Stain Blocking Primer Application Guide

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 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 water-based wood preserver before the primer. This primer will stop the tannin bleed from the 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.

SURFACE PREPARATION: Processing temperature: 5-30C (wood and product)
COMPATIBILITY: Protek Stain Blocking Primer MUST be fully dry before applying the top coat. Brushes must be fully washed out before using the top coat. In their wet forms Stain blocking Primer and other top coats are not compatible and should never be mixed.
STORAGE: If correctly stored and kept in the original sealed container (cans), the shelf life as at least 24 months. Temperatures above 30C and below 5C should be avoided. Before use it must be ensured that the product is at a temperature between 0C and 30C.
DISPOSAL INFORMATION: Dispose of in accordance with local regulations.
SAFETY INFORMATION: Please read the Material Safety Data Sheet>
