Surface Preparation
Surface must be clean, dry, free from oils, surfactants, mildew and any other contaminants.
Remove as much chalky material as practical to maximise bond. Pressure washing is advised where possible. Mildew must be treated/ removed. Gloss surfaces, other than acrylic paint, should be keyed by sanding to dull.
Application
Stir before use. Thinning is not recommended.
Brush
Apply liberally in random pattern, thoroughly wetting the surface. Maintain wet edge across each surface.
Roller
Apply liberally, thoroughly wetting the surface. (Use lifting strokes while ponding sealer above roller). Cut and fill progressively to maintain a wet edge across each surface.
Spray
Spray light coats, wet on wet until surface is thoroughly wet. Airless spray is recommended. Mask surrounding surfaces
Clean Up
Water
Precautions
Ensure adequate ventilation during use. Protect from rain for at least 4 hours after application. Overcoating is advised within 7 days.
Maintenance
If the surface is damaged before overcoating, re-apply Sealer and Binder to restore film to match surrounding area.
Preparation to repaint
Before repainting, ensure surface is clean dry and unbreached.
