01 / Overview
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 CSP 1 for thin-film sealers to aggressive CSP 10 for heavy-duty broadcast systems, we match the method to the requirement.
Methods at a glance
| Method | Profile |
|---|---|
| Diamond grinding | CSP 1–4 |
| Shot blasting | CSP 3–8 |
| Scarifying | CSP 6–10 |
02 / Surface profile
Pick the profile. We’ll hit it.
Every coating and topping needs a specific concrete surface profile (CSP). Choose one to see what it suits and how we get there.
| Profile | Suits | Typical method |
|---|---|---|
| CSP 1 | Thin-film sealers, stains | Diamond grinding |
| CSP 2 | Thin-mil coatings, sealers | Diamond grinding |
| CSP 3 | Standard epoxies, self-levellers | Diamond grinding or shot blasting |
| CSP 4 | Thick-build systems, MMA | Diamond grinding or shot blasting |
| CSP 5 | Polyurethane screeds, heavy-duty coatings | Shot blasting |
| CSP 6–7 | Overlay systems, cementitious toppings | Shot blasting or scarifying |
| CSP 8–9 | Heavy-duty mortar systems | Scarifying (shot blasting to CSP 8) |
| CSP 10 | Thick broadcast systems, repair mortars | Scarifying |
03 / Methods
Our surface prep methods
03.1
Diamond grinding
Walk-behind and ride-on planetary grinders with diamond tooling. Opens the concrete pores and creates consistent profiles. Ideal for coating preparation and removing surface contaminants, laitance and thin coatings.
| Profile | CSP 1–4 |
03.2
Shot blasting
Steel shot propelled at high velocity to abrade the surface, with excellent uniformity and self-contained dust collection. Fast production rates for large floor areas.
| Profile | CSP 3–8 |
03.3
Scarifying
A rotating drum with carbide cutters for aggressive material removal. Removes thick coatings, adhesive residues and deteriorated concrete for maximum mechanical bond.
| Profile | CSP 6–10 |

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.
| Control | Detail |
|---|---|
| Industrial vacuums | H-class HEPA filtration, direct to the machine |
| Shrouded tooling | Capture at the cutting head for maximum efficiency |
| Air quality monitoring | Available for sensitive environments on request |
