360 Cromar 5L Bituminous Trowel Mastic Black
Trowel Mastic is a heavily bodied bituminous mastic that is used for filling joints, cracks and splits in roofing and building materials including roofing felt, asphalt, concrete, asbestos cement and metallic guttering and drainpipes. It is resistant to water penetration immediately after application and is ideally suited for maintenance and remedial work

Ensure that the surface is clean, dry and free from oil, grease, dirt and organic growth. Organic growth such as moss and lichen can be removed using Fungicidal Wash. Bolt heads on roof sheets should be wired brushed to remove rust before being sealed with Trowel Mastic. Porous surfaces should be primed with Bituminous Primer in order to seal the surface and allowed to dry thoroughly.

Apply Trowel Mastic by trowel or putty knife, forcing material into cracks and joints and smoothing out on either side. Cracks or joints of more than 3mm should be reinforced with glass fibre scrim and covered with a second application of mastic.

The typical coverage rate for a 2mm thickness of material is 2L/m².
