Epoxy Garage & Commercial Floor Coatings in Gaithersburg, MD

Epoxy flooring is a resin-based coating system applied over properly prepared concrete to create a bonded finished surface. The coating creates a seamless, cleanable, decorative surface that protects the concrete beneath it. It is a coating — not a structural repair — and it depends entirely on the slab's condition and the quality of surface preparation for its performance.

In Gaithersburg and across Montgomery County, epoxy coatings are considered for residential garages, workshops, utility areas, commercial floors, service areas, and storage spaces. The coating is chosen for its appearance, its cleanability, and the surface protection it provides depending on the system.

We do not call every resin floor epoxy if another chemistry is used. Where a different resin system is more appropriate for the use, we say so. This page is about epoxy coatings applied over suitable concrete — for the structural garage slab itself, see our garage floors page, and for mechanically refined or sealed finishes, see our polished concrete and grind and seal pages.

An epoxy coating may make sense when the goal is an easier-to-clean finished surface, a decorative appearance, or surface protection on a suitable slab. Common uses include residential garages, workshops, utility areas, commercial floors, service areas, and storage spaces where the concrete is stable and the surface can be properly prepared.

What Epoxy Does Not Fix

An epoxy coating should not be presented as a fix for structural problems. It will not correct:

• Structural cracking or slab movement
• Slab settlement or uneven floors
• Active moisture transmission through the concrete
• Major spalling or severely deteriorated concrete
• Unstable or failing slab conditions

These conditions may require concrete repair or replacement before a coating is applied. A coating over an unstable or wet slab can fail to bond, blister, or peel. We evaluate the slab and the moisture conditions before recommending epoxy.

A durable epoxy coating depends on preparation. The concrete is evaluated, cleaned, and mechanically profiled so the coating bonds to the surface rather than sitting on top of contamination.

1. 1Slab evaluation — assess the concrete condition, cracks, and surface.
2. 2Moisture review — check for vapor or moisture conditions that could affect bonding.
3. 3Cleaning — remove dirt, oil, grease, and contamination from the surface.
4. 4Mechanical surface preparation — profile the concrete so the coating bonds.
5. 5Crack and joint assessment — review how existing cracks and joints will be treated.
6. 6Localized repair — address spalls, small cracks, or surface defects before coating.
7. 7Dust removal — clean the prepared surface so nothing interferes with adhesion.
8. 8Primer where applicable — apply a primer suited to the system and the slab.
9. 9Coating application — apply the epoxy coating over the prepared floor.
10. 10Decorative broadcast and flakes where offered — add color flakes where part of the system.
11. 11Topcoat where part of the selected system — apply a protective topcoat for the intended use.
12. 12Curing before use — allow the system to cure before the floor returns to service.

We do not provide DIY chemical recipes or specify proprietary systems. The preparation steps, the number of coats, and the cure time depend on the selected system and the slab conditions.
