3. 4

4. 6

The correct answer is: 5

The levels of gypsum drywall installation are typically recognized to ensure that the finished surface meets the desired quality and readiness for painting or other finishes. The Gypsum Association outlines five distinct levels of drywall finishing, which are specified to accommodate various degrees of visual quality. Level 1 is often used in areas that are not going to be seen, such as above ceilings or in mechanical rooms. Level 2 is used in areas that do not require a high-quality finish, such as in garages and storage areas. Level 3 is appropriate for areas that will receive a light texture or wall coverings. Level 4 is intended for walls that will be painted, requiring a higher quality of finish, while Level 5 provides the highest quality of finish and is suitable for surfaces with critical lighting conditions, ensuring minimal imperfections are visible. These five levels guide drywall contractors and designers in choosing the appropriate finish for different applications, which is essential for achieving the desired aesthetic and functional results in interior spaces.
