The Ultimate Heavy-Duty Barrier against Severe Contaminants
INSL-X® Max Block® Alkyd Primer-Sealer is a core restoration product built to conquer the most stubborn surface bleed issues. Waterborne primers often dissolve and lift wood tannins or old smoke residues, carrying them up to stain the fresh topcoat. Max Block’s oil chemistry forms a non-porous shell that locks those water-soluble stains deep below, guaranteeing color accuracy for your premium topcoat paint.
Best Used For:
• Severe exterior wood tannin blocking on cedar siding, fences, and redwood decks
• Heavy interior fire, smoke, soot, and water-damage restoration projects
• Sealing out deep grease stains, crayon, marker ink, and dried pet stains
• Priming aged, weathered, or unpainted wood panels, trim, and architectural concrete
