The factory-manufactured fibreglass mesh Kiesel Ki 881 Eco Sound Mesh is an impregnated glass fibre weave. It has been specially designed for renovating residential and commercial buildings to reduce tension and movements in construction. For strengthening composite constructions, for example with:

-     Old tile and natural stone coverings

-     Plaster and masonry

-     Old screed

-     Tile load-bearing elements

-     On wood substrates

-     For thin-layer screed constructions on insulation layers and separation layers

In conjunction with rapid flowable cement screed Servoplan E 600.

For all clean, dry and load-bearing substrates. The substrate must be permanently dry. In individual cases, performing building waterproofing to protect against rising damp from the floor sheet beforehand may be necessary. Any cracks present must be sealed via force fitting.

Lay Kiesel Ki 881 Eco Sound Mesh without creases on sound deadening track Kiesel Ki 880 Eco Sound on a PE foil separation layer or directly onto the substrate and overlap with at least 5 cm. The roll tension should preferably be directed towards the substrate.

In the sound deadening system Kiesel Ki 881 Eco Sound:

After preparation work is completed, the flowable cement screed Servoplan E 600 is installed. Servoplan E 600 must be laid with tiles on the following day, or within 3 days at the latest. For elastic and textile floor coatings, Okatmos® DSG requires two work steps: it must be primed and then used for filling within 3 days. If parquet floors are laid with SMP adhesives, the substrate must be primed with Okamul PU-V schnell (“rapid”) in two work steps within the previously mentioned period.

As substrate preparation for composite constructions:

Lay the Kiesel Ki 881 Eco Sound Mesh on an appropriately prepared substrate as described above, fix to the wood substrate. Then rework with stable, self-levelling Kiesel screed or Kiesel tile adhesives in accordance with manufacturer requirements.
