I. Application of Polyurethane Sealant:

II. Process for applying APP modified membrane:
 Clean the surface thoroughly to make it smooth and free of any foreign material.
 Apply one coat of ShaliTex Primer @ 0.3 L per sqm and allow it to dry.
 In areas of high humidity, the primed surface should be left over-night.
 On the primed surface, start laying the membrane unrolling it as work progresses. Align the side laps and fix SuperThermoLay APP PL / MT
membranes by using an LPG torch and applying uniform pressure with a roller/wet cloth to ensure the removal of entrapped air, if any.
 The flame should be moved in the shape of “L” applying about 75 percent of the heat to the roll and 25 percent to the substrate including
the lap area of the previously installed membrane.
 The flame should be moved across the width and up to the lap edge while the membrane is slowly unrolled and adhered to the underlying
surface.
 Heat both layers of the membrane at the overlap and use a round-tipped hot trowel to seal overlap.
 The excess compound should be smoothened and pressed into seam using the hot trowel.
 Overlap joint shall be provided of 100 mm in a longitudinal direction and 150 mm in a transverse direction.
 Protect the membrane with a plaster of 15mm / an overcoat of aluminium-based protection coating.
