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 pan-
els/Ligno and Subliner dry sheets as applicable. Install this waterproof-
ing system over the oor substrate outside the shower. All areas subject
to water splashes and spray must be waterproofed. wedi recommends
to waterproof the entire bathroom oor (including a ashing 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 applicable
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.
