Before installation
Epoxy floor preparation: what customers should know before installation
Preparation is not a boring technicality. It is the foundation of adhesion, appearance and long-term performance.
The short version
Ask what preparation method is being used and what happens if the slab reveals a problem. The answer matters more than a glossy promise.
Why concrete preparation matters
Coatings need a clean, sound and suitably textured surface to bond to. Dust, oil, laitance, old paint, curing compounds and weak concrete can interfere with adhesion. Even a premium resin cannot compensate for a contaminated or poorly prepared base.
What preparation may include
The exact process depends on the slab, but a professional scope may include mechanical grinding, vacuuming, crack and joint treatment, edge work, repairs and a moisture assessment. The aim is to create a consistent surface for the specified system.
- Removal of loose or incompatible material.
- Mechanical profiling rather than simply masking the surface.
- Repairs discussed before they are covered.
- Dust control and a clean work area.
- A clear decision if moisture or slab movement needs attention.
What you can do before the crew arrives
Clear personal items and confirm which heavy items the contractor will handle. Let the team know about floor wastes, drains, fixed cabinetry, expansion joints, previous spills or areas that have been repaired. Good information helps the installation plan run smoothly.
Do not confuse speed with efficiency
A fast installation can be efficient when the plan is sound, but skipping preparation is not efficiency. Ask how long each stage needs, whether the floor is being mechanically prepared and what the return-to-service plan is before you book around the work.
