Red Seal Program

The Red Seal Concrete Finisher exam is the Interprovincial (IP) certification for cement and concrete finishers in Canada, administered through the Red Seal Program. It is a multiple-choice exam of approximately 100 four-option questions with a 70% passing score, and exam/challenge fees vary by province or territory (roughly $100-170 CAD). The exam is built from the Red Seal Occupational Standard and tests safety and common skills, formwork and site preparation, placing and consolidating concrete, finishing flatwork, decorative and architectural finishes, and curing, repair, and restoration. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

Sample Red Seal Concrete Finisher Practice Questions

Try these sample questions to test your Red Seal Concrete Finisher exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Wet (plastic) concrete is highly alkaline. Which personal protective equipment is most important for a finisher kneeling and working on a freshly placed slab for an extended period?
A.Hearing protection only
B.Waterproof gloves, rubber boots, and waterproof kneepads
C.A dust mask and safety glasses only
D.A high-visibility vest only
Explanation: Fresh concrete contains calcium hydroxide and is caustic (pH around 12-13); prolonged skin contact causes chemical burns. Waterproof gloves, rubber boots, and waterproof kneepads keep the alkaline slurry off the skin during finishing.
2Crystalline silica dust generated when grinding or cutting cured concrete is a serious health hazard primarily because it can cause which disease?
A.Silicosis
B.Tetanus
C.Dermatitis
D.Heat stroke
Explanation: Respirable crystalline silica from grinding, cutting, or sweeping cured concrete lodges in the lungs and causes silicosis, an irreversible fibrotic lung disease. Wet-cutting, local exhaust ventilation, and an appropriate respirator control the exposure.
3Before any work begins, what document identifies hazards of a task and the controls used to mitigate them on a construction site?
A.A purchase order
B.A Job Hazard Analysis (JHA) or Field Level Hazard Assessment (FLHA)
C.The concrete delivery ticket
D.A bill of materials
Explanation: A Job Hazard Analysis (also called a Field Level Hazard Assessment) breaks a task into steps, identifies the hazards of each step, and lists controls. It is completed before work starts and reviewed with the crew.
4A Safety Data Sheet (SDS) for a liquid curing compound must be available on site. Which section of the SDS lists the required personal protective equipment and exposure controls?
A.Section 1 - Identification
B.Section 8 - Exposure controls/personal protection
C.Section 14 - Transport information
D.Section 16 - Other information
Explanation: Under the GHS/WHMIS 2015 16-section format, Section 8 covers exposure limits, engineering controls, and the PPE needed to handle the product safely.
5When manually lifting a heavy bag of cement, which technique most reduces the risk of back injury?
A.Bend at the waist and twist to set the load down
B.Keep the load close to the body, bend the knees, and lift with the legs
C.Lift quickly with straight legs to minimize strain time
D.Hold the load at arm's length to keep it away from the body
Explanation: Proper manual handling keeps the load close to the body's centre of gravity, uses the large leg muscles by bending the knees, and avoids twisting the spine under load, all of which reduce compressive and shear forces on the lower back.
6A finisher must enter a deep, narrow trench to place and finish a footing. Before entering, the trench wall must be protected against collapse. Which is an acceptable method?
A.Sloping, benching, or installing a trench shield/shoring system
B.Posting a warning sign at the top of the trench
C.Working quickly so exposure time is short
D.Spraying water on the walls to harden them
Explanation: Excavation cave-in protection requires engineering controls such as sloping the walls to a safe angle, benching, or installing shoring/trench boxes per provincial OHS regulations. These prevent the wall from collapsing on a worker.
7Power trowels (ride-on or walk-behind) used to finish large slabs may be powered by gasoline or propane engines. What is the main reason propane is often preferred for interior power-floating work?
A.Propane engines are quieter
B.Propane produces lower carbon monoxide and exhaust emissions in enclosed spaces
C.Propane gives more horsepower
D.Propane trowels spin faster
Explanation: Propane (LPG) engines burn cleaner than gasoline, producing significantly less carbon monoxide, which is critical when power-floating indoors where CO can accumulate to lethal levels. Adequate ventilation and CO monitoring are still required.
8When a concrete pump and boom are set up near overhead power lines, what is the primary control to prevent electrocution?
A.Maintain the regulated minimum approach distance from the energized lines
B.Wear rubber gloves while operating the boom
C.Spray the boom with water to ground it
D.Operate the boom only at night
Explanation: Provincial OHS regulations require a minimum approach (limit-of-approach) distance between equipment and energized overhead lines, based on voltage. Keeping the boom and any conductive tools outside that distance prevents arcing and electrocution.
9Which fire extinguisher class is appropriate for a fuel (gasoline) fire on a job site, such as at a power-trowel refueling area?
A.Class A (ordinary combustibles)
B.Class B (flammable liquids)
C.Class C (energized electrical)
D.Class D (combustible metals)
Explanation: Class B extinguishers are rated for flammable and combustible liquids such as gasoline, diesel, and propane. Many job-site extinguishers are multi-class ABC, which also covers Class B fires.
10On a construction drawing, a dimension noted as '150' on a metric plan most commonly refers to what for a typical residential garage or basement slab thickness?
A.150 metres
B.150 millimetres
C.150 centimetres
D.150 inches
Explanation: Canadian construction drawings use SI units, with linear dimensions on building drawings given in millimetres unless otherwise noted. A 150 mm (about 6 in) slab is a common residential thickness.
