Rust Proofing for a Tin Roof

Q. I have a old house with a tin roof which is thoroughly rusted but not leaking and still structurely sound.what can I use to rust proof before painting?

First and foremost you must clean and prepare the surface of the metal by removing all loose paint, rust, dirt, oil, and grease. After cleaning the surface, Sand or abrade any remaining paint with sand paper or a wire brush. Wash the surface clean again, and remove all sanding dust.

Typically a corrosion resistant primer would be applied to the metal roof, followed by a compatible top coat. Consult with your local paint supplier, ask for specific recommendations for a compatible primer and top coat system to use for this application.

Please be aware that paints, coatings and solvents are chemicals and therefore you should always pay attention to proper handling procedures and be prepared to wear protective clothing, such as respirators, gloves, coveralls, etc. For further information on the health and safety requirements for the coatings and solvents you wish to use we strongly advised you to contact your local coating supplier. If possible, go the extra step and look for this information on the website of the product vendor.
