Over time, uPVC (unplasticized polyvinyl chloride) windows will deteriorate due to changes of outdoor temperatures. Replacing old, worn out uPVC windows is very expensive, but the good news is that you can paint them yourself. In order to get the best results, when repainting uPVC windows, try in hot weather.
Here are some materials and items needed and the steps.
For the items you will need is a sponge, primer cloth, brush, decorator tape, newspaper, exterior paint.
Clean the frame
First, clean the frame thoroughly. This is an important step so don’t rush into it if you want a really smooth finish. Remove dust and cobwebs with a clean cloth, brush, or dry sponge. Then, use warm soapy water and a kitchen sponge to remove grease and grime. Wipe dry with a soft cloth.
Use newspaper or masking tape
Apply high-quality decorative tape or tape to the glass to prevent paint splattering. You can also cover glass furniture and windows with newspaper for extra protection. If you get paint on the glass and don’t manage to wipe it off when it’s wet, simply wet the glass with window cleaner and remove the dry paint with a scraper, as scratching dry glass can leave streaks.
Use primer
After that, you need to paint the window frames with a primer. Many paint manufacturers claim that you don’t need a primer if you use their paint. But if you want a sturdy, long-lasting finish, a primer is the way to go. This is especially true for exterior uPVC, as the primer will ensure the paint is resistant to the elements.

Window frame paint
When the primer dries, paint the frame with eggshell finish for the exterior or gloss in a color of your choice. The paint can be water or oil based, but water based paint is definitely better. After the first coat of exterior paint has dried, apply the second coat. The only major issue you may run into is if you paint your uPVC windows a white or pale wood effect, as it may take more layers to stop the grain effect from showing.
Take off the tape
Remove the tape before the paint is 100 percent dry for a sharp line, and the painting process is complete.
