How do you know when it's time to replace a garage floor coating?

Replace the coating when you see: coating lifting or peeling at multiple locations (delamination), topcoat worn through to the flake layer in high-traffic areas, bubbling or blistering across more than a small area, or UV yellowing that can't be cleaned. Surface scuffs, minor tire marks, and localized wear in one spot are not reasons to replace the entire coating.

How long should a garage floor coating last before replacing in Texas?

A professionally installed polyaspartic system in Katy TX should last 15–20 years before needing replacement. Standard epoxy typically lasts 3–7 years. If your coating is failing within the first 5 years, it's a product or installation failure — not normal wear.

When to Replace Garage Floor Coating — Katy TX | Katy Floors Epoxy

Not every mark or scuff on a coated garage floor means the coating needs to go. But some conditions are genuine warning signs that the coating is failing and replacement will only get harder the longer you wait. Here's how to tell the difference.

Signs to Replace Now

Delamination/peeling: Coating lifting from the slab in sheets or patches. Once it starts, water gets underneath and accelerates the failure. Replace now — the area that's peeling today will be twice as large in six months.
Bubbling or blistering: Moisture vapor from below the slab pushing the coating up. Blisters that keep spreading mean the slab moisture problem is ongoing. Replacement without addressing the moisture source will fail again.
UV yellowing of white or light areas: Standard (non-UV-stable) epoxy turning yellow-orange in sun-exposed areas. This is a product failure — the topcoat is degrading. Cleaning won't reverse it.
Topcoat worn completely through: Bare epoxy or flake layer exposed without protective topcoat. The system is now porous to oil and chemical staining.

Signs You Can Probably Wait

Small localized scuffs or scratches that don't expose the flake or base coat
Tire marks that clean off with degreaser
Surface dulling in tire tracks after many years of use (normal wear, not failure)
One or two small chips from heavy impact — not spreading

The cost of waiting on delamination: A 2-square-foot delaminated area that you let go for a year often becomes 20 square feet. Water infiltrates under the coating and lifts it aggressively from the edges. Early replacement is always cheaper than late replacement.
