Why We Focus on Wilmington
Wilmington is Coastal Spaces' primary market. We're locally owned, based out of the Southport and Wilmington areas, and Wilmington garages are what we work on most. When you call us, you're talking to someone who understands exactly what Wilmington's soil and groundwater conditions do to an unprotected garage slab.
Wilmington sits at an average elevation of just 32 feet, with a high water table and sandy coastal soils that produce elevated moisture vapor transmission (MVT) in nearly every garage slab in the city. From Landfall to Porters Neck to RiverLights to Midtown, this condition is consistent across ZIP codes and neighborhoods. It is the defining floor coating challenge in this market.
Why Polyaspartic and Not Standard Epoxy Installation in Wilmington
Standard epoxy floor coatings require relatively dry concrete — typically under 3 lbs per 1,000 sq ft per 24 hours of moisture vapor emission. Many Wilmington slabs test well above that level. When epoxy is applied to a high-MVT Wilmington slab, delamination isn't a risk — it's a scheduled event.
The failure compounds with UV degradation: aromatic epoxy topcoats yellow under Wilmington's coastal sun exposure, becoming brittle and less thermally stable over time. A UV-degraded epoxy floor under moisture pressure from below has a short remaining lifespan.
The polyaspartic topcoat is UV-stable — aliphatic chemistry means no yellowing under coastal sun. The water-insensitive epoxy base coat is rated for MVT up to 9 lbs — covering the majority of Wilmington slabs. When testing shows higher readings — common near Bradley Creek, Masonboro Sound, ICWW-adjacent lots, and low-lying south Wilmington properties — a full moisture mitigation primer is added before the base coat.
The System Used on Every Wilmington Installation
Industrial diamond grinding
Opens the concrete surface profile for resin adhesion; removes any existing sealers or prior coatings.
Calcium chloride moisture test
Placed at the estimate visit where indicators are present; 60–72 hour test determines MVT rate and drives the product specification.
Water-insensitive epoxy base coat
Applied on every Wilmington slab as standard; rated to bond over MVT up to 9 lbs.
Vinyl flake
Hundreds of colors available, all priced the same; broadcast into the wet base coat.
UV-stable polyaspartic topcoat
Aliphatic chemistry; no yellowing under coastal NC sun exposure.
Installation Schedule
Day 1: Crack repair, grinding, base coat, and flake.
Day 2: Topcoat. Light foot traffic ~24 hrs after topcoat. Vehicles ~48 hrs.
