Application Information

Instructions for use

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.

Moss and lichen must be removed physically followed by treatment with fungicidal wash. After treatment, it must be washed down thoroughly with clean water and allow to dry.

Priming

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

Mixing

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

Application

For waterproofing underground structures, the bituminous emulsion shall be applied by brush or roller depending on the dry film thickness required. 300 micron dry film thickness (DFT) can be achieved when applied at 3m² /Lt/coat. The two coats must be applied at right angles to one another with a minimum of 6 hours intervals between each application at 35°C. Ensure that coat is completely dry before the next coat is applied.

Cleaning

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

Recommendation

Do not apply subsequent applications if the membrane is punctured or damaged.
