TECHNOELAST K-PS 170/5000
TECHNOELAST K-PS 170/5000 is a polyester reinforced, slate covered Torch – On Cap sheet, saturated and coated with highest quality SBS (Styrene-Butadiene-Styrene) modified bitumen. This product can be applied to suitable Torch - On underlays as top layer in built up waterproofing systems. Not recommended for use as single ply waterproofing.
TECHNOELAST K-PS 170/5000 membranes are applied by traditional Torch – On methods onto previously installed base layer/underlay, clear of any debris or sharp projections, primers shall be used to prepare substrate for achieving most effective waterproofing longevity. The membranes should be heated carefully ensuring the complete melt of dispersible film as work proceeds and maintaining 5 mm bead extrusion from all laps. Side laps must follow the manufactured mineral free pilot selvedge with end laps at minimum of 100 mm. The cap sheet should be offset 300 mm from the underlay to avoid side build up.
