Application instructions

Substrate preparation

Suitable substrates are concrete, masonry, metal, plastics (except PVC) and dry, non-resinous wood. The substrate must be dry, free of dust, silicone or grease, and resistant to abrasion. Loose components must be removed beforehand. Slightly soiled and porous substrates must be coated with bituminous primer (solvent-based or solvent-free) beforehand. Ensure the primer is completely dry before applying the membrane.

Application

The membrane is laid along the slope. First, peel off the protective film on a narrow strip of approx. 10 cm and carefully lay it on the roof and align it. Then unroll the membrane evenly and lay it down carefully, making sure no air pockets form. The overlap area must be 10 cm. In the overlap area especially, the membrane should be rolled firmly to achieve optimum adhesion.

Storage

Protect from direct sunlight and store at 10 °C to 30 °C. Store rolls dry and upright. The product is not susceptible to frost. Properties remain unchanged for a long time; application within 12 months is recommended.
