One of the greatest features of acid-stained concrete flooring is its resistance to wear, tear and decay. Acid-stained concrete floors simply do not wear out. On their surface, they have compressive strengths in excess of 4,500 pounds per square inch, so they are very much unlike traditional floor coverings, which may warp, buckle, tear, scratch, dent, loosen, flake, rot, and grow mold and mildew. Acid stained concrete flooring is also inflammable, and their coloring and finish resists ultraviolet light. When installed properly, acid-stained concrete flooring does not chip, peel, discolor, stain, or fade, like more traditional concrete coatings. What all of this means is that children, pets, guests and customers will have a very difficult time doing any damage at all to an acid-stained concrete floor. As such, acid-stained concrete floors never have to be removed or replaced, and they hardly ever have to be refinished.
