Product Details

Everbuild Black Jack Bitumen Trowel Mastic 903

Trowel Mastic is a trowel applied black heavily filled bituminous compound with added fibres for reinforcement.

Used mainly for waterproofing, stopping, bedding, bonding, and sealing, and can adhere to a number of different substrates including mastic asphalt, roofing felt, corrugated and cast iron, fibre cement, and slates, timber, concrete, and metals such as copper, zinc, and lead.

The product forms a surface skin, but the mass below remains soft to allow for moderate movement. It is easily applied using a trowel or putty knife. For application details on different substrates please refer to the datasheet.
