The crew crafted the job around the cornices, building plaster walls and reviving the ceiling without building out beyond the cornice profile.Drilling into plaster walls can seem intimidating, but with the right tools and knowledge, it can be a relatively simple task. Where the ceiling had been punched open for ceiling supports, patching was done with wire mesh and plaster before a skim coat was applied to the entire ceiling. In areas where the brick had deteriorated, wire lath was used to create a sound surface and a level wall. In the Manhattan Brownstone project, a variety of methods were employed, including plastering directly over the existing brick walls that were first treated with a blue bonding agent. Sometimes they can use the brick surface that remains, sometimes they must affix wire lath to the brick to serve as a support for keying the new plaster. “Our crew makes a determination on an individual basis,” Annino says. The plaster crew must first assess the existing walls, masonry, or ceilings that need to be plastered. The quality of any plaster job and the degree of adhesion depends, in large part, on the integrity of the surface on which it’s applied. “Each plaster job is unique,” Annino says. Master plasterers work with a spray bottle to keep the plaster wet as they smooth it to a perfect finish. At this point it is ready to be mixed into putty.
Many firms now work with gypsum since it eliminates the need for added fiber and has a much quicker set up and drying time.
The lime is typically derived from limestone or ground oyster shells. These coats form the base of the wall and are mixed of lime or gypsum, aggregate, fiber, and water. The three-coat plaster system begins with two coarse or rough coats.
