When cutting wallboard, which side do you score first?

When cutting wallboard, it is essential to score the smooth side first. The smooth surface is designed to allow for a clean cut. This side typically has a backing made of paper, which facilitates easier scoring and snapping of the board. When scoring it, you use a utility knife to create a shallow cut along the desired line, and then the board can be snapped along this cut for a clean break.

Choosing the rough side for scoring would lead to a less precise cut, and inaccuracies may occur due to the texture and composition of the material. Thus, scoring the smooth side helps achieve a more accurate and professional result, ensuring that edges remain neat. This practice is not just about convenience; it significantly impacts the quality of the finish and the overall effectiveness of the installation.
