AquaMast cold bituminous mastic for roof repair and waterproofing

Mastics and liquid membranes

AquaMast repair mastic is packed in small 3 kg euro pails and designed for spot work on roofs: sealing blisters, cracks, tears and holes, and partial sealing of roll and mastic coverings. It is also used to bond bituminous materials to brick, plaster, concrete, metal, timber and ceramics. The mastic has a pot life of at least 2 h, withstands heating up to +100 °C and is applied by spatula or trowel at −10…+40 °C. It is not used inside residential premises.
