I started adding trim to our dining room. I only bought one piece of trim from Lowes to test it out. The cost of one 8 foot piece was about $3. I was really nervous about installing it. We don’t own a nail gun and I wasn’t sure I wanted to rent one just for one piece of trim. I started by measuring out the room and deciding how many squares of trim I wanted on each wall. I decided on four inches of trim between the base board, chair rail and each box. This helped me determine how big each box would be. I started with the main wall. It measured 139 inches long. I took into account that I wanted four inches from each wall and between each box and I wanted five boxes, which equates to 24 inches needed for spacing. 139-24 = 115 divided by 5 boxes equals 23 inch wide boxes. I did the same for measuring from the base boards to the chair rail. Here is a good tutorial on measuring.
Here is the test drive wall. The finish nails that I used were rather easy to hammer in without a nail gun so I don’t think we will be renting or buying a nail gun for this project. Now crown molding we plan to add to rooms in the future, hello nail gun.
