Painting Ceilings and Walls DIY

Something important to remember whenever painting ceilings, walls or any paintable surface:

  • Painting Ceilings DIYAll unpainted surfaces must ALWAYS be primed.
  • Priming previously-painted surfaces are handled according to the topcoat selection and will be required, depending on the existing paint coating on the surface / substrate.

Here are some basic rules to remember:

Repainting a previously-painted surface which has been painted with a water-based paint:

  • Enamel Paint – depending on the condition and quality of the water-based paint used before, a primer may be required because low quality paints may need consolidation with a penetrating primer.
  • Water-based Paint: No primer or undercoat needed.

Repainting a previously-painted surface which has been painted with an enamel paint:

  • Enamel Paint: No primer BUT undercoat required.
  • Water-based Paint: No primer BUT undercoat required.

  1. What filler can I use for fine cracks (wind cracks) on exterior plastered walls? The walls are 18 months old, painted with Wall and All. Ideally some sort of penetrating (capilliary) product, as the cracks are very thin?

  2. Good day, what procedure should I use for walls that have been painted with orange enamel paint? I want to use PVA matt white. Please could you assist me.

  3. Hi, I need to paint a polystyrene cornice for the first time. Please advise on paint and brush to buy.
    Regards, Edith from Pretoria

    • Hello Edith from Pretoria. You can certainly paint a polystyrene cornice with a water-based paint like Polvin Walls & Ceilings. You will just need to make sure that the surface is free from dust before applying the paint. It will also require up to 3 coats because the polystyrene will absorb the paint.

  4. Good day, I hope someone will be able to assist me. Our dining room, lounge and entrance hall have a knotty pine ceiling. The previous owners smoked in the house and the smoke has pulled into the ceiling making it very dark. I would like to paint the ceilings white and would therefore like to know if there is a primer or a similar product that I can paint onto the ceiling before painting it white? Or will I need to sand the ceilings first? Regards Daniele

    • Hi Daniele, thanks for reaching out to us. Here’s what you need to do for previously-painted or varnished wood:

      1. Remove old paint/varnish by sanding. Sand the wood in the direction of the grain to a smooth finish. Dust off thoroughly and seal knots with Plascon Woodcare Knot Seal.

      2. Apply Plascon Wood Primer allowing 16 hours drying time. Finish with two coats of a Plascon interior paint.

  5. Bought the Modo Pink 2 White ceiling paint. It’s not really pink, so light you can barely see it anyway. And so thick, makes application difficult. Thought it is a dark pink colour so you can see it?

    • Hi Dedre, sorry about the colour issue you are experiencing. Pink 2 White is specifically made to change from pink to white upon drying. The reason for this is so that it allows you to see the painted area even under low light.

  6. I have to paint the walls and ceiling of an old house that has been painted with enamel gloss paint. What preparation do I have to do if I want to re-paint with Velvaglo? I need an easy way of removing bitumen from the floor. What preparation do I need for tiling with ceramic tiles on the same surface?

    • Hi Figan, thanks for getting in touch.

      When using Velvaglo Enamel you can just wash the surface with Polycell Sugar Soap. Allow this to dry and apply 2 coats of the Velvaglo Enamel. Using the Velvaglo water-base you can wash the surface and allow to dry. Apply 1 coat of Plascon Universal Undercoat and allow to dry for 16 hours. Thereafter apply 2 coats of the Velvaglo water-base.

      Unfortunately for the bitumen floor you will need to contact African Bitumen Emulsion 011 306 9000.
