Brush, roller
1. Stir well before use with a broad flat paddle using an up and down scooping action.
2. Apply one coat of Dulux PRECISION® Stain & Mould Blocker.
3. For heavily stained surfaces on paper-faced plasterboard where there is a different texture between paper and joining compound, or where extra filling and smoothness are required, a second coat may be required.
Stain blocking:
• After priming, test for stain bleed-through by applying the topcoat to a small section.
• If the stain bleeds through the topcoat, apply a second coat of primer and test again before topcoating the entire area.
• If bleeding continues, a longer dry time is needed before topcoating.
Tinting: For stain blocking applications DO NOT TINT.
For use as a primer Dulux PRECISION® Stain & Mould Blocker may be tinted with up to 15ml (0.5Y) of Dulux Decorama® tinter per litre.
Tinting to a lighter shade than the topcoat is recommended
