Field of application
Designed for the safe and permanent outside waterproofing of basement walls, foundations, floor plates etc. Since applications of waterproofings are carried out depending on the water-loading conditions, the loading conditions have to be determined exactly by the planner prior to the application.

Bituminous Sprayed material has been successfully used in load conditions of pressurised water for many years (Consumption min. 6 kg / m²). The coating is also suited for the intermediate waterproofing underneath screeds and for bonding insulation- and drainage- boards.

Substrate preparation
The substrate should be dry or slightly damp, frost-free, free of tar and oil and free of loose particles. Remove protruding mortar residues, break edges; corners and transitions should be rounded out by installing fillets. Mineral substrates always have to be primed by spray application. On polystyrene substrates, priming is not necessary. Defects / cavities which are deeper than 5 mm, like for example mortar pockets or open butt- and horizontal-joints, must be closed level beforehand with repair mortar. Prior to the application of the waterproofing layer, the scraped layer must have dried far enough so that it is not damaged by the subsequent application of the main waterproofing layer.

Fillets (leg length: 4 – 6 cm) in the wall / floor junction must be applied at least 24 hours prior to the beginning of the application of the waterproofing using a repair mortar (Consumption per m: approx. 2 – 3 kg). The subsequently applied area waterproofing can in both cases be applied only after full cure of the fillet.
