VIVID Acid Stain colors concrete surfaces with a beautiful variegated and mottled appearance. VIVID Acid Stain can transform an ordinary concrete surface into the rich look of granite or marble. Reacts with minerals that exist in concrete that has cured for at least 28 days. It penetrates the very top layer of the concrete surface with color that will not chip, crack, or peel. The colors produced in each section of concrete will be unique with captivating, multi-colored intensities that become a permanent part of the concrete. **PLEASE NOTE** – Due to the nature of this and all acid stains, color cannot be guaranteed. There are thousands of variables at play in the concrete, therefore, the acid stain will produce a completely unique color on each individual surface. This unique look is one of many design benefits of acid stains. However, it is HIGHLY recommended that a representative sample be performed on the actual surface to which the stain will be applied to determine suitability and color.
