Corroseal Rust Converter FAQs

Case Chemicals have Corroseal products and we are answering some of the most frequently asked questions of the rust converter.

Is there are a surface preparation needed to apply Corroseal?

There are no lubricants that will need to be added to the surface, however, you will need to remove any old, flaking paint, rust, and any other visible debris. Proceed to wash the surface thoroughly with an appropriate cleaner to remove any oils, or other contaminants. Ensure the surface is dry and clean prior to applying Corroseal.

Will I need to thin Corroseal?

Corroseal does not need to be thinned as the formula itself is quite sensitive.

Will I be able to apply a primer over Corroseal?

You will be able to apply a primer of the product, however this is not necessarily needed. If you do use one, it is recommended that you use an oil based primer.

Can Corroseal be used on galvanised steel?

As galvanised steel has a coating that includes zinc – this will prevent any corrosion on the material and Corroseal will not be effective over non-rusted galvanised steel.

If there is rust on the galvanised steel surface, test a small area to determine whether there is enough rust present for the Corroseal to be effective.

Can I apply Corroseal on non-rusted steel?

You can, but it will perform better when rust is present. Be sure to not apply Corroseal over any steel product that has been chemically treated.

Can Corroseal be applied over old paint?

Corroseal will etch prime tightly adhered primer or old paint that is on a steel surface.

How should I protect myself when applying the product?

Ensure that you use Corroseal in a well ventilated area – if you are spraying the product, wear gloves, a mask and goggles.
