Floor Grinders & Scarifiers
Buy Floor Grinders & Scarifiers
Floor Grinders and Scarifiers are commonly bought for surface preparation work ahead of coatings, overlays, and flooring installations — removing laitance, adhesive residues, surface contaminants, and high spots to create a clean, profiled substrate. Grinders use abrasive tooling for controlled material removal and surface levelling, while Scarifiers use rotating cutters for more aggressive profiling and coating removal. Wenbro stocks both machine types to support commercial flooring, industrial, and civil surface prep applications. For complementary surface and floor preparation equipment, see our Surface and Floor Prep range, and for cutting work, our Concrete Saws cover related requirements. All machines are maintained in-house.
Frequently Asked Questions
What’s the difference between a Floor Grinder and a Scarifier?
Floor Grinders use rotating diamond or abrasive segments to progressively remove material and level surfaces — suited to smoothing high spots, removing coatings, and preparing floors for overlays. Scarifiers use multi-tipped rotating cutters for more aggressive material removal, making them better suited to thick coating removal, profiling, and anti-slip surface texturing.
What surfaces can Floor Grinders be used on?
Floor Grinders are primarily used on concrete but can also be used on stone, terrazzo, and certain resin surfaces depending on the tooling used. Diamond segments are the most common tooling for concrete, with different bond hardness suited to soft, medium, and hard concrete.
Do I need dust extraction when using a Floor Grinder or Scarifier?
Yes — both machines generate significant dust, particularly when working on concrete. Industrial vacuum extraction should be used in conjunction with the machine to contain respirable silica dust, which is a serious health hazard. Confirm dust extraction compatibility when purchasing. Call 087 073 7777 for guidance.
What prep is required before applying floor coatings or overlays?
The substrate must be clean, dry, free of contaminants, and correctly profiled to achieve adequate adhesion for coatings or overlays. Floor grinding typically achieves a CSP (concrete surface profile) of 1–3, while scarifying achieves a more aggressive profile. See our full Surface and Floor Prep range for supporting equipment.
Does Wenbro service Floor Grinders and Scarifiers after purchase?
Yes — Wenbro’s in-house workshop covers all servicing and maintenance on Floor Grinders and Scarifiers sold through us. This includes tooling advice, motor servicing, and drive system checks. Contact the team on 087 073 7777.
