Protek Stain Blocking Primer is effective at blocking tannins, pressure treatment chemicals and rust (from nail heads) bleeding through to the top coat. An excellent low VOC water based formulation based on a cationic epoxy resin, it offers better performance than both water based and solvent borne products currently available.

Recommended to be applied before using a light white containing colour on new timbers, to stop discoloration by bleed through.
