Description

YHBituprimer-4035 Water-based Bitumen Primer is a quick drying water 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. YHBituprimer-4035 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 and preventing moisture penetration.

Construction method

Spraying application is recommended

Construction process

Substrate treatment → Primer application → bitumen based membrane application → Protection lay.

Key construction processThe application temperature should be between 5°C to 45°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 YHBituprimer-4035;

·Application: Remove any sediments. apply the primer @0.3kg/m² to a clean smooth and dry surface by spraying application that is recommended. Brush/roller can also be used.Allow the primer to dry prior to
