q & a
-
When installing USG Durock® Brand Cement Board Panels with EdgeGuard, does it matter which side faces out?
No, it doesn't matter. Regardless of which side faces out during installation, you can still expect the same great performance that professionals and do-it-yourselfers have come to expect from USG Durock® Brand Cement Board.
The purpose of the dual surfaces (one smooth side, one textured side) on USG Durock® Brand Cement Board is to better receive mastic and thin-set mortar. The smooth side is ideal for mastic applications, as it increases adhesive coverage. The textured side is ideal for mortar applications, as it enhances bonding and reduces tile slip. That said, mastic or thin-set mortar can be used on either side of the board without compromising performance.
