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.


The adhesion can be improved by apply
POLYPRIME SB* @ 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. 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
