wedi Fundo  Sloped Straight Extensions

1. wedi Fundo shower base is installed first. Determine measurements for the extended shower area. In this example, we are

extending the shower area in one direction only using our extension panel.

2. Cut the extension panel to size using a circular saw or handsaw and dry-fit the extension panel to the shower base‘s

perimeter channel. The extension panel features pre-made channels 1/2 in. deep and 1/2 in. wide, to connect to the shower

base, as well as channels on its top surface perimeter where wedi Building Panels (at a wall transition), or a curb can be

connected safely.

3. If additional channels are needed after cutting to size, these can be re-made and cut out using a circular saw and / or a

utility knife.

4. A ½” bead of wedi joint sealant is continuously applied on the horizontal and vertical surface area of the Fundo base

channel.

5. Apply a modified thinset bed on the subfloor as well as on the underside of the extension using a 1/4 in. x 1/4 in. square

notch trowel on each surface. Make sure the mortar does not contaminate the joint sealant.

6. Install and press the extension panel into the thinset bed and let it connect tightly into the channel connection of the Fundo

shower base. Use a flat putty knife to spread all excess joint sealant flat over the connection seam.

7. Finally, a continuous ½” bead of wedi joint sealant is applied over all surface connection joints and spread over the joints

using a putty knife.

8. Weights are applied equally over the shower floor to promote a firmer bond with the thinset mortar allowing you to

continue working on the shower walls immediately.

9. The installation can now be completed using wedi Building Panel for walls and wedi curbs to separate the sloped shower

floor from the flat bathroom floor.

10. The shower unit is ready for tiling. Please consider and plan for the tile cut and grout line design. The shower base features

slope fields that direct water to the drain from all sides, while the extension surface provides one sloped direction. For

tile size recommendations and other post installation considerations please review the applicable Primo, Ligno, or Riolito

Installation Manual, which applies to the extended shower floor area as well.
