Common Usage

Phylon WB is a non-yellowing, water-based, acrylic coating that highlights the natural color of masonry by providing a clear, gloss sheen. Its special formulation provides a hard, durable gloss finish. The treatment does not alter the natural texture of the surface, nor significantly affect the vapor transmission qualities of the substrate. Phylon WB provides a durable, wet-look finish to exposed aggregate, ground-face block, sandblasted concrete and many other vertical concrete, masonry and natural stone surfaces.


Semi-transparent white when applied. Dries to a clear, gloss finish.
