The metal curves from the locksmith fit well with the house, but are they rusting away? Then it is time to remove rust from the garden gate or balcony railing and order a freshness cure.

It begins with rust at first sight and can expand to dangerous holes in garden furniture, pipes or railings. Rust eats into the metal and literally dissolves it. Rust occurs when iron, copper or aluminum come into contact with air, oxygen and moisture. However, if the railing is still stable, it is worth the tedious work of removing rust and refreshing it.

When restoring attacked surfaces, it is particularly important to ensure that the rust is removed thoroughly. Otherwise it will eat its way under the new paint. Read our step-by-step instructions here.

Step 1: remove rust

Remove the loose rust layer with coarse metal sandpaper (80 grit) and wire brush. A wire brush insert, which is in a drill, makes the job easier. Set the drill to a low speed, otherwise the wire brush will polish the metal instead of cleaning it. Electric grinders, such as angle grinders, are suitable for larger areas. Small hobby grinders that are held in your hand like a thick pencil are good for decorations.

When working with electrical appliances, rust particles are often thrown away: therefore wear safety glasses. A protective mask prevents you from inhaling fine dust. If you want a perfect paint surface, the railing must be bare and smooth. Continue in the second pass with 100 grit, finally smooth with 120 grit. Grease and oil make the primer and paint adhere poorly: therefore wipe off residues with lukewarm water plus a degreaser.

Step 2: treat rust

It is easier to only remove the loose rust and treat the stuck rest with a rust converter: this conjures up a protective layer from the rust that is suitable as a primer. However, a somewhat rough surface is created.

If the rust converter is dry, painting is already on. Resin varnish or epoxy resin material are suitable. The latter is more expensive, but mechanically more resilient. Tip: As a spill protection to strip off the brush, stretch a strip of masking tape across the paint can. Prime bare ground metal first, then finish coat.

This will prevent rust

Only sealing the surfaces protects the material. When choosing the right rust inhibitor, it is important to differentiate between ferrous and non-ferrous metals. There is a wide range of rust inhibitors for iron and steel. The experts at the international "Paint Quality Institute" recommend the use of acrylic-based paints because of their high durability and color stability. To avoid damage to the material, the sealer should be applied as early as possible. Metals such as brass, zinc, copper or aluminum have the disadvantage that paints adhere poorly to their surface. It is therefore advisable to clean the surfaces thoroughly with a metal cleaner before applying the rust protection agent and then to coat them with a special adhesive primer.
