Frequently Asked Questions
Why is shoe molding (quarter round) recommended with new flooring?
Floating vinyl plank and laminate floors require a 1/4" to 3/8" expansion gap along perimeter walls. Standard 1/2" baseboards barely cover this gap. Adding flexible shoe molding (3/4" × 1/2") covers the gap seamlessly and contours to uneven subfloors.
What is the difference between coping and mitering inside corners?
Mitering cuts two 45-degree angles; however, drywall corners in homes are rarely square (often 87° to 93°), causing miter joints to open. Master carpenters use a coping saw to cut the profile of one board, allowing it to overlap the perpendicular board for an airtight joint that never gaps during seasonal wood movement.
What nail size should be used for baseboards?
Use 2-inch or 2-1/2-inch 15-gauge or 16-gauge finish nails driven with a pneumatic nail gun into wall studs (spaced every 16 inches) through the bottom sole plate.
Should you choose primed MDF or finger-jointed pine?
Primed MDF is perfectly straight, knot-free, inexpensive, and takes paint beautifully, making it ideal for painted trim. Solid wood or finger-jointed pine is required for wet areas (bathrooms) or when stained wood grain is desired.
