Kitchen tile backsplash. Should I use oil based primer or water based

Use a tile paint kit. Rustoleum or Homax. Has everything you need.

I don't think it matters as long as the drywall is sealed. Water based is easier to clean up and dries faster. it will all be covered anyway.

I would use water base

Stay away from oil based. Water based is mush easier to work with.

The drywall needs to be sealed against water, mold and mildew. Then paint in any good paint. Chalk paint has some texture, so small tiles (1”sq) might have a problem. Sheets of tiles or larger tiles may stay more securely because there is a surface to hold onto. Your water-resistant grout will do more sealing, then the trimming caulk. I would use water-resistant, dirt resistant, grease resistant paint—in other words, plastic! Best wishes ☺️

Hi there, my preference would be a water-based primer. I've never had much luck with the oil-based ones.

Are you wanting to tile over the splashback or paint it ?

The biggest advantage of oil based primer is better at sealing in stains.

I am also a supporter of water based. I removed a few stains on my shirt that I bought on the last sale with it easily.

Another vote for water based.

I'd go with wter-based paint.

Oil based primer is usually used outdoors.

Use water-based primer when you want to reduce the amount of VOCs and when you plan to use water-based or latex paint on top.

Water-based primer is easy to clean up. You don't need any special mineral spirits or paint thinner - wash the brushes in water and you're ready for another day of painting!

If you're in a hurry, water-based primer is fast drying. Once the water in the product evaporates, the primer is dry. This means you can probably begin painting your first coat of latex paint on the same day.

Hello, hope this helps you out.

Water based should work just perfectly for this application
