Blackguard is a liquid rust converter and primer which chemically converts and passivates rust present on the surface to a black film which resists further corrosion. The vinyl acrylic copolymer employed exhibits very low permeability to water vapour and oxygen.
NZFSA Approved C23 (all animal products except dairy).

Chemical & Physical Properties:
Appearance: White Emulsion.
Specific Gravity: 1.24.
Flammability: Non Flammable.
Solubility in Water: Emulsifiable.

Applications:
For use on rusted ferrous metals encountered in:-
All types of road vehicles.
Building steelwork.
Bridge pylons.
Cranes.
Pipe work.
Shipping, etc.

Instructions For Use:

1. Always decant sufficient Blackguard into a separate plastic container for use.

2. Never pour unused material back into the original container as any rust present will continue to react with the chemical.

3. Ensure that the surface to be treated is free from soil and grease.
4. Remove all heavy scale and loose rust, paint, dirt, etc. by wire brushing, chipping or either sand or water blasting.
5. It is important to ensure that rust remains on the surface as it is necessary for the chemical action to proceed.
6. Blackguard may be applied by spray, brush or roller. Two coats are recommended for maximum conversion and protection.
7. Blackguard may be applied to damp surfaces although protection from rain is necessary when the film is drying.
Blackguard is touch dry in twenty to thirty minutes.
8. Allow twelve hours drying time between coats and twenty four to forty eight hours before applying top coats.
9. Do not apply to surfaces where the temperatures are below 5C or above 40C.
10. Water based paints may stain if used over Blackguard. Try a small area first and if staining occurs, allow to age and retest.
11. Do not use primer over Blackguard coating.

Cleaning:
Rinse equipment with water immediately after use.

DO NOT use thinners.

Coverage:
Due to the variation of rust porosity an application of 10-12m2 per litre at an average film thickness of 75-100 micron per coat is envisaged.

Caution:
*Do not weld over or apply heat in excess of 100ÂșC to surfaces that have been treated with Blackguard as gases may be given off and re-rusting may occur.

*When applying by brush or roller pour small quantities into a separate container or tray as traces of rust picked up by the brush or roller will cause premature reaction. On completion do not pour any left over compound back into the original container.

*Do not apply to clean bare steel.
