What is Bitumen Trowel Mastic?

Bitumen trowel mastic is a black, heavily filled bituminous compound reinforced with fibres. In spite of the product’s surface membrane, it remains soft below to allow moderate movement. Can be used as a sealant or a filler for mastic asphalt, roofing felt, corrugated iron, metal gutters, and downpipes.

Applying Trowel Mastic

Before using Trowel Mastic, make sure that all surfaces are be clean, dry, and free from dirt, dust, grease, and other contamination. To apply it, use a trowel or a troweling knife. The surface should be pointed to a smooth finish immediately after application. Surface drying occurs within 7 days, followed by gradual drying of the cross-section. After use, flatten the surface of the mastic and replace the polythene disc, ensuring the container is properly sealed.

After using the trowel, make sure that you clean tools and equipment immediately after use with white spirit. Hardened material can only be removed by mechanical means. Do not use solvents to remove from hands/skin – use soap and water with the aid of Wonder Wipes.
