1. Assess Your Cabinet's Underside

Before diving into the installation, take a moment to look at the underside of your kitchen cabinets. Often, this area is neglected and may have a different color or a small cavity. It's essential to understand what the underside will look like when your project is complete.

You'll apply a skin panel to match the paint color, ensuring it aligns flush with the bottom of the cabinet's face frame. To achieve this, you'll need to trim the plywood sides and back by 1/4".

Here's a tip: As a beginner, it might be helpful to assemble the cabinet first, marking where the 1/4" needs to be trimmed.

3. Filling the Cavity

Many kitchen cabinets have a cavity underneath. To bridge this gap, install bottom spacers. These spacers will create a uniform surface for the skin panel installation.

4. Scribe Molding Installation

It is at this step when the side skin panel will be applied. The scribe molding needs to cover the bottom of the side skin panel. This eliminates a plywood edge.

Scribe molding is a crucial element in the cabinet's underside finish. It not only conceals any exposed plywood edges but also gives a polished appearance.
