SURFACE PREPARATION • The surface should be free from grease, oil dead mortar / concrete etc. • Remove all loose concrete/dead mortar with gentle chipping to roughen the surface. • Clean the surface with wire brush                                                                                         Applying PU Sealant for Nut and Bolts. SuperThermoLay® is a five layered system with Atactic Polypropylene (APP) modified non-woven polyester reinforced weighing 160 g / m2 bituminous membrane (3mm) for superior waterproofing. This type of membrane shows excellent tensile strength and dimensional stability. The torch side of the membrane is covered with polyethylene film for protection of the membrane. The polymer modification of bitumen with APP results in an excellent resistance to hot and cold temperatures.SuperThermoLay® with cold flexibility up to 2°C is supplied in following variants: • Plain finish with thermo-fusible polyethylene film on both surfaces.• Apply a coat of ShaliTex Primer / ShaliTex Primer WB @ 0.3 - 0.5 L / m2 and allow it to dry till tack free • After the primer applied surface gets dried align SuperThermoLay® on the substrate by unrolling the membrane • Re-roll the roll into its original form so that alignment is not disturbed. • Point the torch towards the primed surface and then on the underside of the membrane.Torch till the compound reaches its softening points •The best visual to confirm this is when the embossing on the membrane starts to disappear. •Roll the membrane forward while firmly pressing it to the substrate so that it bonds Keep overlap margin for minimum 100 mm between two adjoining membranes for end laps and a minimum of 75 mm for side laps. • Ensure that a constant flow of bitumen is maintained across the whole width of the roll and that a bead of bitumen is extruded from all edge which demonstrates that a good seal has obtained • All angles & abutments upstands should be sealed with extra care to ensure perfect bondage. Seal the edges well into grooves & protect to seal with a polysulphide / polyurethane sealant, namely, ShaliSeal PS GG / ShaliSeal PU GG. • SuperThermoLay® applied all over the terrace must be finished with a coating of SuperSilverShield for non-trafficable area. For foot trafficable area, overlay with PCC dosed with ShaliPlast IW of 50 mm thick / tiles loosely laid or fixed
