What paint to use?

You could use an oil-based paint which will last longer but be aware, it won't last forever. You can try sealing it too to try and extend its life.

I agree completely with Becky's advice.

I also agree with Becky. Oil based paints are a little harder to work with but will give you the longest lasting option for outdoor use. Just make absolute certain that you let it dry completely (oil based paints take longer to dry) before exposing it to the elements.

Yes! Totally agree with using an oil based paints.

Here is some info Patricia

Thanks everyone!!

Exterior house paint and seal.

Oil-based paint creates a stronger and more durable finish, making it an excellent choice for exterior paint projects. The downsides are that they take longer to cure than water-based paints, are oftentimes mixed with harsh chemicals, and also emit VOCs (volatile organic compounds). Oil-based paints do have a tendency to crack and yellow over time, especially when used on wood siding, which expands and contracts with the weather.

Oil-based paints used to be the go-to choice for exterior projects for many years, but the recent technological advancements made in water-based paints makes them the overall better choice. Acrylic paint is the most durable of all. It’s long-lasting, flexible, and able to withstand fading from the sun or damage from rain and other elements.

Nothing you use will last forever if your window is out in the elements. I never use oil for anything because it's nasty clean up and not good for the environment. There are great acrylic and latex options for exterior use these days. I would check them out at your local paint store.

Any paint will work but not last forever. You can seal the paint with clear sealer to extend the lasting time. You can use clear spray paint to seal. Oil based will work but not easy to work with. Latex paints or acilic paint will also work and are easier to work with. When I was in grade school in the 60's we used to paint store windows for Halloween. The best three paintings won a prize. We used latex paints back then. They lasted for the whole month of October until they were scraped off and remaining was washed off.

Yes, go with the oil based paints, they will endure all kinds of weather, but not forever.

Use an exterior, oil-based paint.

Oil based exterior grade paint will work best

Hi Patricia, at least three types of paint may be used on glass: acrylic enamel, acrylics marked as suitable for tile or glass, and specially formulated solvent-based paints.

I have a lot of luck with Fusion Mineral Paint. You can paint on glass and you can use it outdoors. I would put a sealer on it for outdoors as well.

Hi Patricia, perhaps you can consider using glass etching instead of paint? The effect will be more subtle but last longer.
