Used to obtain waterproofing on:
Surface on which application shall be carried out must be cleaned of any dust, dirt, rust and grease and any loose parts scraped.
If the surface to be insulated is concrete, then it must have been finished with sloping grout burnished using a wooden trowel and be clean and dry. Before the application of the membrane, the surface must have been spread with bituminous solution undercoat BITUSOL (TS 103) or bituminous emulsion undercoat BITUMER (TS 113) and allowed to dry up. Membranes start to be applied in a direction perpendicular to the slope at the lowest part of the roof (lowest elevation). The membrane is heated up with oxyacetylene burner flame and then adhered to the surface. The rows must must be laid with some shift sideways. Membranes must be overlapped 15cm on the short sides and 10cm on the long ones, and the seams must be well adhered. Between the layers, there must be a shift sideways for 50cm on the short side and 5m on the long one.
Botanik PE4 is launched into the market in rolls 1m wide and 10m long.
The membrane rolls should be stored vertically under a roof, protected from direct sunlight. If the rolls have to be stored outdoors for a long period of time, they must be covered with a protective layer in order to protect them from the sunlight.The membrane rolls or pallets should not be stacked on each other.
