Photo #1 is of a great room in a home. It is an example of a situation that created a profitable opportunity. This type of complaint is unfortunately becoming more common as time goes by. It involves the board seams showing through the plaster. This is a complaint that often happens in drywall finishing projects, and personally I feel it should never happen with plastering, but it does. Part of the problem here is created by hanging the board badly. Large gaps are left between the boards and when plaster is applied over these, often a bulge is created. However, this was not the case in this house. The problem here was that the crew simply tried to save money.
They used razor trowels (thin finishing trowels) and used a ton of pressure when doing the basecoat. The material was paper-thin and the pressure created bulging of the seams. A little more basecoat would have gone a long way and would have saved the plasterer thousands of dollars and a court date. That's because I was called in to fix these seams.
