Feedback requested: how can I save this and waterproof it?
Ok new guy is underway, and here is a photo of his work. I posted previously and you guys pointed out a lot of issues that I couldn’t see. Posting the update photo of the new guys worknew photos .
From what I can tell the job just looks a 100% times better, even tile, decent spacing etc. but he has not water proofed it.
Is there any way to waterproof this without tearing out all the floor tile again?
