Prime the Surface if NecessarryĪpplying a primer is not really necessary anymore nowadays. Usually a thin coat of rust reformer will be enough in most cases. You can buy Rust-Oleum rust reformer at your local hardware store or right here on Amazon. It is easy to apply and it never failed me. I personally recommend using the rust reformer from Rust-Oleum. Some primers nowadays already stop rust from building anyways but I generally recommend applying a rust reformer anyway just to be sure. You might need to change the towel after a while if the surface was very greasy.įinally, after you cleaned the surface properly, use a rust reformer before painting the surface to ensure that no rust can build underneath the paint coat. This will clean the surface from any oil or grease that might be left on the surface. ![]() Use a piece of cloth or a towel to wipe the surface with some mineral spirits. If you don´t clean your surface properly then you might have a problem with peeling paint later on! Even if your metal is clean and no rust is present before you apply any paint or primer you should clean the surface from grease and dust. Clean the Surface With Mineral SpiritsĪs I said above, this step should not be skipped no matter what. This is by far the step that will require the most work but it will be worth it because by doing this you will ensure the longevity of the new paint job. You should remove all of the rust and paint before going to the next step. Then, when most of the paint and the rust are removed, I will go over the entire piece with a fine-grit sandpaper. You don´t want to damage the metal underneath. Try to be careful when using a wire brush. And then I will go over the whole piece with fine-grit sandpaper. I usually start by using a wire brush to remove any paint that is easily peeling of and to remove some of the rust, if present. You can buy a wire brush in your local hardware store or right here on Amazon. I recommend doing that either by using a wire brush to scrape the paint off or by sanding the surface. You have to remove any peeling paint before you can repaint the surface. If the metal was painted previously but the paint is not peeling then you can leave the paint where it is and simply continue with the next step. If the metal was already painted before and the paint is peeling or bubbling then you should remove the paint. The metal surface does not need to be sanded if it has oil, grease, or dust on it as this can easily be removed by using mineral spirits. Remove Peeling Paint and Sand if NecessaryĪs a general rule, it is only necessary to sand metal before painting if the metal surface has rust, paint, or something similar on it that needs to be removed. The surface doesn´t have to be perfectly clean yet. Then use the towel or a piece of cloth with some water to get rid of any dirt and dust that´s leftover. Use the brush to clean the surface of the metal from dirt, spider webs, and dust. In this step, we only want to get rid of dirt and dust. ![]() We will clean the surface again before applying the primer. You don´t need to clean the surface perfectly yet and you won´t need mineral spirits yet. I usually use a simple sturdy brush and a piece of cloth or a towel for cleaning. Before doing anything you should always clean the surface roughly. You should never skip this step no matter if the surface of the metal is clean or rusty. Clean the Surface Roughly From Dirt and Dust Some paints don’t require you to prime the surface in which case you could skip that step but I generally recommend always priming your metal surface before you paint it even if the paint doesn´t necessarily need a primer. The only two steps that you should never skip no matter what, are cleaning your surface and priming the surface. If you determine that one step is not necessary then simply skip it and look at the next one.
