We're buying a home that has a stamped concrete driveway and patio. The concrete was then painted with a brownish acid stain and later sealed with a clear coat. The house and concrete will be 4 years old this summer. I have never had this type of concrete treatment in other homes and do not know how to maintain it.
For instance, the original, clear, sealer has deteriorated a bit and now has a non-glossy finish in areas exposed to the sunshine here in NV. My instinct is to first pressure wash the entire drive and patio, let it dry, and then roll on some kind of clear sealer to get the gloss back. Is that the proper way to do it? What types of clear, glossy, sealers are recommended?
