My previous floor left a sticky glue on the sub-floor. Can I install SnapStone directly over this surface?
A. It is not recommended to install SnapStone directly over glue for three reasons: 1) Without knowing the composition of the glue, there could be an interaction between the polymer tray and the glue. 2) It may be difficult to properly install the SnapStone over a sticky substance since the installation method requires the tiles to interlock while flat. 3) Since the floor is designed to float, you might hear the tile “sticking” and “unsticking” to the glue below when you walk on it. Instead, you may consider installing a thin underlayment (1/8″) over the floor, giving you a smooth sub-floor for installing your SnapStone floor.
