Grab the tape measure and measure the wall's height. Divide this number by the height of the log wall panels. This will be the number of panels you need.
Measure the width of the wall and transfer this measurement to a log wall panel. Make a mark with a pencil to define where it should be cut.
Cut each piece of the panels with a saw and smooth away sharp edges with your sandpaper.
Apply a construction strength adhesive to the wall panel and place it at the bottom of the wall.
Drive a screw into every end of the panel with your power drill. Install every panel until you reach the top of the wall.
Apply caulk over any gaps between the log wall panels and over the screw holes as well.
