Foundation Armor water repellent sealers make great sealers for protecting clay roofs from premature deterioration caused by water absorption. Foundation Armor water repellent sealers penetrate through the surface of the clay where they chemically react to form a hydrophobic barrier within the pores. The surface of the clay will remain unchanged and the clay will look exactly as it did before being sealed.
