An interior plasterer installs plaster sheets and decorative mouldings or fittings to the inside of buildings, and stops (fills in) plaster-board holes and joints in walls or ceilings.
Tasks and Duties:
- erects the scaffolding
- installs ready-made sheets and plaster fixtures
- fixes the plaster
- applies and smooths the coats of plaster
- fills in holes and cracks in plasterglass and gib board.
- Some interior plasterers may specialise in making plaster, and combine this role with installation.
Interior plasterers need to have practical skills (such as being able to mix plaster and erect scaffolding), problem-solving skills, and organisational ability, as plastering is a step-by-step process. They also need to have skill in making calculations, an eye for detail, good oral communication skills and the ability to follow instructions.
Interior plasterers need to know about plastering materials and how to achieve different levels of finish for a surface. They need to know how to interpret plans and must have some knowledge of various building styles, including past and present decorating styles.
Interior plasterers should be careful, reliable, creative and artistic. They also need to be able to work well under pressure, and have a high standard of finishing work.
Interior plasterers need to be fit, healthy and strong, as the work they do is very physical. They also need to have good co-ordination, good eyesight (with or without glasses) and steady hands.
NCEA Level 1 in English, maths, science and graphics is preferred.
A current drivers license is generally required.
Previous experience in the building industry, work using hand tools or work as a carpenter may be useful for interior plasterers.
Training on the job
Apprenticeships in interior plastering are available, which involve undertaking training on the job. Interior plasterers can complete a range of national certificates through the Building and Construction Industry Training Organisation.
Interior plasterers work inside, in buildings that are under construction or being altered or renovated. Interior plasterers usually work indoors.
Salaries range between $28,000 and $40,000 per annum, with more for overtime. Self-employed plasterers may earn more than this.
