My tiles are in good shape except there is space in between then after 25 years. I want to paint over then but what can I use to fill the gaps between the tiles?

Hi patty, I answered this question yesterday. I wouldn't advise painting over, you will never get them clean enough for the new paint to stick for any period.

Thanks! I decided to tear them out since a few were lifting under the fridge. Now I wish my kitchen wasn't so big!
