Preventing metal objects from developing rust is all about ensuring durability and a high-quality finish. Only professional spray painters who use a spray booth can offer this kind of commercial finish. Booth spray painting is undertaken in a fully pressurised and filtered spray booth, free from airborne particles, dust, dirt and other debris that could otherwise settle on the wet paint.
This method of spray painting ensures a flawless finish every time and allows technicians to concentrate on achieving the most precise chemical balance for your metal object to be completely rust-resistant. Painting in a spray booth also means that technicians can measure dew point, humidity and atmospheric temperatures to determine the ideal paint system for your product, according to the environment in which it will reside.
Do you have a metal object, product, piece of equipment or machinery that needs to be finished with a rust-resistant coating? Booth spray painting is the best way to protect your metal item from rust and corrosion!
Call us now on 07 How commercial spray painting stops rust. How does rust form? The spray painting process to prevent rust Spray painting is one of the most effective ways to prevent rust from occurring on your metal objects. Any metal made of iron or alloys containing iron, such as steel, will rust with enough exposure to oxygen and moisture. Paint offers one way to spare these rusted pieces from the junkyard and restore their looks while lending them a pop of color.
Read about them below before going to the rescue of your rusted possessions with paint. If rust has partially or fully eaten through the metal i. A primer can help paint adhere to a rusted metal piece, but you still must first remove as much loose rust as possible from the surface first.
Otherwise, the metal will continue to shed the loose rust, pushing the dried paint coat upward until it blisters or peels off. To avoid this, detach any hardware screws, nails, etc. Then, when no more rust flakes off, remove grit, grime, and grease. Let the metal air-dry completely before breaking out the primer. With the loose rust gone, your metal may either show extensive surface rust or little to no rust.
Good news: You can cover up either! Paints will also create a protective layer over metal objects and prevent moisture from reaching them. Of course, no barrier can completely stop moisture from getting through, but painting can be a simple and easy way to slow down rust. If you already want to paint the object a different color or get a different finish, this is an ideal solution. It is important to use the right paint to prevent rust.
Finally, be careful of welded joints or bolts. If there are any weak spots in the painted layer or any crevices not filled, these areas will start to rust. The best way to prevent rust may also be the most obvious—keep the object away from moisture. Water reacts with iron to form rust, so an environment with no moisture will not create rust. However, keep in mind that even regular air contains some moisture in the form of humidity.
This, of course, would make the object difficult to use, so it makes more sense to prevent rust during storage or shipping. Galvanizing applies a protective coating of zinc over iron or steel. Since zinc corrodes about 30 times slower than iron, galvanizing can be a cheap and effective way to prevent rust.
Like all of the ways to prevent rust, galvanizing has limitations. Galvanizing also changes the outward appearance of the metal, and the extra layer can cover up parts of the component, such as the threads on a screw. The process of blueing steel actually creates a new layer that is similar to rust, but much less damaging.
Blueing creates a layer of magnetite, also called black iron oxide, and gives metals a black or namesake blue appearance. Blueing is usually accomplished by applying high temperatures and a salt solution. This process is commonly used to economically protect firearms from rusting.
Blueing works best when the steel is also regularly oiled. First, static electricity binds a powdery substance made from acrylic, polyester, epoxy, polyurethane or something else to a metal object. Then, the powder melts in a furnace into a uniform, solid layer. Powder coating, like painting, covers a metal component in a protective layer. This layer will prevent moisture from reaching the metal and therefore prevent rust. For powder coating to effectively prevent rust, the coating must be intact.
Any weak areas will expose the metal and create an entry for rust.
