PUM-955 Ultra-Nail®

STAUF PUM-955 is a urethane-based, high-strength adhesive for professional wood flooring installation. It does not contain isocyanates, any solvents, or other hazardous materials. It is, therefore, ozone and environmentally safe. PUM-955 spreads easily with a specially designed gun and has a non-slump formula to allow the ridges to bridge gaps between wood floor and the subfloor. Beads are spread approx. 3 inches apart on the subfloor. Vary the height of beads to eliminate hollow spots especially when installing long planks. Since there is no water or solvent present it will not cause dimensional changes to wood flooring. PUM-955 was designed for an easier installation of long planks on uneven or unstable subfloors instead of nail-down installation and allows for the natural movement of the floor. It can also be used to glue wood molding. 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 flash 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.
