How do you score backer board?
Just so, which side of Hardibacker do you score?
when you score drywall you snap away from the scored side. In the hardibacker directions it says to snap TOWARD the scored side.
Likewise, people ask, how do you cut small pieces of cement board?
Lay your cement board flat, and draw a line with a carpenter's pencil where you intend to cut. Then, place a straightedge along the line and drag either a drywall utility knife or a scoring tool against it. Repeat your cuts two to three times to make them deeper, which will make snapping the board easier.
