  • When installing USG Durock® Brand Cement Board Panels, does it matter which side faces out?

No, it does not matter. In the past, USG Durock® Brand Cement Board had a smooth side and a rough side that were used for different applications. Currently, USG Durock® Brand Cement Board is produced in such a way that it does not matter which side faces out.

For further instructions on installation, please review the Installation Guide and the Systems Guide.
