Such, however, is not the case if you use [corner blocks for crown molding](https://www.creativecrown.com/product/square-inside-crown-molding-corner-blocks/) as they will spare you all the hassle and also make it possible to get an accurate installation. Here is our step-by-step guide on how to use corner blocks to achieve flawless crown molding finish.

## What Are Corner Blocks?

Corner blocks crown molding is decorative manufactured pieces that pre-manufacture. It makes the installation of inside corners much easier, making the process less involved and thereby avoiding having to do very complicated miter cuts. Crown molding corner blocks can be matched up with crown molding in a wide variety of styles and sizes.
Tools and Materials Needed
For starters, gather the following materials and tools:

Molding
Corner blocks, inside corner blocks for crown molding
Measuring tape
Miter saw or hand saw with a miter box
Level
Nail gun or hammer and finishing nails
Wood glue, if desired
Caulk and caulking gun
Sandpaper or sanding block
Paint or stain, if necessary
### Step 1: Measure Your Walls
First, you need to measure the length of your walls where you will apply your crown molding. By using your measuring tape, determine the accurate measurements and then mark a place on where you will apply it. From there, you will be able to find out how many you will use and how many corner blocks you will need.

### Step 2: Choose and Prepare Your Corner Blocks
Select the [inside corner blocks for crown molding](https://www.creativecrown.com/product/square-inside-crown-molding-corner-blocks/) which best match the crown molding style you have chosen. Once you have them, you might need to sand the edges so they fit snuggly against the wall and the molding. If you're painting or staining the blocks, do it before installing them so you aren't wasting time later.

### Step 3: Cut the Crown Molding
Cut all of your crown molding with the miter saw using 45-degree angles on each piece so all these pieces will extend to the corner blocks without leaving any spaces between them. Use all the guidelines required when cutting; the bottom edge should face the saw bed while the back should be against the fence to get a proper cut with the angles.

### Step 4: Install the Corner Blocks
Inside corner blocks are placed at the wall's corners where the crown molding would be. Make sure the corner blocks are plumb by using a level. Nail the corner blocks to the wall with the nail gun or hammer and finishing nails. To have this even sturdier, you may apply wood glue to the back of the corner blocks prior to nailing them in place.

### Step 5: Installing the Crown Molding
Once corner blocks are securely nailed in place, it's now the time to install crown molding. It should be done in such a way that edges of the corner blocks and ends of the molding are tight and aligned. Herein, nail crown molding on both sides into the corner blocks and wall; it works exactly just like what you did in step 5. Do this around every section of the room .

### Step 6: Fill gaps and nail holes
Once the molding is all laid in, look for any gaps that have appeared around the molding as well as nail holes. Caulk in these gaps, then smooth out with your finger or caulking tool to get a nice finish. If you are facing nail holes, apply a wood filler patch, wait for this to dry and then sand out to make it smooth with the wall.
Step 7: Finishing Touches
Once everything is dry, you can finish the project with paint or stain. Depending on how much of the corner blocks you painted or stained above, you may just need to touch up your crown molding. Let everything dry completely before you return furniture to the room or decorate.

## Tips for Success
Take Your Time: Mistakes occur when individuals rush through measurements and cuts.
Double-check everything: Always double-check your measurements and angles before you cut or nail.
Practice on scraps: If you're not certain of your cuts, it can be very helpful to cut scrap pieces of molding first.
