Promac Galvprep is a multi purpose etch & rust cleaner is a ready to use cleaner and etching compound for the preparation of new, weathered or rusted galvanized iron, new or rusted steel, fibre cement, concrete roof tiles and smooth concrete paving prior to painting. It may also be used for pre-cleaning surfaces, where additional mechanical cleaning may be required on stubborn dirt or rust.

• Ready for use and easy to apply

• Contains special degreasing and etching compounds

• Cleaning compound for multiple surfaces

• Removes the temporary protective coating from new galvanised iron

• Removes surface oxidation from old weathered galvanised iron and steel

• Removes dirt, impurities, grease, and loose particles that compromise the paint system

• Kills algae, fungus and bacteria

• Improves adhesion of the primer and coating

New and weathered galvanised Iron or new (non-rusted steel): Apply Promac Galvprep liberally to the surface by using a non-metallic firm brush, broom, or scouring pad or spray to manageable areas at a time. Scrub the surface and leave Promac Galvprep in contact with the surface for 15-20 minutes. The surface will turn to a dark blackish colour. Do not allow Promac Galvprep to dry on the surface. If the surface is very hot, this will reduce the dwell time required to actively clean the surface. If this is the case, rinse the manageable area with cold water and then apply the cleaning process. Rinse thoroughly and allow to dry. High-pressure cleaning is recommended. Check that the surface is water break free. If not, or if the surface is still dirty repeat the above procedure. Coating time: In coastal areas prime the cleaned surface preferably within 2 hours but not more than four hours and in other areas the same day to prevent re-contamination of the surface.

Rusted galvanised iron or steel: Light or mildly rusted surfaces, apply Promac Galvprep liberally to surface by using a non-metallic brush, broom, or scouring pad or spray to manageable areas at a time. Scrub the surface and leave Promac Galvprep in contact with the surface for 15-20 minutes. The exposed cleaned steel surface will then turn to a copper colour, and if galvanised, this will turn to a dark blackish colour. Do not allow Promac GALVPREP to dry on the surface. If the surface is very hot, this will reduce the dwell time required to actively clean the surface. If this is the case, rinse the manageable area with cold water and then apply the cleaning process. Rinse thoroughly and allow to dry. High pressure cleaning is recommended. If the rust is still evident or there is severe rust, mechanically abrade or sand blast the surface to remove all traces of rust. Then apply the cleaning process as above. Check that the surface is water break free. If not, or if the surface is still dirty repeat the above procedure. Coating time: In coastal areas prime the cleaned surface preferably within 2 hours but not more than four hours and in other areas the same day to prevent re-contamination of the surface.

Fibre cement, concrete roof tiles and smooth concrete paving:

Apply Promac Galvprep liberally to surface by using a non-metallic brush, broom, or scouring pad (that will not damage the surface) or spray to manageable areas at a time. Scrub the surface and leave Promac Galvprep in contact with the surface for 15-20 minutes. Do not allow Promac Galvprep to dry on the surface. If the surface is very hot, this will reduce the dwell time required to actively clean the surface. If this is the case, rinse the manageable area with cold water and then apply the cleaning process. Rinse thoroughly and allow to dry.

Approximately 10-15 m² / litre per application depending on the type of substrate, condition and surface porosity. Spread rates are based on the product being applied to galvanised iron sheeting.

Clean all tools, brushes, rollers and spray equipment, while wet with water after use.
