Old houses built during the 1700s through until the 1940s commonly utilized a unique wall construction method known as plaster and lath. This method involved nailing thin wooden strips made from timber (lath) to the studs on the wall and then layering several coats of plaster on top of the lath to create a smooth wall surface. This approach had gained immense popularity because of several reasons. The plaster and lath method was affordable, faster to install, and allowed for better sound insulation as compared to other wall construction methods. Additionally, it also allowed builders to create stunning plaster designs and ornamentation on the walls.
