Shiplap siding is a uniquely designed wooden siding material that has a 1/2-inch overlap built into it. This type of siding works much like a tongue and groove wooden floor as it forms a tight seal between two pieces. It can be installed either horizontally or vertically for adding character and detail to your home.

By following the steps in the first two installments of this series you learned the preliminary steps and how to lay the first plank. In this part you will now be able to finish the project by laying out the rest of your shiplap siding.

(This is Part 3 of a 3 part series. To return to Part 2, click here.)

Step 1: Finish off Bottom Row

Using the same techniques of laying out a bead of caulking along the outer edge and pre-drilling the nail holes to keep the edges water tight and the planks from cracking, finish the bottom row of siding. Keep the level on top of each of the boards to ensure that each successive row will also be level.

Step 2: Make Square Cuts

As you get to the last plank on the bottom row you will need to cut it to fit. Set the plank on the wall and mark it where you need to cut it. This will be much more accurate than measuring and then transferring it to the plank. Once you have the mark, set the plank on the saw horses and use your carpenter's square to keep the line straight and square. As you cut, use a chop saw, or a circular saw with a straight edge.

Step 3: Mark for Next Row

Once the first row is done you will need to lay out a chalk line for the second row. This step will need to be repeated for each successive row after until you reach the top. This chalk line is to ensure that each row will be overlapped with the exact measurements it needs. Start the line on the top edge of the first board until it reaches the end. Measure down 1/2 inch from the top of the board and snap the line. Make sure there is a consistent 1/2 inch along the entire length of the row.

Step 4: Start Installing Siding

Once the first row is completed, and is marked for the second, you can then start the process of covering the entire wall with the shiplap siding. Be careful to take the time to follow each procedure of caulking outside edges, making square cuts, and pre-drilling holes.

Step 5: Keep Staggered Joints

A major mistake of many people is to just start with the longest board and keep going until you have to cut one to fit. You should stagger the end joints, like you would with a hardwood floor. Cut so the joints end up in the middle of the plank below it.

Step 6: Cut Around Windows and Doors

When you come to a window, or a doorframe, you should cut the plank to fit with a jig saw. As you get close to the obstruction you need to work around, stagger the overhang a little so it does not land in the middle of the plank.

Step 7: Finish with Caulk

Once you get to the top of the wall you should leave the top of it open. Use a bead of caulking to seal it from the weather.
