A sample answer to question 1

What does a typical day as a plasterer involve?

A typical day starts early. I check the work plan, load materials and arrive on site, then check the substrates and the conditions, including suction, temperature and access. I protect floors, windows and fittings, and set up scaffolding or a hop-up if needed. Then I mix material, such as multi-finish or bonding coat, to the right consistency, and apply it in layers, using a hawk and trowel, and straighten with a feather edge or darby. There is timing in everything, because plaster has a window in which you must trowel and polish it before it sets. I may also fit beads and stops, or do patching and repairs. At the end of the day, I clean tools thoroughly and tidy up, leaving the site safe. It is physical, skilled work that depends on speed and consistency.

Common mistake to avoid: Ignoring preparation; Skipping the clean-up
