All-Purpose Drywall CompoundĪll purpose drywall compound is likely the most common and is very popular with do-it-yourselfers. Working in tandem, these two can follow each other while working simultaneously. Taping compound is common on professional projects because the tape setter and the top coater are often two different people. Taping compound contains coarse gypsum not suitable for smooth finishes. Taping drywall compound is fairly coarse and is great for setting paper drywall tape. Generally, there are five main versions of drywall compound: Taping Drywall Compound However most drywall compound comes premixed for a specific application because it saves time for the drywall finishers. Drywall compound is available in powder form, which you just mix with water. What Are the Different Kinds of Drywall Compound?ĭrywall compound is a mixture of gypsum and water, and is available in different consistencies for different applications. Level 5 drywall finish is common in structures with strict lighting conditions, like art galleries. Level 5 drywall texture is suitable for matte, semi-gloss, and high-gloss paint sheens. In effect, this skim coat covers all visible imperfections and results in a visually perfect surface. Level 5 drywall finish takes level 4 and adds a skim coat to the entire drywalled surface. Level 5 drywall finish is the smoothest finish possible. Ceiling paints work to reduce the light reflections that could illuminate these defects. Unlike a wall that may include artwork or windows, ceilings tend to be large and flat, so waves or other defects in the ceiling drywall are amplified. Ceiling paints are designed for ceilings because ceilings tend to be very large, visually unbroken spaces. Level 4 drywall finish adds a second coat to all the fasteners as well.īy the way, this is why ceiling paints are usually flat or have a very low sheen. The pros recommend using a paint that reflects little light on a level 4 drywall finish, which would be flat or eggshell, to hide the tiny imperfections in the finish. Shiny paint reflects light quite well, emphasizing shadows and detail. Level 4 drywall finish is recommended for surfaces to be painted with flat or eggshell paint. Level 3 drywall finish is typical for walls destined to be textured or covered with a covering, like wallpaper. Some drywall tape, like fiberglass, is self adhesive and does require the additional compound for adhesion, but it is applied anyway in a level 3 finish. Level 3 drywall finish adds another layer of drywall compound and imbeds a layer of drywall tape over the joints. Level 3 drywall finish is what most of us have in our homes. Level 2 drywall finish will only appear where it can be seen, so level 2 drywall finish will not include any other areas, like behind appliances or tile. In a level 2 drywall finish, the fastener heads are also addressed and covered with drywall compound. Level 2 drywall finish adds another coat of drywall compound in an effort to make the surface even smoother. Known as a plenum space, this area can spread a fire due to air circulation, so the tape and compound are applied to any joints to prevent air from passing between the panels. Many commercial buildings use the space above the ceiling for air circulation instead of separate vents. Drywall has excellent fire retardant properties, but fire can spread anywhere air can pass. You may wonder why the installer would even bother with one coat if the public will never see it. The fastener heads are ignored in a level 1 finish. Level 1 includes one coat of drywall compound (known by the professionals as mud) and tape in all the inside corners ( corner bead is used for outside corners). Level 1 drywall finish is common in areas that need drywall and sealing, but are never seen by the public. In non-public, non-plenum areas like a barn for example, finishing would have no practical effect. Sometimes drywall is installed simply to separate interior spaces and is only functional in nature.
