Confirms to ASTM C 836
Perma Elasto Shield PU is a single component VOC compliant, ready to use, liquid polyurethane based waterproofing membrane. It is composed of a blend of polyurethane and selected hydrophobic fillers, minerals, gelling agents and special stabilizers. It cures by reaction with humidity, maintains its elasticity and is suitable for use both on horizontal as well as vertical surfaces. Upon curing Perma Elasto Shield PU forms a tough and flexible membrane which is resistant to a wide range of temperatures, oxidation, radiation and Ultra Violet light.
Perma Elasto Shield PU is suitable for use in waterproofing roofs, terraces, podium, multi level car parking, terrace gardens, basements etc. It is highly useful in waterproofing wet areas such as sunk slabs of toilets and bathrooms, built up roofs, masonry and concrete walls, bridge decks, metal and plastic roofs and also repairing old roofs.
- Perma Elasto Shield PU is non toxic hence complies with green building product requirement.
- Perma Elasto Shield PU is a highly elastic product and forms a rubber like membrane which is capable of withstanding severe expansion, contraction and deck movements.
- The membrane remains crack free under severe exposures to oxidation, ozone, UV light and temperature conditions.
- The product has superior wetting and adhesion properties which ensure superior bond with any kind of substrate and helps in getting over peeling problems.
- Perma Elasto Shield PU when applied adapts to any irregular surface forming a waterproof blanket.
DIRECTIONS FOR USE
Surface to be waterproofed shall be dry, clean, sound and free of all contaminants which may interfere with adhesion or proper curing .The substrates should not contain holes or cracks and should be dust free. All shrinkage cracks shall be treated with suitable material.
Perma Elasto Shield PU is spread at the desired thickness onto the prepared surface. The coating is applied from the container using standard roofing brushes, squeegees or airless spray equipment at the recommended coverage rates on properly cleaned and prepared dry substrates. Application of the Perma Elasto Shield PU system should be done in one complete step to create a smooth uniform self leveling surface without cold joints, lines or streaks. Apply the first coat at the rate of 500 micron thickness. Let it dry fully (approximately 4-6 hours should be waited between two layers), then apply the second coat (500 micron thickness) .Waiting time shortens in hot weather and lengthens in cold weather.
- Caution:- Do not mix with water and do not apply on moist surfaces. The surface to be applied should be free of moisture.
