The Schluter®-KERDI-TUBKIT contains all the components necessary to create a fully waterproof  and vapor tight bathtub surround assembly

The waterproofing is carried to the height of the showerhead (at minimum). KERDI application on the ceiling is optional for bathtub surrounds. The thin-set mortar used for bonding KERDI to walls and ceilings must be appropriate for the substrate and must penetrate and engage the membrane fleece. The mortar must be mixed to a fairly fluid consistency, but still able to hold a notch.

For complete installation guidelines and warranty criteria, please download the Schluter®-Shower System Installation Handbook and view the installation video available below.

1. Clean any dust or other debris from the surface of the solid backing. Dampen particularly dry and porous substrates in order to help prevent premature drying or skinning of the thin-set mortar.

2. Place painter’s tape to protect the tub deck. Apply Schluter SET™, ALL-SET™, FAST-SET™, or unmodified thin-set mortar to the solid backing using a 1/4" x 3/16" (6 mm x 5 mm) V-notched trowel or the KERDI-TROWEL. Completely fill the 1/4" (6 mm)-wide gap between the solid backing and tub with KERDI-FIX or other suitable sealant. Note: When the solid backing is installed above the tub flange, apply KERDI-FIX to the tub flange and spread using a small notched trowel.

3. Apply KERDI-BAND waterproofing strips or 5" (125 mm)-wide cut sections of KERDI waterproofing membrane. Solidly embed the membrane in the mortar and KERDI-FIX to ensure full coverage and remove air pockets.

4. Apply Schluter SET™, ALL-SET™, FAST-SET™, or unmodified thin-set mortar to the solid backing and previously applied KERDI-BAND. Embed the KERDI in the thin-set mortar and work the membrane onto the entire surface to ensure full coverage and remove air pockets.

5. Seams in the membrane are constructed by overlapping the edges of KERDI by 2" (50 mm) or by abutting adjacent sheets of KERDI and installing KERDI-BAND, centered over the joint.

6. Any protrusions through the KERDI membrane (e.g., mixing valve, shower head, etc.) must be sealed with KERDI-SEALPS/-MV, KERDI-FIX, or other suitable sealant.

7. Seal connections to knee walls using KERDI-KERECK-F preformed corners and Schluter SET™, ALL-SET™, FAST-SET™, or unmodified thin-set mortar.

8. Once the entire membrane, including seams, corners, and knee walls have been completely bonded and, therefore, waterproofed, the assembly is ready to be tiled.
