The 600 sq. ft old concrete patio was aged 30+ years. The slabs were not poured at the same time and the texture was also different. One slab was significantly more porous than the other. Neither slab could be acid stained successfully so a topical stain was selected. Liquid Colored Antique is an excellent stain choice when acid staining isn’t an option. It’s quick and easy to apply requiring no after-application cleaning. The homeowner wanted a more solid but not opaque color. She selected the Liquid Colored Antique in Driftwood. The patio was power-washed first to remove loose debris and paint but some rust staining and paint residue remained. Two coats of liquid colored antique and sprayable satin finish sealer were applied using a fence and deck sprayer. The project was easy to do and fast to finish with very positive results. The homeowner couldn’t have been more delighted.
