I want to use 1/4" backer board behind my wall tile. Is this OK?

I see 4x4 sheets that are 1/4 " that say use under tile as underlayment Floors I want to put it on the walls, in a 4 x 8 area. The support behind would be firm. Is this ok?
Asked by: JERRY
You can use the 1/4" backer on the wall. You will need to use horizontal blocking on the seams if it is going directly to the studs

How will this product work for a pier and beam shower house?

Asked by: mom6
Cannot say. It depends on if the subfloor meets the minimum deflection criteria per the tile manufacturers requirements.

HardieBacker 1/4 in. x 4 ft. x 8 ft. Cement Backerboard is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from Good for tiling larger area Excellent backerboard for larger areas. It is slightly cheaper than the 3x5's, but downside is they don't come with the grid lines like the 3x5 do.

Rated 4 out of 5 by from Amazingly tough! The 4' x 8' sheets are amazingly tough- I expected to break a few of these sheets by accident, but so far not one has busted! Even when picking up by one corner, this stuff stays together. Bonds extremely well with grout and makes a solid subfloor base.

Rated 4 out of 5 by from Great for doing large areas Goes down much quicker than 3 x 5 sheets, will have less seams and overall costs less. A little more difficult to handle but when doing large areas this is the way to go. Only drawback is it does not have the preset marks for where to install screws but a chalk line and a little bit of time one can prep all for 6" on the edge and 12" in the field.
