ADVANTAGES

• Simple brush application

• Rapid drying

• Can be used with potable water

APPLICATION:

Preparation

New surfaces must be cleaned to remove all traces of grease, oil and other foreign matter. All mill scale and any rust that has formed must be removed prior to painting. Where previous paint is firmly adhering and sound, it need not be removed. All loose flaking paint, scale, rust, dirt, grease etc., should be removed so that the surface is completely free from loose matter. On surfaces where all existing rust cannot be removed and where long term protection is required, use a fast drying red lead primer, zinc phosphate or other rust inhibitive primer in accordance with the manufacturer’s instructions, and ensure this is dry before proceeding with the treatment. On clean, rust free surfaces where priming is required, apply one coat of Bitumen Primer by brush and allow to dry, under normal ambient conditions, for 20 - 40 minutes. Black Bitumen Paint can also be sprayed or dipped; for dipping it can be thinned if necessary using white spirit.

Placement:      

A minimum of two coats is recommended to eliminate pin-holes and inadequate coverage of high spots. Apply second coat after the first has dried.

N.B. For best results on cold water storage tanks, three coats are recommended.

Black Bitumen Paint should be allowed to cure at ambient temperatures for a period of at least seven days prior to contact with potable water.

N.B. Black Bitumen Paint is NOT suitable for use in fish ponds.

Cleaning

Tools and spillage may be cleaned using white spirit or paraffin
