What is an Acrylic basketball court?

An acrylic basketball court is a multi-layer water-based acrylic emulsion coating system applied to an asphalt or concrete base. Silica sand, rubber powder or other fillers are added to create texture, elasticity and resistance. Acrylic systems are widely used for outdoor basketball, tennis and multi-sports courts due to their color stability, UV resistance and relatively low life cycle cost.

Key Features of Acrylic Vessels

• UV and Weather Resistant: Colorful and resistant to snapping and fading of sunlight.

• Customizable Texture: Sand-filled layers allow you to customize your grip for basketball while maintaining adequate slide to reduce joint stress.

• Low VOC, water based: environmentally friendly, fast drying and easy to wash.

• Efficient Cost-Effective: Lower initial cost than most shock-absorbing polyurethane or silicon PU.

• Easy Maintenance: Simple scaling, occasional washing and re-shuffling every few years keeps the surface looking fresh.

Typical structure of an acrylic system (from bottom to top)

1. Subbase: asphalt or concrete (correct hole, level and moisture)

2. Primer/sealant (optional): enhances porosity adhesion and sealing

3. Cushion/base suits (optional): acrylic with rubber granules for absorption cushioning

4. Texture/new hair

5. Color Coats: Pigmented acrylic top guests for aesthetics and UV protection

6. Lines and Markings: High contrast acrylic line paint to basketball standards

What is PU Silicon Court (Silicon PU Sports Court Ploor)?

Silicone PU (SPU) is a hybrid multi-layer sports flooring system that combines a hard elastic top layer with an elastic cushion underneath. It is typically used on concrete substrates and provides a balance of elasticity (shock absorption) and ball response. Compared to conventional acrylic coatings, PU silicon offers greater stability and comfort, making it popular for multi-functional school and public vessels.

Key Features of Silicon PU Crafts

• Stretchy and Comfortable: Built-in cushion layer reduces impact on joints.

• Stable Ball Rebound: The hard elastic top cap provides a fast ball response suitable for basketball.

• Free, non-porous finish: easier to clean and more resistant to water penetration.

• Excellent paving performance: more tolerant of minor subgrades than rigid pavements.

• Indoor/Outdoor Use: Can be used in both environments with proper underground design.

Typical silicon structure of a PU system

1. Concrete base: with moisture barrier where necessary

2. Primer: for deep penetration and adhesion

3. Cushion elastic layer: PU based or modified elastic layer

4. Hard Elastic Top Layer: Provides ball speed and abrasion resistance

5. Top Layer Finish: UV Resistant Finish, SPU Color Finish

6. Game lines: PU or acrylic paint markings

Acrylic vs Silicon PU: Quick Comparison

Rule of thumb: Choose acrylic when you want a cost-effective, ultraviolet, textured outdoor basketball surface. Choose Silicon PU when you need extra comfort, elastic performance and better bridge connection while maintaining high ball speed.
