Preparation
Surfaces must be clean, dry and free from loose and flaking material, dirt, grease etc. Repairs should be carried out prior to painting. Areas contaminated with fungal or algal growth should be treated with a proprietary fungicidal wash or with 25% household bleach before painting. Surfaces previously treated with gloss paint should be thoroughly abraded before painting.
Application
Stir well before use. May be applied without thinning by brush, roller or airless spray. For use as a Wood Primer, thinning 5% with water is recommended with light rubbing down between coats if the surface is slightly rough. As a sealer on plaster surfaces thinning up to 25% with water will be required. On surfaces previously painted with Matt Emulsion, 15% thinning is recommended. Apply 1 or 2 coats as required. To obtain good flow, apply generously but avoiding runs and sags.
Clean up
Equipment should be cleaned with water immediately after use.
Precautions
Always read the can label before use. Do not apply to surfaces below 5°C or if there is a risk of heavy rain during application or drying.
