wedi Drain Cover Assembly / Insertion
Insert Cover frame into base hole (no glue / no screws). You may caulk between part and tile to create a flexible grout joint. Optional Extension Collar
can be cut to height if part is needed. The caulk joint must not create a water barrier damming up the water draining through the thinset bed into the
drain from below the tile. Therefore the thinset layer must be continuous toward the drain. Use the black plastic extension collar if you need to raise
the wedi frame and cover. Cut extension collar to size and insert below the frame/cover. If not needed, the extension collar may be disposed of as it
is not necessary for the functioning of the wedi installation. Use the black plastic extension collar if you need to raise the wedi frame and cover. Cut
extension collar to size and insert below the frame/cover. If not needed, the extension collar may be disposed of as it is not necessary for the functioning

After Installation
All visible joints or seams in the installation are visibly covered and reinforced with wedi joint sealant applied flat over the seams. Coverage of wedi joint
sealant over all seams should be at least 3/4-1 inch on either side of the seam. The joint sealant should be no less than 1/16“ thick for strength. Do not add
mesh tape into the wedi joint sealant. This may only put the waterproof performance at risk and will not strengthen the system‘s resistance against movement
related stresses. Once wedi joint sealant application over all shower system seams has been completed, a water flood test may be performed as early as
2 hours later, provided a temporary dam has been built for this curbless shower. No premixed organic mastic adhesives are used with wedi systems when
installed in wet areas. Ceramic tile smaller than 2 x 2“ are not used within wedi Fundom Ligno. Tiles in Ligno showers used for wheel chair accessibility
require adhesion in epoxy thinset mortar and grouting using epoxy grout. Non square tiles must be set accordingly and the shortest side of the tile
determines the appropriate setting materials. Larger format tile > 4 inches square may be used on wedi Fundo but have to be cut. They have to be cut
for their grout joints aligning with the wedi shower base slope lines (where slope fields meet).
