Hello!
A question for the plastering experts:
We are currently having a garage built by a construction company. So far, it has been a series of setbacks and problems, and by now we are confused about what we are being told.
Specifically, the openings for the garage doors were built about 8cm (3 inches) too high. The plasterer glued Styrodur (rigid foam) pieces in the openings and applied a lime-cement plaster as a base coat on top. The result looked more like arches than straight lintels. They tried to fix it with the base coat, but it is still uneven and crooked. Now they want to add another layer of plaster to finally make it level.
Is this a sensible, solid, and acceptable method of repair, or will the plaster start to crumble after a few years because applying several layers of plaster over a few centimeters is not ideal, and then the construction company will no longer be interested?
Second question:
The garage was built directly onto the existing house. The house has a pigmented silicone-based roughcast (rough render). The garage is supposed to have a pigmented mineral render. Unfortunately, the plasterers managed to smear their lime-cement base coat onto the adjacent walls of the house. The construction company now wants to apply a strip of the garage plaster over the house wall to cover up the mess. Aside from the fact that we do not want this at all: Is this approach durable, considering that two different types of plaster are being applied on top of each other? Are there any other effective options to solve the problem?
