Neutrarust 661® FAQs

Neutrarust 661®dries on the rusted surface and chemically converts to a black non-tacky hard layer forming an impermeable barrier to oxygen and moisture. The continuous chemical curing of Neutrarust 661® forms a chemical bond with the metal interface, pacifying, neutralising and chemically converting rust and therefore preventing new corrosion.

It is classified as non hazardous. Safe for international transportation by air, sea and road. MSDS available upon request.

It is used around the world by many different customers and suitable for use on any rusted ferrous metals, iron or steel object such as ships. drilling rigs, refineries, pipes, car or other vehicles, trailers, fences & gates, iron railings and staircases, sheet metal, cast iron, tanks, lawn mowers, boat, farm equipment, tractors etc.

Remove loose scale, flaky rust, all paint and dirt with thorough wire brushing etc. Reduce any high peaks of rust. Remove Acid, Alkali, grease oil and chemicals with detergent water wash then rinse surface with cold water. Paintwork  blistered by rust should be scraped down to hard surface. DO NOT REMOVE ALL TRACES OF HARD RUST. The area must then be adequately covered with Neutrarust 661®.   

Stir well before use and transfer a quantity of rust remover into a non metallic container for application. Apply the using a brush, roller or airless spray equipment. Work well into deeply pitted areas using a brush. Ensure all areas of corrosion are covered. Do not pour the unused rust remover back into the original container, as any contamination could degrade the fresh product. Depending on the condition of the surface, up to three coats may be required to ensure complete coverage and conversion of all corrosion present.

It will adhere to non-rusted or painted surfaces, but it does not provide any additional rust prevention when used on these surfaces. 

We do not recommend using inside a tank, but it is commonly used on the outside of large tanks.

It should always be applied neat from the container and not thinned with any products such as white spirit, water or methylated spirits. It is recommended that the container is either gently shaken or for larger containers stirred with a paddle mixer before being applied to any rusted surfaces.

This is dependent upon the application method and the condition of the surface. Coverage will be reduced on very rough or pitted surfaces. An application of a wet film thickness of 50-100 micron should cover up to 12 square metres per litre.

The black chemical compound layer is completely neutral and can be used as a primer without further treatment or if preferred apply a coat of primer. 

Although it’s not always required, it will accept most paints and if your surface is exposed to the elements, we recommend applying a quality paint. It will extend the life expectancy of the substrate from adverse weather including rain, salt mist and direct sunlight.

There are many good quality paints on the market and we recommend getting a good quality one that is specifically designed for your particular application. 

To achieve complete coverage we recommend applying 2 or 3 coats of Neutrarust 661® by brush, spray or roller. Cross brush for best results.
