Surface preparation

The surface of the concrete shall be sound, clean and uncontaminated. 

This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base.

Hot, very dry or porous surfaces should be primed before applying ASFABIT RBL+.


ASFABIT RB+ should be stirred before use until a uniform color and consistency is achieved. Product is ready for use.


For waterproofing underground structures, the bituminous emulsion shall be applied by brush or squeegee at a maximum rate of 200 microns per coat. 

The three coats must be applied at right angles to one another with a minimum of 6 hour intervals between each application at +25°C. Each coat must be completely dry before the next coat is applied.


ASFABIT RB+ products should be removed from tools, equipment and mixers with clean water prior to the initial set. Cured material can only be removed mechanically.
