Painting outdoor walls

What should you use is the first question we all ask ourselves? Well let’s see why do we need to paint? The outside of your property could be looking tired and by painting it can make a dramatic difference to not only its appearance but also to its value. The main reason why we paint is to either beautify or protect the surface.

Therefore we should always say how do my walls look?

Here we will look at six different substrate conditions and what we should use:

  1. New: Make sure your plaster is dry. Plaster should be left to dry for 21 days before applying a plaster primer to it. We recommend using an Artisan plaster primer and then leaving it to dry for 24 hours. Plaster primer should not be left without a top coat for longer than this as it does not contain any UV stability to it and will just break down in the sun, giving no protection or adhesion to your top coat. Depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.
  2. Previously painted and sound: If your walls are still looking good, not cracking or pealing just spray walls with a pressure cleaner, leave to dry, depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.
  3. Flaking: Start by scraping all loose bits of paint with a 75mm scraper, sand surface smooth with 80grid sand paper. Use pressure cleaner to remove dust and any other loose bits. Leave to dry. Apply one coat Artisan Plaster primer to bare wall areas, leave to dry for 24 hours. Plaster primer should not be left without a top coat for longer than this as it does not contain any UV stability to it and will just break down in the sun, giving no protection or adhesion to your top coat. Depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.
  4. Cracks: Open all cracks in a V-shape with a 35mm Scraper. Apply to bare cemented areas Panache Primer Cure. Leave to dry for 24 hours. Primer Cure is a damp treatment and should not be left without a top coat for longer than this as it does not contain any UV stability to it and will just break down in the sun, giving no protection or adhesion to your top coat. Fill cracks with a ready mixed filler, leave to dry and sand smooth with 100grid sand paper. Apply over filler areas one coat Panache Primer Cure to seal, leave to dry. Depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.
  5. Mould: Wash down mouldy areas with a Mould Buster, rinse with clean water afterwards to remove soapy residue. Once area is dry apply one coat Panache Primer Cure and allow drying for 24 hours. Primer Cure is a damp treatment and should not be left without a top coat for longer than this as it does not contain any UV stability to it and will just break down in the sun, giving no protection or adhesion to your top coat. Depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.
  6. Chalking: Wash walls down with a scouring pad and some Sugar soap to remove powder from substrate. Rinse with clean water afterwards to remove soapy residue. Leave to dry. Apply one coat Panache Bonding liquid. Leave to dry for 18 hours. Bonding liquid should not be left without a top for longer than this as it will become glossier the longer you leave it and will not allow any adhesion of top coat. If this has happened use a Scouring pad to remove the gloss and apply a Universal Undercoat to the painted area, leave to dry for 24 hours. Universal Undercoat is an intermediate coat and allows you to change a painting system for better adhesion and should not be left without a top coat for longer than this as it does not contain any UV stability to it and will just break down in the sun, giving no protection or adhesion to your top coat. Depending on your plaster finish we recommend using a Panache or Artisan top coat. If your plaster is smooth with very little imperfections use Panache Vinyl Silk or Artisan Satin cote. If your plaster is showing some imperfections use Panache Tufftex as this is a smooth textured product it will hide imperfection and also cover hairline cracks.

Hope these will help you to identify your walls and so assist you with your upcoming projects.  Happy Painting…
