Semi-matt, waterborne primer for new or previously treated wood.
Effective barrier against bleed-through from knots, lignins, nicotine, water stains, etc.

For use indoors on all types of woodwork such as mouldings, panelling and ceilings and also on plaster and drywall surfaces.
Very suitable for pine panelling where any wood grain and knots tend to bleed through water-based primers and topcoats.

Use at least 1-2 coats with at least a 6-hour interval between coats (always use 2 coats on knots).
The surface should be clean, dry and sanded to a matt finish before painting.
Then paint over using waterborne paint for your final topcoat.

Warning information for chemical products
May produce an allergic reaction.
