What is Drywall?
The majority of homes in the United States have drywall. Drywall, also known as sheetrock and plasterboard, is one of the most common building materials for homes, buildings, and businesses. So, what is drywall?
Before drywall, and for many years, wet plastering was used. Plaster was made from lime, hair, sand and other materials, which were mixed and splattered onto walls to create a smooth interior wall finish. Later, they discovered that gypsum dries faster than lime, so gypsum became the main ingredient in plaster. And many years later, sheets of plasterboard began to replace traditional plastering.
Today, drywall comes in standard sizes similar to that of plywood and particleboard. Plaster boards are heavy and brittle and need to be handled with utmost care. Cutting plasterboard is as easy as scoring on one side of the board and snapping off any excess.
Drywall can be applied to walls and ceilings with special nails or screws that are specific to drywall. They penetrate through the drywall without shattering it, but fixing it to the wall firmly. The screws and nails go in just past the surface, and the screws and seams are later covered with plaster products, and after it dries it is smoothed and sanded down.
