Repaint the metal shed

Preparing to paint the shed

1. Thoroughly clean the tool shed from all adhering dirt with a high-pressure cleaner.
2. Wash it off with a degreasing agent. This works quite well with an addition to the garden hose, car washing or a pressure sprayer. Do not use moisturizing detergents, but a strong household cleaner such as soda cleaner.
3. Finally, the metal shed must be rinsed again thoroughly with clear water from the garden hose and dried well.
4. Now it's a matter of removing loose paint and rust. This works best with a wire brush. If you need to remove rust from larger areas, use a rotating steel brush (drill). Be sure to wear protective goggles when doing this work.

Important information about painting metal houses

Now it depends on which metal the shed is made of. If you don’t know when you bought it or the metal house was already on the property than you Having got this, you need to try to find out what material the house is made of has been.

• If the house has some red rust spots and does not show any silvery-gray surfaces under the paint - you can indicate that see the edges of the rust spots quite well - then it was probably made of sheet steel or iron. In that case, paint it with a conventional anti-rust paint and primer. Combination paints, rust protection, primer and topcoat are less suitable for this use.
• If the house is made of galvanized sheet steel, there should be almost no rust spots - but there is usually an accumulation of rust on the edges. Carefully scratch off the top coat at one point and see whether there is a light gray, silvery background. Should the shed be overall silvery-metallic and the layer is difficult to scratch off, whereby if metal shavings come loose, then the house is definitely made of galvanized sheet metal or aluminum. Use a magnet to test if it is magnetic. Magnetism speaks for galvanized sheet steel. In this case, you must ensure that the rust protection and primer are suitable for galvanized sheet metal.
• If the metal is not magnetic as described, then it would have to be made of a non-ferrous metal, i.e. non-ferrous metal such as aluminum. In that case, always use a bonding agent for aluminum. If the tool shed has not yet been painted, you have to sand the entire surface of the house with an abrasive fleece.

Notes on painting the metal shed

• Do not overdo the preparatory work. If the tool shed is hardly soiled, the use of a high-pressure cleaner is not necessary. Houses made of galvanized sheet metal or non-ferrous metal do not need to be treated with a steel brush. Do not be too brutal in the preparatory work with the necessary care.
• If you want to paint a new tool shed made of galvanized sheet metal, you must wash it off with ammonia before you paint the bonding agent. Be sure to wear gloves when doing this. A galvanized sheet metal shed does not need to be painted, but you can paint it.
• You can also paint houses made of iron with a special spray paint, in which you use a special device to electrically charge the house while spraying. This is how the metal attracts the color. This is distributed evenly into the cracks.
• Always use paints that flow well and also penetrate small cracks, because the paint should not only beautify the metal of the tool shed, but also protect it. To do this, it must be able to penetrate into all the cracks.
