wedi Nonstep Plus impact sound deadening for rigid, level substrate is made from 6 mm recycled rubber material and XPS flakes bound with polyurethane. It is adhered to a 6 mm wedi building board to produce a ship-lap joint connection. After all-over reinforcement with wedi Tools reinforcement tape, tiling can be carried out directly onto the board without any other preliminary treatment. There is just one exception; if the floor is uneven it should first be levelled out using suitable fillers. The improvement in impact sound deadening under ceramic floor overings is 16 dB.
Step 1Before laying-up apply a perimeter isolation strip all around. Level out any unevenness of surface before laying.
Step 2Install the impact sound-deadening boards. Avoid cross joints.
Step 3The entire board surface area is then reinforced with wedi Tools reinforcement tape and fixed in place in a layer of tile adhesive, making it ready for tiling. Alternatively, in wet areas, the seal can also be carried out with wedi 610 or wedi Tools sealing tape.
