Protek Stain Blocking Primer Protek Stain Blocking Primer

• Protek Stain Blocking Primer MUST be fully dry before applying the top coat. 

• Brushes must be fully washed out before using with the top coat. 

• In their wet forms Stain Blocking Primer and other top coats are not compatible and should never be mixed.

Surfaces should be clean and dry before application.  If surfaces need to be cleaned we recommend warm water with detergent and a stiff brush. 

 

Mix well before use. Protek Stain Blocking Primer can be applied by spray, brush or roller. Allow each coat to dry before applying the next; this should take up to 1 hour.  We recommend 2 coats especially if a white or off-white topcoat is being applied. If applying to bare untreated timber we recommend first applying a 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.
