Quarter round molding is used to cover the joints between the baseboard and the floor, as well as the joints between the baseboard and the walls. When installing quarter round molding in inside corners, it’s important to cut the molding at a 45-degree angle so that the two pieces fit together perfectly and form a smooth joint. However, this is not enough. If you place the two on top of each other and trim them to 45 degrees, there will be a visible gap at the top of the molding. This is because the molding is thicker at the top than it is at the bottom. So, in addition to cutting each piece at a 45-degree angle, you also need to bevel the bottom of the piece that will be on top. This will create a clean, tight joint.
To bevel the molding, you can use a miter saw or a table saw. If using a miter saw, set the blade to a 45-degree angle and then tilt the saw blade to a 15-degree angle. This will bevel the bottom edge of the molding. You can then cut the molding to length. If using a table saw, set the blade to a 45-degree angle and then raise the blade so that the bottom of the blade is just touching the bottom of the molding. You can then run the molding through the saw to bevel the bottom edge. Once the molding is beveled, you can cut it to length and install it in the inside corner.
Here are the steps on how to cut quarter round inside corner:
1. Measure and mark the length of the molding you need.
2. Cut the molding to length using a miter saw or a table saw.
3. Bevel the bottom edge of the molding using a miter saw or a table saw.
4. Apply a thin bead of caulk to the back of the molding.
5. Press the molding into place in the inside corner.
6. Use a nail gun to secure the molding in place.
7. Fill any gaps between the molding and the wall or baseboard with caulk.
How to Cut Quarter Round Inside Corner
Cutting quarter round inside corners requires precision to ensure a seamless and professional-looking finish. Here’s a step-by-step guide to help you cut and install quarter round inside corners:
-
Measure and Mark the Corner: Determine the length of the quarter round needed for each side of the corner. Mark the measurements on the quarter round using a pencil or measuring tape.
-
Cut the First Piece: Cut the first piece of quarter round straight to the measured length.
-
Mark the Miter Angle: Place the first piece against the wall in the corner. Mark the point on the quarter round where it intersects the adjacent wall. This will be the location of the miter cut.
-
Set Up the Miter Saw: Adjust the miter saw to a 45-degree angle.
-
Make the Miter Cut: Hold the quarter round securely against the miter saw fence and align the marked point with the saw blade. Make a smooth cut through the quarter round.
-
Cut the Second Piece: Repeat the process for the second piece of quarter round, ensuring that the miter angle is cut in the opposite direction to create a 90-degree inside corner.
-
Dry Fit the Pieces: Place both pieces of quarter round into the corner to ensure they fit together correctly. Adjust the miter angles if necessary for a tight fit.
-
Apply Adhesive and Install: Apply a generous bead of construction adhesive to the back of both quarter round pieces. Carefully press the pieces into place in the corner, ensuring the miters are aligned. Wipe away any excess adhesive.
-
Secure with Nails: If desired, you can also secure the quarter round with small finish nails. Drive the nails through the quarter round into the wall at an angle to hide them.
