What is the preferred method for attaching MFD shelves?

The preferred method for attaching MFD (Medium Density Fiberboard) shelves is through dados and glue.

Using dados provides structural integrity to the shelf as it incorporates a groove or channel cut into the side panels, allowing the shelf to rest securely within this space. This design not only offers a stable support for the shelves but also helps in distributing weight evenly across the surface. The addition of glue enhances the bond between the MFD shelf and the sides, preventing shifting and increasing durability over time.

In contrast, other methods, such as brads and glue or pre-drilling for drywall screws, may not provide the same level of support and strength. Biscuits can also add stability, but they do not offer the same robust fit as a dado joint, which is specifically designed for shelving purposes. Therefore, dados paired with adhesive are recommended for ensuring the longevity and stability of MFD shelving.
