| OK we all agree, that up the old self adhesive tile before it takes itself up. Like Art I am a huge fan of Mr. hardie's products like Hardibacker and Hardiboard. Be sure to use the special green screws they sell for Hardibacker, 1 1/4 ' screws for 1/4" boards and 1 5/8 for 1 1/2 " boards. Mud the seems with the same modified thinset you will use to set your tile and use fiberglass tape, I never do but Mr. Hardie likes it. |
