Scratch Coat

November 23, 2015  •  10 Comments


I haven't posted photos of the progress on the Imperial Building recently because there hadn't been a lot of visual changes while they finished tacking tarpaper and chickenwire in the side of the building in preparation for plaster. They had the first coat of plaster, called the "scratch coat", on the east side of the building last Friday. They call it the scratch coat because after the plaster is applied over the chickenwire, which helps hold the plaster on the wall, the plasterer scratches horizontal ribs in the wet plaster. When the plaster dries, the scratches create a hard ribbed surface for the second coat of plaster to cling to. The second coat of plaster is smooth and called the "brown coat" (in older buildings the brown coat often had a brown or sandy color). Together the two coats of plaster form the "scratch and brown" base coat for the final stucco finish.

So that how the plastering is done! I always enjoying reading about how things are done or made. Nice photos of the progress.

Hi Couriers. I think the final color will be a light yellow or tan.
So far it looks rather drab - suspect the final stucco coat might be a little more exciting!

Thanks, Christine! If your house is stuccoed, most likely. There are some one-coat stuccos out there, but usually the scratch and brown coat under the stucco is more normal (out here anyway).
