5 Ways To Cut Inside Corners On Quarter Round

4 Simple Steps to Cut Perfect Molding Corners

Quarter round is a type of molding that is used to cover the joint between two surfaces, such as the floor and the wall. It is typically made of wood or plastic, and it comes in a variety of sizes and shapes. One of the most common types of quarter round is inside corner quarter round, which is used to cover the joint between two walls. Cutting inside corners on quarter round can be a bit tricky, but it is not impossible. With a little practice, you can get the hang of it and create beautiful, professional-looking results.

To cut inside corners on quarter round, you will need a miter saw. A miter saw is a type of saw that is used to make angled cuts. It is important to use a miter saw for this project because it will help you to make precise cuts. If you do not have a miter saw, you can rent one from your local hardware store. Once you have your miter saw, you can begin cutting the inside corners on your quarter round.

To cut an inside corner on quarter round, you will need to first measure the length of the joint that you will be covering. Once you have the measurement, you can cut two pieces of quarter round to the desired length. To cut the inside corner, you will need to place the two pieces of quarter round on the miter saw and cut them at a 45-degree angle. Once you have cut the inside corner, you can attach the two pieces of quarter round to the joint using adhesive or nails.

Measure and Mark the Inside Corner

Determining the angle and length of the corner cut requires careful measurement and marking. Follow these steps to accurately lay out the cut:

Step 1: Determine the Angle

Measure the angle between the two walls forming the inside corner using a protractor or digital angle finder. If the angle is not exactly 90 degrees (a square corner), the quarter round will need to be beveled to match the angle.

Step 2: Measure and Mark the Length

Measure the distance from the point where the walls meet to the edge of the room. This measurement represents the length of the quarter round that will be cut for the inside corner. Mark this length onto the quarter round using a measuring tape and pencil.

Step 3: Draw the Bevel (If Necessary)

If the inside corner is not 90 degrees, it will be necessary to draw a bevel on the quarter round. Determine the angle of the bevel by dividing the measured angle by 2. For example, if the inside corner measures 80 degrees, the bevel angle would be 40 degrees.

Inside Corner Angle Bevel Angle
80° 40°
75° 37.5°
60° 30°
45° 22.5°

Using a protractor or bevel gauge, draw a line at the appropriate bevel angle from the mark you made in Step 2. This line will guide you when cutting the quarter round.

Make a Test Cut

Before you start cutting the inside corners of your quarter round, it’s a good idea to make a test cut on a scrap piece of material. This will help you to get the hang of the technique and to make sure that you have the right saw blade and settings.

To make a test cut, follow these steps:

  1. Set the saw blade to the correct angle. The angle will vary depending on the thickness of your quarter round, but it is typically between 45 and 60 degrees.
  2. Clamp the scrap piece of material to your work surface.
  3. Hold the saw firmly and make a cut through the material.
    **Make sure to keep your fingers out of the way of the blade.**
  4. Inspect the cut to make sure that it is clean and precise.

Once you are satisfied with your test cut, you can proceed to cutting the inside corners of your quarter round.

Quarter Round Thickness Saw Blade Angle
1/4 inch 45 degrees
3/8 inch 50 degrees
1/2 inch 60 degrees

Fill any Gaps

Any gaps between the quarter round and the wall can be filled with either caulk or wood filler. Caulk is a better choice for small gaps, while wood filler is better for larger gaps.

Using Caulk:

  1. Apply a bead of caulk along the gap between the quarter round and the wall.
