Sound deadening underlay boards for rigid sub floors
‘Wedi NonStep Plus can be used on completely level wooden or concrete floors which have been thoroughly cleaned before application.
NonStep Plus is 12mm thick and consists of a layer of Wedi NonStep Plan (as described above) permanently bonded to a 6mm thick Wedi Tilebacker Board, and produced in a manner which provides a ship-lap joint connection.
NonStep Plus delivers a unique combination of impact sound reduction with a completely waterproof substrate, and is especially appropriate in bathrooms and wet areas.
The boards are loose laid in a staggered brick bond pattern utilising the ship-lap joint connection. Then, 60cm wide Wedi TT60 joint reinforcement tape is laid embedded in a layer of cement based adhesive over the whole board area and trowelled smooth. Tiling can commence once the adhesive has cured.
The process described above will achieve a minimum 16db impact sound reduction performance.’
