Hey guys, hope you can help me out. I have read up a little on this subject but I would like your input. Have a customer who wants her tile painted. Its outside but under her patio. Its in Arizona so it doesnt see much rain anyway. Could you guys give me some tips on prep, sealer and paint. She wants me to just primer it and paint, but I dont want to spend the rest of me life going back and fixing it over and over. Thanks for any info.
