How to Seal Cultured Stone Masonry

Cultured stone, like other masonry finish materials, is susceptible to damage caused by moisture and weather. One of the most common outcomes related to these conditions is white staining, or efflorescence, on the surface of masonry materials. One of the most widely used preventative actions for this condition involves the generally straightforward task of applying masonry sealer to the masonry surface. Masonry sealer is very effective in protecting the aesthetics and integrity of materials like cultured stone.
