ENDURANCE Ultra is a 25% solids acrylic copolymer metal-crosslinked floor finish designed for ultra high speed (UHS) burnishing once a week, or less. Endurance Ultra provides excellent initial gloss, excellent durability, and great burnish response. Endurance Ultra can be used on resilient tile (vinyl, linoleum, and rubber), and terrazzo. Endurance Ultra acts as an excellent topcoat for most non-resilient surfaces (unglazed quarry tile, and unglazed ceramic). Endurance Ultra resists scuffing and black heel marks while retaining its appearance between burnishing intervals.
