Quarter-round (or the slimmer base shoe) hides the expansion gap your floor needs around the perimeter of the room. It's the cheapest finishing piece in a floor install, but the install rule matters: it nails to the baseboard, never the floor. Choose primed for painting or unfinished pine to stain.
The perimeter finisher that hides the expansion gap where the floor meets the wall. Dirt-cheap and easy, but remember it nails to the baseboard, needs finishing, and is not a floor-to-floor transition.
- Wall gap
- Baseboards
- Expansion gap cover
Pros
- Cheapest transition in the kit and covers the required perimeter expansion gap along walls
- Primed version is paint-ready and finger-jointed pine takes stain if you want a wood look
- Long 8 ft sticks reduce joints on a straight wall run
Cons
- Bare/primed pine still needs paint or stain and caulk to look finished
- Must be nailed to the baseboard (never the floor) or it pins the floor and blocks expansion
- Pine dents easily and is not moisture-stable in bathrooms or basements
Frequently Asked Questions
- Do I nail quarter-round to the floor or the baseboard?
- Always nail quarter-round or base shoe into the baseboard, not the floor. Floating floors (laminate and most LVP) must be free to expand and contract; pinning the shoe to the floor traps it and can cause buckling or gaps.
- Quarter-round vs base shoe: which should I use?
- Quarter-round has an equal 3/4 in x 3/4 in quarter-circle profile and covers a larger gap, while base shoe is taller and thinner (about 1/2 in x 3/4 in) for a more subtle look. Use quarter-round to hide bigger expansion gaps and base shoe when you want the trim to stay low-profile against the baseboard.
