Drywall – Everything you need to know

drywall jobsWhat is Drywall?

Drywall are panel-like interior structures made by sandwiching a layer of gypsum plaster between similar sheets of paper-like material. The purposes it is most commonly used are for making walls in the interiors of building or supplemental ceilings below the brick and mortar roof of the house. These days drywall have become ubiquitous, and the de facto wall building process, having replaced the traditional lath and plaster walls a few decades back.

Why get Drywall?

The popularity of dry walls have a lot to do with its expediency in preparation. The lath and plaster construction process is tiresome and takes a long time, in most cases a week. Alternatively a unit can be dry walled in a couple of days by seasoned contractors.

Installation of Drywall

The skill required for drywall installation depends on the time of unit which requires construction, small homes can be dealt with by single carpenters, who have had prior experience. While large scale construction, mostly for commercial purposes, is more complex. The installation job is then divided between what in the profession are colloquially called as hangers and tapers. The former are tasked with installing the wallboard while the latter work on the joints and heads. The level of finish provided depends on the customer requirements.

A rather disadvantage of drywall are that they are not very pliable and thus need to be handled carefully when cutting down the required sizes of the sheets. Making holes for switches and any electrical outlets can easily be made using an electrical power tool called the keyhole saw. Once the panel is in the shape that you want it to be, the next part is installing the drywall on the wall structure. Commonly used mediums are drywall screws, fasteners and adhesives such as glue.

Drywall fasteners are being more preferred these days because they are a suitable replacement for wood and metal blockings that were used in in the drywall corners. Fasteners have made the installation process more simpler and cheaper, and along with that have made the tricky task of installing plumbing and electrical wiring though them incredibly easy.

After safely fixing the drywall to the wall or ceiling the next step is to hide the seams of the sheets using a specific tape, called the joint tape and lathering on a joint compound called mud. The mud has a multi-purpose use, and is often used to fill up defects such as cracks, to provide for a smooth and uniform finish. It is important to let the viscous compound properly dry up before it is painted on. Afterwards the whole structure is given a finishing coating with a finishing compound to make the whole wall look similar.

Advantages and Disadvantages of Drywall

A particular advantage of drywall, is that it effectively reduces the transmission of sound through the area it is installed on. Along with this it provides an additional insulating layer.

Unfortunately the structure also comes with a few disadvantages, such as being extremely susceptible to water damage and molding because of its composition.
