Frequently Asked Questions About Restoring Metal Cabinets

Restoring old metal cabinets can seem daunting to DIYers. Here are answers to some of the most common questions about the process.

What type of paint should I use?

Exterior enamels or oil-based paints are best for painting metal as they adhere well and provide a durable finish. Latex can also work if properly primed first. Avoid chalk and milk paints.

Do I need to use primer?

Primer provides an essential undercoat that helps paint adhere to slick metal surfaces. It also prevents future rust and corrosion. Always prime metal before painting.

How do I get rid of rust?

Light rust can be sanded away, but heavier rust may need a rust converter product applied before priming and painting. For heavy rust, replacement of damaged sections may be needed.

What about lead paint concerns?

Take proper safety precautions by wearing PPE when stripping or sanding paint on vintage cabinets. Test for lead if you have concerns about existing paint being lead-based.

How do I get a smooth finish?

Proper prep work and applying thin coats of primer and paint will prevent brush marks and create a smooth surface. Sand lightly between each coat too.

What sheen should I use?

Satins and semi-glosses are good all-purpose sheens for cabinets. High-gloss can show imperfections easily. Use flat for a vintage look.

How do I repair damaged areas?

Fill dents, gouges and holes with metal/wood fillers designed for your specific cabinet material before priming and painting.
