Materials Needed to Paint Windows

Painting aluminum window frames has always been a quick and inexpensive project to complete to give your home a more appealing appearance. You'll need some common supplies and tools, as well as aluminum paint. You start with a good primer, which helps the paint adhere effectively, and then choose a paint in the finish that you desire, whether glossy, matte, or satin. 

When choosing gloss paint, keep in mind that a gloss aluminum coating is required to avoid wear and scratches. A few masking tapes, disposable rollers or brushes, drop cloths to cover the flooring, diluted detergent to clean the windows prior to priming and painting them, and a few masking tapes are needed. 

Any metal surfaces must be thoroughly sanded prior to priming and painting in order to achieve the coatings' best potential adherence. Update your windows before the days get shorter and the temps dip.  Here are some painting-related tips from experts for metal window frames.

You'll need the following tools for the job:

  • Masking Tape

  • Aluminum primer

  • Your favorite paint

  • Brushes/Rollers

  • Diluted Dish Detergent

  • Drop Cloths

How to Prepare for Painting Aluminum Windows

Proper preparation is critical for pulling off a successful paint job is preparation, no matter the surface you want to paint. The first step in preparing your aluminum windows for painting is cleaning them. Use warm water, soap or liquid detergents and a kitchen sponge to clean your window frames thoroughly. If you encounter any tough spots, you can use the abrasive side of the sponge to clear them. 

During the cleaning, it's also handy to have some wool wire or sandpaper with fine grain for scouring the surface of the aluminum frame. Scouring the frame will create micro-ridges on the surface, which will help the paint adhere better. The improved adhesion will enable the paint to last longer, especially if the frames aren’t powder-coated. Once done, use a clean cloth to dry the window frames. Set the frames in a well-ventilated space ready for painting.

Add primer

Starting your aluminum window paintwork with a base coat before adding a top coat will give you the greatest possible finish. Primer paints are specially designed to be used as base coats. Use a high-quality sprayer to apply the primer to the aluminum frames. You can prevent the primer from spraying onto the glass using painters or masking tape and a paper cover. The tape will also enable you to achieve a clean edge on the glass. Use the up and down strokes (for spray and brush) to uniformly cover the area as you start in one corner at the top, work across it, and then down to finish.

Apply the top coats

Once the primer has dried, use fine-grit sandpaper to get rid of any bumps on the base coat to create a perfect surface to apply the top coat, sand any minor bumps using fine-grit paper after the primer has had time to dry. Don't forget to vacuum or wipe the surface clean of any debris or dust. Apply the first coat like the primer, across, down, and across, beginning at the top edges. Instead of using a heavy coat, apply a thin layer and keep the surface as level as you can. It will make the finish line and aid station runs more difficult.

Ensure you pay attention to pain in tight areas as it dries. You can use a brush to remove any excess paint from tight spots during the drying process. After the first coat is dried well,  paint the subsequent coats.
