Rough concrete to be “faired up” before commencing application. Contact your local Parchem branch for suitable fairing products from our extensive range. Priming Index Bitumen Primer should be applied to all prepared surfaces prior to application of membrane and allowed to dry. Primer will take at least one hour to dry at temperatures 25°C and above. At lower temperatures allow additional drying time. Index Bitumen Primer should be applied at rate of approx. 0.13 litres /m² to the surface to which Vapordiffuser will be applied. The coverage rate for the primer will vary depending on the porosity of the surface being treated. Primer may be applied by brush, roller or spray equipment, coverage must be uniform. Primed areas must be covered with the membrane on the same day. Application Vapordiffusor to be torch bonded to substrate along with the overlaps which are ready for bonding in the longitudinal direction of roll. Crosswise the membranes are abutted and not overlapped. When the membrane has been installed, a strip of smooth / plain membrane (Fidia or Argo P), at least 15 cm wide, should be bonded over traversal joints. Protection Vapordiffuser is not designed as a stand alone product, it must have an additional layer of membrane applied. If final membrane is exposed to UV, a mineral finish is required (such as Testudo Mineral or Fidia Mineral). Supply Vapordiffuser: Roll width 1 m, length 7.5 m Coverage Vapordiffuser: Approx 7m² per 7.5 m roll Product Code: 742030 Index Bitumen Primer: Product Code: 742105 8m²/litre Note: No allowance has been made for wastage. Storage Store in cool, dry conditions ie. not exceeding 25°C. Rolls must be stored on end and must not be stored lying down. Index® Vapordiffuser
