Assemble and Install Shelves

What happens here

For each shelf, apply wood glue along the edges of the plywood pieces that will form the top, bottom, and front of the floating shelf box. Use a brad nailer with 1-1/2 inch brad nails to securely fasten these pieces together, forming a hollow box. The video shows a reinforcement piece being added to longer shelves to prevent future sagging. Once assembled, carefully position each shelf box onto the previously installed wall cleats. Secure the shelves to the cleats using wood glue and additional brad nails.

Goal: Apply wood glue and use a brad nailer to assemble the floating shelf boxes, then carefully install them onto the wall cleats, securing them with brad nails.
