The best and easiest way to install base in your home is by using the right tools. Cutting inside corner baseboard molding with a miter saw is very easy, once you understand the type of joint you want to use. In this article, we would be teaching you how to cut baseboard outside corners with a miter saw. Also, cutting your baseboard with the right type of joint in any scenario is important to get clean finishes.
In this review, we’d guide you and give solutions to problems you may be facing while using miter saws to cut the outside corners of a baseboard.
Types Of Baseboard Joints
The first thing you should take note of when you want to cut a baseboard is the types of joints. Below are four common joint cuts:
1. Scarf Joint
In woodworking, a scarf joint is a longitudinal joint method used to join two tapered ends of a baseboard. There are different ways to cut a scarf joint, but the most common one is the plain scarf joint and it is a case where both baseboards and hardwoods are cut at the same angle in the same direction.
As such, when they overlap, they form a longer straight baseboard. A scarf joint is used for framing and straight walls and not corners.
2. Miter Joint
In this type of joint, each baseboard inside the corner is cut at a 45-degree angle, such that when joined, they form a 90-degree angle that fits perfectly against the corners of the wall.
Miter joints are at its finest when the wall meets at exactly 90 degrees. In cases where the wall is not perfectly squared achieving a perfect mitered joint may require some adjustment to your cutting angled.
3. Butt Joint
A butt joint is the simplest joint you can make as it involves cutting the baseboards or lumber to the appropriate length and butting them together.
In carpentry, the baseboard is cut at a 90-degree angle and is used best when installing a new baseboard to die directly into a door casing.
The two ends of the baseboard are placed together without any special shaping. The name comes from the way the baseboard is joined together.
4. Coped Joint
The baseboard in this type of joint is cut at a 90-degree angle for inside corner joints. The baseboard is installed by positioning one piece of the baseboard so the square end rests in the wall corner against one wall.
And then the adjoined piece is manually cut with a coping saw so that the end conforms to the contour. Coping trim outside corners is a good choice when the wall is not perfectly square.
Some questions will clear your conception about How To Cut A Baseboard Outside Corners With A Miter Saw:
What saws are recommended to cut baseboard?
We recommend using a compound miter saw like the DeWalt DWS779 (Ever Best) sliding compound miter saw with a saw table that has an excellent saw blade to cut a baseboard because of its excellent bevel angle options.
The miter and bevel features of a compound saw generally allow users to cut different angles and simultaneously use other features.
How tall should a baseboard be?
Here is a rule of thumb, when getting a baseboard, use a 3-5 inches tall baseboard for a standard 8-foot tall wall, and a 5-7 inches tall baseboard for a 10-foot ceiling.
How to cope quarter round molding?
An alternative to miter cut is the cope cut where you shape one end of the baseboard to fit the profile of the baseboard. To make a cope cut, first, you have to review the profile.
Start by cutting a 45-degree on one end of the baseboard, trace the profile, then use a coping saw to cut the profile out. Use sandpaper to complete the cut.
How to measure a baseboard for cutting?
Before you start cutting baseboards, you need to make a cut list.
Use a miter rule to take measurements and write the measurement in the center of the cut list. And an alphabet on either side say B on the right and left for butt cuts on the right and left side, or B on the right side and C on the left side for butt cut on the right side and cope cut on the left side.
Steps On How To Cut Baseboard Outside Corners With A Miter Saw
Step 1: Cut A Scarf Joint
Start by using a long baseboard for the longest part of the wall. Measure the baseboard carefully and correctly, then cut the end of one baseboard at an angle to make a scarf joint.
The scarf joint can be at any angle, but it’s recommended you use 45 degrees. Make sure the ends of the baseboard runs perpendicularly. Start by using two pieces of baseboard that are already cut at 90 degrees.
It’s important to note that in making a scarf joint you are to cut both pieces of baseboard at the same angle. But on opposite sides so that when they both pieces of baseboard laps they form a long straight baseboard.
How To Cut Various Angles For Baseboard, Cutting Crown Molding:
Step 2: Cut The Inside Joint
This is a step you use to cut a baseboard when fixing it inside or on a concave angle wall. A coped joint is best for this type of cut. Start by placing one baseboard piece against the wall at a right angle.
On the other piece, cut a 45-degree angle with a miter saw. Draw the profile of the baseboard on the piece you just cut a 45-degree angle and cut the profile at a 90 degrees angle. For a smooth inside corner, finish the profile cut with sandpaper.
Put some glue before you join the two baseboard pieces. You should use a brad nail gun with a 1.5 brad nail while closing corners.
Step 3: Cut The Outside Joint
Cutting a baseboard for outside joints or convex joints would also require you to make a 45-degree angle cut. But this time you are going to cut a 45-degree cut where the length of the part of the baseboard touching the wall is shorter than the outer part of the baseboard.
You are to cut both pieces of baseboard in the same manner and at 45 degrees. When you join both baseboards together it should form a 90-degree angle. It is recommended you smoothen out the edge for a better fit. Also, use a 1.5-inch brads nail while closing the corners.
To wrap things up, knowing how to cut a baseboard outer corner with a mitre saw shouldn’t be such a big deal when you know the right tools to use.
To get the best finishing, be keen on your measurements and marking. Also, take note that not all walls form a perfect angle, so while cutting baseboard is it important to put that into consideration.
Moreover cut corners are hardly perfect, all you need to do is cover any gap with caulk or any other equivalent.
