Flake, metallic, and solid-color epoxy finish for Rockville garages. Half this city was built before vapor barriers existed and half after 2000 — we prep each slab for what it actually is. 3-day typical turnaround.
Rockville is really two housing stocks wearing one zip code, and an epoxy finish that lasts has to respect which one your garage belongs to.
The first Rockville is the postwar one — Twinbrook, Hungerford, Lincoln Park, the rambler and split-level neighborhoods poured in the 1950s and 60s. Those slabs are sixty-plus years old, and most went down before polyethylene vapor barriers were standard practice under residential concrete. Ground moisture rises through them continuously. You cannot see it or feel it, and it is the number one reason garage coatings fail in older Montgomery County homes: the film goes down over invisible vapor drive and releases in sheets two years later.
The second Rockville is King Farm, Fallsgrove, and the town-center construction from the late 1990s onward. Those slabs have vapor barriers — but they were power-troweled to a hard, closed finish and sprayed with curing compound, which leaves almost nothing for a coating to grip. A cheap acid-etch prep barely touches them.
Our process handles both, because it does not guess. Every Rockville slab gets a moisture reading before we quote — calcium chloride per ASTM F1869 or a relative-humidity probe per ASTM F2170. Our flake system tolerates vapor transmission up to 12 lb per 1,000 sq ft per 24 hours, a high ceiling that most slabs clear; when a Twinbrook-era floor reads over it, a moisture-barrier primer (about $280) goes down first, and we show you the number that justified it. And every slab, old or new, gets diamond ground to a CSP-3 profile — the mechanical tooth that acid etching cannot produce on either hard-troweled new concrete or sixty-year-old cured slabs.
That is the whole difference between an epoxy finish that looks good at the open house and one that still looks good when the car has parked on it through ten Maryland winters.
We cover all of Rockville — 20850, 20851, 20852, 20853 — including Twinbrook, King Farm, Fallsgrove, Hungerford, College Gardens, and Rockville Town Center, plus North Bethesda, Derwood, and Garrett Park next door.
Montgomery County homeowners already know us from our hardwood work in Rockville, Bethesda, and Potomac — the epoxy crew runs the same way: our own installers, written scope, MHIC #111360 on every contract.
Postwar slabs are usually better concrete than their age suggests. Mid-century pours cure hard over sixty years. Once the moisture question is answered and the surface is ground open, a Twinbrook slab takes a coating beautifully — often better than modern production concrete.
Winter brine is the real enemy. Rockville Pike, I-270, and the Beltway are heavily salted, and everything your tires carry in sits on the slab until spring. Bare concrete absorbs it and pits at the door line. A sealed floor rinses clean.
Townhome garages in King Farm run narrow. Single bays around 12×20 favor epoxy — the floor is the most visible surface in the room, and our pricing scales honestly: mobilization is fixed, so the per-square-foot rate is higher on a small bay and we say so up front rather than burying it.
Slab age decides the prep, not the price sheet. The moisture primer is the only age-related line item, it costs about $280, and it only appears when a test reading says so.

Industrial diamond grinders on every job. No acid-etching shortcuts. The bond is permanent, even in salt-air Rockville garages.
A standard 2-car garage of about 380 square feet runs roughly $3,100 with an epoxy clear topcoat and about $3,600 with polyaspartic, installed. A single-bay townhome garage lands in the mid-$2,000s. Older Twinbrook-era slabs sometimes add a $280 moisture-barrier primer, but only when the moisture test says it is needed. You can price your own garage instantly on our epoxy cost calculator.
Almost always, and often with excellent results — sixty-year-old concrete is fully cured and hard. The one thing we insist on is a moisture test first, because pre-1970 slabs usually lack a vapor barrier. If the reading is over our system limit of 12 lb per 1,000 sq ft per 24 hours, a moisture-barrier primer goes down before the epoxy. Coating an untested older slab is how floors end up peeling in sheets.
Yes. Newer slabs there have vapor barriers, so the moisture primer is rarely needed — but they are power-troweled and sealed with curing compound, which makes surface prep matter more, not less. We diamond grind to a CSP-3 profile; acid etching barely marks a hard-troweled slab, and coatings applied over it tend to fail at the two-year mark.
The base build is the same 100% solids epoxy with flake broadcast. The topcoat differs: polyaspartic is UV stable, so it will not amber where sun comes through the garage door, and it cures fast enough to park on in about a day. Epoxy clear costs less but can yellow in direct sun and needs a longer cure. If your garage faces south, take the polyaspartic.
Three days is typical: grinding and prep, base coat and flake, then topcoat. Foot traffic after about 24 hours, vehicles at 72 hours with polyaspartic. We hold the vehicle line firmly — hot tire pickup from parking too early is one of the few ways to damage a properly installed floor.
Yes — garage floor coating on a residence is home improvement work under Maryland law, and the contractor’s MHIC number belongs on the contract. Ours is MHIC #111360, on every estimate and agreement we write, in Rockville and everywhere else in Maryland.
Included: material, labor, prep work, basic subfloor leveling, demo of existing flooring, and disposal. Not included: shoe molding or baseboard replacement (separate carpentry quote), appliance disconnection or reconnection, and major subfloor replacement beyond patching. We quote those separately if needed — no surprises.
