Alternatively, wedi sealing tape can be used instead of the wedi Joint
Sealant and applied in modified thinset. The sealing tape provides ad-
equate splash water protection but should not be used in areas with
constant wetness/ water exposure, because thinset mortar might allow
pressing water to migrate underneath the sealing tape through the
thinset mortar. If you use wedi Building Panels with wedi Shower
Bases, wedi Joint Sealant must be used in-between seams and on top
of seams. No sealing tape is required in these applications. Please con-
sider: sealing tape is installed in cement based thinset and can allow
pressing water to migrate under the tape. The thinset holding the tape
can also not provide protection against movement. Both challenges are
addressed more efficiently by using wedi Joint Sealant. In dry areas,
the seams can be treated with an alkali resistant fiberglass mesh tape
by wedi.
Where wedi Building Panel transitions to drywall panels, wedi reinforc-
ing tape, or sealing tape or wedi Joint Sealant may be used. The drywall
surface should be primed. Conversely, if mesh and gypsum plaster is
used over such seams in dry areas, the wedi Building Panel surface
must be primed.
A continuous 1/2” (12.7 mm)
bead of wedi Joint Sealant is
applied on the foam edges of
a wedi Building Panel before
another panel is joined by
butting tightly.
Apply 1 wedi fastener per
every 12” (304.8 mm), with an
extra fastener applied directly
in the seam to provide a flush
transition between panels. On
a ceiling, apply 1 wedi fastener
per every 6” (152.4 mm). The
washer heads are dimpled
below the surface of the wedi
Building Panel so a flat surface
is maintained.
All excess wedi sealant is spread
flat over all joints using a putty
knife. Where needed, an extra
bead of sealant is applied on top
of the joints and spread flat. The
joints should be covered a full
1”
(25.4 mm) on both sides of
the
seam. Especially wedi Joint
Sealant
provides little build-up
making for square and tight
cor ner areas perfect for tiling.
All fastener locations are wa-
terproofed using wedi Joint
Sealant spread flat and widely
over each washer.
