wedi Fundo  Installing Sloped Extensions across shower base corner

1. wedi Fundo shower base is installed first.

2. Determine the measurements for the shower area to be extended. In this case, we will extend the shower area on two sides.

3. Measure, cut and dry-fit two extensions so they can be abutted along a 45 Degree corner seam.

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

perimeter channel and so they can join butted tightly at the corner. The extension panel feature 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. 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.

5. Turn both extensions on their back and cut a 1/2 in. x 1/2 in. notch channel into each extensions edge where both

extensions connect. Make and dry-fit a strip of 1/2 in. Building Panel into the 1 in. x 1/2 inch channel formed by

the two extensions where these join.

6. Apply 1/2 in. beads of wedi joint sealant along the edge of both extensions where these later connect.

7. Join both extensions and press these together tightly and keep pressure on the panels so the sealant can initiate

its curing process under pressure for at least 30 minutes.

8. Apply two 1/2 in. beads of wedi joint sealant along and inside the channel.

9. Insert the 1/2 in. wedi Building Panel strip. Make sure the strip is shaped to fully align with the channel shape.

Where the extension connects the the shower base corner, this strip will need to show a V cut. On the other side

of the strip on the exterior corner, it will have the shape of a pointed arrow. Apply a final seal of wedi joint sealant

over the seamed area and cover it widely and 1 in. beyond all seams.

10. Allow the extension to cure for at least 30 minutes.

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

base channel.

12. 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.
