Troubleshooting

Floor feels uneven after installation

Ensure the subfloor was completely level before laying the underlay and flooring. Check for any debris or improperly laid underlay boards.

Excessive noise is still present

Verify that the underlay boards are laid flat and edge-to-edge with no gaps. Ensure the flooring is installed correctly on top of the underlay.

Underlay boards are difficult to cut cleanly

Use a sharp, fresh utility knife blade for cleaner cuts. Score the board multiple times if necessary.

Setup, Compatibility & Care
