Determine the location where you want to mount the shelves. Measure up from the floor and make a pencil mark on the wall at 16 inches, 32 inches, 44 inches and 52 inches.
Place a straight edge on each of the marks and put a level on top. Center the bubble of the level and then draw a 48-inch line along the straight edge.
Place a shelf bracket 12 inches in from the right end of the lowest line. Mark the bracket holes onto the wall with a pencil. Repeat, 12 inches in from the left end. Drill holes with a carbide-tipped drill bit at each of the marked locations. Insert masonry wall anchors into the holes.
Line up the bracket mounting holes with the wall anchors. Insert screws through the mounting holes and into the anchors. Tighten them with a screwdriver.
Repeat the previous two steps on each of the three remaining lines.
Place a wooden shelf board onto the brackets, starting at the top. Insert a screw into the hole in the bottom of the bracket and screw it into each board to keep the shelf boards in position.
