Elastic silicon PU material is widely used in sports fields. It is an excellent sports field material. The main components include silicone and polyurethane. It is characterized by more safety and environmental protection, good extensibility, and good weather resistance. It can be widely used in different
climate environments. So what are the construction steps of the silicon PU sport court?
Elastic silicon PU sport court construction:
Foundation: First of all, the foundation needs to be smooth and free from peeling or cracks. Asphalt concrete needs to have sufficient strength and density. If it is a cement concrete base surface, it needs to be treated with a primer on the surface first. The cement base surface needs to be exposed to the sun for more than 20 days in the weather without precipitation, and wait for the moisture in the cement ground to fully evaporate. The old cement floor needs to be polished and leveled, so as to ensure that the floor is smoother and free of dust, which can greatly increase the adhesion between the silicon PU layer and the cement floor.
Construction: Careful inspection is required before construction. After processing, the elastic layer needs to be constructed. The elastic layer is a one-component material. We only need to use a thinner to adjust the appropriate construction consistency, and use a tooth scraper to coat it. On the base surface, the thickness of each coating should not exceed 2.00mm. About the time interval of each coating, it is a solid soil until the coating reaches the required thickness.
At the same time, we also need to pay attention to the leveling effect. If you cannot level the scratches, you need to add more thinner to ensure that the surface is leveled. If the temperature is relatively low, apply scraping after the water is evenly stirred. This can speed up the curing time of the material and reduce the interval time. The specific amount of water added needs to be determined according to the weather, and we need to avoid doing it under strong sunlight. construction.
The above are the steps for the construction of the elastic silicon pu stadium. You can refer to it when you are doing the construction.
