Click any option (A–D) below to test yourself & reveal the worked explanation.

Question 1 of 10

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.

Question 2 of 10

A painting contractor in Brampton is ordering tape for a drywall job with 850 m of flat joints and 420 m of inside corners. Flat joints get self-adhesive mesh in 90 m rolls, inside corners get paper tape in 150 m rolls, and the estimator adds 10% waste to both lengths. How many rolls of each should be ordered?

A) 11 mesh, 3 paper

B) 10 mesh, 3 paper

C) 10 mesh, 4 paper

D) 11 mesh, 4 paper

Correct answer: D

Mesh: 850 x 1.10 = 935 m; 935 / 90 = 10.4, rounded up to 11 rolls. Paper: 420 x 1.10 = 462 m; 462 / 150 = 3.08, rounded up to 4 rolls. Rolls are rounded up, since 10 or 3 rolls would leave the job short.

Question 3 of 10

A painter in Laval is preparing new cast-in-place concrete walls in a parking garage for a coating. Water sprinkled on the walls beads up in patches, and the form crew mentions that the forms were oiled and a curing compound was sprayed on afterward. What must be done before priming?

A) Acid-etch every wall, since acid removes any release agent completely

B) Nothing, since new concrete is clean and ready for coating as it is

C) Remove the form oil and curing compound by the method the maker gives

D) Dust the walls off only, since the oils burn off as the concrete cures

Correct answer: C

Form oils and curing compounds are made to stop things sticking, and they stop coatings sticking too. They are removed by the method the coating maker recommends, often detergent cleaning or light abrasive blasting, and the surface is retested before priming.

Question 4 of 10

In a poorly ventilated bathroom of a Vancouver rental suite, black, blotchy spots keep coming back on the ceiling above the shower, even after the tenant wiped them last month. The exhaust fan is not working, and the landlord wants the ceiling repainted. What is the cause, and what is the right treatment?

A) Efflorescence; brush it off and wash with water, then repaint

B) Mildew; kill it with a mildew wash, rinse, and fix the fan

C) Candle soot; wipe with detergent, then repaint with flat latex

D) Water stain; spot prime with stain blocker and paint over it

Correct answer: B

Damp air and poor ventilation feed mildew. It is killed and cleaned off with a mildew wash, rinsed and dried, and the exhaust fan is fixed so it does not return; a mildew-resistant bathroom paint helps. Painting over live mildew lets it grow through.

Question 5 of 10

A painting contractor in Brampton is setting up a shop storeroom for solvent-borne alkyds, acrylic latex, a caustic stripper, a muriatic acid etch and a pail of pool chlorine used in mildew wash. To save space, the owner plans to put everything on one shelving unit in the order the products are used. Which storage principle matters most here?

A) Keep incompatibles apart: acids, bases, oxidizers and flammables

B) Shelve every product in alphabetical order, so it matches the SDS binder

C) Keep all of the products together by the door, so spills are seen quickly

D) Store every product in a heated room, so that none of them can freeze

Correct answer: A

SDS sections 7 and 10 list incompatible materials. Acid mixed with chlorine releases chlorine gas, an oxidizer next to solvents can start or feed a fire, and acids and caustics react violently, so the groups are kept apart with spill containment.

Question 6 of 10

A crew will spray the exterior of a five-storey building in Vancouver next to a busy sidewalk and a parking lot. The forecast is for winds of 15 to 20 km/h, gusting higher in the afternoon, and the owner is worried about overspray on cars and pedestrians. Which plan best controls the overspray?

A) Rope off part of the sidewalk, spray only when nobody happens to be passing, and leave the cars as they are in the parking lot

B) Hang light plastic sheets loosely from the scaffold rails, spray at full pressure to finish fast, and wash any cars that get spotted later

C) Lower the spray pressure, rely on the wind to carry the fine overspray away, and spray each section while the sidewalk is quiet

D) Enclose the work face with secured, overlapped sheeting, protect the sidewalk and cars, and stop spraying if the wind passes the plan's limit

Correct answer: D

Wind carries overspray far beyond the building, so the work face is fully enclosed with secured sheeting, people and vehicles nearby are protected, and spraying stops when the wind exceeds what the plan allows; rolling and brushing are the fallback.

Question 7 of 10

Marbling the columns of a Montreal theatre lobby, a decorative painter has laid in veins of dark glaze with a fine liner brush. The veins look hard-edged and painted on, and the restoration architect wants soft, cloudy edges like real marble. The glaze is still wet. What should the painter do to soften the veins?

A) Pounce the veins hard with a stiff stencil brush to break them up

B) Whisk lightly across the wet veins with a soft badger blender brush

C) Wipe each vein with a rag dampened in solvent to thin out the glaze

D) Let the veins dry fully, then sand them back with a fine abrasive

Correct answer: B

A badger blender, whisked lightly over wet glaze, feathers hard edges into soft, cloudy veins without brush marks. A stiff brush leaves texture, solvent rags lift the glaze unevenly, and sanding dry glaze cuts through it.

Question 8 of 10

A finisher in Winnipeg is mixing shellac from flakes for a sealer coat on an antique dresser and writes '2-pound cut' on the jar. The apprentice asks what the label means and how it relates to the strength of the solution. What does a 2-pound cut describe?

A) A shellac that is dry enough to recoat within about two hours

B) A shellac thinned with two parts of water to one part shellac

C) 2 lb of shellac flakes dissolved in one US gallon of denatured alcohol

D) 2 lb of mixed shellac needed for each room that will be sealed

Correct answer: C

The cut is the weight of shellac flakes dissolved in a gallon of denatured alcohol. A 2-lb cut is a common general strength, and lighter cuts are used for sealing and French polishing.

Question 9 of 10

Light standards for a new parking lot in Winnipeg are specified as hot-dip galvanized and then painted with an epoxy and polyurethane system. The owner's project manager asks why both are needed, since galvanizing alone already protects steel well. What is the main benefit of this duplex system?

A) The epoxy seals in any white rust, so the zinc needs no preparation

B) Galvanized steel rusts in its first winter unless it is painted at once

C) The zinc acts only as a primer, so its thickness does not matter at all

D) The paint shields the zinc, and the zinc protects the steel at any damage

Correct answer: D

In a duplex system the paint slows the consumption of the zinc, and the zinc protects the steel wherever the paint is damaged, so together they last longer than either alone. The galvanized surface is still prepared, often by sweep blasting, as the paint maker directs.

Question 10 of 10

A blaster in Trois-Rivières notices that production on a bridge bearing job has dropped over the week, the compressor now runs flat out, and the nozzle pressure reads lower than it did on Monday. A nozzle orifice gauge shows that the tungsten carbide nozzle bore has worn well oversize. What should the blaster do?

A) Keep using it, since a larger bore always cleans more steel per hour

B) Raise the compressor output, since a worn nozzle blasts a faster pattern

C) Replace the nozzle, as a worn bore uses more air and drops pressure

D) Add more abrasive at the metering valve to make up for the lost pressure

Correct answer: C

A worn bore passes more air than the compressor can supply, so nozzle pressure and cleaning rate drop and abrasive use rises. Nozzles are checked with an orifice gauge and replaced when worn past the maker's limit; more abrasive only slows each particle down.

404C Painter and Decorator Coverage, WFT/DFT & Coating Systems Reference

Essential formulas, Canadian code standards, and critical numerical thresholds tested on the Interprovincial Red Seal Painter and Decorator (404C) exam:

Coating / Surface Topic	Formula or Industry Standard	Exam Application & Key Value
Dry Film Thickness (DFT) vs. Wet Film (WFT)	DFT = WFT × (% Volume Solids ÷ 100) \| WFT = DFT ÷ (% Solids ÷ 100)	Adding thinner reduces effective volume solids: WFT = DFT × (1 + Thinner %) ÷ % Solids
Theoretical Paint Coverage	1 US gal at 100% solids covers 1,604 ft² at 1.0 mil WFT	Material Needed = Total Surface Area ÷ Practical Spread Rate (subtract openings > 100 ft²)
Airless Spray Tip Code (e.g., 517)	Fan Width (at 12 in.) = First Digit × 2 \| Orifice = Last Two Digits (thousandths)	Tip 517 = 10 in. fan width and 0.017 in. orifice; replace tip when fan shrinks by 25%
Concrete & Masonry Cure & pH	Cure new concrete ≥ 28 days; pH < 9–10; moisture < 12%	High alkalinity saponifies oil/alkyd binders; use alkali-resistant acrylic primer
SSPC / NACE Steel Blast Profiles	SP-5 (NACE 1) = White Metal \| SP-10 (NACE 2) = Near-White (95%)	SP-6 (NACE 3) = Commercial Blast (67%); SP-7 = Brush-Off Blast
Wallpaper Roll Estimation	Usable Strips per Roll = Roll Length ÷ Pattern Repeat Length (round down)	Plumb line is always struck from the edge of the first strip minus 1/2 in. at corners

Worked examples: film thickness, coverage and mixing ratios on the Painter exam

On the 130-question exam, the three heaviest blocks are Prepares and applies residential, institutional and commercial paints, coatings and finishes (31 of 130 questions), Prepares surfaces (30 of 130 questions) and Prepares and applies industrial paints and coatings (29 of 130 questions). Wet-to-dry film thickness, net wall area and two-component mixing ratios are core trade math:

Worked example 1

An industrial epoxy coating has 60% volume solids. To achieve a specified dry film thickness (DFT) of 150 μm (6.0 mils), what wet film thickness (WFT) must be applied?

WFT = DFT ÷ (volume solids) = 150 μm ÷ 0.60 = 250 μm (10.0 mils). If thinned, divide by the thinned volume-solids fraction instead.

Answer: 250 μm (10.0 mils) WFT.

Worked example 2

A room measures 12 m × 8 m with a 3.0 m ceiling. Door and window openings total 15 m². How many litres of paint (spreading rate 10 m²/L) are needed for 2 coats on the walls?

Perimeter = 2 × (12 + 8) = 40 m. Gross wall area = 40 × 3.0 = 120 m². Net area = 120 − 15 = 105 m². Two coats = 210 m². Paint required = 210 ÷ 10 = 21.0 L.

Answer: 21.0 L (before adding a waste allowance for spray or roller loss).

Worked example 3

A two-component polyurethane coating specifies a 4:1 mix ratio by volume (Part A base to Part B hardener). How much of each part is needed to mix 15 L total?

Total parts = 4 + 1 = 5 parts. Each part = 15 L ÷ 5 = 3.0 L. Part A = 4 × 3.0 = 12.0 L; Part B = 1 × 3.0 = 3.0 L.

Answer: 12.0 L of Part A and 3.0 L of Part B. Dividing 15 L by 4 (3.75 L) is a common mistake that ruins the stoichiometric cure.

Always follow the manufacturer’s product data sheet (PDS) and MPI / SSPC surface preparation standards.
