Which method best prevents telegraph marks from showing through painted finish trim on a wall with uneven substrate?
Answer: Apply a skim coat of joint compound to the wall before installing trim
Skim-coating the substrate behind trim areas smooths out irregularities so they do not telegraph through the paint finish on the face of the molding.
When stacking crown molding to increase visual height, how should each layer be positioned?
Answer: Flat blocking installed first to provide a nailing surface for upper layers
Installing flat blocking or build-up strips provides a solid, level nailing surface so additional crown layers are properly supported and aligned.
What is the correct way to measure for a chair rail that must return into the wall at a door opening?
Answer: Miter the end at 45° and add a mitered return piece to finish the exposed end
A mitered return uses a small piece cut at 45° to wrap the exposed end of the molding back into the wall, creating a finished termination.
When scribing a piece of trim to an irregular surface, which tool gives the most accurate transfer of the wall contour?
Answer: Compass or scribing tool set to the widest gap
A compass set to the largest gap between the trim and wall, run along the wall, scribes the exact contour onto the trim for precise fitting.
Which fastener is recommended for attaching MDF baseboard to avoid splitting near the edge?
Answer: 18-gauge brad nails
18-gauge brad nails have a smaller diameter that minimizes splitting in MDF, which is denser and more brittle near edges than solid wood.
What does 'spring angle' refer to when describing crown molding?
Answer: The angle at which the molding sits between the wall and ceiling
The spring angle is the angle at which the crown molding contacts the wall and ceiling surfaces, typically 38° or 45°, which determines miter and bevel settings.
When installing pre-hung interior doors, which shim location is most critical for proper door operation?
Answer: Behind each hinge and behind the strike plate
Shimming directly behind hinges and the strike plate transfers door load to the framing and ensures the latch aligns properly with the strike.
