The short answer

Judge finished plastering in raking light, low, angled light shows what flat light hides.
Preparation determines the result. Skimming over unsound surfaces will fail.
Establish whether it is a skim over existing or a full re-plaster; the difference is substantial.
Drying times are real. Decorating too early causes problems.
Ask who covers floors and clears up, plastering is a messy trade and this is often excluded.

What makes hiring a plasterer different

Plastering is judged almost entirely on surface flatness, which is invisible under normal lighting and obvious under a lamp held close to the wall.

That gap is the trade's characteristic dispute. A homeowner accepts the work on the day, then puts up a light fitting three weeks later and sees every ripple.

It is also a trade where preparation is most of the job and is easy to skip. Skimming over blown plaster, loose paint or unsuitable substrate produces work that fails regardless of how well the finish coat is applied.

Skim or full re-plaster

A skim is a thin finish coat over an existing sound surface. Cheap and quick, but only appropriate where what is underneath is solid.

A full re-plaster removes the old and builds up again. More expensive and necessary where the existing surface is blown, damp-damaged or lath and plaster in poor condition.

In older properties this distinction matters considerably, and a quote for a skim on a wall that needs stripping is not a competitive price, it is a different job.

Drying and what comes after

Fresh plaster needs to dry before decorating, and the time depends on thickness, ventilation and season. Painting too early traps moisture and causes flaking.

Ask how long they recommend and plan the decorating around it. Also expect some hairline cracking as it dries; that is normal and filled at decoration.

Deposits and payment stages

Materials are cheap relative to labour, so no deposit should be needed on ordinary work.

Inspect in raking light before the final payment. Take a lamp, hold it flat to the wall, and look along the surface. Do it while the plasterer is still there.
