California Climate & Code Notes
Strict Title 24 energy codes, low-VOC chemical regulations, and seismic reinforcement rules increase pro installation labor.
Pro Field Notes
- 100% solids epoxy and polyaspartic coatings require mechanical diamond grinding (CSP-2 profile) to prevent hot-tire pickup.
- Always test slab moisture first; if vapor emissions exceed 3 lbs/1,000 sq ft, use a 2-part moisture vapor barrier primer.
- Aliphatic polyaspartic topcoats cure in hours and resist UV yellowing near open garage doors.
