Protek Stain Blocking Primer can be applied by spray, brush or roller and dries within an hour. Two coats are recommended if applying a white or a light colour top coat. If applying to bare untreated timber we recommend first applying Protek Wood Preserver ++ before the primer. This primer will stop the tannin bleed from knots in the wood but it will not stop the resin coming through. If the timber is resinous a knotting agent should still be applied to the knots. Protek Stain Blocking Primer must be fully dry before applying the top coat. In their wet forms Stain Blocking Primer and other top coats are not compatible and should never be mixed.
