Johnstone’s Trade Aqua Guard Primer Undercoat is an innovative, water-based primer and undercoat that is ideal for interior wood. It has excellent adhesion to previously painted surfaces and most porous substrates. When used over bare timber it prevents resins from staining through into the finish. It acts as the perfect undercoat to the Johnstone’s Trade Aqua Guard Gloss, Satin or Matt finishes, with excellent opacity and adhesion.
