SPU Overstrength Elastic Waterproofing Coating
Product Introduction:



SPU Overstrength Elastic Waterproofing Coating(Hereinafter Referred to as "SPU ") is developed and produced by latest technology introduced by Joaboa from broad.



It is one-component water solidified polyurethane waterproofing coating, composed of main ingredients like isocyanates, polyethers, with some additives. It is flexible waterproof coating by chemical reaction.



During construction, get the coating mixed uniformly, then brush it on the base directly. If necessary, added no more than 10% clean water(in terms of weight) into the coatings and blend them well by motor stirrer before coating the base.







Product Feature:



One component waterproofing coating. Easy to handle and apply.
Physical properties of the solidified film is featured with high-strength, high elongation, high-resilience, good anti fatigue and high aging resistance
Excellent weatherability, so that be adaptable to climate changes in regions with hot or cold weather.
As environment-friendly products, it contains no solvent and less volatile organic compounds(VOC), innoxious,odourless, pollution-free and safe.
By water solidified mechanism, it can form into film on moist base, which contributes to more applicable of SPU.




Points for Attention:

Substrate should be dry.
Change the brushing direction alternately at per brushing layer. Make sure the overlap width reaches 30~50mm between sequential two brushing in the same coating film.
Avoid the overlap been damaged, and its width should be more than 100mm. Clean its surface before the next brush.
Brush several times in the last application area.
Avoid stir too much SPU with water at one time, or the coating may solidified before using up.
The coating should be used up after exposed to the outside unless stored in sealed container.
Wear some protective clothing while application. Keep skin and eyes away from the coating.


Construction Requirement:

Keep the waterproofing base firm, smooth, clean, no dust, oil and visual water.
Brush directly after stirring SPU evenly.
Brush in large area: Brush SPU on the substrate with rubber scrapper, and guarantee suitable strength, uniformity and no stack.
Recommended thickness is not beyond 0.7mm at per coating film, and two or three times coating film is better.
Do the second time’s brush after the first film is dry, namely non-stick with hand. Remember the brushing direction is orthogonal with the last film, until reaches the design thickness.
If necessary, add some water whose weight is about 5-10% of the coating, and stir evenly not less than 3min by electric mixer


Application Scope:

Widely used in general buildings’ roofs, external walls, basements, balconies, kitchens and lavatories
Some special buildings like granaries, civil air defence works, bridge projects.


Package Specification:

25kg per pail or customized.
