Maximum safety with blower door tests

NoticeWÜTOP flat roof seal is ideal for bonding on WÜTOP vapour barriers and WÜTOP vapour retarders and has been tested on these films. For this reason, we recommend using WÜTOP films to achieve optimum results. The application surface must be dry and free from grease, chips and dust. Porous and absorbent surfaces, such as concrete, plaster, soft particle boards etc. must be pretreated with EURASOL AdhesionPlus or primer spray. The sleeve must be selected according to the duct dimensions to ensure permanent airtightness and strain relief. Sleeves are talc-powdered ex works. In the case of deficient sliding properties, please use the talcum powder sachet included and apply to the inner grommet or pipe.

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. If our free customer service provides technical information or acts as an advisory service, no liability is assumed in relation to the provision of this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee the consistent quality of our products. We reserve the right to make technical changes and further develop products.
