ALLCOAT Bitumen Roof Repair elastomeric membrane is a liquid applied coating based on thick bitumen based weatherproofer, which cures by reaction with atmospheric moisture to give a continuous film that is rubbery and elastic.
ALLCOAT Bitumen Roof Repair is a very high solid coating designed to give a high build film. ALLCOAT Roof Repair has a higher viscosity than a conventional paint and can be brush applied but should not be diluted.
ALLCOAT Bitumen Roof Repair cures to a permanently flexible seamless membrane that, by virtue of its chemical reactivity in the wet state, has good adhesion to a wide range of substrates. Unlike more traditional bitumen based products, ALLCOAT Bitumen Roof Repair does not readily embrittle with age, exposure to ultra violet radiation or weathering, and hence it does not crack or craze.
Since it is elastomeric, ALLCOAT Bitumen Roof Repair is not adversely affected by extremes of temperature – consequently it does not crack at low temperatures or suffer thermal flow at elevated temperatures.
The elastomeric membranes are designed to bond to many types of substrate particularly those commonly used as roofing, such as felt, asphalt, slate, tiles, asbestos, concrete, brick, wood, glass and metals. It is essential that the substrate and structures are properly prepared and stable.
Substrates with poor adhesion to the underlying structure (e.g. blistered roofing felt) may also cause problems in providing sound over coating.
