Quick Answer

Acrylic sports court coating — the textured, 0.3-1.5 mm colored acrylic/latex system on basketball, tennis and pickleball courts — is removed fastest with PCD tooling on a walk-behind grinder. A 250-500 mm grinder with PCD trapezoid discs or a PCD plate strips 100-200 m² per hour in one pass at 300-500 RPM. Angle-grinder PCD cup wheels handle edges, corner cuts and fence-line areas. Finish with a 30/40 metal-bond diamond pass to clean residue before recoating. Do not use scarifiers — they leave gouges in the slab.

Why PCD, Not Diamond, for Acrylic Courts

Standard diamond cup wheels glaze instantly on acrylic and rubberized coatings. PCD (polycrystalline diamond) has a sharp, fracture-resistant edge that shaves the organic coating off the slab instead of trying to grind it. On a walk-behind grinder:

• PCD trapezoid discs on a 3-head planetary grinder: one pass strips the textured top coat and color layers.
• PCD plates / pucks on single-disc machines: same result, slightly slower.
• Metal-bond diamond after PCD: 30/40 grit cleans the thin residue film left behind and opens the concrete for the new coating.

Tooling Setup by Machine

Machine	PCD tooling	Throughput
250 mm single-disc	10 inch EDCO PCD Diamond Plate for Floor Preparation (JOY-ED-PCD1) PCD plate	60-100 m²/h
500-650 mm planetary	3-6 PCD trapezoids per head	150-250 m²/h
Angle grinder 125 mm	Diamond PCD Cup Wheels with 6 PCD for Floor Preparation (JOY-CW-PCD6) PCD cup wheel	Edges, fences, corners
Husqvarna-style grinder	Husqvarna Piranha PCD Tool for Concrete Floor Coating Removing (JOY-HQ-PCD2) Piranha PCD tool	Per existing holder

For a standard 250 m² outdoor court, a 500 mm planetary with PCD trapezoids finishes strip-down in 2-3 hours plus edge work.

Step-by-Step Court Strip

• Inspect the slab: note cracks, spalling and joint fill. PCD will expose them — plan repairs before recoating.
• Dry strip first: run the grinder flat, no water. Wet PCD loads with paste.
• One pass only: if coating remains, slow the traverse rather than going over twice — double passes cut the concrete.
• Edges: switch to the PCD cup wheel for 150 mm around fence lines and net posts.
• Cleanup pass: 30/40 metal-bond diamond at the same machine speed, one light pass, removes the 50-100 micron residue film.
• Vacuum and inspect: you should see clean gray concrete, no color stain, uniform CSP 2-3 profile for the new acrylic coat.

Pitfalls That Ruin the Job

• Scarifier or flail use: leaves 1-2 mm deep gouges that telegraph through the new coating. Use PCD only.
• Too much downward pressure: PCD cuts fast on its own weight; pressing harder fractures PCD tips.
• Skipping the diamond cleanup pass: residue film makes the new coating delaminate within one season.
• Working in direct sun: acrylic softens and smears; grind early morning or evening in summer.

Frequently Asked Questions

Q: Can I remove acrylic court coating with a diamond cup wheel?

A: Not efficiently. Standard diamond glazes on organic coatings and takes 10x longer. PCD is the right tool for 0.3-1.5 mm acrylic systems.

Q: How thick is sports court coating, and will PCD cut through rubber infill?

A: Acrylic courts run 0.3-1.5 mm. Synthetic turf infill is a different job — PCD will cut it but clumps and must be stripped mechanically first.

Q: Do I need to remove court line paint too?

A: Yes — line paint is part of the coating system and comes off in the same PCD pass. If old lines resist, slow the grinder traverse; do not increase pressure.

Q: What profile does the new acrylic coating need?

A: CSP 2-3, achieved by the 30/40 diamond cleanup pass after PCD. Most acrylic court manufacturers specify a clean, slightly textured slab.

Conclusion

Sports court resurfacing is a recurring seasonal contract: every 4-8 years old courts need strip-down and recoat. PCD trapezoids and PCD cup wheels cut the strip time in half vs old scarifier methods, and the slab comes out ready for new color. JOY TECH supplies PCD tooling for Husqvarna, EDCO, Lavina, Scanmaskin and most common grinder holders, plus PCD cup wheels for edge work — spec the right PCD set before the court resurfacing season starts.
