Q: Do I have to leave a full ¼” expansion gap at the base of a tub or shower?
A: No, you can reduce this gap to 1/8” as long as all the other perimeter gaps have a full ¼” expansion gap. We recommend this perimeter be caulked with silicon to create a water-tight seal.

Q: Can I use the flexible grout at the base of a tub or shower instead of caulk?
A: No, the flexible grout doesn’t create a watertight seal against a tub or shower base due to the movement of the structure. Always use a caulk or sealant where you need a water-tight seal against any perimeter object.

Q: I hear a creaking noise in the plastic tabs after I install the tile. Do I need to do anything before I grout?
A: First, ensure the floor is flat within tolerance, 1/4”-10’ or 1/8”-6’ – excessive movement may cause this noise. If the floor is flat then grouting will eliminate the noise.

Q: Can I install an additional pad under the SnapSys System?
A: No. Unlike other floating floor systems, the SnapSys System has a slip-resistant rubber overmold that will make it very difficult to install over a laminate pad without tearing it. Installing an additional pad will allow the tiles to move more than intended.

Q: Do I need a t-molding transition between rooms?

Q: Can I use the SnapSys System on stairs?
A: While the SnapSys System is sold and warranted as a flooring system, many retailers offer the SnapSys tile designs without the tray for traditional applications such as stairs. However, if the system is installed on stairs, it should be securely adhered using a premium construction adhesive such as PL 400 or PL Premium.
