Epoxy Floor Preparation
An epoxy floor can only perform as well as the concrete beneath it. A slab can look clean and still carry failed coating, adhesive residue, weak surface material, or a profile that doesn’t suit the epoxy system being installed.
We prepare concrete for epoxy floors across Vancouver, Langley, and the Lower Mainland. We’ll review the slab, the existing material, and the coating requirements before selecting the preparation method that fits the work.
Start With the Concrete, Not the Existing Finish
Before epoxy goes down, we need to understand what’s already on the floor and what the concrete will support. Old coatings can conceal weak material. Adhesive residue can interfere with bond. Smooth concrete doesn’t always provide the mechanical profile epoxy needs.
We assess the concrete, not just the visible finish. That means your team isn’t pricing a new coating system over unknowns.
- Existing epoxy, paint, sealers, adhesives, and flooring materials
- Weak concrete, contamination, high spots, and rough transitions
- The surface profile required by the epoxy specification
- Open slab areas, edges, repair zones, and detailed correction work
- Access, recovery, and dust-control requirements for the site
Match the Preparation Method to the Floor Condition For
A new slab, a failed epoxy floor, and a repair-and-recoat project don’t start from the same place. The preparation plan has to reflect the concrete condition, the material already in place, and the requirements of the coating being applied.
Surface condition | Preparation objective | PDB method |
Open, exposed concrete | Create a consistent mechanical profile for epoxy | Shot blasting |
Failed epoxy, paint, or coating buildup | Remove weak material and expose sound concrete | Floor removal, grinding, or shot blasting |
Adhesive residue or existing flooring | Expose and assess the concrete substrate | Floor removal and grinding |
High spots, repair edges, and transitions | Correct detailed areas before coating | Diamond grinding |
Localized damage or weak surface areas | Prepare sound concrete for repair or sealing | Surface preparation and grinding |
Shot Blasting for Large Epoxy Floor Areas
When a wide concrete slab needs a repeatable mechanical profile, shot blasting can strip, clean, and texture the floor in one dry process. You won’t have to build additional drying time into the preparation sequence.
Our fleet includes eight-inch electric blasters, sixteen-inch diesel ride-on units, and thirty-inch electric blasters. That range lets us match the machine to the floor area and production requirement instead of working a large slab with equipment that is too small for the scope.
Vacuum recovery collects steel shot and debris as work progresses. Once blasting is complete, we’ll review the concrete for the cleanliness, texture, and profile required before epoxy work begins.
Diamond Grinding for Edges, Repairs, and Detailed Work
Shot blasting works well across broad open areas, but it isn’t the right answer for every detail. High spots, failed coating residue, repair boundaries, doorways, and transitions can all need diamond grinding.
We use precision diamond grinding and dust-controlled equipment to remove residual material, correct local inconsistencies, and improve surface consistency around detailed work.
That keeps repair areas and transitions aligned with the preparation requirement for the rest of the floor.
Remove Failed Epoxy Before Recoating
A new epoxy system shouldn’t be installed over failed or poorly bonded material. Before a recoating scope is finalized, the old epoxy has to be removed so the concrete can be assessed.
We remove failed epoxy, adhesives, tile, carpet, vinyl, wood flooring, rubber, and other existing floor systems. Our quiet, battery-powered floor scrapers are practical for enclosed or occupied spaces where propane-powered equipment is not appropriate.
Once the existing material is removed, we’ll clean and assess the exposed concrete before preparing it for repair, sealing, recoating, or a new epoxy system.
Coordinate Access and Staging Before the Epoxy Crew Mobilizes
Architectural concrete requires care, consistency, and attention to detail. Whether you need a decorative concrete blasting finish in Burnaby, an exposed aggregate concrete finish in Delta, or a clean, uniform surface for a new build in Vancouver, PDB has the skill and equipment to deliver dependable results.

Let’s Get Started
Bring us in before the epoxy schedule is fixed. We’ll identify what has to be removed, corrected, and profiled, then prepare the concrete for the coating being installed.
