Drytex PU Waterproofing Chemicals

DRYTEX PU is a one - component, VOC compliant, ready to use ,elastic, polyurethanebased liquid applied waterproofing membrane. It cures by reaction with humidity, maintains its elasticity, suitable for applications to horizontal and vertical surfaces. DRYTEX PU is specially designed from a blend of polyurethane, reinforced with special water repelling fillers, minerals, stabilizers and gelling agent.
Features

• It’s a highly elastic product, cures to a seamless rubber like membrane capable of withstanding severe cases of expansion, contraction and deck movements.
• Highly resistant to oxidation, UV light and ozone because of unique additives used in compounding it. It does not crack.
• Highly resistant to abrasion, water and root penetration.
• Superior wetting and adhesion properties ensure durable bond and resistance to peeling, chipping, and or separation and a longer life
• Has the unique property of adapting itself over the irregular contours of the deck and forming a waterproof and impervious blanket
• On- Walkable ( light traffic ) and resistant to chemicals
• Resistant to salty water and chemicals
• Ultra Low VOC, LEED and Green Building Construction comply product

Application field
Ideal waterproofing system for concrete based roof, wet area (toilets, bathrooms, kitchen, balcony) as an under tiling membrane, maintenance of existing roofs, masonry and concrete walls, basements, bridges, decks, podium, flower beds, planters area, terraces, corrugated metal roof etc.
Installation
(a) Surface Preparation
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. Moving structural cracks greater than 2 mm shall be routed out and caulked with approved ORGANIX material. Detailing like horizontal-vertical junctures, projections, expansion joints and other areas of potential high movement may require reinforcement mate and sealants to detail. Consult with OBS tech for further information. All detailing must be cured for a minimum period of 12 hours prior to the application of the liquid membrane. Detailing shall be wiped clean prior to the application of the membrane.
(b) Tools or Equipment - Tools or equipment to be used for the application
Roller (Short nap roller)

• Brush (Good quality synthetic bristle brush)
• Spray (Airless Sprayer, 1gpm, 3,000 psi, .027 or .031 tip)

(c) Reinforcing the required areas (Optional)
Detailing like horizontal-vertical junctures, projections, expansion joints and other areas of potential high movement may require approved reinforcement mat and sealants to detail. Consult with OBS t for further information. All detailing must be cured for a minimum period of 12 hours prior to the application of the liquid membrane. Detailing shall be wiped clean prior to the application of the membrane.
(d) Coating Application
Before application, mix DRYTEX PU liquid well with a slow and stable speed mechanical mixer at least for 3 minutes. The mixing container should be dry and clean.This rapid setting liquid 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 DRYTEX 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 0.6 kg / sq.m Let it dry (approximately 4-6 hours should be waited between two layers), then apply the second coat at the rate of 0.6 kg /sq.m rate. Waiting time shortens in hot weather and lengthens in cold weather. Full cure for foot traffic and flood test require min curing period of 48 hours.
