Hello there,

If they are Polystyrene tiles. they should be removed. If you don't want to do that or can't then, Maybe fix a Metal look tile over the joints where 4 tiles meet. either in lone or like a diamond. Use a trellis around the outside and paint it. Wood Panel it in what ever design you like. Cover it with Shiplap. Best wishes.

We’ve done tons of DIY ceilings - maybe one of these projects appeal to you: https://www.frugalfamilytimes.com/category/crafts-and-diy/ceiling

Here's a post that might help - https://www.hunker.com/12367077/ideas-for-covering-up-old-ceiling-tiles

I've used paint.

You can certainly paint it though I'm sure Hometalk has a bunch of great ideas. Try the search bar at the top left and I'm sure you'll find some good inspiration.

If it is a metal tile you can frame it for wall decor.

I would totally paint it personally :)

Do you want to keep the tile ceiling or are you wanting to cover it with another surface?
