Wash down previously painted surfaces with a detergent solution to remove dirt, grease, etc. We recommend Farbex Multi-Surface Preparation or Protect-it Cleaner Reviver).
Rinse off with clean water and allow to dry.
Use a wire brush or paint scraper to scrape back to a firm edge any areas of poorly-adhering or defective coatings and rub down thoroughly to ‘key and feather’ broken edges of existing coatings.
If necessary fill in any cracks or holes with a suitable exterior filler. We recommend Prestonnett Exterior Filler either Quick Dry or Waterproof Exterior Filler.
Treat any mould with a Fungicidal Treatment. We recommend Farbex Multi-Surface Cleaner.
If you have a chalky surface or a very porous surface use a stabilizing solution to seal and stabilize before painting to help masonry paint adhere well.
Lay down dust sheets under the area you will be painting to avoid any paint splatter staining the ground and cover any plants beside the wall. If painting a house wall, protect any doors and windows with masking tape and dust sheets.
You can use a brush or roller when painting smooth masonry. Specially-designed masonry brushes and rollers hold more paint and will make the job easier. For medium to rough surfaces we recommend Wooster Rollers for very rough or dash surfaces with recommend a Corona Tuff Pro Roller Sleeve.
If the wall has never been painted before, thin down the first coat so it acts like a primer. The manufacturer’s instructions will tell you how much thinners should be added to the paint. On previously painted walls there is no need to dilute the first coat.
Using a brush, cut in with the paint around all the edges on the wall e.g. capping stones, pillars. If it’s a house cut in around the windows and doors first. Start at the top and work your way down.
Use a roller to paint the rest of the wall. Start at the top of your home and roll downwards. Paint the wall in sections and only move on to the next section when you are satisfied that the section you are working on is properly painted.
The normal finishing process is two full coats of masonry paint, but on previously painted surfaces in good condition, where similar colours are used, one coat may be sufficient.
We always recommend that you use the best quality exterior paints that is why we only ever recommend either Colourtrend Weather or Dulux Weathershield paints.
