STAUF PUM-950

Power-Mastic provides a tremendous improvement for urethane adhesives. It is a urethane based, high-strength adhesive for professional wood flooring installation. But unlike other Urethane adhesives, it contains no isocyanates, the primary chemical in other urethane adhesives that will etch fine floor finishes and is a suspected carcinogen.

Long open time allows for easy installations. Since there is no water or solvent present, it will not cause dimensional changes to wood flooring at installation. It has a higher shear strength than competitors, so it grabs, holds and keeps wood floors in place. This adhesive is waterproof when fully cured and will not dissolve if it gets wet. This adhesive has earned the highest GEV-EMICODE EC 1 ranking by the European Association for Control of Emissions for Flooring. See www.emicode.com for information

The adhesive spreads easily and has a non-slump formula that will help insure contact and adhesive transfer. It allows fast installation even with complicated patterns due to its strong green grab. There is no ash time required, so installation can commence immediately. Rolling is neither required nor recommended. It offers superior flexibility and is designed to keep the flooring in place, yet allow for normal movement during seasonal changes to the flooring.
