VALSPAR(R) etching stain permanently transforms indoor and outdoor concrete floors to the look of natural marbled stone. Transform your concrete into a custom, marbleized surface like you've seen in your favorite restaurants and stores. Etching concrete stain deeply penetrates concrete, giving a beautiful, stone-textured finish that won't fade, peel or chip. For most applications, VALSPAR(R) etching stain sealer completes the process, bringing out the vibrancy of the color and protecting it from sun, water and household-chemical damage.
