Painter and Decorator (404C) Red Seal Exam in Alberta

Certifying authority: Alberta Apprenticeship and Industry Training (AIT). Last checked 2026-09-10.

Certification is voluntary in Alberta

This trade is not on Alberta’s compulsory list, so you may work in it without a certificate. The Red Seal still travels across Canada as a recognised credential, and employers frequently ask for it — but in Alberta it is a qualification, not a licence.

Quick 3-Question Painter and Decorator (404C) Readiness Check

Click any option (A–D) below to grade yourself immediately and view the worked explanation:

Sample Question 1 of 3
A journeyperson painter is booked to spray a two-component polyurethane topcoat on equipment inside a closed maintenance garage in Sudbury. The SDS for the hardener lists hexamethylene diisocyanate, the bay has only general ventilation, and the crew has been fit-tested only on half-face cartridge respirators. Which respiratory protection should the painter use for this spraying?
A) A supplied-air respirator, with the painter trained and fit-tested on it
B) A half-face respirator with organic vapour cartridges and P100 prefilters
C) A full-face respirator with organic vapour cartridges changed each shift
D) A disposable N95 respirator, with an extra exhaust fan set in the doorway
Correct answer: A

Sprayed isocyanates are strong respiratory sensitizers with poor warning properties, and SDSs for these hardeners typically call for supplied air when spraying in an enclosed space. Cartridges give no reliable end-of-service warning, and an N95 stops particles only.

Sample Question 2 of 3
A painter in Guelph is finishing six new bare pine interior doors in a satin enamel. The doors have small chips and nail holes to fill. On the last job, every filled spot showed through the topcoat as a dull, flat patch, because the filler soaked up the enamel differently from the rest of the door. Which sequence avoids this problem?
A) Apply the enamel first, then fill any flaws that show and touch up the filled spots with a small brush, using the same enamel
B) Fill and sand the flaws, then apply the satin enamel straight over the bare wood and the filler, adding a third coat to even out the sheen
C) Prime the whole door, then fill and sand the flaws and apply the enamel over them at once, without priming the filled spots again
D) Fill and sand the flaws, then prime the whole door, so the filled spots are sealed before the enamel goes on, and spot-prime any refills
Correct answer: D

Filler is more porous than primed wood, so filled spots left unsealed absorb the enamel and show as flat patches, called flashing. Every filled spot must be primed before the topcoat, whether the filling is done before priming or after it.

Sample Question 3 of 3
A painter in Halifax lifts a corner of the old paper in a hallway with a putty knife and pulls it slowly at a low angle. The whole strip comes away dry in one piece, face and backing together, and leaves the primed drywall clean and undamaged behind it. What type of wallcovering is this?
A) Non-strippable
B) Peelable
C) Strippable
D) Pre-pasted
Correct answer: C

A strippable wallcovering comes off dry, face and backing together, leaving little or no residue. A peelable one leaves its backing on the wall, and a non-strippable one must be scored and soaked. Pre-pasted describes the adhesive, not how it comes off.
