Features and benefits

Bostik All Weather Trowel Bituminous Mastic is a multi-purpose trowel applied bituminous compound for waterproofing, stopping, bedding, pointing and sealing. It contains fibres for reinforcement and will seal and fill holes and cracks in mastic asphalt, roofing felt, corrugated iron, cast iron, fibre cement, slates, lead, copper, zinc, concrete and timber. It has excellent cohesive strength and adheres to most roofing substrates. Bostik All Weather Trowel Bituminous Mastic dries to a flexible black material, which remains soft and pliable for a long time after application. This allows the product to flex with changes in temperatures.

  • For bedding, pointing, sealing & filling cracks
  • Use on roof felt, asphalt, corrugated iron and metal guttering & downpipes
  • Contains fibres for reinforcement
