Polyaspartic floor coating
Polyaspartic is what you buy when you need the floor back tomorrow, the space gets sunlight, or it is February.

Quick answer
Is polyaspartic worth the extra cost over epoxy?
In three situations, clearly yes: where the floor gets real daylight and an epoxy top coat would amber, where you need the space back within a day, and where the slab is too cold for epoxy to cure properly. In a sunless interior workshop where chemical resistance is the priority and time is not, epoxy at $5 to $9 does the job for less than polyaspartic at $7 to $12. We will tell you which case you are in.
The work
What polyaspartic actually involves.
Polyaspartic is an aliphatic polyurea, and three of its properties are the reason it has largely taken over the top end of this trade. It cures remarkably fast, which makes a one-day installation realistic and a next-day return to service normal. It is ultraviolet stable, so it does not amber the way epoxy does in a sunlit space. And it stays flexible at low temperature and will cure on a cold slab, which in an unheated Maryland garage in January is not a minor advantage.
The cost of those properties is money and working window. Polyaspartic costs meaningfully more per square foot than epoxy, and its fast cure means the crew has a short time to get each coat down and broadcast correctly — there is no going back to fix a patch twenty minutes later. That is a reason to care who is installing it rather than a reason to avoid it, but it is also why a polyaspartic quote from somebody who has never used it is worth less than it looks.
The preparation is identical and is still where the job is won or lost. Diamond grinding or shot blasting to an open profile, slab moisture tested, cracks routed and filled. Polyaspartic bonds extremely well to properly prepared concrete and no better than anything else to a sealed, polished slab. A fast-curing premium product over bad prep fails exactly as reliably as a cheap one.

What polyaspartic costs in Maryland
Maryland polyaspartic systems, installed. Prep condition drives price more than the coating does. Flake density moves the material cost within these bands.
- Polyaspartic floor system, installed
- $7 – $12 per square foot
- Two-car garage in polyaspartic (approx. 500 sq ft)
- $3,500 – $6,000
- Full-refusal flake broadcast
- $9 – $15 per square foot
- Epoxy base with polyaspartic topcoat
- $7 – $12 per square foot
- Removing an existing failed coating
- $2 – $5 per square foot
- Cold-weather installation
- no surcharge

What’s included
Everything the polyaspartic 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.
Same preparation, no shortcuts bought
01Diamond ground or shot blasted to profile, moisture tested, cracks routed and filled — the premium product does not substitute for any of it. We mention this because the fast cure sometimes gets sold as though it replaced the prep, and it does not.
One-day installation where the floor allows
02Grind, repair, base coat, broadcast and topcoat inside a single working day on a sound slab, with the floor walkable that evening and usually driveable within 24 hours. Where the slab needs significant repair first we will say so and plan two days.
Cold-weather installation
03Slab temperature measured and the product specified for it, which is how coating gets done in a Maryland January rather than being deferred to spring. Epoxy in those conditions cures slowly or incompletely; polyaspartic does not.
UV stability for sunlit spaces
04Specified where daylight reaches the floor — a garage with glazing, a sunroom slab, a covered patio — because the colour holds rather than drifting yellow. This is the single commonest reason we recommend it over epoxy.
Flake broadcast to full refusal, or graded
05Decorative flake broadcast to the density you choose, up to full refusal for a seamless terrazzo-like surface, then back-rolled and topcoated. Full refusal costs more in material and gives the most forgiving, most slip-resistant and best-looking result.
A crew that has done it before
06The short working window is real and it is why this product punishes inexperience. Each coat has to go down, get broadcast and get back-rolled inside its pot life, across the whole floor, in order. That is a scheduling and manpower question we resolve before the day, not on it.

Straight answers
Polyaspartic questions
Not covered here? Call and ask — you’ll get a real answer, not a “depends on the job”.
On a sound slab, yes, and that is routine rather than a claim — grinding, repair, base coat, flake broadcast and topcoat inside a working day, walkable that evening and usually driveable the next. What extends it is slab repair: significant cracking, spalling or an old coating to remove adds a day. We commit to the actual schedule at the estimate.
It is harder and more abrasion resistant than most epoxies, which is why it is used as a wear coat over epoxy rather than the other way round. What it is less good at is building thickness cheaply — it is applied thinner, so for deep impact resistance in a workshop an epoxy build with a polyaspartic wear coat beats either product alone.
Because the working window is short and unforgiving. Each coat has to be laid, broadcast and back-rolled across the whole floor inside its pot life, with no opportunity to return and correct a patch. It needs the right crew size and a planned sequence. That is a staffing question rather than a product problem, and it is worth asking whoever quotes you how many polyaspartic floors they have actually done.
Same crew, same visit
The rest of the floor & deck coatings work.
Most floor & deck coatings jobs are two or three of these at once, which is why they are priced and scheduled together rather than as separate call-outs.
