Concrete patch and repair products that can be purchased in stores are usually Portland cement based products. They are either troweled or brushed onto your current concrete surface. They form a mechanical bond to your existing surface that still allows salt, freeze and weathering damage to occur. Over time the surface will delaminate. New Castle Artisan products are composed of acrylic cement blended with polymers which form a stronger bond with any porous surface. Combined with an occasional protective sealant coat, we confidently offer a two-year warranty against peeling, flaking or delamination.
