Use of sealing membranes
Sealing with wedi Subliner Dry
wedi Subliner Dry is a thin-layer, crack-bridging sealing membrane that ensures excellent adhesion of tile-setting compounds thanks to its special fleece layer on each side, guaranteeing a minimal increase in floor build-up. This product is particularly suitable for ceramic tiles and slabs and for natural stone cladding for internal walls and floors to provide quick sealing for projects with a tight deadline.
Step 1
Lay out wedi Subliner Dry and cut by using a cutter or scissors.
Step 2
Apply thin-bed mortar to the prepared subfloor using a 4 or 6 mm toothed trowel.
Step 3
Insert wedi Subliner Dry with the printed side facing upwards and press on with a rubber roller or wooden board.
Step 4
The widths must overlap at the joints by approx. 5-10 cm. Apply cement-based slurry-type sealing compounds to the overlapping area.
Step 5
Insert the second width and press on the overlapping area using a trowel or rubber roller.
Step 6
Seal off corner joints and floor connections with wedi sealing tape and cement-based slurry-type sealing compounds. Apply the sealing tape in the middle of the joint.
Step 7
The floor covering can be laid after the thin-bed mortar has hardened.
