Application procedures may vary slightly depending upon site conditions. The general recommended guideline for the application of the bitumen coating system is as follows.
The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil, grease.
Light mechanical grinding/grit blasting/high pressure water jet may be used to clean the surface of all the contaminants depending on the degree of contamination on the surface to be coated.
All surface imperfections and protrusions shall be removed and repaired.
Structurally unsound and friable concrete must be removed and repaired with a suitable concrete repair mortar.
Priming
SAB® Coat Rubberized 10 It is highly recommended to apply a priming coat prior to the application of the SAB Coat Rubberized 10 coating on the substrate.
The primer can be prepared in the site by diluting SAB Coat Rubberized 10 with 20% water and applying this diluted coat as the primer. For very dry and porous substrates apply two coats of this primer.
The primer can be applied to damp or freshly cast concrete surface also. However, it should not be applied on waterlogged or flowing water areas.
Further coats shall be applied only after the primer coat dries off completely.
In case of delay in application of the topcoat for more than 24 hours, a fresh coat of primer shall be re applied.
