wedi Fundo  Adding a second or more straight extension in line

1. Determine measurements for the next extended shower area. In this example, we are extending the shower area in one

direction only using our extension panels to connect to a previously installed extension panel. In this way, wedi Fundo

shower bases can be extended indefinitely. Please note that all added extensions will increase the height of the construction

from the floor through the slope built into the extensions.

2. Usually, this requires adding additional wedi Building panels of the thickness types 1/8 in. , 1/4 in. or 1/2 in. to build up

the added extension for a tight fit. Panels may need to be combined and multiple panels are adhered using a full surface

contact bed of thinset mortar applied using a notch trowel between 1/8 in. square to 1/4 in. square. Please dry-fit this build

up and consider the thickness of mortar to be added.

3. Apply a modified thinset bed on the subfloor using a 1/4 in. x 1/4 in. square notch trowel. Make sure the mortar does not

contaminate the joint sealant.

4. Place the wedi Building Panel into the thinset bed.

5. Apply a modified thinset bed on the Building Panel using a notch trowel.

6. A 1/2 in. bead of wedi joint sealant is continuously applied to the horizontal and vertical side of the extension panel already

installed on the floor.

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

Fundo shower base.

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

9. 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.

10. 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.

11. 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.
