PROSOCO Interior Masonry Dustproofer – Water-Based Dust Control & Sealer (5 Gallon)

DUST CONTROL & PROTECTIVE TREATMENT

PROSOCO Interior Masonry Dustproofer is a ready-to-use, waterborne treatment designed to prevent dusting and protect interior masonry surfaces. It penetrates porous materials such as brick, mortar, and natural stone to stabilize the surface and reduce ongoing dusting.

This environmentally safe formula dries to a clear, matte finish without altering the natural appearance of the substrate. It also provides water resistance while maintaining breathability, helping to reduce moisture-related staining and deterioration.

Ideal for exposed interior masonry surfaces requiring dust control and light protection.
