happy holidays to everyone.
I was asked by one of my commercial (restaurant) customers to clean and to re-stain concrete inside patio. They specified acid stain and a sealer. I have never done acid staining before. Is this something that I can done myself or need to hire concrete refinishing contractor?
I am very handy and the concrete is brushed finish. Can somebody explain to me how is acid staining done and what should I be aware of. should I also strip previous stain?
