Longseal 100 Application

Firstly, it is important that the surface is clean and free from dust and grit, as well as having no cavities and cracks visible. If cavities or cracks are apparent in the surface, use a mastic filler before applying the primer to smooth the surface ready for the waterproof membrane. Then, a primer can be applied to improve bonding in certain applications. Once the primer is applied, then the membrane can be administered. The membrane should then be immediately covered with a cementitious screed or similar protective layer.
