Siding Your Garage
Measure along the length of the garage walls that you wish to side, marking off every 16 inches and putting a mark there. When you are done go around the garage and count up your marks.
Measure the height of your garage and write it down.
Go to your wood or lumber location and get 1 1/2-inch thick wood strips the same height as your garage that is 4 inches wide and the total number of pencil marks that you made.
Repeat step number three when buying your firring backing.
Clean the sides of your garage with a mild detergent.
Begin putting up your firring backing at your check marks you made earlier. Use your level to ensure a straight fit then using concrete screws put one screw in the firring backing at every 12 inches of the length of the firring backing beginning at the top and ending at the bottom.
Nail your 1 1/2" thick wood strips directly to the firring backing in the exact same manner using the 3 inch nails.
Using your measuring tape measure out 18-inch wide sections of your insect screen and cut. Depending on the length of your insect screen you may have to overlap sections.
Nail the insect screen to the wood strips with the 1 1/2inch nails so that 1 inch is overlapping each side of the wood strip.
Nail insect screen to the top, bottom and sides of the wood strips.
Install your siding to directly to the wood strips with the siding nails and following the instructions of the manufacturer.
