What is Drywall?
Drywall is the result of the evolution of the building industry. For thousands of years, plaster made from lime, sand, animal hair and other ingredients was used to create a smooth interior finish. Later, it was discovered that gypsum dried faster than lime, so gypsum became the main ingredient in plaster. It wasn't until well into the 20th century, though, that sheets of plasterboard began to replace traditional wet plastering.
Today, drywall comes in standard sizes and thicknesses. The drywall sheets used in Australian homes are usually 2.4 metres long by 1.2 metres wide - the same as a standard sheet of plywood or particle board. The sheets are heavy and brittle and care must be taken when handling them. Straight cuts can be made in plasterboard simply by scoring through one outer paper layer and snapping off the unwanted excess.
Drywall is applied to walls and ceilings using special drywall nails or screws, which penetrate the gypsum without shattering it and hold the heavy sheets firmly with their wide heads. Drywall nails and screws are sunk just beneath the surface of the drywall. After it is installed, the indentations and seams are filled using special plastering products applied with a trowel.
Choosing a drywall installer
Professional drywall installers make their job look easy, but that's because they do it every day. If you need drywall for anything , it's better to let the pros do the job for you. Aside from having the expertise to create a smooth finish, professional drywallers know the best techniques and materials to use in any given situation. Wet areas, for example, require special products and techniques.
