Using the Quad Lock Adhesive Wall Mount is easy. First, clean the surface where you want to mount it with an alcohol - based cleaner. This helps the mount stick better. Then, take the mount and remove the red backing paper from the 3M VHB self - adhesive. Stick it firmly on the clean, dry, non - porous surface. When you want to attach your smartphone, just twist it onto the mount until it locks. It's a quick and simple process. As for the screw option, if you want a more permanent setup, find a 6 - 8 gauge screw (you'll need to get this yourself). Drill a small hole in the wall and screw the mount in. For maintenance, keep the mount clean. If it gets dirty, you can gently wipe it with a soft cloth. Also, make sure the surface under the mount stays dry to prevent the adhesive from weakening.
