Concrete is porous by nature — without a protective sealer, stains, vehicle fluids, oils, and chemicals penetrate the surface and cause deterioration from within.
Concrete sealers create a protective barrier that either penetrates the concrete and chemically bonds to the substrate (penetrating sealers) or forms a protective film on the surface (topical sealers). Property Prep Services has been specifying and applying concrete sealers for parking structures and commercial lots across Greater LA since 1991.
Since 1991, serving parking lots and commercial facilities across Greater Los Angeles.
