How to install wedi Prefabricated
Shower Seats and Benches
(Prefabricated and field fabricated)
Triangles made from wedi 2” (50.8 mm) Building panel may be used to con-
struct and install tile ready, suspended corner seats. The wedi Building Panels
may be single sheets or doubled up to 4” (101.6 mm) or more by adhering
several triangle cut wedi 2” (50.8 mm) Building Panels using full contact appli
-
cation of a minimum 1/4” × 1/4” (6.4 × 6.4 mm) square troweled bed of mod-
ified thinset mortar or wedi Joint Sealant equally applied to the surface in 1/2”
(12.7 mm) thick beads. The triangle seats are then sealed and adhered against
wedi wall Building Panels using wedi Joint Sealant applied in 1/2” (12.7 mm)
beads equally distributed over the contact surface. The seats should be pressed
into position giving it no more than 1/8” (3.2 mm) of a slope to the front. The
seats have to be kept under compression against walls for at least 20 minutes.
More joint sealant is then applied in 1/2” (12.7 mm) beads over all seams top
and bottom of the seat and troweled flat using a putty knife. Once the joint
sealant has developed a skin after appr. 20 – 30 minutes, wedi mesh tape is fi

nally applied in modified thinset mortar over these seams. The seat is now ready
for tiling. Please note that the maximum seat size in this shape is limited to
18” seat length at both connecting (90° corner-) walls. Such field constructed
triangle seats are approved for live and dead load of 250 lbs centered on the
seat. Below you can see the installation of wedi‘s prefabricated triangle seats.
They are designed to withstand a weight of up to 350 lbs centered on the seat.
