Rust has a way of working its way into all our vehicles and all types of steel in our buildings. It is amazing how many new buildings even today show signs of rust on the uprights and balustrades within a year of completion. It does not say much for the way that the metal is prepared before use.

Rust removal, treatment and prevention is an important part of any metal preparation. It is much simpler to prevent the rust from starting rather than treat it after it has rusted.

What causes Rust?

Different kinds of materials will react with oxygen which forms a chemical compound. If iron combines with oxygen it forms an iron oxide or rust. If the iron oxidizes it can puff up or flake.

Water and salt will cause iron and steel to rust. Salt water will rust steel quicker than water as salt water is a better electrical conductor.

Vehicles and buildings near the ocean are more susceptible to rust from the salt in the sea air. This is one of the disadvantages of living next to the coastline.

Preventing Rust

To prevent rust we have to stop the air and water from coming into contact with the steel. The best way to do this is to apply a coat of grease or oil to the bare metal. The water repellent spray pack containers tend to evaporate before long and need continual repeat application.

When you apply a coat of rust proof paint, this works as long as it is not scratched or the rust will reappear. Then you will need to apply again.

Treating minimal rust marks

You will need:

· Emery Paper

· Paintbrush

· Rust proof paint or cold galvanizing paint

Method

Remove all old paint from window or door frames. Sand or scrape back to bare metal. When clean and free of dust repaint with rust converter, or anti rust. Paint with primer and topcoat or you could use a rust inhibiting epoxy, this eliminates the use of a primer.

Treating heavier rust

You will need:

· Wire brush

· Gloves

· Mineral turps

· Paintbrush

· Two part epoxy repair filler

· Rust converter

· Drill

· Safety goggles

Outside metal is often worst affected by rust. Wear gloves and safety goggles and brush affected area with wire brush. (Can use drill for bad areas) When done wash with mineral turps. Once dry treat with the rust converter. Fill affected area with the epoxy and sand smooth when hardened. Then paint.

Treating Rusted bolts

If your bolts and nuts are rusted in place, pour fizzy Coca Cola onto them, leave to dry now try undoing them.

That should help rid you of all those rusting problems, and have everything looking spic and span again.
