Yes, you can. The product is designed for impregnating clinker brick and tile, as well as natural and artificial stone surfaces. However, make sure if all components are equally absorbing.Perform a test, before use, to make sure as to the amount of product to be applied and what tool (brush or roller) or spraying equipment to use. Gloss effect may occur locally where the coat is too thick. When applied properly, the impregnating agent does not change colour of the surface being treated.
