Concrete Grinding Perth

Concrete Surface Profile (CSP) is the standardised measure of how rough a prepared slab is, set by the ICRI. CSP2–CSP3 is the typical profile required for epoxy and polyaspartic floor coatings to mechanically key into the concrete and bond reliably.

Acid etching is inconsistent, can leave residue that compromises adhesion, and doesn't remove existing coatings. For professional floor systems, mechanical diamond grinding is the reliable, manufacturer-recommended method for a sound bond.

Yes. Coating and adhesive removal is one of the most common reasons people call us. We grind back old paint, failed epoxy, tile adhesive and carpet glue to clean concrete wherever the slab allows.

Yes, once it's cured enough to grind without tearing the surface. We'll advise the right timing based on the slab age and the finish required.

Grinding corrects many high spots and minor undulations and removes trip points. Major level problems, like a slab that falls the wrong way, may need patching, self-levelling compound or resurfacing, which we'll flag on inspection.

Yes. We grind with H-class HEPA vacuum extraction connected to the machines, which captures the bulk of the fine silica dust at the source, far cleaner than uncontrolled grinding.

Grinding is usually priced as part of the floor preparation for a coating or polishing job rather than on its own, because cost depends heavily on what's being removed, slab hardness, area and access. Send photos and measurements and we'll give you a clear scope and price.

A typical residential garage or room is ground and prepped in a day. Larger areas, heavy coating removal or extensive crack repairs take longer. We confirm timing when we quote so you can plan the coating or flooring that follows.

You can hire a hand grinder, but matching the correct CSP profile, keeping the slab flat, controlling silica dust and reaching the edges is where DIY jobs usually fall down, and a coating over a poorly prepped slab is what peels. For any floor you want to last, mechanical grinding with the right tooling and dust extraction is worth getting done properly.

Yes. We regularly prepare slabs for tilers, flooring installers and builders, including grinding back adhesives and correcting levels, so the next trade starts on a clean, sound, correctly profiled surface.
