DESCRIPTION : Bituprime SB is a quick drying solvent based low viscosity bitumen primer. It is used as a primer coat on masonry and concrete substrates to improve the adhesion of bitumen based membranes and coatings. Bituprime SB is low in viscosity, which allows it to penetrate into the concrete pores and improve the adhesion between the membrane and the concrete surface. In addition to that, the primer also acts as a binder for the dust particles which gets accumulated on the concrete surface even after cleaning.
Fields of application : Bituprime SB is used as a primer and sealer coat prior to the application of bitumen based waterproofing membranes and coatings.
Application Instructions : 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 primer 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, nail head protrusions, structurally unsound and friable concrete shall be removed and repaired with a suit-able Polycrete* concrete repair mortar. The surface must be dry before priming with Bituprime SB.
Application : Mix the contents of the pail or drum for a few minutes to remove any sediments. Apply the primer @4-6 m²/L to a clean smooth and dry surface by brush/roller. Allow the primer to dry prior to the application of the membrane. For highly porous surfaces application of a second coat is recommended.
Coverage : The coverage is 4-6 m²/L/coat. However, the coverage will depend on the porosity of the substrate. In order to ascertain the exact coverage, a trial application is carried out at site.
Storage & Shelf : life The pails and drums must be stored in a covered, dry and shaded area, away from direct sunlight, UV and other sources of heat and protected from extreme temperatures. The shelf life of the product is up to 12 months if stored as per the recommendations. Excessive exposure to sunlight TDS_Bituprime SB_RTL_1116 fast drying BITuprime sb Henkel Polybit Industries Ltd.

Health & Safety : Bituprime SB contains volatile solvent with a low flash point (38°C). It should be kept far away from naked flame. Avoid inhalation of vapors and ensure there is adequate ventilation in the work place. Gloves, protective masks and goggles should be worn during application. If swallowed seek medical attention immediately.
