It was later made into larger sheets and nailed to wooden studs on walls. It was then covered with plaster and special tape to hide the seams. This process is known as “taping and bedding” or “mudding.” In the United States, drywall became a replacement for plaster. The product was also painted.

Drywall is made from gypsum, which is a soft white mineral that is turned into a plaster powder by chemical reactions. It is then applied to walls and ceilings as a solid layer over wooden studs drywall installation. It is often used in construction because of its strength and durability, but also because it is inexpensive and easy to work with.

Gypsum is a sedimentary rock that is similar to sand. It is white and sometimes pink. It is mined and then transported to manufacturing plants where it is mixed with additives and a thickening agent. The resulting mixture is then applied to Manila paper and laid onto the wall. After that, the drywall paste is heated to about 500 degrees. During the process, it is mixed with other materials, including plasticizer, fiber, and glass wool.
