Cut the Miter to Length

  • Hold the baseboard in place and mark the backside at the corner.
  • Cut the piece to length at the predetermined angle for an exact fit.

Which is the correct way to construct a 45 angle?

45 Degree Angle Construct a perpendicular line. Place compass on intersection point. Adjust compass width to reach start point. Draw an arc that intersects perpendicular line. Place ruler on start point and where arc intersects perpendicular line. Draw 45 Degree Line.

How to Cut Coped Joints

This method is much harder than a miter cut. Still, it provides a better fit, so it’s definitely worth the effort. A baseboard serves as a half of a coped corner, which fits flat against the wall, without bevel, and the jigsaw is the perfect tool for this cut. 

Follow the steps to cut a coped joint or coping corner cut joints: 

  1. First, you need to cut the baseboard in length, using a bevel cut would be best, so it exposes the grain end of the baseboard. That way, the jigsaw has more working material.
  2. After that, you need to do a back-cut using the jigsaw, alongside the decorative baseboard’s curve.
  3. Then, ensure the workpiece is safely clamped down on a bench, ideally by making use of bench vise.
  4. Make a curved, 45- degrees angle cut with the jigsaw, to the baseboard’s backside, alongside its surface.
  5. Use sandpaper to finish or file the baseboard. Make sure the other corner fits as well. Ensure that the socket from the back cut is fitting the face of the other side of your baseboard.
  6. Use some brad nails measuring around 1 1/2 inch (with some glue) to install and secure the baseboard securely.
  7. Finally, add paint and caulking around any slight gaps or joints if necessary to pretty your new trim up. 

What is the difference between vinyl and rubber base?

THERMOPLASTIC RUBBER (TR) AND THERMOPLASTIC VINYL (TV) Thermoplastic rubber and thermoplastic vinyl cove bases are manufactured essentially in the same way. Most TPR wall base is 92 percent to 98 percent vinyl, and is manufactured in either a two-part method (wear and core layers) or homogeneously.

3. Measure Inside of Door Frame

Measure the inside of the door frame at the top, middle and bottom. Take the largest of the three dimensions and add 1/2 inch to allow an average of 1/4-inch spacing from the door trim to the door frame edge. Note this measurement on a piece of paper and label it. This measurement will be from the short end of the left-side 45-degree miter cut to the short end of the right-side 45-degree miter cut.

Things You Would Need To Cut Trim Angles

  • Miter Saw: While there are various types of miter saws available, we recommend a bevel sliding compound miter saw with a bevel sliding of at least 45 degrees in both left and right and a bevel maximum of 45 degrees.
  • Personal Protective Gear: This includes anti-cut heat resistant work gloves, earplugs, and protective eyewear. As miter saws have a powerful motor and a high RPM, it creates a lot of sawdust. The sawdust can inhibit vision and irritate the skin. It is damaging if it enters the eye. The blade is sharp, and there is a danger of injuring oneself. Miter saws can be noisy, and it is recommended to wear earplugs for protection. 
  • Angle Measure: We will use this to measure the angle required for the trim cut. 
  • Baseboards: The kind of baseboard you use will depend on your project. They will be cut down to make the trim cuts.
  • Tape measure and Marker: You can use any standard marker that writes on different materials. It will be used to mark the points where the trim angle will be cut. The tape measure will be used to measure the length of the baseboard to be cut.
  • Wood Filer or Sander: This will be used to make minor adjustments to the cut pieces of wood. Any standard saw sander and filer can be used. 
  • Wood Filler: This is a synthetic product which is equivalent to white cement in construction work. The wood filler can fill any gaps that may occur while placing the trim angle cuts.

What do you cut wood trim with?

Miter Saw—A much better saw to use for cutting trim molding. Also called a 'chop saw,' this tool has a fine toothed blade that you pull down on the work piece. You can cut in different angles. Radial Arm Saw—A variation of the chop saw, this one is ideal for precise cuts.

What is a 45 degree triangle called?

A 45 – 45 – 90 degree triangle (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of. Note that it’s the shape of half a square, cut along the square’s diagonal, and that it’s also an isosceles triangle (both legs have the same length).

How to Cut Baseboard Corners with a Hand Saw

If you don’t have a circular saw, don’t worry. You can still cut baseboard corners using a hand saw and a miter box, instead of forking out the cash for circular saw or a high-priced sliding compound miter saw.

However, you’ll need some glue, an adjustable bevel, some wood screws, a screwdriver, a carpenter’s square, and 1×6 and 1×4 lumber.

Follow the instructions closely: 

  1. Cut two 12-inch lengths of 1×6 lumber and 12-inch length of 1×4 lumber. The type of wood doesn’t matter, but if you can, get oak or fir. It’s more important to get wood which is warp-free, and completely straight.
  2. Apply wood glue along the two long edges of the 1×4 lumber and place it flat on the work table. Place the 1×6 lumber upright against every edge and use a screwdriver and ½ wood screws to screw the 1×6 in the 1×4 lumber. When finished, you’ll have a four-inch open box. 
  3. Place the bevel to 45- degrees and mark the top edge angles on the two sides of the box with a pencil. Use a carpenter’s square to draw a perpendicular line on the outside of the box, from the angled line intersection to the bottom of the makeshift box.
  4. Align your handsaw with the angled marks at the boxes’ top edges, and cut through the sides top to bottom. Make sure the ends of the hand saw are aligned to the perpendicular lines on the side.
  5. Using the box and the handsaw to cut the baseboard. Keep the baseboard up against the side of the box, using the mark on the baseboard to show you the length of the kerf in the box. Hold the saw within the kerf as you cut the baseboard. 

Note: If this is too complicated for you, simply buy a miter box at a supply store which can produce similar results to using a miter saw, but without the added financial investment.

Also, the best type of saw for this job is dovetail or backsaw, but pull saws will also work. 

Warnings

  • Operating a saw is dangerous. Take proper safety precautions such as eye protection and a dust mask. Keep loose hair, clothing, and jewelry out of the way.

Step II: Cutting the Trim

Prep

When it comes to cutting the trim, using a regular miter saw can be difficult, or in some cases, impossible. With a standard miter saw, you’ll need to make your cut vertically through the trim. For thicker pieces of trim, this may not be realistic.

But, with a compound miter saw, you’ll be able to lay the trim flat against the fence of the saw, and adjust the head of the saw to the angle you need to cut. This makes cutting trim significantly easier.

A compound miter saw is something to consider investing in. But, if you don’t want to buy one, renting or borrowing one for the day will be perfect for the sake of this project.

Once you’re ready to begin cutting, you’ll want to put on your safety goggles and work gloves. You may also want to consider wearing earplugs.

First Cut

In this example, we’re cutting trim for a 90° inside corner. You’ll need to cut each piece of trim at a 45° angle so that when the two pieces butt together, they’ll create the perfect 90° angle you need to create a polished look. So, your first step is to set the saw to 45°.

Next, place the trim against the fence, so that the top of the trim is in contact with the fence. Since we’re cutting for an inside corner, you’ll want to make your cut on the right side of the piece of trim.

With the trim firmly against the fence, turn the saw on and make your first cut. Always keep the hand you’re holding the trim with at least 6” away from the blade of the saw.

Second Cut

Next, you’re going to repeat the process with the other piece of trim you’ll need to complete the corner. However, instead of holding the top of the trim against the fence, you’re going to do the reverse of that with this second piece. Place the trim against the fence so that the bottom of the trim butts up against the fence.

Now, you can make your second cut.

Outside Corners

If we were cutting trim for an outside corner instead of an inside corner, the entire process is identical. However, instead of angling the cut from front to back, the cut angles from back to front. To do this, you’ll simply cut from the left side of the trim, instead of the right side, as we did for an interior corner.

For other angled cuts, it’s as simple as setting your saw to cut the appropriate angle, and working from either the left or right side of the wood in order to produce a piece of trim for an inside or outside angle.

For An Acute Angle

Let us assume that you need to cut a baseboard trim angle cut of 90 degrees.

Step 2

First, we need to calculate the setting for the miter saw. We use the following formula: 

Whatever is the angle of the corner, divide it by two. The resultant angle will be the setting angle for your miter saw. Therefore, for a 90-degree corner, the angle setting for the miter saw will be 90/2 = 45 degrees. Set the miter saw to 45 degrees. Fix the baseboard in position on the miter saw, using the adjustable jig.

Step 3

Turn on the miter saw. Cut the baseboard at the fixed 45 degrees. Turn off the miter saw. Readjust the saw to zero degrees. Adjust and fix the baseboard to the marked spot so one side of the trim angle can be cut using the jig. Turn on the miter saw and cut the baseboard. Repeat the process one more time so that you have two pieces of baseboard with a 45-degree miter cut. Turn off the miter saw. Remove the baseboard pieces. Using the filer or sander, smoothen the cut angles if required.

We now have cut a trim angle for a corner of 90 degrees. Check it with the corner. Use a wood filler to fill in minor inaccuracies if necessary.

Dealing with Common Problems and Imperfections

In a perfect world, every wall is straight, every corner is a perfect 90-degrees, and every floor is level. The reality of construction means there are always minor imperfections in new and older homes.

Here are a few tips and fixes to give you professional results for those little challenges you’ll find when you install baseboard floor molding.

Out of Square Corners

When corners aren’t square, the baseboard molding will magnify the problem by showing a misaligned seam or a big opening due to tilting. To avoid these issues, check the corner with a square to see if it is indeed 90-degrees.

If you have an out-of-square situation, you’ll need to do a bit of trial and error. First, use some scrap baseboard to check the corners to see how they fit. If they are not square, use the scrap pieces to adjust your miter saw. Cut two ten-inch pieces and use an educated guess to adjust your miter saw at an angle higher or lower than 45-degrees depending on the corner. Fit them together and make new cuts until you achieve the right angle on the saw. Chances are, the adjustment will be a half degree one way or the other. Now you can cut and install the pieces.

For a baseboard that tilts at a corner, you can drive a drywall screw at the bottom of the wall at the corner. Using a test piece of molding, adjust the screw in or out, so the molding rests against it flush with the wall and the other piece of molding.

Tilted Baseboard Molding

Tilted Baseboard Molding

Typically, installers will leave a gap between the floor and the bottom of the drywall. If you try and attach the baseboard by nailing at the base, the nails won’t hit anything or will draw the bottom of the baseboard, leaving a gap at the top.

To remedy this situation cut spacers the height of the gap. Usually, scrap ½ in. plywood or other material will work. Place pieces in the gap to act as a support for the bottom of the baseboard. You don’t have to attach them, but they will prevent the baseboard from sliding inward as you nail.

Protruding Seams

To avoid protruding seams, test for fit before nailing them. Also, as mentioned earlier, use a scarf joint positioned at stud so you can fasten it securely. This will help keep them from popping out later.

Improper Measurements

The only cure for improper measuring is money because you’ll need to buy more material. Always cut a little long so you can sand or use a coping saw to make an exact fit. The adage, “measure twice, cut once,” holds true for any home improvement project, including floor molding.

Gaps and Crooked Walls

Sometimes a wall is crooked due to a misaligned stud, settling, or poor drywall installation. It’s rare that every baseboard will fit snug against a wall or in the corners. If you’ve tried some of the techniques above and still have gaps, your last remedy is to fill them with caulk or a wood filler. Follow the manufacturer’s instructions for use and clean up. You can paint it the color of the baseboard or the wall for a professional look.

this was done last night. still needs some work – wood filler in the small gaps and stuff. since my house is old, many of the walls are crooked so some of the “boards” are not perfectly aligned! but i can make them so they’re not noticeable 🙂

How to Repair Gaps Along Moldings

Molding and trim generally look best when they are fitted tightly to walls and ceilings. Small gaps show shadow lines and leave the trim looking unfinished.

To fill gaps between moldings and the ceiling or walls, apply a bead of siliconized-latex caulk. This is flexible enough to ride out any movement caused by moisture changes.
