time required for an adhesive to achieve its initial tack before the floor covering is laid on top |
Underlay |
a board laid on top of the subfloor to provide a smooth, even surface for the floor covering to be installed on top |
Underlayment |
a smoothing compound or levelling compound applied to the surface of the subfloor to provide a smooth, even surface for the floor covering to be laid on top |
Undulations |
wave-like ridges and troughs in the floor surface |
Wear layer |
surface of a resilient floor covering that protects the pattern and design |
