Joint Compound

Apropos of the protests
I was in Madison, Wisconsin during the dust-up over the collective bargaining rights of public employees. I wandered out unto the steps of the capitol building before sunrise. There were posters in the windows and a few people on the streets with signs in support of public employees.
The fervor over the budgetary demons compounded with the exclusion of police and emergency workers from the new bargaining rules gave the air of a political power play to the governor’s demands. That collective bargaining rights were eventually stripped in a vote outside of budgetary issues makes the political nature of the underlying motive all the clearer. The discussion, after all, wasn’t about whether unionization of public employes is a good idea, constitutional, etc or if a government has the power to dictate the rights of its employees; instead the narrative, even in the media, drew a false equivalency between fiscal solvency and public employee unionization.
I am, in many ways, unapologetically liberal and found myself discouraged that, during the fervor of the debate in southern Wisconsin, the nation missed an opportunity to ask why it is that we’ve become more and more prosperous while shrinking the middle class. I find the Occupy Wall Street protests encouraging because they represent the start of that discussion and the political counterpoint to the Tea Party. No movement deserves unmitigated support, and not all should be immediately understood in their demands.
The promise of our rights as laborers, citizens, and photographers are only as good as our resolve to honor those promises and demand others do the same.

tags Ready-mix lightweight joint compound

Ready-mix lightweight joint compound is a pre-made form of joint compound designed for fast application and easy maintenance. The compound is a complex combination of water, limestone, expanded perlite, ethylene-vinyl acetate polymer and attapulgite. This delicate mixture of compounds gives it a very creamy texture which allows it to spread onto surface with great ease.


Ready-mixed joint compound is most commonly used in hanging drywall for new or remodeled homes. Application is simple and easy, usually never taking more than three or four coats. When used for new walls, joint compound effectively eliminates all blemishes from the surface of the drywall, such as drilled in screws, hanging tape, or drywall tape. Joint compound can be used to finish gypsum panel joints, corner bead, trim and fasteners, as well as skim coating. In addition, it is also very handy for fixing minor blemishes or damages to walls. It easily patches up holes, bumps, tears, and other minor damages.

Ready-mix joint compound is usually more forgiving than the traditional form of joint compound. It can be used for as long of a period of time as needed, and does not dry up unless left unattended for a long period of time. Traditional “mix-it-yourself” joint compound usually lasts for one to two hours before drying. However, if it happens to set for more than a few hours, then you will need to apply water very liberally as needed to retain its soft texture.

Often referred to as drywall taping mud, joint compound is the primary material used in the drywall industry by a tradesperson, or applicator, called a “taper” or “drywall taper.” A similar compound is used in various ways as a sprayed-on textural finishing for gypsum panel walls and ceilings that have been pre-sealed and coated with joint compound. The flexibility and plastic qualities of joint compound make it a very versatile material both as sealer or finishing coat for wall surfaces, and also in decorative applications that range from machine sprayed texturing to hand-trowelled or even hand-crafted and sculptural finishes. In North America the application of joint mud and drywall tape sealer and trowelled joint compound on gypsum panels is a standard construction technique for painted wall and ceiling surfaces. Until more recently in North America, and through the world, several different plasters such as veneer plaster and “plaster of paris” have been used in a similar ways to joint compounds as fillers or for decorative purposes since ancient times, and the actual make up and working properties of these compounds is much similar. Modern ready-mixes or powder and water mixes are available in a wide range of styles from slow-drying to quick-drying to suit specific demands for use by contractors or decorators.

Health concerns

Joint compound mixes manufactured prior to the 1980s often contained a complex mixture of several substances. Among the additives used were asbestos fibers, which provided cohesiveness. Exposure to friable asbestos fibers has been linked to various health conditions, including cancer in some instances. Joint compounds manufactured from 1980 onward were required to have asbestos removed in favor of other compounds due to legislation to ban asbestos’ widespread use.
