Surface Preparation

Mechanical concrete surface preparation — diamond grinding, shot blasting, scarifying, crack repair, and slab profiling. Standalone or as part of a complete floor system. The step that determines whether any coating lasts or fails.

Why Surface Preparation is Everything

The Single Most Important Step in Any Floor System

The majority of floor coating failures are not product failures — they are surface preparation failures. Coatings applied to contaminated, sealed, or inadequately profiled concrete will delaminate regardless of the quality of the material applied on top. Every system we install starts with proper mechanical preparation.

We offer surface preparation as a standalone service for GCs, flooring contractors, and property managers who need the concrete ready for another trade — tile setters, flooring installers, or coating applicators. We prepare the slab to the profile and specification required by the finish system going on top.

  • Diamond grinding — surface leveling and profile creation
  • Shot blasting — large-area prep for industrial and commercial floors
  • Scarifying — coating and adhesive removal, heavy surface profiling
  • Crack repair and patching — structural and non-structural cracks
  • Joint filling — control joint and construction joint preparation
  • Moisture testing — MVER assessment before coating specification

Methods

Surface Preparation Methods

Most Common — Profile & Level
Diamond Grinding

Diamond grinding uses segmented diamond tooling to mechanically abrade the concrete surface to the required CSP (Concrete Surface Profile). Opens the pore structure for maximum coating adhesion, removes surface laitance and contamination, and can be used to level minor high spots and ridges. The standard preparation method for most commercial and industrial coating projects.

CSP achieved: CSP 1–4 depending on tooling and passes
Large Area Industrial
Shot Blasting

Shot blasting propels steel shot at high velocity across the concrete surface using a self-contained, vacuum-equipped blast machine. Highly efficient for large warehouse and industrial floor areas. Creates a consistent CSP across the entire floor area rapidly. Excellent for removing existing coatings and contamination while creating the ideal profile for high-build epoxy and urethane systems.

Best for: Large industrial floors, warehouses, distribution centres
Concrete & Slab Repair
Crack Repair & Patching

Cracks and spalled areas are repaired before any coating is applied. Non-structural hairline cracks are filled with flexible epoxy injection or polyurea crack filler. Structural cracks are routed, cleaned, and filled with rigid epoxy. Spalled areas are ground back to sound concrete and patched with fast-setting repair mortars or hybrid concrete repair compounds. The condition of the slab after repair directly impacts the final appearance and longevity of the coating system.

Materials: Epoxy injection, polyurea, fast-set repair mortar, hybrid concrete repair
Pre-Coating Assessment
Moisture Testing & Slab Assessment

Before specifying any coating system, we test the concrete slab for moisture vapor emission rate (MVER) using calcium chloride or relative humidity probe testing methods. High moisture can cause coating failure regardless of preparation quality. If moisture is elevated, we specify the appropriate moisture vapor barrier primer or DualGuard/VersaGuard penetrating system before the topcoat. Proper moisture assessment prevents costly failures.

Testing: ASTM F1869 calcium chloride, ASTM F2170 relative humidity probe
