Can I paint a vinyl backsplash?

Clean it well. Prime with Kilz primer then paint. Being primed any paint will work.

Yes as long as it secure to the wsll.

Do yourself a big favor and don't paint over wallpaper.

Make sure that you prime with a primer rated for vinyl. You might also like the stick-on vinyl backsplash, it has the look of glass tiles.

Thanks. I've used peel and stick before. Because its a seasonal trailer with winters pretty cold, I didnt think that would stay on very long. Will try painting first. Thanks again.
