Grinding & Surface Prep
Diamond grinding, shot blasting, and scarifying for the profile your coating demands
Surface Profile Matters
The bond between a coating and concrete is only as good as the surface preparation. Inadequate prep is the leading cause of coating failures—delamination, peeling, and premature wear all trace back to poor adhesion.
Apex Floor Preparation delivers the Concrete Surface Profile (CSP) your coating manufacturer specifies. From smooth CSP1 for thin-film sealers to aggressive CSP10 for heavy-duty broadcast systems, we match the method to the requirement.
CSP Profiles We Achieve
- CSP1 — Thin-film sealers, stains
- CSP2 — Thin-mil coatings, sealers
- CSP3 — Standard epoxies, self-levellers
- CSP4 — Thick-build systems, MMA
- CSP5 — Polyurethane screeds, heavy-duty coatings
- CSP6–7 — Overlay systems, cementitious toppings
- CSP8–9 — Heavy-duty mortar systems
- CSP10 — Thick broadcast, repair mortars
Our Surface Prep Methods
Diamond Grinding
Walk-behind and ride-on planetary grinders with diamond tooling. Opens the concrete pores and creates consistent CSP1–CSP4 profiles. Ideal for coating preparation and removing surface contaminants, laitance, and thin coatings.
Shot Blasting
Steel shot propelled at high velocity to abrade the surface. Achieves CSP3–CSP8 profiles with excellent uniformity. Self-contained dust collection. Fast production rates for large floor areas.
Scarifying
Rotating drum with carbide cutters for aggressive material removal. Removes thick coatings, adhesive residues, and deteriorated concrete. Creates CSP6–CSP10 profiles for maximum mechanical bond.
Dust-Controlled Operations
All our grinding and surface prep equipment operates with integrated dust extraction. H-class HEPA filtration captures respirable crystalline silica (RCS) at the source—protecting workers, adjacent areas, and sensitive equipment.
Industrial vacuums — H-class HEPA filtration direct to machine
Shrouded tooling — Capture at the cutting head for maximum efficiency
Air quality monitoring — Available for sensitive environments on request
