Abstract
A flooring system including a finished flooring layer and an overlayment to which the finished flooring layer is coupled. The overlayment has a closed cell foam layer, an adhesive layer applied to a side of the closed cell foam layer, and a peelable layer removably positioned on the adhesive layer. The adhesive layer having a positive coefficient sheer adhesion to the finished flooring layer over a period exceeding three weeks from application of the finished flooring layer to the adhesive layer.
Claims8
An overlayment for application of a covering layer thereover, comprising:
- a closed cell foam layer;
- an adhesive layer applied to a side of the closed cell foam layer;
- and
- a peelable layer removably positioned on the adhesive layer, the adhesive layer having a positive coefficient sheer adhesion to the covering layer over a period exceeding three weeks after the peelable layer is removed, the positive coefficient sheer adhesion being at an elevated temperature of 150 degrees Fahrenheit, wherein the positive coefficient sheer adhesion at the elevated temperature of 150 degrees Fahrenheit is higher than if the overlayment was not at the elevated temperature.
