Specialty Applications – the wedi Building Panel as solution
Building Custom Seats and Benches Using 1 1/2“ (38.1 mm) or 2“ (50.8 mm) thick
wedi Building Panels
Measure and cut the bench pieces off a wedi 2” (50.8 mm) thick
Building Panel and dry fit. When installing a corner seat, the panel
edges are mitered for a tight fit. To achieve a slope, the part’s upper
ends are cut down with a slight angle towards the front of the bench.
Optionally, create a pitch using wedi Joint Sealant as a “wet shim”.
The wedi parts are adhered to the wall using thinset mortar or wedi
Joint Sealant. Adjoining parts are glued together using wedi Joint
Sealant continuously applied along all foam edges of a panel part.
Excess is spread flat over the seams using a putty knife. Where the
part’s backs meet the wedi wall, modified thinset mortar is used in
a full contact surface bed. Once the bench is built, a final bead of
wedi Joint Sealant is applied to safely seal all seams to the wedi wall.
The vertical front part of the bench will show a small gap to the pit-
ched floor. Please fill with thinset mortar and alkali resistant fiberglass
mesh tape by wedi, applied over this seam. Alternatively, benches and
seats are offered as prefabricated units made by wedi. For longer or
larger benches built from our 2” (50.8 mm) building panel, always in-
stall one spacer/support made of wedi 2” (50.8 mm) Building Panel
every 18” (457 mm) in either direction. Over blue exposed foam edges
please adhere a wedi Building Panel strip to foam using wedi Joint
Sealant. This will create a cement based surface to adhere tile to it.
Optionally, the blue foam may be covered with wedi Joint Sealant. The
covering of the blue foam areas is not necessary, where tile is used that
will overlap and cover the blue area with no more than 50 % of its size.
Such larger tile is thinset adhered to seat including the foam surface.
The maximum weight allowance on seats or benches built with vertical
supports placed every 18” (457 mm) o.c. is 500 lbs (227 kg).

Installation on tub walls
Measure and cut wedi Building Panel to fit the 16” (406.4 mm) o.c.
framework (wood or metal). Notch out all panels if installed around the
perimeter of a flange tub to integrate the flange and achieve a plumb
wall with square and tight corners.
Attach a notched panel to the framework with a 1/2” (12.7 mm) bead
of wedi Joint Sealant between the notch and flange. Attach the panel
to the framework using wedi Washers and Screws at a rate of 1 every
12” (304.8 mm) along the studs. Leave a gap of 1/8” (3.2 mm) bet-
ween tub edge and wedi Panel bottom end to allow for movement of
the tub. Alternatively apply a bead of wedi Joint Sealant in between
both materials.
Apply a continuous 1/2” (12.7 mm) bead of wedi Joint Sealant on the
top blue foam edge of the wedi Building Panel before installing the next
panel, butting tightly into the sealant. Set another wedi Washer and
Screw into the seam to create a flush transition between panels and
smooth over excess sealant. When installing a wedi side panel against
the already fixed wedi back wall, apply a continuous 1/2” (12.7 mm)
bead of wedi Joint Sealant vertically on the back wall wedi Panel where
both panels will meet. Apply compression to the wedi Joint Sealant
when moving the wedi side panel into position before fastening it. Fi-
nally and after all wedi Building Panels are installed a second 1/2” (12.7
mm) bead of wedi Joint Sealant is applied over all seams and fastener
points and spread flat using a putty knife. On tubs or trays without or
only partial nailing flange, use also wedi's tub sealing tape with its Butyl
waterproofing strip.
