Building Silicone Sealant - For Indoor & Outdoor Use

Mästersilikon is an all-purpose, one-component sealant with an extra-long working time. The silicone cures by reacting with moisture in the air, forming an elastic joint that can accommodate movement of up to +/- 25%.

The product can be used both indoors and outdoors, as well as in wet areas, and provides good adhesion to almost all surfaces without a primer. Recommended for joints between different materials, as well as for facade elements, expansion joints, and around doors and windows.

Volume: 300 ml (10.14 fl oz)
