As with any waterproofing membranes, proper application
is of paramount importance to obtain optimum product
performance. A smooth regular and dry surface is always
a must for good application. The substrate should be
completely free of any protrusions or cavities. The presence of oily materials, frost, dampness, moisture and any other
contaminants should be completely removed.

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. As the viscosity of the primer is low, it easily
penetrates into the concrete pores which promotes the
adhesion between the membrane and the concrete surface.
In addition to that the primer also acts as a binder for the
dust which gets accumulated on the concrete surface even 

1. Unroll only the required length, and cut the piece to the
desired shape and size.
2. Place the pieces of membrane on the area to be
covered, and check whether they match with the profile
of the marked substrate.
3. Peel off release film and carefully place the membrane
so as to ensure a minimum of 75mm overlap and then
smoothen the membrane from the centre to the edges in
order to drive out entrapped air.
4. In case the concrete structure is at a greater depth or is
going to be exposed to site conditions / weather for a
long period, place Bituboard asphaltic protection board
on top of the membrane soon after the application in
order to prevent any damage to the membrane.
