Step by step

The application temperature should be between 5°C to 55°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the self-adhesive waterproofing system is as follows:

SURFACE 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 with a suitable POLYCRETE* concrete repair mortar.

PRIMING

The adhesion can be improved by apply POLYPRIME SB* (Solvent based primer) @ 4- 6 m2/lt to a clean smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. In addition, the primer also acts as a binder for the dust which gets accumulated on the surface even after cleaning.

APPLICATION

Unroll only the required length and cut the pieces to the desired shapes and size. Place the pieces of membrane on the area to be covered and check whether they match with the profile of the marked substrate. Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen the membrane from the center to the edges with a wooden press in order to remove any entrapped air. Furthermore, an iron roller can be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with the base surface ensure a minimum of 50 mm overlap.
