Multipurpose adhesive
MULTI
Eurovent® MULTI is a solvent-free multipurpose adhesive and sealing compound based on acrylic emulsion, designed for bonding and sealing vapour control membranes and foils inside buildings, as well as for creating airtight expansion joints. It offers very high resistance to ageing together with excellent flexibility and extensibility, allowing it to effectively accommodate structural movement. It can be plastered and painted over. Eurovent® MULTI has been certified by the Passive House Institute in airtightness class phA. The product also provides verified airtightness in accordance with DIN 4108-11.
Advantages:
- Certified Passive House component
- Flexible and extensible
- Highly resistant to ageing
- Accommodates structural movement
- Solvent-free
- Airtight according to DIN 4108-11
Application and Technical Data
Eurovent® MULTI solvent-free multipurpose adhesive and sealing compound is designed for bonding and sealing vapour control membranes and foils, highly vapour-permeable roof membranes and low vapour-permeable roofing foils inside buildings. It is also suitable for creating and sealing expansion joints. The compound can be plastered and painted over.
The application temperature ranges from +5°C to +30°C. Surfaces to be bonded should be clean, degreased and absorbent. A suitable primer should be applied beforehand to weak, dusty or fibrous substrates.
The recommended thickness of the applied compound is approximately 6–8 mm. Before curing, product residues can be easily removed with water. Once cured, dried residues can be removed with a suitable cleaning agent applied locally to the remaining compound. If necessary, repeat the procedure until the desired result is achieved. Before using a cleaning agent, make sure that the substrate is resistant to its action.
Application should be carried out in a well-ventilated area. Once the sealant has fully cured, which takes approximately 12–24 hours, any characteristic odour should disappear completely.

System products
To ensure maximum performance of MULTI, it is recommended to use it as part of a complete roofing system together with:
- Eurovent® roof membranes (roof underlays / underdeck membranes), which provide a stable and airtight substrate for durable bonding and sealing of overlaps using MULTI,
- Eurovent® vapour control membranes (vapour barriers), where MULTI enables secure and airtight bonding of vapour control layers and their precise connection to the roof structure,
- Eurovent® sealing and adhesive tapes, reinforcing and complementing the performance of MULTI in areas requiring enhanced airtightness,
- Eurovent® installation accessories, improving the stability of the layered system and ensuring long-term durability of joints in detailing and flashing zones.
The use of complete Eurovent® system solutions guarantees high joint tightness, effective protection against moisture ingress and long-term reliability of the entire roof structure.
