Painting Galvanized Steel – about how to prepare various examples of the right metal surface for painting. First, let’s discuss Galvanized metal. Galvanization protects steel very effectively against rust. But it doesn’t make a good key for paint, and many primers don’t grip the surface like this very well. To prepare this type of surface for painting, you must first remove all dirt and oil with white spirits on a cloth that is not hairy. Furthermore, if you work on a weathered surface; use zinc chromate primer. If you are busy preparing new galvanized steel for paint, use an etching solution followed by a calcium plumbate primer.
You need to clean the damaged area painting galvanized steel with turps and then apply some cold galvanized paint to the damaged part. Next, let’s look at iron and steel. You will need to prepare a new iron or steel surface or you will see preparing some old rusty metal to paint. If it is a new surface; wipe the protective oil with a hairless cloth dipped in turps. An old piece of sheet or similar material works well for this. Use sandpaper to remove visible rust and clean the entire surface. Apply good metal base paint as thin as possible. Another option is to use cold galvanized paint which will act as a rust and primary inhibitor.
If you need to prepare iron or rusty steel for a new coat of paint, you must first remove all rust using a wire brush and some sandpaper. You should always wear safety goggles and leather gloves to protect yourself when preparing any metal this way. Now you obviously need to empty the filler. After sanding, there will be blank steel edges which once again need to be broken. What about the painted metal surface but now there is rust that lifts the paint in the areas? Again, please remember to wear protective goggles and gloves when preparing metal this way.
Brush the paint with a wire brush and then scrape the remaining paint back to reveal the metal surface. You can use old knives, paint scrapers or rough files to achieve this. Be careful not to miss the hidden crust, if painted; it can easily lead to new attacks. After all the rust has been removed, you must treat the surface with rust, primer and sealer. Next, apply good metal base paint and then develop gloss paint in a thin layer until it is parallel to the existing paint. That’s the article about painting galvanized steel.
