Step by Step

Surface preparation 

A smooth, regular and dry surface is always a must for good application. The substrate should be completely free of any protrusions or cavities. The presence of oily substances, frost or other moisture should be completely avoided.


The installation procedures are to be as follows:

  1. Unroll only the required length, and cut the piece to the desired shape and size.
  2. Place the pieces of membrane on the area to be covered, and check whether they match with the profile of the marked substrate.
  3. Al Hosan can be placed either by pour and roll method or by the use of a contact adhesive for vertical areas.
  4. Place a Bituboard on top of the membrane soon after the application in order to prevent any damage from exposure to sunlight, backfilling.
