What does reverse hang mean?
Reverse hanging is used primarily for textured, non-patterned wallcovering to eliminate visible shading differences on the wall. If the first strip is hung as it comes off the roll, the second strip would be rotated 180° and hung “upside down.” The third strip would be hung in the same direction as the first, then continue to rotate alternate strips. Working from two rolls sometimes cuts down on waste when matching patterns and allows you to pre-cut strips and match before pasting.
Reverse hanging wallpaper means that every other strip of paper is installed in the opposite direction from how it comes off the roll. If the first strip is hung as it comes off the roll, the second strip would be rotated 180° and hung “upside down.” The third strip would be hung in the same direction as the first, the fourth would be hung like the second strip, and so on. Reverse hanging is done to mitigate shading variances that can occur on a run of paper. It is only done when the wallpaper has no pattern.
