SikaMembran® Universal
Vapor/waterproofing membrane for facades - low vapor permeability
SikaMembran® Universal is an EPDM sheet membrane with a high vapor diffusion resistance (sd value 62 m) and is thus applicable on both the warm (high vapor pressure) and the cold (low vapor pressure) side of the construction under most climatic conditions. The SikaMembran® system is a high-performance 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.
- Highly flexible waterproofing and vapor control system

- Provided with CE-mark according to EN 13984: 2011
- Meet fire retardant requirements of EN 13501-1 Class E under free suspension
- 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
- Ozone- and UV-resistant

Areas of Application
The flexible SikaMembran® Universal sheets, installed between structure and incorporated units (e.g. facade elements, windows, etc.) using a suitable adhesive, for example SikaBond® TF plus N, provide a secure and durable vapor barrier, as well as a waterproof seal at transitions between building elements, in curtain wall facades, ventilated facades and window installations.This product is suitable for experienced professional users only.
Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Application
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® Universal sheet tension-free and in a way 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 a period of 30 minutes after installation.
Application limits
SikaMembran® Universal is not resistant to mineral oils, petroleum, benzene, fuel and toluene etc.
The bond line of the membrane must not be in permanent contact with water.
