features and benefits
fields of application
  • Water impermeable, protects moisture sensitive substrates.
  • Flexible, takes expansions, compensates irregularities in the substrate and variations in temperature.
  • Crack bridging, high reliability even when cracks in the substrates form at a later stage.
  • Ready to use, the waterproof membrane is only glued to the substrate.
  • Rapid application sequence, ceramic or natural stones can be immediately laid when the waterproofing membrane is fixed.
  • Reduces the ambient sound and impact sound of the installed ceramic or natural stones considerably.
  • Very low emissions, GEV-EMICODE EC 1.

  • For all sizes of ceramic and natural stones.
  • On moisture sensitive, absorbent substrates, e.g. particle boards, OSB boards, magnesite screeds, gypsum fibreboards, anhydrite flowable screeds or gypsum-based screeds.
  • On mineral, absorbent substrates, e.g. concrete, screed, and self-levelling compounds, e.g. PCI Periplan.
  • On mineral, non-absorbent substrates, e.g. old ceramic tiles, mastic asphalt screeds (only indoors).
  • On underfloor heatings.

  • On anhydrite screeds with a residual moisture level < 2% (measured with a CM meter) when laying ceramic and natural stones.
  • Also suitable in the dry interior under parquet elements (2 layers and 3 layers) with tongue and groove approved by the parquet manufacturer for full-surface gluing; on calcium sulphate screeds/anhydrite screeds at a residual moisture level smaller 1.5% (measured with a CM meter) when laying parquet flooring with PCI PAR 365 SMP parquet adhesive within the system with calcium sulphate screeds from CASEA GmbH and Knauf Gips KG.
