Step 1: Cut the Panels

Cut all of the panels to size, and lay them out as you want them before gluing any of the panels down.

Step 2: Cut the PEX Pipe and Secure

Cut several 12 inch pieces of the PEX pipe, and lay out the panels. Start at the longest wall.

Insert a piece of the PEX into the track to ensure that the panels are aligned. Use a rubber mallet to help secure the PEX into the track.

Step 3: Cut the Panels and Fit into Place

Continue fitting the panels and securing them with the PEX. Mark the panels that need to be cut, and use a circular saw to make the cuts.

When making a filler piece, make them as big as possible.

Continue around the room, fitting the panels into place.

Note: Use tile setters between each panel to create a 1/8 inch gap to allow for expansion.

Step 4: Glue the Panels

Glue each panel down starting in the corner of the room. Apply the adhesive to the back of each panel in the center and along all four edges. Be sure to apply an even bead of adhesive on the tiles.

Step 5: Place Tile Spacers Between Panels

Place the panel into position, and place a tile spacer in between the panels. Screw the panel into place.

Remove the next panel, and apply the adhesive. Insert the spacers and reinsert the short piece of PEX into the track to further ensure alignment.

Step 6: Screw Down the Tile

When the tile is positioned, screw it down. Use at least 10 screws on a full panel.
