BLOCKSEAL is a cementitious membrane that provides more waterproof protection than paint-type coatings. After application, the material will dry in 3-4 hours and will set up in 24 hours to form a hard, waterproof protective coating that essentially becomes an integral part of the concrete or masonry surface.
BLOCKSEAL can be used anywhere a waterproof masonry coating is required or desired. It is especially effective on masonry walls where it is applied, either as a ﬁnish waterprooﬁng coat or mixed with clean washed sand as a heavy coat to conceal mortar joints and to bring wall surfaces to true.
BLOCKSEAL can also be used to eliminate the very time consuming and expensive method of rubbing concrete surfaces to obtain smooth and homogeneous surfaces.
