MasonryDefender All-Purpose Sealer for Brick, Stone & Concrete – Transparent Waterproof Coating (1 Gallon)

Protective, Clear, and Easy to Apply

MasonryDefender All Purpose Sealer is a penetrating silane siloxane coating designed for exterior brick, stone and concrete surfaces. It forms a water repellent barrier beneath the surface while staying invisible, so the natural color and texture remain as you remember them.

The sealer works by penetrating pores to reduce water uptake and slow the effects of weather over time. The finish remains clear, so you can seal without changing your design choices or curb appeal.
