Q1. 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?
Worked Explanation: 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.
Q2. 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?
Worked Explanation: 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.
Q3. 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?
Worked Explanation: 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.
