![]() ![]() Lightweight all-purpose mud is much less common in the US than conventional-weight mud and is fairly self-explanatory. ![]() Lightweight and Ultra Lightweight All-Purpose Joint Compound Most mixtures of all-purpose joint compounds instruct the user to, at minimum, allow each coat to dry overnight before adding an additional coat, sanding, priming, or painting. This means that more coats and more sanding are typically needed for a quality end result which makes all-purpose joint compound less appealing to those applying finish coats or filling larger seams, gaps, or holes. This type of mud is considered the jack of all trades in the drywall world and can be used at all stages of the process: to tape and fill drywall joints to skim-coat to add texture to wall surfaces and to apply a top or finish coat, though it does better at some of these stages than others.Ĭonventional-weight all-purpose mud is very sticky and forms a strong bond, but it does experience a fair amount of shrinkage and cracking as it dries, and it is more difficult to sand than other mud options. ![]() We’ll discuss the various types of mud and the differences between them in detail, below: “Conventional-Weight” or “Heavy” All-Purpose Joint CompoundĬonventional-weight all-purpose joint compound can be readily found in most big-box home improvement stores and neighborhood hardware stores in the US. Most mixture types have specific uses and methods for application that professionals in the construction industry are cognizant of, while other types of joint compound can act as somewhat of a catch-all for DIYers or are otherwise used for quick, less finicky jobs. Different Types of Mudĭrywall mud comes in a variety of types and is available either pre-mixed in buckets or powdered and sold in bags or boxes. However, in general, a thin, single coat of drywall mud should be allowed to dry overnight, or at least 12 hours, before sanding, adding another coat, and/or painting. The drying time for drywall mud varies depending on the type used, application thickness, humidity, and temperature. The application of mud creates a wall surface that is completely consistent in appearance and texture. When completely dry, joint compound can be easily sanded and shaped to create a smooth, virtually invisible transition between drywall panels or to add texture to a wall. This mixture is typically made from ground limestone, gypsum, clay, perlite, polymers, and water and hardens as it dries.
