Trowel Mastic 5ltr
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.
A typical coverage rate for a 2mm thickness of material is 2Lt/m2. Therfore 5ltrs will cover 10m2 at 2mm thick.
Drying time depends on weather conditions and film thickness. Heavy applications will result in extended drying times.
