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

Application Information 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. |
