What You'll Learn

Key competencies developed through this program

Auto-populatedfrom NSX Competency Framework

Mastery: developing (Level 2)(based on Apprenticeship)

Standard terrazzo mix formulas — measure and batch with reduced oversight, adjusting ingredient quantities using scales and graduated containers for routine residential and light-commercial installations.
Power grinder and surfacing machine — operate independently to grind and polish flat terrazzo surfaces, maintaining consistent speed and pressure to meet specified finish tolerances.
Metal division strips — cut, fit, and press into terrazzo bases with limited supervision to create accurate joints, color boundaries, and crack-prevention lines on mid-complexity floor designs.
Marble chip panels — blend chip mixtures to specification, place evenly into framed panels, and embed thoroughly with a roller to achieve uniform surface texture on standard commercial projects.
Mixing and grouting procedures — modify routine sequences based on material type or substrate condition, such as switching from wet-mix to dry-mix methods on varied interior surfaces.
Hand and power trowels and screeds — use to spread, level, and finish terrazzo bases to grade across straightforward floor sections with minimal direction from a lead worker.
Portable hand grinder — apply to curved surfaces and confined areas such as stair treads and cabinet edges to achieve consistent finish where machine access is restricted.
Post-polish cleaning sequence — wash terrazzo surfaces with appropriate cleaner, then apply sealer and curing agent per manufacturer's specifications, working independently on standard interior floors.
Quality control checks — inspect finished terrazzo surfaces for voids, surface defects, and pattern alignment, recording observations and flagging non-conformances to a supervisor.
Coordination with other trades on the job site — schedule grinding and finishing tasks around concrete curing timelines and adjacent construction activities to maintain project progress.
