Aluminum surfaced solar reflective self adhesive waterproofing membrane


Bitustick AL is a tropical grade polymer modified bituminous self adhesive waterproofing membrane. The bitumen compound is laminated onto an impervious, non-perforated, cross laminated solar reflective aluminum surfaced HDPE film.


  • Good resistance to water & vapor
  • Aluminum surfacing, Excellent solar reflectance
  • Specially formulated for tropical climates
  • Self adhesive. Requires peeling off of the silicone film and sticking to the surface
  • Excellent adhesion to vertical and horizontal surfaces
  • Good tear and puncture resistance
  • Excellent tensile strength in both longitudinal and transverse direction

Step by Step

Substrate preparation

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired.


Apply Polyprime SB* (Solvent based primer) @4-6 m²/L to a clean, smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. The primer promotes the adhesion between the membrane and the concrete surface.


Start the installation of all membrane plies from the low point or drains, so that the flow of water is over or parallel to the plies, but never against the laps. All overlaps at the membrane seams shall be installed so as to have "up" slope laps over "down" slope laps. Begin membrane application by unrolling the roll of Bitustick AL  membrane and aligning the side laps. Re-roll the roll halfway and stand on the unrolled portion to prevent shifting. 


Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen out the membrane from the center to the edges in order to drive out entrapped air with a wooden press. Furthermore, an iron roller shall be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with base surface. Side overlaps shall be a minimum of 50mm on the selvedge and end overlaps 100mm.
