Polyaspartic Floor Coating in Bowling Green, KY

Polyaspartic floor coating is a type of polyurea that cures much faster than epoxy and resists sunlight far better. In Bowling Green we use it as a full system or as the topcoat over an epoxy base, depending on the floor. It suits garages that face west, porches and anyone who needs their garage back quickly.

How it compares to epoxy

HomeGuide's comparison lays out the main differences:

• Cure time: polyaspartic fully cures in 1 to 2 days; epoxy can take up to a week.
• UV resistance: polyaspartic is rated excellent; epoxy is poor to fair and can yellow.
• Flexibility: polyaspartic is highly flexible; epoxy is more brittle.
• Application temperature: polyaspartic has a wide range, listed at -30°F to 140°F; epoxy is limited.
• Coat thickness: polyaspartic goes on at 2 to 6 mils per coat; epoxy at 10 to 20 mils.

Epoxy builds thickness faster, and polyaspartic resists sun and wear better. That is why many of our floors use both: an epoxy base for build, and a polyaspartic topcoat for the surface you see.

Why it fits this climate

Bowling Green summers are long and hot, with about 41 days a year at 90°F or above. A garage with the door open to the afternoon sun puts a lot of UV on the first few feet of floor. Epoxy in that strip can amber over time. Polyaspartic keeps its color. Winters are mild by comparison, with January averaging 35.7°F, but cold snaps still happen, and polyaspartic's wider temperature range gives us more working days in the shoulder seasons.

Flexibility on a slab that moves

The clay soil over limestone in this area expands and settles with wet and dry periods. Slabs flex slightly through the year. A more flexible coating handles small movement better than a brittle one. It can't bridge a crack that keeps opening, though, so any active crack gets looked at before we coat.

Fast return to service

HomeGuide says polyaspartic is dry to the touch within a few hours and ready for vehicles in 24 to 48 hours. For homeowners with one garage and no other place to park, and for businesses that can't close for a week, that speed is the main reason to choose it.

The trade-offs

Polyaspartic sets fast, so it has to be applied quickly by a crew that has used it before. It costs more per square foot than epoxy. And it only bonds as well as the prep allows, so the slab still has to be ground and repaired first.

Where we use it most

• West-facing garages where the afternoon sun hits the floor
• Covered porches and breezeways
• Garages that can't be out of use for a week
• Business floors that need to reopen the next day
• Topcoats over flake and metallic floors for added wear resistance
