We lined up the boards to see what & where we needed to cut.
Step 2: Tapped the walls looking for joists to nail it against. (were unsuccessful so decided to use No Nails)
Step 3: Meausure the boards.
Step 4: Mark on boards for cutting.
Step 5: We used simple hand saw to cut.
Step 6: No Nails or nail gun
Step 7: Allow No Nails to dry briefly until tacky and push to wall, hold in place.
That’s it. It really is that simple!
Let me know if you try it yourself, I’d love to see pics
