how do you degrease metal before painting?

Answer 1

A water-based cleaner/degreaser like Aquaklean made by KBS Coatings is best. It's a heavy duty cleaner which will rinse clear without leaving any residues. Residues will interfere with paint adhesion on metal surfaces. I'd follow up with a treatment of RustBlast which will gently etch the surface for an anchor pattern and also leave a zinc phosphate coating for good paint adhesion. To guard against rust, use 2 thin coats of a nonporous paint like RustSeal. You can topcoat RustSeal with any paint system if you want or leave alone.

No. WD 40 is an oil based product and it will act as a bond breaker to any paint or primer. You need to use a degreaser of some sort to remove the oil. You can use something as simple as Dawn dishwashing liquid in warm water. Wash really well and reinse even better then let it dry. Once it is dry you can paint it with a spray paint such as Rustoleum, which has a additive to help protect against rust. If rust is present now you can and should use Jasco Prep and prime to treat the rust before painting. This is a liquid that goes directly on the rust and it forms a ferrous oxide when it chemically reacts with the rust. Once it turns blach and dries it can be painted directly. Good luck.

use a petroleum based product first. Grease disolves grease. Greased lightening is good. Then before painting you must clean all oils from it and an denatured alcohol is the best thing to use.

''accetone ''is the best cleaning fluid to use on metal to degrease it. Read directions on can before using it. Very dangerious around a flame , smoking, in a closed area.

if you can't run it through an industrial de-greaser you can use paint thinner or another solvent like Acetone to clean it, Acetone works very well, some home improvement stores carry it.

Answer 10

"Greased Lightning" or "Mean Green" sold in grocery stores, Walmart, are both very good at removing grease and oil from a variety of surfaces. You don't want to get either of them on your hands for extended amount of time.
