When it comes to finishing drywall, there are various levels of quality that can be achieved. These levels are defined by the Gypsum Association, a trade association in the United States that represents manufacturers of gypsum board. Each level dictates the amount of finishing work that is required to achieve a smooth and even surface. Understanding these different gypsum board finish levelsgypsum board finish levels can help ensure that your project meets the desired outcome.
Level 0 is the most basic level of finish, and it involves simply taping the joints and applying joint compound to cover the seams. This level is typically used in unfinished spaces where the drywall will not be visible, such as in garages or attics. Level 0 provides a rough and uneven surface that may require additional work if a more finished look is desired.
Level 1 is a step up from Level 0 and involves applying a coat of joint compound over the tape and screw heads. This level is commonly used in temporary construction or in areas where the drywall will be covered with a texture or other finish. Level 1 provides a smooth surface that is suitable for painting but may still show some imperfections.
Level 2 is the most common level of finish for residential construction. In addition to taping and mudding the joints, Level 2 requires a second coat of joint compound to cover the tape and screw heads. This level provides a smooth and even surface that is ready for painting. However, some imperfections may still be visible under certain lighting conditions.
Level 3 is a higher standard of finish that is often used in commercial or high-end residential projects. In addition to the requirements of Level 2, Level 3 involves applying a third coat of joint compound to cover any remaining imperfections. This level provides a smooth and uniform surface that is suitable for most paint finishes.
Level 4 is an even higher standard of finish that is typically used in projects where a very smooth surface is desired. In addition to the requirements of Level 3, Level 4 involves sanding the joints and applying a skim coat of joint compound to achieve a level 5 finish. This level provides a near-perfect surface that is ideal for gloss or semi-gloss paint finishes.
Level 5 is the highest standard of finish and is reserved for projects where a highly polished surface is required. In addition to the requirements of Level 4, Level 5 involves applying a second skim coat of joint compound and sanding the surface to remove any imperfections. This level provides a flawless surface that is suitable for critical lighting conditions.
