Fill unused Ligno perimeter channels by sealing in wedi Panel strips
(included in box). Prepare to install wedi Subliner Dry waterproong
membrane over the suboor outside the shower and reaching 4”
(101.6 mm) into the Ligno and going up at walls at least 2” (50.8 mm)
(ashing) by applying modied thinset
using a 1/4 × 1/4 ” (6.4 × 6.4 mm)
notch trowel. The area to be so waterproofed starts 4 ” (101.6 mm) into
the Ligno and extends at minimum 3 ft. (914.4 mm) outside of the shower
or as far as shower/spray water may reach. We recommend to waterproof
the entire bathroom oor as water may spread below tile level and on top
of waterproong.
Apply a modied thinset (ANSI 118.4 or equivalent) across the wood
or cement board oor surface and now apply wedi Subliner Dry Sheet
waterproong membrane overlapping into the Ligno base for 4” (101.6
mm). Apply wedi‘s prefabricated outside or inside sealing tape corners
and sealing tape or Subliner Dry folds as a ashing to the wedi wall
panels/Ligno and Subliner dry sheets as applicable. Install this water-
proong system over the oor substrate outside the shower. All areas
subject to water splashes and spray must be waterproofed. wedi re-
commends to waterproof the entire bathroom oor (including a as-
hing up into the wall at least to the height of a regular base board or 2“
[50.8 mm] high) in spaces where curbless showers are being installed.
Subliner Dry sheet waterproong membranes are installed to the ap-
plicable surfaces using thinset mortar All overlapping seams between
Subliner Dry to wedi Fundo or Building Panel, and between Subliner
Dry sheets are sealed with a full bed of wedi Sealant 620 for a width of
2“ (50.8 mm). All Subliner Dry tape and prefabricated corner tapes are
fully embedded and installed using wedi Sealant 620. The wedi Sealant
620 can be installed once the thinset mortar below the membrane has
cured. ( see also installation manual wedi Subliner Dry). Your shower is
ready for tile once wedi Sealant 620 is dry to the touch. Alternatively
to Subliner Dry sheet membrane system wedi Building Panels in 1/4”
(6.4 mm) or 1/2” (12.7 mm) and 3/4“ (19 mm) thickness (3/4“ [19
mm] panel if no recess of base and base connected to wedi Panel with
a Z notch connection in the panel connecting to Ligno base‘s channel)
can be used as the oor tile underlayment in lieu of cement board and
Subliner waterproong. wedi Building Panel would be installed over
wood oor suboor and overlap and seal into the Ligno channel. In
such application the Ligno base must be raised to allow its channel to
fully stick out from the recessed area so wedi Floor Building Panels can
be interlocked with its channel. All seams to wedi walls or Ligno base
are sealed internally with wedi Joint Sealant, and are covered with an
external 1/2” (12.7 mm) bead of wedi Joint Sealant spread at. Your
shower is ready for tiling once thinset under wedi Subliner Dry or wedi
Building Panels on oor has cured.
