Areas of application

For indoor and outdoor use.
For floors.
For wet locations subject to non-pressing water such as bathrooms, showers in residential buildings, hotels, old people's homes and hospitals.
For balconies and terraces.
For all sizes of ceramic and natural stones.
On moisture sensitive, absorbent substrates, e.g. particle boards, OSB boards, magnesite screeds, gypsum fiberboards, anhydrite flowable screeds or gypsum-based screeds.
On mineral, absorbent substrates, e.g. concrete, screed, and self-leveling compounds, e.g. PCI Periplan.
On mineral, non-absorbent substrates, e.g. old ceramic tiles, mastic asphalt screeds (only indoors).
On underfloor heatings.
On green cement screeds (minimum quality CT F4) as soon as walkable and able to bear weight.
On anhydrite screeds with a residual moisture level < 2% (measured with a CM meter) when laying ceramic and natural stones.
Can be applied in the categories: EK-W-AIV-S, EK-H_(AIV)-S, EK-G-AIV-S, EK-H-(AIV)-S in accordance with the ZDB Merkblatt "Entkoppelungssysteme" (ZDB leaflet "isolating systems").

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 bonded 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.
