Silicon PU Court

PU Basketball Court Product Data Sheet

Product Introduction
PU Basketball Court is a professional elastic synthetic sports surface system constructed through multi-layer application processes including primer, elastic layer, reinforcement layer, and topcoat, primarily composed of polyurethane materials . The product features a hard-top elastic-bottom structure design: the hard surface ensures ball rebound rate exceeding 90%, while the elastic layer effectively absorbs impact force to reduce sports injuries, providing athletes with professional sports texture and safety protection . PU basketball courts can be installed on cement concrete or asphalt substrates, suitable for various indoor and outdoor basketball venues .

Performance Characteristics
Hard-Top Elastic-Bottom Structure: Hard surface ensures sufficient ball rebound support, elastic layer provides cushioning and shock absorption, effectively solving ball trapping and sticking problems on soft surfaces, ensuring ball rebound rate above 90% 
Shock Absorption Protection: Elastic system specifically designed for sports provides effective cushioning absorption and shock protection, effectively reducing sports injuries caused by reaction forces on ankles, joints, and ligaments 
Slip-Resistant Starting Performance: Reasonably designed hard rough surface layer with moderate friction provides sufficient traction for starting, direction changes, jumping, and sudden stops during sports, effectively solving slip problems caused by surface wetness 
Uniform Rebound Characteristics: Innovative hard-top elastic-bottom structure, combined with rebound properties of elastic and reinforcement layers, ensures uniform and stable ball rebound, meeting professional sports requirements for ball feel 
Excellent Physical Properties: Tensile strength and elongation at break can reach over 5 times the requirements of new national standards, with good shock absorption and resilience, high comfort 
Superior Weather Resistance: Excellent weather resistance, wear resistance, water resistance, and UV resistance, adaptable to different climatic environments, maintaining color without cracking during long-term use 
Safe and Environmentally Friendly: Solvent-free eco-system, no addition or use of toxic or harmful substances, low odor, VOC indicators meet national standards, environmental parameters superior to national requirements 
Rich and Aesthetic Colors: Uniform surface texture, consistent friction coefficient, stable colors with texture, multiple color options including red, green, blue, etc. 
Long Service Life: Service life of over 10 years under normal usage conditions 
Easy Maintenance: Dense surface, dust-proof and easy to clean, low daily maintenance costs, easy maintenance and repair

Technical Specifications

Structural type

Construction process

Base Preparation
Base Requirements: Cement concrete or asphalt base must be solid, level, dry, free from oil and cracks. Cement base requires properly cut expansion joints; asphalt base should have no loose particles 
Base Moisture Content: ≤8%
Cleaning: Thorough sweeping, grinding, and vacuuming

Primer Application
Primer Application: Apply specialized primer evenly with roller until base surface forms a glossy film 
Curing Time: Asphalt base primer cures approx. 12 hours, cement base primer cures 1-2 hours

Elastic Layer Construction
Material Preparation: Mix elastic layer material (single or two-component) according to specified ratio 
Application: Apply with notched trowel, each layer thickness ≤2.0mm 
Interval Time: Allow previous layer to fully cure before next application (approx. 10-24 hours depending on weather) 
Thickness Control: Apply until required thickness is achieved (elastic layer + reinforcement layer) 
Flatness Test: After curing, test surface flatness with water accumulation method; repair uneven areas

Reinforcement Layer Construction
Application Method: Same as elastic layer; for thin layers, apply multiple coats with smooth trowel 
Surface Treatment: Ensure smooth surface; repair any irregularities or debris

Topcoat Application
Material Ratio: Two-component water-based material must be thoroughly mixed according to specified ratio (e.g., A:B=9:1) 
Dilution: Add water to achieve appropriate application consistency (typically 50-80%) 
Application Method: Apply with roller or specialized spray gun in multiple coats over reinforcement layer 
Texture Treatment: Add specialized sand for rough surface finish if required 
Recommended Practice: Basketball courts apply three coats: first two with 15% sand, third without sand

Line Marking
Dimension Positioning: Measure and position according to standard basketball court dimensions (28m length, 15m width) 
Masking Tape: Apply masking tape along both sides of boundary lines
Line Paint Application: Mix two-component line paint according to specified ratio, apply in two coats 
Remove Tape: Remove masking tape after surface dries

Precautions
Application Temperature: ≥10°C, ≤34°C; do not apply when temperature >34°C or <5°C 
Humidity Requirements: <85%; avoid application when rain may occur within 4 hours 
Curing Period: Allow at least 5 days after installation before use 
Ventilation: Indoor venues must ensure good ventilation 
Accurate Mixing: Materials must be accurately weighed and thoroughly mixed 
Leftover Materials: Seal properly; opened products should not be stored for more than 8 hours
