Insl-X Max Block Primer
INSL-X® Max Block™ Stain Blocking Primer | Professional Interior & Exterior Primer
In restoration and repainting projects, the success of the finish often depends on what happens before the first coat of paint is applied. INSL-X® Max Block™ Primer is engineered to tackle one of the industry's most persistent challenges: stubborn stains that continue to bleed through conventional coatings.
Developed for both residential and commercial applications, this high-performance acrylic primer provides exceptional stain-blocking capabilities on interior and exterior surfaces. From water-damaged ceilings and smoke-stained walls to tannin-rich wood siding and grease-contaminated substrates, Max Block helps isolate discoloration and create a clean, uniform foundation for premium topcoats.
For contractors, property managers, and renovation professionals, the ability to control staining issues without compromising efficiency is critical. Max Block delivers outstanding adhesion, excellent hiding power, and fast dry times to keep projects moving while reducing the risk of costly callbacks caused by stain migration.
