With Sticky-Bak adhesive stencils, contractors can make concrete look like stone, tile, or brick—without the higher costs associated with those materials. Made of a high-strength, flexible material, the non-residue stencils work successfully in troweled-down and vertical overlay applications. They do not lose their form and are water impermeable.
