Service · Charlotte Metro
Polyaspartic Top Coat locks in the finish.
The wear layer — UV-stable aliphatic polyaspartic applied over existing epoxy, flake, or metallic base. Fast-cure, one-day return-to-service, chemical and thermal resistance. This is what makes an epoxy floor actually last, not just look good at handoff.

The Overview
The layer every system lives or dies on.
People buy epoxy floors for the look. They keep the floor because of the topcoat. The base layer — flake, metallic, solid color — is the visual. Everything that touches the floor (hot tires, tool carts, chemicals, UV, cleaning products) hits the topcoat first. If the topcoat isn’t rated for the exposure, the whole system fails regardless of how perfect the base is. Most of the “failed epoxy” floors Robert tears up and redoes are failing at the topcoat, not the base.
Polyaspartic is the right topcoat for almost every residential and light-commercial application. It’s an aliphatic polyurea chemistry — UV-stable (doesn’t yellow), fast-cure (fully bonded in under 24 hours), chemical-rated (handles pool chlorine, automotive fluids, household cleaners), and thermal-shock tolerant (doesn’t delaminate when a hot tire parks on it). Two coats at spec film build, applied over a properly prepared base, is the gold standard for garage, basement, patio, and light commercial floors.
This service is specifically the wear layer — either over an existing coating that’s getting a refresh, or as the topcoat phase of a full new install. Robert will walk an existing floor, test bond strength, flag any substrate issues, and spec whether the existing system can accept a new topcoat or whether the old coating needs to come off first. An honest answer on what will and won’t work is the whole value of the walkthrough. Book the floor assessment and we’ll give you a real recommendation.
What’s Included
Topcoat work — refresh or full-system finish.
01 · Inspect
Bond & Chemistry Test
Existing coating inspected, bond-tested, and chemistry-verified. If the underlying system will accept a new topcoat, we proceed. If it won’t, we quote removal honestly instead of coating over failure.
02 · Scuff
Mechanical Scuff Sand
The existing topcoat is mechanically abraded to create profile for the new layer. Not a chemical etch — a physical sand that the polyaspartic can mechanically bond to.
03 · Clean
Degrease & Decontaminate
Professional-grade degreaser and solvent wipe pull every contaminant off the scuffed surface. Silicone, wax, grease, tire marks — all lifted before new coat goes down.
04 · Spot Repair
Color-Match Patching
Any chips, worn-through spots, or delamination in the base color layer are touched up and color-matched before topcoat. The polyaspartic seals the repair invisibly.
05 · Apply
Two-Coat Polyaspartic
Full spec film build — two coats rolled and back-rolled. Aliphatic, UV-stable, non-yellowing. Identical chemistry to what we apply on new installs.
06 · Cure
Next-Day Reopen
Walkable in six hours. Foot traffic overnight. Full rolling-load rated in 24. Most refresh jobs are a one-day closure — Monday morning shut, Tuesday morning back.
How It Goes Down
Half-day to one-day refresh. In and out.
Floor Assessment
Walk-through, bond-strength check, substrate documentation. Robert tells you honestly whether a topcoat refresh will work on your existing floor or whether the system needs a full redo. Written spec and quote either way.
Prep & Scuff
Floor cleared, mechanically scuff-sanded across the full surface, HEPA-vacuumed. Degrease and solvent wipe to pull any residual contamination. Spot patching where base-color damage exists.
Two-Coat Application
First polyaspartic coat rolled and back-rolled for even film build. Short cure window, then second coat applied same day. Full spec mil-thickness verified.
Cure & Handover
Walkable in six hours. Overnight cure for foot traffic and vehicles in 24. Robert walks the floor with you, flags any punch items, leaves a care sheet.
Common Questions
Topcoat-specific questions.
Can you put a polyaspartic topcoat over my existing epoxy garage floor?
Usually yes — if the underlying epoxy is still bonded to the slab. If the base layer is peeling, bubbling, or hot-tire lifting in spots, a new topcoat won’t fix the problem; it’ll just bond to a failing layer. Robert does a bond-pull test and documents the finding before quoting. The honest answer up front saves you from a second coating that fails faster than the first. Book the assessment.
What’s the difference between polyaspartic and polyurethane topcoats?
Polyaspartic is an aliphatic polyurea — UV-stable, non-yellowing, fast-cure, applied at higher film thickness, and rated for more aggressive chemical and thermal exposure. Standard polyurethane topcoats are thinner, slower-curing, and yellow under sustained UV. For garage, patio, basement, and light commercial work, polyaspartic is the right answer 95% of the time. Urethane cement is a different material family reserved for industrial applications.
How often does the topcoat need to be refreshed?
For normal residential garage use, every seven to ten years. For commercial wear — restaurants, retail, gyms — every four to six years. The polyaspartic wears down before the color base does. When it’s time, we scuff-sand and reapply a fresh two-coat topcoat. The color layer underneath stays permanent.
Will a new topcoat fix yellowing on an old floor?
If the yellowing is in the old topcoat — yes. We scuff that layer off and replace with aliphatic polyaspartic that won’t yellow. If the yellowing has penetrated into the base color layer, we may need to pigment-correct before topcoat. We’ll know after a quick floor inspection which situation yours is.
Can you topcoat an outdoor patio or pool deck?
Yes — and polyaspartic is specifically the right chemistry for exterior work because it’s aliphatic and UV-stable. For pool decks we typically incorporate an anti-slip aggregate into the topcoat layer. See the full outdoor program on our outdoor coatings page.
Do you do topcoat refresh outside Charlotte?
Yes — topcoat refresh work is typically a single-day job, which makes it efficient to cover the full Charlotte metro and regular travel to Lake Norman, Fort Mill, and Union County. Call (704) 775-1120 or see our service map.
