Gypsom
Material used on walls. Also known as sheetrock or drywall. (There, raw gypsum is mixed with several additives, including starch, paper pulp and an emulsifier (or thickening agent), then blended with water to form a thick paste.
Mud
Mud is slang for a joint compound that makes a finish, and closes the seams that occur when drywall sheets are hung side by side.
Finishing
The final coat is called the skim coat. A 10-or 12-inch knife should be used to apply a third coat of mud. Take your time on this coat to spread the mud thinly away from the seams to provide a smooth, level surface.
History of Drywall
The material was first sold in the form of small, fireproof tiles, but within a few years, it was sold in multi-layer gypsum and paper sheets. In less then a decade, it took on the form we know, consisting of a single layer of compressed gypsum sandwiched between two sheets of heavy paper.
Where did the name Drywall come from?
The name "drywall" refers to the fact that walls made of the material are installed without the use of water.
repair
This damage is simple to repair, and simply involves filling any holes, then covering them with mud and sanding them so they are smooth and flush with the rest of the wall. For larger holes, cut out a piece of drywall that will roughly fill the hole, then fill the rest of the space with mud.
