  1. I have Supawood Wrap cupboards in my kitchen – can I paint over these and do a technique on them? If so, how do I prep the surface and what paint do I use?

    • Hi Susan, thank you for your query.

      The Supawood wrap can be various wraps from melamine, plastic or veneer. It’s important that we see the substrate before we can recommend a primer and topcoat.

      Please could you get in touch (and possibly send us a picture) via the Plascon Advisory Service? The email address is advice@plascon.co.za

  2. Hi,

    My house is a facebrick built house which has been painted.

    What would be the best paint to use to repaint the house? What would the spread required be?

    Thanks

    • Hi Dan. To be able to provide / suggest a coating that can be used on your house, we will need to know what the exact coating is that was last used as well as the current condition of the coating?

  3. I have plastered and painted (PVA I assume) boundary walls. Large areas of paint scraped off due to dampness. I have also had some cracks opened and plastered.

    1. How do I handle this with specific reference to “mapping” effect where portions of existing paint removed ie to smooth it again prior to painting.

    2. Do I use plaster primer where plastered 1st prior to Dampseal?

    3. Is Micatex the best exterior application for boundary walls ?

    • Hi Joe, thanks for getting in touch.

      The first thing we need to establish, is what is the problem that caused the damp issues? There will be a lot of follow up questions we need to ask to make sure the extent of the damp can be treated with our products. Would you mind providing us with a contact no. so our experts can get in touch with you? Alternatively, you could call our Customer Care line on 0860 20 40 60.

  4. Hi, Help! I wanted to whitewash a free-standing cupboard and needed to stain it teak after sanding it down. I sadly used an oil-based stainer instead of water-based and don’t want to paint over this! I find it’s taking forever and keeps clogging my sandpaper. Is there an easier way, maybe a product I could use to take most of it off? Your help will be appreciated. Thanks Jackie

    • Hi Jackie, thanks for reaching out to us.

      In order for us to advise you, please could you provide us with the exact product details on what oil-based stainer was used? If you could include the product name, product code etc. that would be super.

  5. I really like the DIY info but why does surface preparation only deal with some products and the top of the range products like Double Velvet and Cashmere where one wants the best possible result are not mentioned? Or have I overseen something?

    • Hi Steve, thank you for your observation / suggestion. This page is a work in progress and there are several additional Plascon products (incl. a few new ones) that need to be added. Watch this space!

  6. Hi, the interior of my house is a rough plastering surface. Is there a DIY way to transform it to a smooth surface (e.g. like using a scraper and sand paper and maybe a filler I can use to smooth-en the surface)? Please help, I am about to move into this house but I would like to prep it before moving.

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

      Firstly please note that new plaster has to be left to dry for at least 28 days. Once dry, ensure that the surface is clean sound.

      For skimming of raw interior plastered walls, we recommend Terraco Handycoat EZ Skim Interior (TER 1200).

      Step 1: Using a scraper or steel trowel scrape off any plaster splashes or foreign material from the substrate to ensure an even surface. Brush the scraped surface using a soft bristle brush, e.g. block brush, to remove all dust and friable material from the surface.

      Step 2: Apply the 1st layer of Handycoat EZ Skim using a steel trowel. Apply the material (approx. 1mm) as per standard plastering method. Level (skim) the applied material to achieve an even surface. Do not exceed 2mm per layer. Allow to dry for approximately 1 hour.

      Step 3: Apply the 2nd layer of Handycoat EZ Skim (approx. 0.5-1mm) and finish to a smooth and level surface. The second coat application will consume less material than the first coat application. Allow product 4 hours drying time depending on application thickness and ambient temperatures and conditions. Ensure to clean all tools with clean water after use. Be sure to dry all the equipment to prevent rust.

      Step 4: Lightly sand using a 320 grit sand paper to remove any high profiled material to achieve a smooth level surface required for painting. Brush the sanded surface using a soft bristle brush, e.g. block brush, to remove all dust from the surface.

      Step 5: We recommend overcoating with Plascon Double Velvet. Please refer to the Surface Preparation in the technical data sheet.

      Note: There is no need to prime the surface before or after the application of Handycoat EZ Skim.

  7. Hi, I’m busy redoing my garage. There were a couple of patches where old paint has started to peel off, so I started scraping them and now I have a room with some patches of plaster, some patches of the really old paint, green and some of the the original paint. How much do I have to prepare the surface, take all paint off, or can I just smooth it off by sanding and prime and paint?

    • Hi Mark, do you have a oil or water-based paint? If you have a water-based paint: Sand to a smooth finish then degrease the surface by using Plascon Aquasolv Degreaser. Rinse thoroughly with clean water. Allow to dry for at least 48 hours until totally dry. Then apply one coat of Plascon Concrete Floor Prep only to the bare areas. Allow the surface to dry for 8 hours before applying 2 coats of Plascon Floor Paint.

      If you have an oil-based paint :Remove all of the paint then degrease the surface by using Plascon Aquasolv Degreaser. 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. Allow the surface to dry for 8 hours before applying Plascon Floor Paint (FPT Range).

  8. I have redone a plastered boundary wall. I had to redo it because of damping in the plaster. Please could you advise me on the preps to take and different products to use to avoid a future repeat?

    • Hi Junaid, thank you for querying.

      You will need to wait for at least 28 days for the plaster to be fully dried before you can apply any primer/paint to the wall. also make sure you have plastered the top of the wall.

      You will need to first ensure that the surface is clean, sound and dry. With plaster cracks (less than 4mm) open cracks to a minimum of 3mm wide and deep, remove dust and prime inside of crack with Plascon Plaster Primer and allow it to dry for 16 hours. Fill cracks with Polycell Polyfilla Mendall 90 using a scraper, smoothing off whilst still wet. Sand smooth after 8 hours then patch-prime repaired areas with Plaster Primer and allow the primer to dry for 16 hours.

      Apply one coat of Plascon Multiseal over the repaired areas and hairline cracks and leave it to dry for 4 hours and then finish with two coats of Plascon Micatex. This is a finely textured exterior matt paint, formulated for protection against the toughest weather conditions and also contains “mica for stretch and marble for strength” to cover and prevent hairline cracks. Micatex also comes with a 12 year quality guarantee which you need to register with us within 30 days of purchasing the product.

      If you have rising damp (which is only 1.1meters above ground level): Ensure that surfaces are clean and sound before painting. Surfaces may be slightly damp but not wet. Remove any paint completely back to the bare substrate. Remove loose and friable material to achieve a sound surface. Re-plaster with cement plaster if necessary.

      Remove any oil and grease with Polycell Sugar Soap. Rinse thoroughly and apply 3 coats of Plascon Dampseal, allowing 24 hours drying time between coats. Thin the first coat 3 parts of Plascon Dampseal to 1 part Mineral Turpentine by volume. Plascon Dampseal may be over-coated with Micatex.
