The art of concrete acid stain is that no two slabs will ever color exactly the same. The texture of concrete, age and dilution ratio affect final color appearance. The translucence of concrete acid stain also allows the many unique characteristics of the slab to show through. Every project is a unique piece of art. Sealers and concrete condition will dramatically affect the final outcome of concrete acid stains. Conduct a test on your slab prior to application. The samples displayed are a representation only and do not guarantee the final color to be an exact match. This product may only be used on fully cured concrete. Allow a minimum of 28-45 days of cure time after the concrete placement to allow ample time for the concrete to completely hydrate.
