However, most walls do not form a perfect 90-degree angle, so you will notice gaps in the connection. The way you cut depends on whether you need to cover an inside corner, which is concave and between connecting walls, or an outside corner, which is convex and juts out from the walls. If you can't get the angle right, fill in the gaps with paintable silicone caulk, then paint over it to hide it. You can paint caulk the same color as the trim so anyone who comes into your home is hard-pressed to spot the flaws in the miter cut.

Decorative mouldings are used to add a traditional style to complement any room, providing the perfect finishing touch. To create the mating piece of trim, the angle gauge needs to point to the exact opposite angle from what you used earlier. With more than four years of experience, he specializes in high-end real estate development and construction. To use the bevel, place the base end firmly against 1 wall, open up the tool, and place the blade end against the other wall. Any gaps in the trim can be filled in with caulk, but you may not even need to do this if you measure and cut carefully.Use a pencil to mark the angle of the first board onto the second board as a guideline for the next cut. To cut an outsider corner trim, turn your miter saw clockwise to 45 degrees and cut your first trim piece to the left of the saw blade. Although each piece of trim needs to be cut to a specific length, overestimate the length of trim you need to ensure you have enough to cover the corner. You can use short pieces of trim to form the corners as needed, then connect them to longer pieces of trim.

For the initial angle, turn the base clockwise until the saw points to the 45-degree angle mark, which you can see on the angle gauge beneath the base. For trim with multiple corners, such as the top and bottom pieces framing a window, cut the opposite end of the original trim. Use a pencil to mark the angle of the first piece onto the second one as a guideline for the next cut. To get a better sense of this, hold the trim up against the wall corner where you plan on installing them. Use a tape measure on the wall, but also hold the piece of trim to the wall to get an idea of how it will fit.To cut an inside corner trim, you’ll use the same process, then make another cut with a coping saw to make a more precise angle. If the boards don't connect cleanly or rest flat against the wall, caulk can cover up the imperfections. jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
