The PU of the plastic basketball court is cracked. What's the matter?

First, there are only three cracking problems:

1, investigation of sub-foundation problems: whether the sub-foundation is cracked, bulging, etc!

2. Material problem: materials should be conventional materials, not too many other things!

3. Construction technology is not in place: pu material has requirements for foundation, such as humidity, weather and temperature.

Second, use a mill to grind off all the places that fall off or blister, and clean them very clean. Not cleaning them will directly affect the quality of the surface layer.

After foundation treatment, scrape a layer of interface agent to form a closed layer. Then the elastic layer is scraped. Generally, each layer is 2MM thick. After completely drying, apply the next layer. Until the thickness required by the customer is scraped.

Finally, the topcoat is scraped, and the materials are absolutely environmentally friendly. It depends on whether the technology of the selected construction unit is excellent! Generally, this problem will not appear on the stadium built by Qiuxin Company!

Third, the pu material itself is elastic. Except that it is not handled well, there will be no problems due to the weather. Its service life exceeds 10 years!

Fourth, the new cement base should be completely dried and dried for a few days before construction!
