3mm Silicone PU court construction steps:
Step 1, concrete foundation: first check the flatness, ground strength and water content of the foundation; if the ground does not meet the construction standards, first grind the foundation surface layer and apply the single-component waterproof primer. The next step should be constructed within 2 days after rolling. If it exceeds 2 days, test it before construction. Roll the waterproof primer according to the construction area of the day. It is strictly forbidden to roll the entire venue at one time.
Asphalt foundation: fill the emulsion (0.2 kg/
m²), quartz sand and cement at 1:2:2 for bottom sealing.
Step 2, scrape the water-resistant silicone PU 3.6kg/
m², check the flatness and make appropriate repairs. (The amount of water added is 1‰-5‰ according to the on-site temperature. The higher the temperature, the less water is added).
Step 3, roll the topcoat twice, the topcoat dosage is 0.2kg/
m², 20kg topcoat is matched with 2-3kg quartz sand (150 mesh). If it is a three-second area of the basketball court, it is recommended to apply the topcoat three times (pay attention to the addition of curing agent and water).
Step 4: Site positioning and marking.
Notes:
1. The materials must be fully stirred after adding water.
2. To prevent bubbling, construction should be avoided during high temperature periods as much as possible, and the specific adjustment should be made according to the site temperature.
3. The amount of water added must be fine-tuned according to the site temperature and combined with small sample blocks.
4. If powdering occurs, it must be polished to strengthen the bonding strength of each layer.
Product Introduction
The performance of hard top and elastic bottom is a professional structure designed for healthy sports. One of the important purposes of the construction of the stadium is to provide professional, safe and healthy sports competition conditions for sports. A venue with hard characteristics can bring professional sports texture; and a sports ground with elasticity can effectively increase sports buffering and reduce the damage to athletes' ankles, joints and ligaments caused by the reaction force of the ground; at the same time, it can effectively reduce sports accidents caused by falls and falls during sports. A professional sports structure that is hard and elastic, elastic but not soft.
Practical performance
Excellent weather resistance
Silicon PU will not fade, harden, or soften due to changes in outdoor high and low temperature climates. It can maintain its bright colors for a long time even in strong ultraviolet rays, ozone, rain, and high temperature differences.
Super wear resistance
The water-based surface layer of silicon PU can ensure that the appearance and structural characteristics remain stable for a long time, and the wear resistance meets the needs of long-term high frequency of use.
Excellent anti-fouling
The surface layer of silicon PU is tough and dense, and is not easily scratched by soles or other hard objects. The court can be kept clean for a long time by simple washing
Scope of application
Senior primary and secondary schools, colleges and universities tennis courts, basketball courts, badminton courts, volleyball courts, sports fields, professional sports venues, training grounds, kindergarten playgrounds, gyms, dance studios, etc.
