Apply First Layer of Adhesive

What happens here

Begin by applying a continuous, thick bead of Loctite Express Power Grab Heavy Duty exterior construction adhesive onto the bottom plywood layer of the sink basin. This adhesive is chosen for its instant grab and versatility, even working underwater, though its primary role here is to bond the plywood layers rather than provide a waterproof seal directly. Ensure the adhesive is applied evenly to create a strong bond between the layers.

Goal: Securely bond the initial plywood layers of the sink basin.
