What is the longevity of Gemite wall coatings and sealers?
A. The longevity of Tuff-Flex, Tuff-Cote and Rain-Shield Stain WB is in excess of 25 years, and we have many projects lasting even longer. The penetrating wall sealers, such as Rain-Shield SX / SL, Rain-Shield SX WB last for about 6-7 years. Then they need to be reapplied to maintain the damproofing effectiveness.
