    Surface Preparation

    Ensure all surfaces are clean, dry and free from grease, oil and any other contaminants.

    Bare steel should be free from dust, rust and scale. Blast cleaning to SA 2½ is recommended. If blast cleaning is impractical, mechanical cleaning should be employed but hand cleaning does not clean the steel to the required degree. Any oil or grease should be removed with solvent before de-rusting. Where blast cleaning is carried out after assembly, special attention must be paid to edges, corners, nuts, bolts welds, etc. Welds should, if necessary be ground and all weld spatter, slag etc. must be removed.

    Existing painted surfaces - Surfaces should be cleaned, degreased and sanded to ensure an adequate "key" is produced. Remove all loose and flaking material and treat bare areas as new substrate and prepare accordingly. Apply to small test area first to ensure no reaction with conventional paints.

    Maintenance: Remove all marine growth, oil and grease. High pressure wash with fresh water. Remove all loose coating and power tool clean areas of breakdown. Bare areas should be spot primed to full film thickness prior to application of full coat.


    • Mix well before use.
    • In confined spaces, provide adequate ventilation during application and drying.
