LAMA SELFSEAL
LAMASELFSEAL self-Adhering sheet is constructed of a glass mat carrier coated with our popular blend of SBS polymers, premium asphalt, and chemical additives that gives the membrane the perfect combination of durability and flexibility. LAMASELFSEAL top surface is a smooth HDPE layer, and the under surface is an easily detachable silicon-based release film covering a highly adhesive layer of asphalt.

Application Method.
- The surface shall be clean from all contaminants such as dust, oil, and grease, and free from loose materials.
- Prime the surface with LAMAPRIMER MR at a rate of 0.3-0.5 It/m2, depending on surface smoothness, allow it to fully dry.
- Place down the rolls starting from the lower edge, unroll, and align beside each other with 100mm side lapping and 150mm end lapping.
- Peel off the release film from the lower side, start unrolling the membrane and apply pressure from the center towards the edges making sure trapped air is driven out.
- Application temperature should be between -5 to 55 °C.
- The membrane must be protected from site activities, sun, and weathering conditions
