First off I'm no carpenter & know very little about home repair.I'm
replacing the floor in my bathroom in an older home that the has rotted
out.I'v replaced all the 2x6's and
braces with new pressure treated stuff. My bath room is 12ft long x5ft
wide.I would like to know now if it is possible to use cemenyt wallboard for
the flooring without subflooring under it.Since cement is not flexible would
it tend to crack when walked on & does it need special fastners to attach it
to the 2x6's also how do you make the openings for the comode,waterlines &
etc.If this is possible since the cement panels are 3x5 to what would the
spacing on the 2x6's on the the 3ft width need to be ?
I hope I.v explained this enough for someone to tell me the best things to
do.If this is not enough info I will try to answer any questions I can.All
help is GREATLY appreciated
I have no pratical experience but cement while having good compressive
strength, has poor tensile and flex strength. This is why they add rebar.
I would not use the wall board for flooring which will flex and most likely
You must have a subfloor. I'd strongly suggest getting a book, either
online or though your local library (they will have this book), by
Michael Byrne - Setting Tile. It's a thorough workup, way more
information than you'll probably need, but it's well written and a
beginner will understand it. Another excellent book is Renovation by
Michael Litchfield. You'll save yourself a lot of headaches if you
understand the process from start to finish. Tile work and bathrooms
pay big dividends for taking care of the the construction details
correctly from the start.
