A premium waterseal designed to repel water from exterior masonry work which allows walls to breathe, reducing the risk of damage caused by water and frost. Used as a masonry water-proofer suitable for use on brick, stone and concrete. It protects against water and frost, providing a breathable coating which does not change the physical appearance of a building. A secondary benefit of the product is to repel water-borne dirt and resist fungal growth as well as help reducing heating costs, as energy is not wasted in drying out wet walls. Offers years of protection.
