Usage

Apply with a standard sealant gun to clean, dry, and dust-free surfaces. The product cures by reacting with moisture in the air, forming a permanently elastic and weather-resistant seal. For porous or alkaline surfaces such as concrete or brick, the use of a primer is recommended for optimal adhesion. Suitable for sealing connection and expansion joints in façades, walls, partitions, and for glazing applications, including laminated glass.
