Garage Floor Coatings in Lafayette, Orinda & Moraga
Lafayette and Orinda have the oldest homes in the area, with a median year built of 1960 (Census ACS). On a slab that old, the coating is the easy part. Crack repair, old-finish removal and a moisture test are what make it last.

What a 60-year-old garage slab usually needs
Expect some combination of these before any coating goes down:
- Shrinkage and settlement cracks routed, filled and ground flush
- Old paint, sealer or a failed DIY coating ground off completely
- Oil-soaked areas degreased and ground out
- Spalled or pitted patches leveled
- A moisture test, since nobody can tell by looking whether an old slab has a vapor barrier underneath
Details on each step are in prep and crack repair. When most of the surface is scaled or uneven, resurfacing first runs about $3–$7+ per sq ft (HomeGuide).

FAQStraight answers
Local questions
Can a 1960s garage slab be coated?
Usually, once cracks are repaired, old finishes are ground off and a moisture test comes back within the product’s limit. Slabs that are heaving or broken apart need concrete work first.
Who issues building permits in Lafayette?
Lafayette handles zoning but contracts with Contra Costa County Building Inspection for building permits (City of Lafayette). Coating work by itself rarely needs one; electrical work for a charger or lighting does.
Is acid etching enough on an old slab?
No. Old slabs often carry paint, sealer and oil that acid doesn’t remove. Diamond grinding is the standard for a coating meant to last.
