Generally, painting is an interesting and effective activity. It transforms your aluminum window and door frames, offering them a new and great look as they've just been delivered from the manufacturer. 

When done right, your window frames will not only look good, but you will also be extending their lifespan. However, preparing your aluminum window frames and picking the right paint is vital for an excellent finish.

That said, here is a multi-step guide on how to paint aluminum window frames:


How to Paint Aluminum Window Frames


Painting your aluminum window frames doesn't have to be tedious or stressful. Here is a list of the material you will need and a how-to guide:


Material Needed 


  • Maskingtape
  • Acryliclatex paint 
  • Paintbrush
  • Primer(optional)
  • Finegrit sandpaper
  • Roller
  • Dropcloth
  • TSPcleaner 
  • Cleanrags 


First Step: Cleaning & Preparation  


Proper preparation is the key to productive painting sessions, even when it comes to aluminum window frames. 

Start by detaching hardware like door knobs, hinges, and screws from the door or window frame. You can also detach the frame from the window, allowing you to work on it away from your home. This will also help you focus better on your work. 

Nonetheless, if you can’t detach it, open your window and put the drop cloth or other shielding underneath it. 

Once you protect or remove the window frame, use a wire brush or sandpaper to take out any flaking corrosion or paint. Make sure you wear a dust mask and gloves to avoid breathing in the dust and debris produced while sanding out the old painting. 

When you remove the paint, wipe the aluminum window frame using a wet cloth to clear out any remaining dirt. 


Second Step: Applying Primer 


It is ready for prime once you have prepared and cleaned the frame. This is a critical step since it gives a reliable base for painting and is handy in hindering additional corrosion. Go for a Rust-Oleum aluminum-specific primer. You can always purchase it in your local home improvement shop. 

Follow the manufacturer's instructions when applying it. You can use a roller or brush to ensure the coat is even. Once you are done, give it time to dry before proceeding to the third step. 


Third Step: Painting the Aluminum Window frame


When the primer dries, your window frame is now ready for painting. Similar to applying primer, you can use a brush or roller specifically manufactured for painting metallic surfaces. You can find a roller or brush in your local home improvement store. 

It might be a good idea to pick a paint that's the same as your wall color so they'll match perfectly. Two coats of paint will be sufficient, but let the first one dry completely before applying the second one. Also, make sure to allow the paint to take as much time to dry as the manufacturer recommends.
