What does concrete preparation actually involve before a flake floor goes down?

The slab is ground or mechanically cleaned to remove surface contaminants and create a profile—a slightly rough texture that gives the epoxy something to grip. Without this step, the coating bonds only to whatever is sitting on top of the concrete rather than to the concrete itself, which is a primary cause of delamination.

How are cracks in the slab handled before coating begins?

Cracks are filled and allowed to cure before any base coat is applied, because a coating applied over an open crack will mirror that crack as the slab continues to move. The repair method depends on whether the crack is active or dormant, which is assessed during prep.

What happens during the flake broadcast and why does it matter?

Flakes are thrown by hand across the wet base coat in passes until the desired coverage is reached. The angle, distance, and rate of broadcast all affect how the chips land and overlap, so this step requires consistent technique across the entire surface to avoid thin spots or uneven density.

How do slab-on-grade garages in Vancouver affect the coating schedule?

Slab-on-grade construction means the concrete sits directly on the ground, so moisture vapor transmission through the slab is a factor that gets checked before coating. If moisture readings are elevated, the prep approach is adjusted to reduce the risk of the coating blistering from below.

What does a finished flake floor look like when it is ready for use?

The topcoat cures to a consistent sheen, the chips are fully encapsulated, and there are no visible seams or lap marks between passes. You can walk on the surface, and tires can return, once the topcoat has reached its full cure—the schedule for that is set before the job begins so there are no surprises.

Flake Epoxy Flooring

Tru Resins installs flake epoxy floors for garages, basements, and commercial spaces across Vancouver and Clark County. The owner handles every install personally, with experienced helpers brought in as the job requires, so the person who walked the space and quoted the work is the same person applying the coating. This matters most when prep decisions—like how aggressively to grind a slab or whether a crack needs structural fill before coating—get made on the fly during the job rather than delegated to someone unfamiliar with the original scope.

The process runs in a set sequence over approximately two days. First, the concrete is ground or cleaned to open its surface and give the epoxy a mechanical profile to bond to. Cracks are repaired before any coating goes down because patching under a finished floor is not possible. A pigmented base coat is applied, then flakes are broadcast by hand across the wet surface—coverage and density are controlled at this stage, so the broadcast technique directly affects the final appearance. Once the base has cured within its window, a clear topcoat seals the flakes and provides the wear surface. Neighborhoods like Hazel Dell and Felida see a lot of attached slab-on-grade garages where this system is a direct fit: the existing slab becomes the substrate, and no new concrete is poured.

Request an on-site evaluation to review your slab condition and discuss finish options before scheduling the install.

The flake broadcast step does more than add visual texture. The chips interlock into the base coat while it is wet and become encapsulated by the topcoat, which creates a layered wear surface rather than a single thin film. The result is a floor that resists abrasion from tires, foot traffic, and shop equipment without the coating separating from the chip layer. When you run your hand across a finished flake floor, you feel a slight texture rather than a slick sheet—that texture is what provides grip and prevents the topcoat from reading as a plain glossy surface.

After the topcoat cures, the floor cleans with a mop and household cleaner. Oil drips, tire marks, and concrete dust—the three most common garage floor complaints—no longer bond to the surface the way they do on bare concrete. The coating does not stain through normal use, and the multi-tone chip pattern means minor scuffs are not visible the way they would be on a solid-color floor.

Flake density and chip size are chosen before the install, and those decisions affect how busy or subdued the finished floor reads. A full-broadcast system covers nearly all visible base coat and produces a uniform chip appearance, while a partial broadcast leaves more base coat showing and creates a more mottled look. Tru Resins goes over both options during the estimate so the choice is made before any material is mixed.
