Painting Rusted Metal: Everything You Need to Know
Seeing rusty furniture and metal can be an eyesore. It seems impossible to restore rusty objects that are already flaky, bumpy, and brittle. But just when you think you cannot save a rusted metal anymore, you can still actually do something about it. How? By repainting it.
Before you do that though, you need to do some proper priming and cleaning first. You can do the painting task by yourself or hire a professional painter in your area. By applying the right painting techniques, you can still save your rusted furniture and other items and give them another chance.
Can rusty items still be painted?
The short answer is yes, it is still possible to paint on rusted surfaces. Make sure to sand off the rusted area first before painting it the bare and cleaner surface underneath. However, you can still paint on the rusted surface, provided that the surface itself is still stable. Also, you will need to apply primer suited for metal before applying paint.
If you are concerned about whether the rust will show through the paint job, you don’t have to worry about it as long as the surface is primed properly. On the other hand, rust can still seep through paint especially if you use lighter paint shades. Rust conversion primer is a must to prevent rust from bleeding through the paint.
However, there are some objects that could be too rusted to paint. If the surface already has holes or is pitted and too brittle due to rust, or if there is no cleaner surface underneath after scraping. It would be a better idea not to paint the item and opt to replace the item instead.
Meanwhile, you should also consider safety before painting rusted items. For one, houses built prior to 1978 may still contain traces of lead-based paint. In this case, you should do all necessary procedures when working on items with traces of lead-based paint.
Tips on painting on rusted surfaces
Here are the necessary steps to take when painting rusted items such as metal fences and furniture.
Get rid of rust first.
Using a wire brush, scrub loose the rust first and remaining paint. Make sure not to overdo it, and work only on the loose rust. For larger loose rust, use a five-in-one tool or a putty knife to scrape the rust. After scraping the loose rust, lightly tap the metal using a hammer to determine whether the material is still durable enough to paint.
Sand and clean the surface.
After removing the loose rust, sand and clean the surface before painting. This is to smoothen the surface and make sure it is clean so that the paint will stick better. It may not be perfectly clean, but at least the majority of the debris is already removed. You may also use mineral spirits to remove the old paint. However, it can cause a rippled texture when you apply the new paint.
Use rust converter and paint away!
Apply rust converter on the affected area, making sure you only apply thinly. Let it dry for at least 24 hours before applying paint. For a hassle-free paint job, better hire a professional residential painter in Franklin TN.
