When using a drywall lift for installation, it is essential not to hang the panels vertically. When hung vertically, it does not allow you to hide any uneven studs behind the wall, which could cause an unsightly seam or bump in your finished wall. If multiple panels are used in one area with any unevenness present, this could cause an exaggerated seam that would be difficult to repair once completed. Hanging horizontally allows you to better correct any imperfections before adding joint compound so that it results in a professional-looking job when finished.
