White Mountain Ultrapel™ is an invisible, stain-blocking sealer that locks out oil, grease and other organic stains from concrete, masonry and tile. Designed for use in dining, food service areas and parking facilities, Ultrapel makes no appreciable change in the appearance of most surfaces. Effective on interlocking concrete and clay pavers, colored and stamped concrete, flagstone and other porous surfaces, Ultrapel can even repel stains such as engine oil, by causing the oil to bead-up and stay above the surface until washed away. If left unprotected, oil and other dark liquids can soak in, permanently staining a paver or porous surface. Protect the appearance of your floor easily with Ultrapel.
