Everbuild 103 Trowel Mastic is an oil-based compound supplied in a 6kg pack, designed for perimeter pointing around wood and metal window or door frames. Applied using a trowel, it helps form a weather-tight seal for both new installations and maintenance work.
This red mastic can also be used for re-pointing brickwork or bedding frames into masonry surrounds on site. With added plasticiser to improve adhesion and flexibility, it helps reduce the risk of cracking over time, making it suitable for a range of external weatherproofing and sealing tasks.
