Why should I choose plaster for my interior walls?
When most people think of remodeling or building a home, the first thing that comes to mind is kitchen and bathroom fixtures, adding square footage and windows and doors. Very little thought goes to the interior walls. People don’t think of their interior walls unless there is a problem. Though they do provide separation and privacy as well as act as sound barriers, fire resistance and insulation.
The two most common materials for interior walls are drywall and plaster. Plaster has actually been used since ancient times, commonly made of lime, sand, water and animal hair. Newer plaster is done with gypsum as it has faster drying time which was crucial to make construction time faster. As technology advanced drywall became more durable and readily available.
The advantages to plastering is the walls are created through a 3 step process. A lath is laid down and gives the gooey plaster the texture to hang onto. The first coat is laid applied, scratched and left to dry. It is important to have the right consistency for both this and the final layer to have a perfect texture and density. Because of the number of layers and lathing plaster walls are usually thicker than drywall which results in a better sound barrier as well as more insulated weather and air barrier. With the lathing, plastering can provide a more rigid wall which helps the walls ability to withstand breaking and buckling. The walls also have high water content due to the gypsum which has a much higher fire resistance than drywall.
