Painting a material that rusts, usually an iron rich material like steel, keeps the metal from exposure to the environment such as air and humidity. Rust is actually the oxidation of metal, and protecting metal with paint does not allow this to happen.
Rust needs water and oxygen to occur and paint keeps both of these from coming in contact with the metal.
it stops oxygen or water getting to it
Real texture physically exists on the art object- consider rust on a metal statue, or thickly-applied paint on an oil painting. Visual texture is the aesthetic representation of real texture- consider a photograph of rust. It shows the texture, but the photograph itself is smooth. Likewise, a smooth painting depicting rust.
Donald Rust was famous for painting and sculpting portraits of depressed clowns. In 1981, he painted "Emmett Kelly Jr.". The painting is being sold by collectors online for between 150 and 250 dollars, and is highly sought after.

You can prevent rust by following these simple steps:Ensure that your surface is clean, dry and rust free prior to paintingApply a complete coat of metal primer to all exposed surfaces at the proper thicknessClean and sand the primer prior to paintingApply two full coats of either an acrylic DTM or oil based metal paintIf the surface is damaged later, touch up the paint immediately.That along with keeping the surface clean of contaminants and applying a coat of wax should ensure that the surface remains rust free for quite awhile.
Kill rust, or direct-to-rust primer and paints, do not actually "kill" the rust, they encapsulate the rust, preventing oxygen and moisture from contacting and spreading the rust. Unlike other paints, they are impervious to moisture and that helps to considerably slow the growth of rust.
by painting them at regular intervals
Iron can be prevented from rust not only by painting but also by coating the iron byzinc . But when we paint iron ,the hydrated oxide presented in the rust iron(Fe2O3.2H2O)can be prevented . Reaction of the iron with air ,water Etc can be prevented.
zinc is used to prevent rust.
when a coating of paint is applied to steel, it seals the from the air. When raw metal is exposed to air (specifically oxygen), a process called oxidization gradually occurs which creates the rust. Good surface preparation, followed by a primer and a top coat will barrier the steel from the elements, therefore prevent oxidization and in turn prevent rust.
Rust is specifically oxidized iron and the most common way to prevent it is by painting it. Additionally a common pre-consumer method is to electrochemically add a layer of zinc on the iron which is commonly seen in galvanized nails. The zinc will only be oxidized for the first few nanometers of the layer and it will prevent oxygen from reaching the inner iron.

Galvanising or painting both prevent iron from rusting. Painting is less expensive but also less permanent and the treatment needs to be repeated as the paint flakes off.
well according to me it is supposed to be coated with paint, so that it doesn't rust but there can be other ways too. painting is the best.
Nothing spectacular happens-- this is a chemical change. The useful properties of iron are destroyed when it rusts, so much is usually done to prevent rusting -- i.e painting. other coatings that prevent rust. If you can keep the oxygen away from the iron, it will not rust.Isn't it that it makes iron oxide? or is rust really iron oxide?--different person
Zinc is commonly used to coat iron to prevent rust.
