Gypsum, also known as calcium sulfate, is a mineral that is found in many places around the world. It is a common material used in building and construction, and has many different uses. In some cases, it is used to help hold up the mortar in the wall and to make the flooring more durable. In other cases, it is used to fill any small spaces between the boards in a build-out project.
The main thing that makes gypsum so great for these purposes is that it contains water of crystallization. This means that when it is used in this way, it can hold up to a lot of wear and tear. In addition, it is very strong and does not break easily.
