Does Stormdry change the appearance of walls?

Stormdry has been formulated to be a colourless water-repellent for brick, stone and concrete. It allows porous masonry to be waterproofed whilst allowing it to retain its natural appearance and allowing it to continue to "breathe."

Although some darkening of the masonry substrate may occur after Stormdry has been applied, this will fade over time and the masonry will revert to its original appearance.

Because Stormdry achieves its water repellency by lining the pores of the masonry rather than by coating the masonry surface it will not leave the glossy sheen associated with some "masonry sealant" products.
