Apprenticeship is a method of gaining the expertise needed to become a skilled tradesperson. This is done through a combination of on-the-job experience and classroom training.

Most apprenticeship programs are 3-4 periods in length, with an average of 8 weeks for each training period. In addition, there are specific allotments of on-the-job training hours associated with each period, so most apprentices complete 1 period per calendar year.

You want to be a lather. You want to install a wide variety of wall and ceiling systems and become an expert on bringing buildings under construction to their completed state, including completing exterior finishes and installing doors, windows and insulation.

But you need to learn more, like how to apply various base materials for stucco finishes, including Styrofoam, stucco wire or metal lath, or how to erect demountable partitions and suspended ceilings for commercial office spaces.

At NAIT, we’re here to teach you everything you need to know.

Here are some of the other subjects covered in the Lather (Interior Systems Mechanic) apprenticeship program at NAIT:

  • reading blueprints and shop drawings
  • installing metal framing for walls, partitions, ceilings and ornamental detail
  • working with other trades to accommodate heating, plumbing, electrical and millwork
  • drywalling in commercial, residential and industrial projects

Hands-on, industry-relevant skills

If you are a capable problem solver and creative thinker who enjoys working at a variety of tasks and values learning skills that require a high degree of accuracy, then you will enjoy working as a lather.

Lathers work indoors or outdoors, most often for a construction company building large commercial complexes or residential homes. You will be required to work on aerial platforms, scaffolding and ladders to complete some jobs.

To be successful as a lather, you must have:

  • good hand-eye coordination
  • physical fitness
  • the ability to lift in excess of 25 kgs
  • a careful attention to detail
  • the ability to work well with others and independently

Training at NAIT

The Lather (Interior Systems Mechanic) apprenticeship term is:

  • 3 years (three 12-month periods)
  • minimum of 1560 hours on-the-job training each year
  • 8 weeks of technical training each year
  • See all period descriptions

Enter the workforce with confidence

As a lather, you will be employed by contractors in the construction industry. All lathers have the opportunity to become certified journeypersons, supervisors, project managers or estimators. You can also work as a self-employed lather.

Experienced lathers may become specialists at working with a specific type of lath.
