At left you can see the ears or plaster ears formed by the plaster base coat, or brown coat the first plaster layer applied onto the wood lath of this antique New York home. Youll also notice that especially in older structures whose interior partition walls often used minimal and irregularly spaced framing for interior walls and ceilings, the plasterer sometimes tacked up an extra wood scrap the diagonal log in our photo at left to improve support for plaster lath, or to provide a nailing surface to secure the ends of wood lath that otherwise did not reach a vertical wall stud.

When applied over wood lath or later, metal lath, the first coat of plaster, the brown coat or scratch coat, is pushed through openings in the lath so that when it hardens it is mechanically secured to the building wall or ceiling. Below is a photo of the base coat of plaster viewed from the other side of a hand split lath wall in a pre 1. I restored. The base coat was very coarse and was referred to as a scratch coat or brown coat. Sometimes in attics and basements just the brown coat or scratch plaster coat was applied, which is why I was able to take the photo shown just below. The gouges or scratches in the brown coat were made by the plasterer using a notched tool or saw tooth edged tool to improve the adhesion of the next coat. The first two plaster coats would each be about 38 thick while the final coat was quite thin, just 18 in thickness. Our plaster scratch coat or brown coat photo below shows how this surface was sometimes scarified to provide better adhesion of the top coats of plaster. However often the brown coat was simply applied roughly without gouging, as we show in this extra plaster rough coat photo Image file. The second coat of plaster in a three coat system was used to bring the surface of the finished wall forward and add thickness before applying the thinner, smoother finish coat. Our photo at below left shows a common practice in roughly finished attics just a thin skim coat of plaster was applied directly to the wood lath you can see the wood lath telegraphing through the plaster coating. Very often plaster cracking follows the lines of these lath strips.
