There are two main types of wall finishes: drywall and plaster. Plaster has been used for centuries, while drywall is a more modern invention. Both have their own advantages and disadvantages.
Drywall is made of panels of gypsum board that are fastened to the studs of a frame with screws or nails. Drywall is much easier to install than plaster, and it can be finished in a shorter time frame. Drywall is also fire resistant and soundproof, making it a good choice for homes in high-traffic areas or areas prone to earthquakes.
Plaster is made of lime, sand, water, and gypsum. It is applied to the lath (a framework of wood or metal strips) in three coats. The first coat, known as the brown coat, bonds the plaster to the lath. The second coat, called the scratch coat, is sanded smooth. The third and final coat is the finish coat, which can be textured or smooth.
Plaster takes longer to install than drywall, but it is more durable. Plaster walls can last for centuries, while drywall will need to be replaced every few decades. Plaster is also better at hiding imperfections in the wall, such as cracks and holes.
So, which is better? It really depends on your needs. If you need a quick, easy, and inexpensive wall finish, drywall is the way to go. If you want a durable and long-lasting finish, plaster is the better choice.
