Description
SikaMembran Eco Uni is an EPDM sheet membrane with a sd value of 40 m. The SikaMembran® Eco system is an economic vapor control system comprising of various EPDM sheet membranes providing vapor control layers and waterproof barriers for curtain walls. They are suitable for most climatic conditions in combination with the appropriate adhesive.
PRODUCT BENEFITS
- Highly flexible waterproofing and vapor control system
- Fast, easy and secure application even in corners
- Provided with CE-mark according to EN 13984: 2011
- Meet fire retardant requirements of EN 13501-1 Class E
- No additional mechanical fixing necessary
- Membrane pre-treatment free
- Suitable for uneven substrates (blowholes in concrete), leveling of substrate by adhesive
- Suited to site conditions
- Durable bond and barrier/seal
- Very good ozone and UV resistance
Areas of Application
The flexible SikaMembran® Eco sheets, installed between structure and incorporated units (e.g. facade elements, windows, etc.) using SikaBond® TF plus N adhesive, provide a secure and durable vapor barrier and waterproof seal at junctions between building elements mainly in curtain wall facades but also in ventilated facades and window installations. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Surface preparation
Prior the bonding process ensure that substrates are sound, clean, dry, free from dust, grease, oil and loose particles.
Application
Apply SikaBond® TF plus N adhesive to the corresponding structure or components (nozzle diameter approx. 8 mm).
By using a clean spatula, spread the adhesive bead to approx. 4 – 5 cm width and 1 mm thickness.
Install the SikaMembran® Eco Uni sheet tension-free so that movement of the connected building parts can be accommodated without damaging the membrane. Press the membrane sheet on the adhesive by a plastic roller. The membrane must be fully bonded over a width of 4 cm. Where overlaps are required ensure at least an overlap of 5 cm.
The membrane might be re-adjusted during 30 minutes after installation.
Application limits
SikaMembran Eco Uni is not resistant to mineral oils, petroleum, benzene, fuel, and toluene.
The membrane is not suitable for long term immersion or standing water.
