Quick answer
How much does a garage floor coating cost in Frederick, MD?
Professionally installed epoxy or polyaspartic systems generally run $5 to $9 per square foot, putting a standard two-car garage of about 500 square feet between $2,300 and $4,500. If an old coating has to come off first, add roughly $2 to $5 per square foot for removal. Roll-on painted floors quoted at a fraction of this are a different product — a thin painted film, not a coating system — and they do not last.
The work
What floor & deck coatings actually involves.
A traffic coating is a waterproofing membrane you are allowed to walk and park on. On an elevated balcony or walkway it is the only thing keeping water out of the structure below, which is why a failed one gets expensive well before it looks bad.
On a garage or basement floor the job is different: resisting hot tyres, road salt, oil and freeze-thaw, and doing it without the coating peeling off in sheets the second winter. Both come down to the same thing — surface preparation.

What’s included
Everything the floor & deck coatings scope actually covers.
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
Surface prep that actually bonds
01Diamond grinding or shot blasting to an open profile, not an acid wash and hope. Coatings fail at the bond line, and the bond line is made here.
Moisture and crack testing
02Slab moisture tested before anything is applied, and cracks routed and filled — coating over an active crack just reprints it.
Balcony and walkway systems
03Pedestrian traffic coatings for elevated decks and walkways: base, reinforcement, and a wear coat, detailed properly at edges, drains and upstands.
Garage and basement floors
04Epoxy and polyaspartic systems that handle hot-tyre pickup, road salt and oil — the three things that kill a big-box roll-on kit.
Slip resistance built in
05Aggregate broadcast into the system to a level you choose, because a wet coated balcony with no grip is a liability.
Recoat and repair
06Assessing and recoating existing systems that are worn but sound, rather than defaulting to a full tear-off.
And the damage underneath
07A balcony over living space leaks into framing, drywall and paint below. We repair that too — the whole failure, not just the surface it started on.
HOA and multi-family
08Pedestrian and vehicular traffic coatings for condo balconies, elevated walkways and shared decks, quoted by the building rather than the unit.

Floor & Deck Coatings questions

A traffic coating is a liquid-applied waterproofing system that cures into a seamless membrane tough enough to be walked or driven on. It is trade vocabulary for the same family of products sold to homeowners as deck waterproofing, balcony coating or garage floor coating. If you have a condo balcony, an elevated walkway or a deck over living space, that is the system you want.
Yes — and that is a job most coating contractors will only do half of. The coating stops the water, but the water that already got through has been in the framing, the drywall and the paint underneath. We do both: waterproof the deck and repair the ceiling, framing and finish below it, on one contract with one crew. That is the whole reason we run eleven trades rather than one.
A sealer soaks into the surface and slows water down. A coating is a membrane that sits on top and stops it. On a patio slab a sealer is usually enough. Over living space it is not — anything with a room underneath needs a real waterproofing membrane, and a sealer sold as one is the single most common cause of a leaking balcony.
Nearly always inadequate surface preparation. A concrete slab has to be mechanically profiled — ground or shot blasted — so the coating has something to key into. Acid etching and a quick clean, which is what most DIY kits call for, does not produce a reliable bond, and the coating lifts with the first hot tyre or freeze cycle.
Epoxy builds thickness cheaply and is a proven garage floor system. Polyaspartic cures far faster — often a one-day turnaround — holds colour better under UV, and stays more flexible in cold, which matters for Maryland winters. Polyaspartic costs more. Many of the best floors use both: an epoxy base with a polyaspartic topcoat.
Not before finding out why. A coating applied over an active leak or a wet slab traps the water and fails. We test slab moisture, check the detailing at drains and edges, and fix the cause first — otherwise you have paid for a membrane that is already compromised.
A properly prepared and installed garage floor system typically gives ten to twenty years. Exposed pedestrian traffic coatings on balconies see UV and weather and generally want inspection at around five years and a wear-coat refresh somewhere in the seven-to-twelve-year range — refreshing the wear coat on time is far cheaper than replacing the system.
