Thorndown Stain Blocking Primer is a high performing multi-surface primer primarily developed for tannin and stain blocking on timber surfaces. It’s formulated to work on all softwood and hardwood including pressure-treated timber, Accoya, Iroko, plywood, MDF and hardboard. Thorndown Stain Blocking Primer blocks stubborn and persistent stains including water stains, marker pens, and seals porous surfaces with excellent blocking of bleeding knots and sap streaks.
Thorndown Stain Blocking Primer also contains flash rust inhibitor to stop rust forming and fungicide film preservation to stop paint film degrading with mould. It’s easy to keep your paint job looking great by applying a base coat of Thorndown stain blocking primer first, stopping tannins from wood coming through and staining your paint coating. For use on any wood, anywhere.
