  • Removing the backing membrane as you proceed.
  • Press firmly onto the surface. The membrane must be overlapped at the edge by at least 5-8cm and on the top by at least 15cm.
  • For a smooth finish, press membrane with a rubber hand roller, working from the center outwards, remove any air bubbles and creases ensuring firm contact is made with the surface.
  • The aluminium foil backing must not be removed.
  • Note:The product belongs to the self-adhesive material, one time paste can achieve the best waterproof effect. If the surface is porous, apply a coat of primer in a quantity of 70-150g/sqm. The use of primer is in any case advisable, and the manufacturers instructions must be followed. A wrong use of primer can be influence the membrane efficiency.
