Polyaspartic topcoat

Polyaspartic topcoats add $500–$1,200 to material costs for a typical 400-square-foot garage compared to polyurethane, but total installed cost differences are smaller at $0–$600 due to reduced labor from faster cure times. Over 20 years, polyaspartic systems cost 25–40% less when factoring in re-coating needs for polyurethane.

Garages with windows, frequent door-open time, or south/west exposure will show measurable yellowing in polyurethane topcoats within 18–36 months in Woodland Hills' intense UV environment. UV-stable polyaspartic topcoats prevent yellowing for 15+ years regardless of sun exposure.

Yes, but the yellowed base layer must first be lightly abraded to create mechanical bond, and the yellowing won't reverse—it will be sealed beneath the new topcoat. For best results, contact Five Star Epoxy & Coatings at (818) 355-3804 for professional assessment and topcoat removal if necessary.

Polyaspartic topcoats cure to light foot traffic in 1–2 hours and allow vehicle return within 24 hours, compared to 48-hour foot traffic wait and 5–7 day vehicle wait for polyurethane topcoats. Most Woodland Hills installations complete in one day with same-evening access.
