Plasterer
What you'd actually do
The work is preparing surfaces, mixing plaster, applying it evenly by hand and trowel, and smoothing it to a perfect finish, as well as rendering outside walls. It takes skill, a good eye, speed and a steady hand, since plaster sets fast and a smooth result is hard to get right - this is a craft that takes time to master.
You may work for a firm or be self-employed, travelling between jobs, doing physical work that is hard on the arms and back and often messy, with busier spells when building work picks up. Pay grows well with skill and reputation, and self-employed plasterers carry the ups and downs of finding work.
Most people learn through a plastering apprenticeship or college course, then build speed and skill on site. A CSCS card is usually needed for building sites, a driving licence helps, and a reputation for tidy, fast work brings repeat business.
