Polyurethane Waterproofing Coating is a coating that forms a film that prevents rainwater or groundwater from seeping through. It can contact with moisture in the air and then cure, forming a tough seamless integral waterproof membrane on the surface of the base. This waterproof membrane has a certain degree of extensibility, elasticity and plasticity, crack resistance, seepage resistance and weather resistance, can play a waterproof, seepage control and protection. Waterproof coating has good temperature adaptability, easy to operate, easy to repair and maintenance.
Polyurethane Waterproofing Coating features
1.Polyurethane Waterproofing Coating can be in the wet or dry on a variety of substrates direct construction.
2.strong bonding with the substrate, the polymer substances in the coating film can penetrate into the substrate within the micro-fine crevices, following a strong type.
3.the Polyurethane Waterproofing Coating film has good flexibility, strong adaptability to grass-roots expansion or cracking, high tensile strength.
4.Green environmental protection, non-toxic and odourless, no pollution of the environment, no harm to the person.
5.Good weather resistance, high temperature does not flow, low temperature does not crack, excellent anti-aging properties, can resist oil, abrasion, ozone, acid and alkali erosion.

 Features：

1)Simple application, no joints: roller, airless spray, brush.

2)High solid content and excellent resistance to weather aging.

3)Full surface adhesion.

4)It forms a complete and seamless membrane without any joints after the coating curing.

5)Excellent heat and cold resistance.

6)Non-toxic, no abnormal odor.

7)Many colors are available and the colors also can be customized.

8)It is especially suitable for waterproof construction where the shape is complex and pipeline bend place.

Construction Note：

Clean up before construction, can be rinsed with water once, keep the paste place base surface clean, no greasy dirt no moss, no loose layer. Roof cement surface sand, colour steel tile rust, base surface strength is not high, need to use sealer and then paint. Choose the sunny day above 0 degree Celsius can be constructed, do not bring water to paint. Black polyurethane vinegar is brown colour when it is not dry, and pure black colour when it is dry.
