Preparation for Attaching the Countertop

Before attaching the wood countertop to the cabinets, it is essential to prepare both the countertop and the cabinetry. Begin by ensuring that both surfaces are clean and free from dust or debris. This will promote a better bond and prevent any potential damage during installation.

Gather the necessary tools and materials:

  • Wood glue or silicone adhesive
