Today I removed all the dry fit tiles along with the cement board.. Cleaned up the floor and proceeded to mix and apply the thinset and screwed down all the cement board.. Gotta say my knees, back and legs are sore lol.. I could never do this for a living! The cement board will be inspected on Thursday and thinking I will add cement to tie the cement board to the chimney.. Added a pic to show progress..
