For increasing friction on the surface of PVC sports flooring for badminton courts, you'll want to consider textures that provide good grip and traction without causing excessive resistance or hindrance to movement. Here are a few texture options to consider:

Embossed Surface: An embossed surface features raised patterns or textures that create friction and improve grip for players. Look for patterns designed specifically to enhance traction without causing discomfort during play.

Gravel texture: Farfly's Gravel Texture is a technology that enables the surface to appear undulating and grainy.

This creates a slightly gritty texture that offers excellent traction for quick lateral movements common in badminton.

When selecting a texture for PVC sports flooring for badminton courts, it's essential to consider factors such as player comfort, performance, and maintenance requirements.
