Plastering walls was often impossible in cooler weather, and the job required significant skill to get quality results. The plaster was applied wet, and would take a significant amount of time to dry. The wood strips, or lath, served as a substrate onto which skilled tradespeople would apply plaster. This usually involved nailing up many thin strips of wood to the wooden structure of a house, to make up walls and ceilings.

Significant skill is required to apply a smooth, consistent plaster finish. Before Drywall A lath and plaster wall, with wallpaper applied over the top. Today, we’ll look at how it came about, and why it went on to dominate the world of construction. However, drywall has not been around forever, and actually took many years to establish itself as a popular building material. Many of us barely think about it until we have to repair a hole smashed in it. Drywall is common and ubiquitous in commercial and residential buildings today.
