Overview
Overview
Back
Protek Stain Blocking Primer is an effective base coat for stains caused by tannins, pressure treatment chemicals and rust from nail heads. It can be used at low temperatures and is fast drying.
Please Note: If applying to bare untreated wood, it is recommended to use a water-based wood preserver prior to application, like Protek Wood Preserver Plus
When treating resinous timber, a knotting agent will need to be applied to stop the resin from knotts seeping through the top coat.

Good, easy to apply
During Covid lockdown I had to build bookshelves out of scrap floorboards. This coped well with blocking the stains from nail holes and as a base for the Protek Royal Interior paint.
