Extending the WEDI Fundo Shower Pans

WEDI offers a presloped extension panels that can be connected to the WEDI Fundo Shower Pan using a shiplap notch which is prefabricated into the extension panels. When panels are cut, the shiplap connection field cut [circular saw and utility knife] into the panel. WEDI Joint Sealant is then used inside the shiplap joint and an additional bead is applied on top of the joints with a putty knife to smooth the sealant over the joints and create a waterproof joint.

WEDI requires the use of a proprietary sealant, engineered for flexibility and waterproofing.

Note – for accessibility issues, the WEDI Lingo is a curb-less, sloped shower base ¾ inches thin at its perimeter and available in various sizes
