Five free practice questions on safety, tools, access and job planning: block A of the Red Seal 404C Painter and Decorator exam, about 20 of its 130 questions. They are in the exam's format: four options, one correct answer. Answer each one before opening the explanation. No account, no email.
01The questions
-
In a new condominium, a drywall crew will be sanding compound in the next suite all week. Why does the painter hold the finish coat in this suite until they are done?
- Sanding dust would settle into the wet finish.
- Fresh paint fumes would soften their compound.
- Compound dust would change the colour of the paint.
- Their sanding vibration would crack the fresh film.
Show the answer
A. Correct. Fine compound dust drifts through doorways and openings and lands in a wet or tacky film, leaving a rough, specked finish that has to be sanded and recoated. Dusty work by other trades is coordinated to finish before the final coats.
Why not the others
B. Paint vapour does not soften set drywall compound. The concern runs the other way: their dust landing in the wet finish.
C. The dust shows as specks and roughness in the film, not as a colour change. The reason is contamination of the wet surface.
D. Sanding in the next suite does not shake the walls enough to crack paint. The concern is dust landing in the wet film.

A swing stage will be rigged down a building face where the building's overhead electrical service line passes the drop closer than the minimum distance the provincial regulation sets for its voltage. What is done before rigging?
- Have the utility shut off or move the line.
- Keep the wire ropes taut so they cannot swing in.
- Use synthetic fibre ropes instead of wire ropes.
- Rig it, with a worker posted to watch the line.
Show the answer
A. Correct. Inside the minimum distance the wire ropes, the stage or a tool could touch or arc to the line. The line's owner is asked to shut it off, verified off by its own qualified worker, or to raise or move it, or the drop is relocated, before the stage goes up.
Why not the others
B. Taut ropes still move in wind and as the stage travels, and the clearance is already below the minimum. The line has to be shut off or moved first.
C. Fibre rope that is damp or dirty can conduct, and the stage, hoists and tools are still metal. Changing the rope does not replace isolating the line.
D. A watcher helps when work stays outside the minimum distance; it does not make work inside that distance acceptable. The line must be shut off or moved first.

A painter will roll a solvent-borne primer in a small office with one window and one door to the corridor, using an explosion-proof fan. How is the ventilation set up?
- Fan in the middle of the room to keep air moving.
- Window fan blowing air in, with the door kept shut.
- Doorway fan exhausting the room into the corridor.
- Window fan exhausting out, door open for air in.
Show the answer
D. Correct. Exhausting at the window carries the vapour outdoors, and air drawn in through the open door replaces it, so the room stays slightly negative to the corridor and the painter works in the incoming fresh air rather than downwind of the vapour.
Why not the others
A. Stirring the air mixes the vapour through the room without removing it. Ventilation has to carry vapour outdoors and bring fresh air in.
B. Blowing in with the door shut gives the air nowhere to go, so the vapour stays in the room and is pushed out through gaps toward the corridor. Exhaust to outdoors, with an open path for make-up air.
C. Exhausting into the corridor sends solvent vapour into the occupied building. The vapour has to go outdoors, through the window.

-
Fourteen rolls of a printed vinyl arrive for a hotel suite. Eleven carry one run (batch) number and three carry another. What does the installer do before cutting?
- Reverse every strip cut from the odd rolls to even out the shade.
- Keep the three odd rolls off any wall hung from the main run.
- Hang all fourteen in roll order; run numbers track shipping only.
- Mix the odd rolls evenly through the room to average the shade.
Show the answer
B. Correct. Each run number is one printing, and the colour can shift slightly from run to run. Strips from two runs hung side by side show the change at the seam, so the odd run goes on a separate wall (changing at a corner) or back to the supplier for matching rolls. Checking run numbers before cutting is part of inspecting the material.
Why not the others
A. Reversing strips evens out edge shading within one run of a non-matching covering; it does not correct a colour difference between print runs, and on a printed pattern it can break the match. Different runs stay off the same wall.
C. The run number identifies the printing batch, not the delivery. Colour can vary between runs, which is why rolls are checked and different runs are not hung side by side.
D. Spreading the odd run through the room puts a different shade beside the main run at several seams, so the change shows in more places, not fewer. Different runs are kept off the same wall.

Primer on the third-floor walls of an office fit-out is still tacky after a cold night, so the vinyl cannot go up tomorrow. Which text message to the site superintendent follows good practice for electronic messages?
- FYI primer issue on 3, vinyl delayed TBD, crew reassigned, call me ASAP when you get this.
- Heads up, there is a problem with the walls upstairs. I will explain it when I see you on site.
- Third floor walls are not ready yet. The data sheet says not to hang a covering over tacky primer.
- Third floor primer still tacky; vinyl moves to Thursday. Please confirm we start the fourth floor.
Show the answer
D. Correct. A work text is written in plain language the reader can act on without a call: where, what is wrong, the new date and the decision needed. It stays professional, avoids slang and shorthand, and leaves a written record of when the superintendent was told.
Why not the others
A. A string of shorthand (FYI, TBD, ASAP) with no clear date or plan leaves the reader guessing and forces a call. Plain language with the floor, the problem, the new date and the request is the professional form.
B. This flags a problem but gives no floor, cause or new date, so the superintendent cannot plan around it. A good message says where, what, when and what is needed.
C. It names the problem and the reason but not the new date or what the crew will do instead, so the superintendent still has to chase the plan. The revised date and the decision needed belong in it.

03What block A covers
The skills every painting job rests on: respirators and other PPE, a safe work environment and hazards such as silica dust and solvent vapour, maintaining brushes, rollers and spray equipment, rigging and hoisting, ladders, scaffolds and lifts, reading drawings, specifications, SDS and data sheets, planning around weather and occupants, protecting surroundings, handling materials, judging substrate, product and finish defects, and communicating with clients and mentoring apprentices.
The Red Seal Occupational Standard names this block “Performs common occupational skills”. It carries 15.4% of the exam, about 20 of the 130 questions, split across five tasks. The share column is each task's weight within the block, as the standard publishes it.
| Task and its sub-tasks | Share of block |
|---|---|

| Performs routine trade practices Uses documentation; Determines project requirements; Plans job; Protects surroundings; Handles materials | 31% |
| Performs quality control assessments Assesses substrate conditions and deficiencies; Assesses product conditions and deficiencies; Assesses quality of painted or coated surfaces and wall coverings | 14% |
| Uses communication and mentoring techniques Uses communication techniques; Uses mentoring techniques | 7% |
04What the questions turn on
A respirator is only as good as its seal and storage
A tight-fitting respirator is checked with a negative and a positive pressure seal check every time it goes on, and stored clean in a sealed bag with nothing pressing on it, so the facepiece keeps its shape and the cartridges stay clean.
Damaged airless hose is replaced, never repaired
An airless hose carries coating at very high pressure. Tape or a field-fitted coupling cannot hold it, and a burst can inject paint through the skin, so a cut or bulging hose comes out of service.
The latest revision and the data sheet govern
Finishes are painted to the current drawing revision, and superseded copies are pulled from the site set. Weather windows come from the product data sheet: temperature, wind and the rain-free time after application all have to be met.
Read the failure before you fix it
An alkyd gone soft and sticky on damp new block is saponification: alkali and moisture breaking down the binder. Naming the defect correctly tells you whether to scrape, change the system or fix the moisture first.
