This product is a unique decorative finish that gives a marble-like look to interior and exterior concrete. Formulated with Bond-Lok technology to transform the surface to the warm earthtones historically associated with rich, old world floor design. Must be top coated with either Valspar Etching Stain Sealer for exterior use or Valspar Premium Clear Coating for interior use. Use on interior concrete floors, patios, sidewalks, driveways, and garage floors. Dries to touch in 4 hours, wait 24 hours before washing off etching residue, let dry then seal with clear coat mentioned above. Concrete must have cured at least 28 days prior to staining. Previously coated surfaces should be stripped and tested for beading before applying this stain. Apply with low-pressure sprayer, mop, or brush. Follow safety precautions on label. Clean up tools and materials with solution of 1 lb. baking soda to 2 gallon of water.
