Garage Floor Painting in Walnut Creek — FAQ

Garage floor paint vs. epoxy — what is the difference?+

Paint is a single-component coating that sits on the surface. Epoxy is a two-part chemical bond that is much harder and more durable. Paint costs 40–60% less but may need recoating in 2–3 years.

How long does garage floor paint last?+

Concrete floor paint lasts 2–4 years with regular vehicle traffic. In low-traffic garages (storage, workshop), it can last 5+ years.

Can I paint over old garage floor paint?+

Yes, if the existing paint is well-adhered. Lightly sand or etch the surface for adhesion, clean thoroughly, and apply new coats directly over the old paint.
