What is your opinion regarding placing flexbond thin set over vinyl floor and putting hardiboard on top?

I currently have 3/4 inch tongue and groove plywood nailed and glued to 2x10 @ 16 inch spacing followed by 1/4 inch lauan plywood followed by sheet vinyl glued to lauan. Sheet vinly is in good condition. I would like to place flexbond thin set (Home Depot) on top of the sheet vinyl followed by 1/4 inch hardiboard followed by flexbond thin set and then 12" by 12" tile. Grout would by pure portland cement. Any problems with this?

Lowes carries Laticrete thin set that you add their additive (333) to it. Would you recommend the flexbond or laticrete?

Thanks in advance for all replies

Most pros do not think it is a good idea to do because there can be so many variables that come into play. The vinyl cannot be cushioned, it has to be 100% adhered to the floor, and of high quality so it does not shrink. Also, whats under it plays a large part in how successful the tile install will be. In your case the luan is the deal breaker. Luan is too soft of a material and has too much give to be in subfloor under ceramic tile. The compression of luan under a point load, like that of a wheel on a refriferator, had led to many tile failures in the past. Cement board offers no structural strength and will allow the movement in the luan to transfer up to the tile. The cement board should be used after the vinyl and luan are removed as it is a top grade surface for bonding of thinset.

The vinyl and luan can be removed together by using a circular saw to cut just below the depth of the luan. Make 2' squres and lift with a prybar. Many staples will be left behind as the luan is so soft the staples will tear through the board as it is being lifted. Use pliers or such to pull them or hammer them back flush intot eh plywood subfloor.

When setting the cement board put the thinset under the board and anchor with 1 & 1/4" galvanized roofing nails or backerboard screws. Tape all the board seams with mesh tape and a thin coat of modified thinset.
