Wonderboard Installation
Posted by Ron on December 11, 19100 at 11:40:24:
Is it possible or advisable to install Wonderboard directly on to concrete blocks without using a furring strip? I would use a vapor barrier between the blocks and the Wonderboard, and I would use cement screws to fasten the board to the blocks. Any suggestions or recommendations for applying Wonderboard in this fashion. BTW, the application will be used for a ceramic tile shower. Thanks
