Question 1

What is the recommended nail schedule for attaching solid wood baseboard (3/4" thick) to wall studs?

Accepted Answer

8d finish nails at 16" O.C.

Answer

8d finish nails at 16" O.C. (aligned with studs) provide adequate holding power while the small head minimizes surface damage requiring filling.

Question 2

Which technique prevents paint from bridging the gap between trim and wall, making the trim difficult to remove later?

Accepted Answer

Applying painter's tape during painting and removing before full cure

Answer

Applying painter's tape along the wall edge during painting and removing it before the paint fully cures creates a clean paint line without paint bridging the gap.

Question 3

When installing a raised-panel wainscot kit, which component is installed last?

Accepted Answer

Cap rail

Answer

The cap rail is installed last because it sits on top of the assembled stiles and panels, capping the system and covering any gaps at the top.

Question 4

What is the maximum gap acceptable between a door bottom and a finished hardwood floor before a threshold or door sweep is required?

Accepted Answer

3/8 inch

Answer

A gap of 3/8 inch or greater at the door bottom typically requires a threshold or door sweep to prevent drafts, pests, and visible light gaps.

Question 5

When finish-nailing through the face of hardwood trim, what should be done immediately after driving each nail?

Accepted Answer

Set the nail slightly below the surface with a nail set

Answer

A nail set is used to drive the nail head slightly below the wood surface, creating a small depression that can be filled for a smooth, professional finish.
