Can NuCore be installed over existing flooring?
- Concrete: Do not use planks as a moisture barrier. Concrete subfloors must be fully cured and should have minimum 6 mil (0.15mm) poly-film as a moisture barrier between the concrete subfloor and the flooring.
- Tile: Make sure to level out your tile floor. If clicks overlap a grout line it may compromise the integrity of the click system, fill up grouts wider than 1/8" with a leveling compound when installing over tiles
- Wood: Be sure that wood floor is flat and stable. If noisy planks are present, fix them before installing the floor.
