How to hire a garage floor coating company in Sunnyvale
Ask what they do to the concrete first. Diamond grinding beats acid etching every time.
Polyaspartic topcoats resist UV yellowing and hot-tire pickup better than plain epoxy.
Get the warranty in writing: what it covers, for how long, and who honors it.
Look at photos of their work after a year, not just the day it was finished.
Garage Floor Coating Company questions, answered
How long does a garage floor coating take?
Most residential garages are coated in one or two days, including surface prep. Fast-cure polyaspartic systems can usually take foot traffic the same day and cars within a day or two.
Epoxy or polyaspartic?
Epoxy is thicker and cheaper; polyaspartic cures faster, flexes more and does not yellow in sunlight. Many installers use an epoxy or polyurea base with a polyaspartic topcoat.
Can a coating go over a cracked or stained slab?
Yes, if the crew repairs the cracks and grinds the surface first. Moisture problems in the slab need to be tested before coating.
