To ensure that the plaster is applied evenly and smoothly, it is important to use a trowel that is the correct size for the job. The trowel should also be held at a 45-degree angle to the wall. The plaster should be applied in a thin, even layer, and it should be smoothed using a float as soon as it has been applied.
