Factory single component water based polyurethane pu waterproof roofing coating Introductionwater based polyurethane waterproof coating is single component emulsion polymer waterproof coating ,its basal component is polyurethane emulsion. And the greatest advantage is friendly to environment.Features 1.Water based , single component ,colorful ,non-toxic ,tasteless and environment friendly .2.High tensile strength and elasticity.3.Resistance to aging , UV and corrosion.4.Easy to apply and long useful life.Application 1.It is used for sloping roof ,wall surface and especially various irregular roof.
2.Basement ,kitchen ,wash room ,reservoir ,swimming pool and decorative roof requirement.
3.Cement board ,asbestos product , ceramic ,floor tile ,wood floor ,air-raid shelter ,color steel tile ,
4.tunnel ,subway ,concrete floor ,pipe and so on.Construction 1.Substrate should be clean , flat and free from grease oil , dust or laitance . you can brush a little water to keep surface moist ,easy to construction ,and moisture content should less than 5%.
2.Brush directly after stirring the material evenly .(If the waterproof coating is too dense , you can add water. )3. The waterproof coating need to brush 3-4 layers ,and recommend that the thickness should be not beyond 0.7mm at per coating film. 1.0mm ≤the total thickness ≤2.0mm, the regular thickness is 1.5mm .After the first layer is curing ,(interval time : 4h-8h)do the second layer ,And the second should be at right angle to the first layer.4.If necessary,do the protection layer after the coating is better
