wedi Subliner Dry & Flex is an all-in-one sealing and decoupling solution. It is a flexible, crack-bridging sealing and decoupling membrane with special layer of fleecing material on both sides, providing optimum anchorage for tile laying materials. It 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. The special membrane provides improved tension compensation, even if sudden temperature changes occur.
Step 1Lay out wedi Subliner Dry & Flex and cut by using carpet cutter or scissors.
Step 2Apply wedi thin-bed mortar onto prepared surface, using 4 mm or 6 mm groove.
Step 3Place wedi Subliner Dry & Flex edge to edge – with the printed side facing upwards – and press by using a rubber roller or wooden board.
Step 4Remove any escaping mortar and/or air bubbles. Do not overlap.
Step 5In the joint area, apply wedi sealing tape over the joints, embedded in a layer of cement based adhesive in order to ensure waterproof sealing. Press over the joint area by using trowel or rubber roller.
Step 6Apply wedi sealing tape and cement sealants (for outside) to corner joints and floor connections to ensure sealing. Centrally apply sealing tape onto joint.
Step 7The floor covering can be installed after curing of the thin-bed mortar.
