Vapourseal is a plasto-elastic, single-component sealing adhesive, based on innovative polyacrylates, for creating airtight and vapour-tight connections indoors with all types of vapour barrier films, including those made of PP and PE. Ideal for bonding vapour barriers to brick or other fast-construction materials. Vapourseal is also particularly suitable for airtight bonding of wood-based panels in timber frame construction.Special characteristicsAirtight and vapour-tightExcellent adhesion to all types of vapour barrier filmsGood adhesion to slightly damp surfacesPermanently flexibleGood slump resistanceSolvent and isocyanate-freeUV-resistantPlasticiser-freeApplicationFor airtight connections with all types of vapour barrier films on various building substrates. To create airtight connections between adjacent building components. When applied correctly, it ensures airtight and vapour-tight connections in accordance with the requirements of DIN4108-7 and NBN EN13829.Instructions for useApply a bead of adhesive of approximately 5 mm on one side of the edge of the vapour barrier film to be bonded, using a manual or pneumatic sealant gun. Apply the vapour barrier film against the substrate with sufficient room for movement so that expansion of the structure is accommodated. Do not flatten the adhesive bead completely so that an adhesive thickness of 1 to 2 mm is maintained. Provide a minimum adhesive width of 25 mm. Vapourseal can be removed immediately after use from materials and tools with Soudal Adhesive Cleaner 90A or Soudal Swipex.
