I was assuming that that would suffice before laying down my 1/2" backer board. So, are you saying that I need to add another 3/8" layer of plywood before I proceed with the backer board? Wow, looks like I was about to commit a grave error. Right? Thanks, your a Godsend. Patrick H. Hi Roger

I’m doing a small bath. I’ve layed down one layer of 3/4″ plywood over 16″ OC 8/4″X6″ floor joists. I was assuming that that would suffice before laying down my 1/2″ backer board. So, are you saying that I need to add another 3/8″ layer of plywood before I proceed with the backer board? Wow, looks like I was about to commit a grave error. Right?

Thanks, your a Godsend.

The seams of the backer, however, should be offset from the plywood seams by at least 1/3 the length of the backer. In other words with a 5 foot backer you need to place it overlapping the seam by at least 1'9". I try to overlap it by halves if possible, not always possible on larger floors. Hey Matt,

I am wondering if the the direction of the cement board should match the direction of the plywood. Does it matter? Should I avoid the alignment of plywood joints with cement board joints? (you mentioned not screwing into joists) Any help appreciated, thanks, Matt I have a new plywood sub-floor and will install Durarock on top of that.
