Tub walls and tub enclosures

Tub wall surround application

wedi Building Panels are the natural choice for use with tub walls and tub enclosures. The panels can be installed directly to framing or over gypsum, cement or wood underlayment products to create a waterproof underlayment for tile. They can be easily scored and shaped to provide radius surfaces on tub skirts and do not scratch tubs or fixtures during installation. Additionally, the dimensions of the wedi Building Panels make for quick installations with standard tubs – laid horizontally the panel will span the full five foot width. Cut out a notch at the bottom edge of a wedi Building Panel and safely connect to a tub flange with just a bead of wedi joint sealant in between to safely waterproof this critical connection and create plumb walls, square wall corner areas as well as a full backing for the tile all the way down to the tub's horizontal perimeter area.

Step 1

Measure and cut wedi Building Panel to fit the 450 mm apart framework (wood or metal). Notch out all panels if installed around the perimeter of a flange tub to integrate the flange and achieve a plumb wall with square and tight corners.

Step 2

Attach a notched panel to the framework with a 10 mm' bead of wedi Joint Sealant between the notch and flange. Attach the panel to the framework using wedi Washers and Screws at a rate of 1 every 300 mm along the studs. Leave a gap of 4 mm between tub edge and wedi panel bottom end to allow for movement of the tub. Alternatively apply a bead of wedi Joint Sealant in between both materials.

Step 3

Apply a continuous 10 mm bead of wedi Joint Sealant on the top blue foam edge of the wedi Building Panel before installing the next panel, butting tightly into the sealant. Set another wedi Washer and Screw into the seam to create a flush transition between panels and smooth over excess sealant. When installing a wedi side panel against the already fixed wedi back wall, ...

Step 4

... apply a continuous 10 mm bead of wedi Joint Sealant vertically on the back wall wedi panel where both panels will meet. Apply compression to the wedi Joint Sealant when moving the wedi side panel into position before fastening it. Finally and after all wedi Building Panels are installed a second 10 mm bead of wedi Joint Sealant is applied over all seams and fastener points and spread flat using a putty knife.
