SuperThermoLay APP PL / MTAPP Modified WP Membrane with Spun Bonded Polyester Reinforcement

Description

SuperThermoLay APP PL is uniquely formulated pre-fabricated plastomeric waterproofing membranewith spun bonded polyester mat as a core. SuperThermoLay APP PL has an excellent resistance toweather and ageing. The core of 160 Grms non woven polyester mat offers an excellent tensilestrength, elongation and a superior lap joint strength. The polymer modification of bitumen with AtacticPolypropylene (APP) results an excellent resistance to hot and cold temperatures.

Use of SuperThermoLay APP PL forms an impervious, flexible waterproofing layer which canwithstand normal movement of structure without showing any deteoriation and serve for a prolongedperiod of time.

SuperThermoLay APP MT is coated with mineral / natural gray slate on one side with other sideremaining covered with thermo-fusible polyethylene film.

SuperThermoLay APP PL / MT is normally used in protected roofing and waterproofing applicationsin a single layer system and is also recommended as base layer in multilayer system in variousapplications, Including damp-proofing.

Application Methodology

Clean the surface thoroughly to make it smooth and free of any foreign material.

Apply a coat ofShaliTex Primer @ 0.3 Ltrs per sqm and allow it to dry. In areas of high humidity,the prime surface should be left over-night.

On the primed surface, start laying of membrane at lowest point of the slope roof and progress tothe higher point. Unroll the membrane half-way, align the side laps and fix SuperThermoLayAPP PL / MT membranes by using a LPG torch and applying uniform pressure with a roller/wetcloth to ensure to remove entrapped air, if any. Instead of propane torch, you may applyShaliPrime APP, if so desired and wherever torching is not permitted or not advisable. IfShaliPrime APP is applied, ShaliTex Primer need not be applied.

Flame should be moved in shape of L applying about 75 percent of the heat to the roll and 25percent to the substrate including the lap area of previously installed membrane. The flameshould be moved across the width and upto the lap edge while membrane is slowly unrolled andadhered to the under lying surface.

Heat both layers of membrane at the overlap and use round tipped hot trowel to seal overlap.Excess compound should be smoothened and pressed into seam using hot trowel. Overlap joint

shall be provided of 75mm in longitudinal direction and 100mm in transverse direction SuperThermoLay APP PL waterproofing membrane shall be finally coated with Super Silver

Shield for non trafficable roof. For trafficable roof SuperThermoLay APP PL Waterproofingsystem shall be protected with PCC of 50mm thick/tiles loosely laid or fixed

Health & Safety

Use goggles, hand gloves, gum boots and nose mask during application.

Clean hands with warm water after application.

Packing

Rolls are available in 1 Mtr x 10 Mtr in 3 and 4 mm thickness.SuperThermoLay APP PL is alsoavailable in 2 mm.

Storage

Keep in cool and dry place under shed away from heat.
