Acid-stained concrete (also known as acid-etched concrete) is an economical and attractive way to renovate a retail space floor.  Exciting color choices create a one of a kind acid stained concrete floor which are durable and easy to maintain. Dry mopping and occasional waxing have kept these floors at Rising Tide Tattoos in Boulder, CO and In-Step Footwear in Boulder, CO looking new, even after a few years of use. Decorative concrete is a great option for commercial floor space that requires durability and beauty.
