and Melamine Primer ensuring that the surface is well covered. Apply 2 coats for best results.

      3. Allow 2 to 4 hours to dry (note that drying times are retarded this time of year due to increased moisture levels).

      4. Allow the first coat to dry thoroughly, then sand lightly with a fine paper and wipe clean before applying the second coat. Sand the primed surface lightly before application of the topcoat.

      5. Once the primer is dry you can either paint with Kitchen and Bathrooms or Velvaglo in a colour of your choice. Apply 2 coats and follow the overcoating times as per product.

  5. Can Plascon’s METALCARE RUST CONVERTER & PRIMER be used on cast iron? Can it be used on sheet metal?

    • Hi James, thank you for your query.

  6. Good day,
    I plan to redo my wooden floors in my house. I have treated the floors 10 years ago with puc 1. I would like to know the difference between puc and pfv floor varnish and which is best. I have about 96m2 and plan to sand it down to the plain wood again. Please advice on prep.
    Thanking you in anticipation.

    • Hi Moses, thanks for getting in touch.

      PUC1 is a single pack moisture cured urethane floor coating, which has a smooth high gloss appearance.

      PFV is a top quality hard wearing interior clear floor coating that is highly resistant to abrasion, alcohol, water, food, stains, grease and detergents.

      Our experts suggest that you use Plascosafe Waterbased Floor Coating-Clear (WFC) – which is part of our Industrial Range of products.

  7. Do I have to remove all the varnish from a cane chair before painting a PVA undercoat? I want a matt washed beach look

    • Hi Liset, unfortunately there is no product that we can recommend for use on a cane chair. Contact Specialized Coatings on 086 137 2468 – they might be able to assist.

  8. Hi, I would like to paint an ugly bathroom mirror frame in an ‘antique’ look. The frame is a sealed / varnished wood. Do I have to sand the wood first and what is the simplest technique to use, and best budget-friendly paint option? Thanks

    • Hi Shirley, that’s a great look to give old mirror frames. We have a whole page dedicated to Paint Effects (please click on link) and have a look at the “Distressed Frame” one. If this is not quite what you’re looking for our experts over at the Plascon Spaces Showroom would be happy to assist you! GIve them a call or drop them an email

  9. I’ve just painted an old server with white Velvaglo Enamel paint. Can I use Plascon Pearl Paint over it? If not, how can I rectify the painted area?

  10. I am trying to find the name for the shade NEU01 – and can’t find it anywhere… can’t seem to order more of the same shade unless I know the name or alternative code.
    Thanks.

    • Hi Meg, I have just tried looking for that colour using the Plascon Inspired Colour System and it seems that the code is either invalid or is not a part of the system.

      I can advise 2 options: either to email the Spaces Showroom and ask them or to use the InspireMe App. Have you heard about this? It will allow you to snap a pic of the colour you are wanting and provide you with the closest match (as well as adjacent and complementary colours).
