Simply spread modified thinset
mortar over a clean wood sub-
floor using a 1/4” × 1/4“ (6.4
× 6.4 mm) notch trowel pro-
vided the subfloor is even and
load-bearing.
Apply the wedi Building Panel
by laying the panels into the
mortar. Stagger all panel joints.
Apply weights, such as tile
boxes, equally across the wedi
Building Panel surface and es-
pecially over transitions.

Fasten with wedi Fasteners.
Use wedi Tabless Washers and
wood screws.
Tape all joints with wedi fiber-
glass mesh tape in dry areas
or
wedi Joint Sealant in wet areas.
Fastener locations should be
waterproofed too using wedi
Joint Sealant. Begin tiling once
tile adhesive has cured below
wedi Building Panel.
wedi Building Panels over Wooden
Subfloor Installation
All wedi Building Panel sizes and thicknesses can be used as tile under-
layments over wood subfloors. A modified thinset mortar is applied to
the floor with a 3/16“ (4.8 mm) to 1/4“ (6.4 mm) square notch trowel
to provide a ribbed bed. The wedi Building Panels are then laid into
the mortar. All joints should be staggered so that no seam continues
throughout the length of the floor. wedi fasteners, in this application
tabless washers and wood screws, are applied every 1 ft. into seams to
create flush transitions between panels making use of the wedi washer
and are generally set at a rate of 1 fastener per 1 square foot across
the panel surface. All seams should be taped with wedi alkali resistant
mesh tape in dry areas or with wedi Sealing Tape or wedi Joint Sealant
in wet areas. Fastener points are waterproofed using wedi Joint Sealant
before tiling begins once the thinset mortar has set up below the wedi
Building Panels. Use weights over wedi Building Panels and especially
across panel transitions to ensure full bond and smooth transitions.
Extend your waterproofing
from shower and tub areas into
the whole bathroom with wedi
Building Panels or the wedi
Subliner Dry Sheet Membrane
system on your floor. Espe-
cially when installing floor
level
entry showers, a waterproof tile
underlayment is needed
in the
front of a shower entrance.
wedi Building Panels and wedi
Subliner Dry can help you
create both in one step: your
waterproofing and tile under-
layment as well.
