To get the best results, ensure surfaces to be painted are sound, clean, dry and free of dust, dirt, excessive chalky material, grime, oil, wax, mould, wall paper adhesive or any contamination that may interfere with adhesion. If unsure, always wash the surface with a household cleaner, appropriate cleaning solution, or methylated spirit and rinse off.
- Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead
- Clean new galvanised with methylated spirits, remove any unsoundly adhered coatings, sand any remaining paint film edges smooth and level the surface
- New plaster which is polished or dusty should be abraded to open the surface. Lightly sand exposed exterior wood with 80 to 100 grit sandpaper to remove loose or weathered wood fibres
- When priming over stained areas, first attempt to remove as much of the stain as possible by washing and sanding
- Remove mould and treat area with Fungicidal Wash.
- Remove rust, wire brush rusty areas and wipe surface clean with methylated spirits.
