Hello,

I just started a small project to regrout tiles in my balcony (outdoors). As I removed old grout, some tiles came off and I want to put them back. The problem is the old cement based tile adhesive is still on the back of these tiles and hard to remove. If I use a cement based tile adhesive directly, these tiles will be on a higher level than other tiles.

Any suggestion on a reliable tile adhesive (possibly non cement based) or how I can remove the old tile adhesive?

Thanks in advance.
