This 3kg red trowel-applied mastic is designed for perimeter pointing around both timber and metal window and doorframes. The oil-based formulation enables it to form a weather-resistant seal for jointing applications where flexibility and adhesion are important.
Commonly used for bedding new frames into masonry or re-pointing existing brickwork, this mastic is worked into place with a trowel to ensure a consistent seal. Its plasticised composition supports good workability and provides a suitable solution for a wide range of on-site joint sealing tasks involving window and door installations.
