In gypsum drywall finishing, Level 3 is specifically intended for surfaces that will be finished with heavy or medium textures. This level of finishing entails a taping and finishing approach that creates a surface suitable for applying texture materials. The texture itself can help to disguise imperfections in the drywall, making Level 3 the ideal choice for spaces where a durable finish is necessary, such as in commercial environments or high-visibility areas.

Levels of drywall finishing are standardized, and each level serves a different purpose based on the aesthetic and functional demands of the space. Lower levels, such as Level 1 or Level 2, would not provide the suitability needed for heavy texturing; they are often intended for areas like mechanical spaces or surfaces that will not be seen. Level 4 is smoother and generally used for painted surfaces without texture, so it does not align with the requirement for heavy or medium textures either.

Therefore, Level 3 stands out as the appropriate choice for achieving the desired effect in heavy or medium textured finishes in gypsum drywall.
