READ this entire installation guide before beginning your installation. The manufacturer is not responsible and will not be held liable for project failures if installation guidelines are not followed.

Although these tiles are 100% waterproof, we recommend the use of a siliconized sealer like DAP® or SilTex in the seams for added protection. Follow your local building codes for wet environments like shower and tub enclosures. We recommend a 100% waterproof substrate that will prevent water from getting behind potentially unsealed areas that would cause mold or other damage.

Acceptable waterproof substrates: existing ceramic tile walls, CementBoard ® , Schluter Kerdi Board® , GP DensShield® , Johns Manville GoBoard® ,HardieBacker® , Fiberock® and equivalent products. Always follow manufacturer's installation instructions to create a waterproof enclosure

Use the sub-deck screws by placing them into the pre-drilled countersunk holes so that the screws can be flush with deck surface.

Dry fit the bench for 2 reasons. The first is to see what side you prefer since the pattern will vary on each side.

The second reason is to make sure it fits well against the wall on both sides, If not, you might have to plane and/or sand edges to adjust the fit. Use a plane and/or sand to adjust the fit. Keep in mind you will need to adjust both the top and bottom of the bench.

As you get closer to it being all the way in place, the sealant should start to push up to fill in between the wall and bench edge.

Wipe off any excess sealant that pushes out or add sealant in areas needed.
