How to paint aluminum window frames

Updated July 01, 2018

Aluminium windows frames form a tight seal and provide more soundproofing than vinyl windows. They're durable and strong and require little maintenance. They can be purchased pre-painted or you may choose to paint them to match your decor. Aluminium window frames can be quickly and easily spruced up with a little prep work and a couple of coats of paint. Whether you want to change the colour or cover up damage, here's how to paint aluminium window frames.

Clean the window frames with warm, soapy water and a soft cloth. Rinse well with hot water, and dry with a clean cloth.

Get rid of difficult stains and grease by spraying on a thin coat of WD 40. Use a toothbrush to scrub spots. Wipe with a clean, soft cloth. Be sure to remove all of the residue from the cleaning process.

Use painter's tape or masking tape to protect the glass or screens. If you're using spray paint, cover the glass or screen with newspapers and tape it securely.

Apply a metal primer or a self-etching primer according to the manufacturer's instructions. Let dry.

Paint the aluminium with either interior or exterior paint, depending on which side you're working on. Let dry and apply another coat.

Remove the tape by slowly pulling it away from the painted area at an angle. Use a razor knife to scrape up any paint that spilt or seeped onto the glass under the tape.

Tip

Grease left on the frames before painting can bleed through over time.
