Seal between hardibacker floor.
Although most backerboards currently available won t fall apart when exposed to moisture and are somewhat water resistant they aren t waterproof.
The corners and edges of the sheets should not touch one another.
Push the mortar through the mesh tape and into the 1 8 inch space between the backer board and the drywall.
Whether you re laying down a new tile floor or installing a shower you may use a sheathing material such as backerboard.
Run the drywall knife over the mortar to create a smooth finish and remove any excess material.
Thank you once again for your invaluable help.
Take a trowel or a taping knife and use it to apply the thinset to the gap.
Backer board by strip of ditra underlayment mesh tape joining strip of underlayment to backer board thinset kerdiband more thinset leg of shiene tile edging thinset and finally tiles.

You need to make sure that the entire gap between the boards is filled up with the thinset.

It is the material that you use underneath the backer board to attach it to the wood subfloor.
Seal narrow cracks with paintable or clear latex caulk either at the top or along the bottom where the baseboards meet the floor.
Leave a 1 8 inch gap between each backerboard sheet.
