Spray painting windows: How to refresh your window frames & sills
How to Spray Paint Windows
Start by sanding the window frame using medium grade sandpaper and remove all dust. Using a damp sponge, wipe the frame clean. Use masking tape to ensure a clean line, removing and reapplying it between coats.
Apply the paint to the frame then leave the window open, allowing the paint to dry. Once the first coat has dried, lightly sand the first coat. You can then apply a second coat, removing the masking tape along the way. Leave the paint to dry once more.
If you are painting a casement window, start by painting the frame, leaving the window sill until last. For sash windows, begin at the bottom frame. Once it has dried, move the frame up and paint the other frame. Leave the paint to dry for 24 hours.
Painting Window Sills
Make sure your window sill is adequately prepared before painting. Prime the window sill using primer and an angled brush so that any ridges or nooks in the woodwork are covered. Alternatively, a spray painter will do the job just as well, if not better, by ensuring that the entire surface if covered.
Once you’ve left the primer to dry thoroughly, begin painting your window sill using long smooth strokes. Make sure you’ve chosen a paint that is hard-wearing and easy to clean. Once dry, give your window sill another coat if needed and allow to dry once more.
Do You Paint Inside Window Sills?
Yes, it would be best if you painted inside window sills when decorating a room. Especially when other parts of the room are painted, such as the skirting boards or the window it’s self.
Leaving this area unpainted will look odd and may ruin the appearance of your room. If you’re afraid to not get the job done correctly, feel free to get in touch with us to discuss your situation or directly get a quote here.
How to Paint Exterior Window Sills and Frames
When spray painting window sills, make sure to use masking tape around the edge, so the paint doesn’t drip onto brickwork. Then follow these steps:
- All sills and frames need to be cleaned before painting.
- Clean them thoroughly using warm water and washing up liquid.
- Rinse everything down once again and allow to dry thoroughly.
- Remove any mould and flaking paint using a putty knife.
- Fill in any cracks between the glass and frame.
- Sand the frame down and clean everything up after.
- Finish by applying a coat of water-based primer and allow to dry thoroughly.
- Apply two coats of paint using a quality brush or paint sprayer.

Best Paint for Window Sills
The best type of paint for window sills tends to be latex or oil-based paint. Decide whether you want to achieve a gloss or satin finish. We don’t recommend flat enamel paints for window sills as they tend to attract dirt.
From here, it’s just a case of choosing the right paint colour. If you already have a brand in mind, look at the swatches available to help you make your final decision. Visit our trade counter or online shop to discover the paint colours we offer.
What Type of Paint for Window Frames
There are two main types of paint available for painting window frames. These include solvent-based (alkyd) or water-based (acrylic). Ideally, try and use the same type of paint that you are covering.
However, if you’re painting bare wood, the best type of paint to use is acrylic outdoor paint. Acrylic paint allows the surface to breathe, ensuring the best adhesion no matter the weather.
Best Paint for Exterior Wood Windows
Latex-based paints tend to be best for painting exterior wood windows. They dry quickly, and latex expands and contracts when the temperature changes.
Be aware, however, that latex paint isn’t suitable to apply over oil-based paint because it could bubble and peel in future. We recommend a gloss paint for outdoor use as they are easy to clean and are resistant to damage.
Exterior Window Paint
There are several different paints available to paint the exterior of windows. To paint brand new windows that have never been treated, we recommend acrylic paint which allows the wood to breathe and won’t peel as quickly.
However, other solvent or water-based paints can be used as well. Try and use the same type of paint to cover the existing coating for best results.
