Tape and Caulk/Seal Joints

What happens here

Apply blue painter's tape precisely along the edges where the assembled wood pieces meet, creating clean lines along the seams. Then, apply a bead of wood glue into these taped seams. The wood glue acts as a caulk to fill any minor gaps and create a smooth, seamless appearance. After applying, use your finger to carefully smooth the glue along the joint, ensuring it's pressed into the gap and excess is removed. Repeat this process for all seams on the mantel.

Goal: Achieve seamless, filled joints
