Crown molding is a beautiful way to add detail and character to a room. But, installing crown molding can be tricky, especially concerning corners. The solution?
The corner blocks for crown molding. These small pieces of wood can create a seamless look when two pieces of crown molding meet at a corner.
Here, we will walk you through the steps to how do you make crown molding corner blocks so you can add a professional touch to your next home improvement project.
Here Is How Do You Make Crown Molding Corner Blocks
Materials Needed
To construct crown molding corner blocks, you will need the following materials:
Wood: You will need a piece of wood at least 1 inch thick and wide enough to cover the crown molding corner. The length of the wood will depend on the size of your corner.
Saw: You will need a saw to cut the wood to the desired shape. A miter saw or circular saw is recommended.
Sandpaper: You will need sandpaper to smooth the edges of the wood.
Stain or paint: You will need stain or paint to finish the wood.
Measuring the Corner
The first step in making crown moulding corner blocks is to measure the corner where the crown molding will be installed. This is important to ensure that the corner blocks fit properly and form a seamless transition.
To measure the corner, use a tape measure to determine the length and height of the corner. The length is the distance between the two walls at the corner, and the height is the distance from the floor to the ceiling. Record these measurements so you can cut the wood to the correct size.
Cutting the Wood
Once you have measured the corner, it’s time to cut the wood accordingly for the corner block. You will need to cut two pieces of wood for each side of the corner.
To cut the wood, use a saw to create a triangular shape with one angle at 90 degrees. The other two angles will be the same as the angle of the corner where the crown molding will go. Use the measurements you recorded earlier to create the triangular shape.
After you have trimmed the wood and shape, use sandpaper to smooth out the edges. This will help create a seamless transition between the corner blocks and the crown molding.
Sanding and Finishing
Before installing the outside corner blocks, it’s important to sand and finish the wood. This will not only create a smooth surface, but it will also give the wood a professional look.
Start by using coarse sandpaper to remove any rough spots on the wood. Then, switch to fine sandpaper to create a smooth surface. Be sure to sand the edges of the wood as well.
After sanding, you can finish the wood with stain or paint. If you choose to stain the wood, apply the stain with a brush or cloth and wipe away any excess. Allow the stain to dry before applying a second coat if necessary.
If you paint the wood, apply it with a brush or roller and allow it to dry completely.
Installing the Corner Blocks
Now that you have measured, cut, sanded, and finished the corner blocks, it’s time to install them. Here are the steps to follow:
- Apply a small amount of construction adhesive to the back of the corner block.
- Align the corner block with the corner to be covered by crown molding.
- Use a nail gun or finishing nails to secure the corner block to the wall.
- Repeat the process for the other side of the corner.
- Install the crown molding as you normally would, butting it up against the corner blocks.
Using Crown Molding Corner Blocks
With the crown corners in place, you can now proceed to install the crown molding. The corner blocks provide a seamless transition between the two pieces of crown molding, creating a professional and polished look. Plus, corner blocks save time and frustration in installation.
It’s important to note that not all corners require corner blocks. If the corner angle is not sharp or the walls are not at a perfect 90-degree angle, you may be able to install the crown molding without using corner blocks. But, corner blocks can be a game changer for corners that require a precise fit.
