Plastering looks effortless when a professional does it, which is exactly why it catches beginners out. The good news is that most first-timer problems come from the same handful of mistakes, and every one of them can be avoided.
Poor preparation
A great finish starts before the plaster is mixed. Dusty, flaky or uneven surfaces will cause plaster to fail. Walls need to be clean and sound, with the right bonding or primer applied for the surface you are working on.
Wrong mix
Plaster that is too wet slumps and cracks. Plaster that is too stiff drags and will not spread. Learning what the right consistency looks and feels like is one of the hardest things to pick up from reading alone.
Working too slowly
Plaster starts to go off whether you are ready or not. Beginners often fiddle with an area for too long. Confident, deliberate strokes in the right order make a far better surface.
Overworking the surface
Going back over plaster that has started to set tears the finish. Knowing when to leave it alone, and when to trowel it up, is about timing and practice.
Weak trowel technique
Angle, pressure and the way you load the hawk all affect the result. Small corrections made by an instructor standing next to you make a big difference very quickly.
Rushing the drying
Plaster needs time to dry properly before you decorate. Painting too early can lead to peeling, patchy colour and damp problems.
