Mapei Ultrabond ECO 570 Premium Urethane Rubber Sports Flooring Adhesive 18.9 L

This is Ultrabond ECO 570 Premium Urethane Rubber Sports Flooring Adhesive, a urethane adhesive for rubber sports flooring. It is for reground rubber sports flooring in mats or rolls and reground rubber underlayment, indoors or out. An 18.9 L pail is roughly 424 to 474 sq ft with a 1/8" U-notch. No flash time. Working time 30 to 60 minutes, with 1 to 2 hours to adjust. One-component moisture-curing polyurethane at 100% solids. It cures permanently. No MVER figure on the sheet. Ambient humidity 20 to 80%, and below 20% the cure stretches out. Light traffic at 12 hours and heavy at 24. It is approved over exterior-grade plywood, concrete cured 28 days, epoxy and cement terrazzo, and levelling compounds. Not over asbestos, not over any adhesive residue including cutback, and not into standing water. It is an adhesive, not a levelling or patching compound. One caution: the data sheet contradicts itself on rain protection, saying 72 hours under Limitations and 24 under Protection. Take the longer figure outdoors. Both the Mississauga and Barrie stores carry it.
