Everbuild 103 Trowel Mastic 6kg

6kg 103 Trowel Mastic is an oil-based adhesive mastic that can be applied with a trowel and is ideal for the perimeter pointing of wood and metal window and door frames. The 103 Trowel Mastic creates a weather-tight seal, and the use of a plasticiser improves its adhesive properties while lowering the chance of cracking.
