Nailing quarter round to baseboard can be a daunting task for beginners, but with the right techniques and tools, it can be a breeze. This guide will walk you through the process step-by-step, ensuring a professional finish that will enhance the look of your room.
Understanding Quarter Round and Baseboard
Before we dive into the nailing process, let's understand what quarter round and baseboard are. Baseboard, also known as skirting board, is a protective covering for the bottom of your walls where they meet the floor. Quarter round, on the other hand, is a small, decorative molding that fits over the joint where the baseboard meets the floor. It adds a touch of elegance and hides any gaps that might be present.
Tools You'll Need
- Miter saw or miter box with backsaw
- Nail gun or finishing hammer
- Brad nails (1-1/4" or 1-1/2") or finishing nails
- Tape measure
- Pencil
- Claw hammer (for removing baseboard)
- Safety glasses
Preparation: Measuring and Cutting
Before you start nailing, you need to measure and cut your quarter round pieces. Measure the length of your baseboard, then subtract the width of your quarter round (usually 1/4" or 1/2") to find the length of your cuts. Use a miter saw or miter box to cut 45-degree angles on the ends of your quarter round pieces. Remember to cut inside angles for corners and outside angles for ends.

Removing the Old Baseboard (if necessary)
If you're replacing old baseboard, use a claw hammer to carefully pry it off the wall. Start at a corner and work your way along the baseboard. Once it's off, clean up any nails or debris left behind.
Nailing the Quarter Round
Using a Nail Gun
If you're using a nail gun, set it to shoot 1-1/4" or 1-1/2" brad nails. Hold the quarter round piece in place, with the angled end against the wall and the other end against the baseboard. Shoot a nail through the quarter round and into the baseboard. Repeat every 4-6 inches along the length of the piece. Use a nail set to sink the nails below the surface, then fill the holes with wood filler.
Using a Finishing Hammer
If you're using a hammer, follow the same process as with a nail gun, but instead of shooting nails, you'll hammer them in. Be careful not to split the quarter round. Once you've nailed the piece in place, use a nail set to sink the nails, then fill the holes with wood filler.

Finishing Up
Once you've nailed all your quarter round pieces in place, use sandpaper to smooth out any rough spots. Then, apply a coat of paint or stain to match your baseboard. Let it dry, and your quarter round is ready to show off!
Nailing quarter round to baseboard might seem like a complex task, but with these steps, you're well on your way to a professional finish. Don't forget to always prioritize safety when using power tools and working with nails. Happy nailing!
