wedi Tub Sealing Tape with waterproof Butyl connection strip for waterproof
connections between tubs/trays without nailing flange and wall assemblies
Ensure the installation site is
clean, and all structures are even,
plumb, square and load bearing.
Install 2 × 4 blocks between
studs on all sides where tub or
tray meet framing. The bottom
edge of the 2 × 4 block is at the
height of the top edge of the tub
or tray.
Move tub or tray into its final
position and push tight against
the framing.
With all panels installed, seams and fasteners sealed, the installation is
complete fast. Please note, the Tub Sealing Tape is a secondary line of
waterproofing. This may become important with tubs or trays which have
no nailing flange and may flex and move a lot, not only due to extreme
temperature changes. The tape will be there should your wall waterproof-
ing ever be compromised due to such extreme tear and wear due to
flexing or movement of a tub or tray.
Dry fit the length of the wedi
tape needed to cover all three
sides of the tub or tray. Then re-
move the protective cover from
the butyl strip in several steps as
you work your way around the
tub. Press the butyl firmly to a
clean and grease free, vertical
top area of the side of the tub
or tray.
Ensure the tape is now pressed
into the beads of wedi Joint
Sealant and pressed flat over
the
2 × 4 blocks. A putty knife
will help you with this step.
Cut off any tape exceeding the
three sided perimeter of the tub
or tray.
When ready for the wedi Build-
ing Panel installation on the
walls, apply a 1/2” (12.7 mm)
bead of wedi Joint Sealant along
the tubs outer edge where the
first wedi Building Panel will
connect to the tub or tray.
Apply two continuous 1/2”
(12.7 mm) beads of wedi Joint
Sealant low and centered along
the 2 × 4 blocking. Apply on all
three framed sides. Note, the
working time of the sealant is
appr. 10 minutes, depending
on the site’s climate.
Install the wedi Building Panel
as explained in wedi installation
guidelines for wet area walls.
When installing wedi building panels or conventional wall backers to
a tub, there may not be a tub flange to safely connect and seal to. For
these cases, wedi developed a special sealing tape to add protection
in an application where movement of the tub may, over time, breach
a butt joint between a backer board and the tub itself. If that hap-
pened, the wedi tub sealing tape is still there to form a second line
of defense to keep the water safely away from reaching the framing.
