When you've got an air pocket or some sure location as part of your floor that is not degree or flat With all the encompassing spot and you just screw your backerboard onto it this will make a weak place in the floor.

The backerboards will likely not noticeably diminish that movement. This needs to be resolved by altering your floor joists and framing – not by including things on top of them. In the event your floor is bouncy without the backerboards it will however be bouncy with them.

In the event the tile you're laying isn't too closely textured to the back again side or irregular, the exact same 1/4" sq. notched trowel ought to suffice.
