Concrete Finishers place, finish, protect and repair concrete surfaces. They work on a variety of vertical and horizontal surfaces such as concrete floors, walls, sidewalks, stairs, driveways, and overlays, and they work on many types of structures such as buildings, dams, bridges and tunnels. They texture, chip, grind and cure finished concrete work and repair and restore damaged concrete. They apply architectural finishes to concrete surfaces, and they install expansion and contraction joints and fixtures such as anchor bolts, steel plates and other embedments. They also apply membranes and other waterproofing products to concrete.
Concrete Finishers must possess a sound knowledge of the properties of various types of concrete mixes and how proportions, additives and curing affect concrete strength and durability. They should have a basic knowledge of constructing formwork, preparing subgrades and installing reinforcement.
