If the floor covering being renovated is slightly uneven, wedi Nonstep Plan is the product you need. The impact sound deadening board is made from recycled rubber material and XPS flakes bound with polyurethane, which is coated with a special flexible mineral sealing slurry. You can tile straight onto wedi Nonstep Plan once it has been fully reinforced with wedi Tools reinforcement tape. You only need to level out areas which are particularly uneven beforehand. The improvement in impact sound deadening under ceramic floor coverings is 14 dB.
Step 1Apply a perimeter isolation strip all around. Even out any rough unevenness before tiling. It can be cut simply using a carpet cutter.
Step 2Seal the joints with masking tape to prevent acoustic bridging.
Step 3aApply the tile adhesive over the whole surface as a bonding layer. Lay the wedi Tools reinforcement tape into the tile adhesive with an overlap of 5 – 6 cm and bed it in with the trowel. It can then be tiled.
Step 3bIf the area is to be sealed, the board joints should be covered with masking tape. Then, apply wedi Tools sealing tape as well as adhesive to the joints, and then again apply adhesive to the whole area. Then, apply self-adhesive wedi Tools reinforcement tape 600 mm over the entire surface area.
