announced that Sto’s flagship liquid-applied vapor permeable air and moisture barrier, Sto Gold Coat, has been improved. Key features of the new formulation include increased opacity, extended UV exposure time, and low-temperature application.
Sto Gold Coat is a ready-mixed flexible air and moisture barrier membrane that is applied directly to vertical above grade wall sheathing and concrete masonry, and functions as a waterproof air barrier when combined with StoGuard joint and rough opening treatment. The new Gold Coat has increased opacity to better hide the sheathing and extended UV exposure, up to six months, to longer protect the building against the elements while waiting for the wall cladding to be installed. Sto Gold Coat can be used behind all claddings types and can be applied at temperatures ranging between 25F and 100F without the use of an additive, while still featuring low VOC levels.
“Sto Gold Coat allows you to use just one product for the entire project and it can be used all year long,” said Karine Galla, product manager for Sto Corp. “It has the same application techniques as the current Gold Coat, but with new and exciting features and benefits.”
Using Sto Gold Coat minimizes the risk of water damage. It is vapor permeable, minimizing the risk of condensation in walls, and is rigid and stable under air pressure loads. Installation is fast and easy with no specialized spray equipment required. It is also low VOC (< 50g/L).
