Finally - the perfect waterproofing is available! Apply Drythane and create the green roof of your dreams...
Solvent Free, Durable, Thick Film (2.00mm) Polyurethane Waterproofing Membrane
Drythane is a solvent free, 2K Polyurethane Coating system that is non-flammable and does not emit obnoxious smells. It has been designed specifically as a high-performance waterproofing. Drythane provides lifelong protection to concrete and other masonry. Once coated, the surface is completely impervious to water. You can make green roofs with lawns, water fountains, swimming pools etc. This durable product has a design life of 20 years and more.
Seamless Membrane, Roller Applied
Liquid polyurethane applied to a thickness of 2.00 mm. The two components are mixed together, poured on the surface and spread using paint roller in two coats. Special solvent free, 2K Damp Tolerant Polyurethane Primer will seal the concrete surface before application of Drythane main coat. Can be applied even in high humidity.
Unaffected by Water
Drythane is totally unaffected by water immersion. Saturation weight gain is < 0.60% as per Procedure 7.4 (Long Term Immersion) of ASTM D 570. This unmatched property makes it ideal for use on rooftop gardens, water ponds, water tanks, pools etc.
Tough, Strong Film
Drythane is a very tough film with a tensile strength of > 2,900 Psi and hardness of 65 Shore D! It does not require any reinforcement or protection covering with concrete or tiles thereby saving a lot of cost. Covering can be used for aesthetic purposes if desired. Drythane will not degrade due to sunlight (UV), rain or heat.
Elastic, Can Span Cracks
Drythane is an elastomer with elongation of over 50%. Temperature cycling and creation of new hairline cracks in the concrete substrate will not lead to cracking of the coating. It will span the crack and continue to seal.
Drythane bonds so strongly to the substrate that in Ãƒ¢Ã‚€Ã‚œpull offÃƒ¢Ã‚€Ã‚ tests, the concrete breaks but the coating does not disbond. Products with low bond will peel and liquid water will intrude under the film and seep into the concrete.
Optional Heat Reflective Top Coat
After installing Drythane you can cover the coating with drainboard, non-woven fabric, soil and plant a lawn. This will provide thermal insulation to the roof and keep indoors cool. If you do not wish to install these and yet have a reduction in indoor temperatures, you can apply optional Drythane heat reflective top coat over the main coat.
