One of the problems with cutting cement board is that you can’t get a good grip on the knife so you will end up ruining your blade instead of opening up the board and creating a nice clean cut.
You need to figure out a way to make a more efficient cut so that you can avoid this situation altogether.
One way is by using a utility knife, which has no problem slicing through other materials than concrete.
The trick in using it to effectively make this process happen is learning how to hold it correctly and properly apply it at just the right angles.
Here we will learn how to cut cement board with a utility knife.
Step By Step – How To Cut Cement Board With A Utility Knife
- Cement Board
- Utility Knife
- Tape Measure
- Marker or Tape
Budget: $30 – $50
Duration: 15 – 20 Minutes
Measure your board and mark out a cutting line on it.
The first step in this process is to mark out how far the blade must go into the board.
After you have marked out the cutting line, you need to make sure about where the blade will stop by drawing a line across it.
Where the blade stops must be at least one inch from where it starts.
Inside the cutting line, you need to apply a 45 degree angle so that the edge of it meets the board at an angle.
Hold the utility knife horizontally with one hand and then pull the blade out with your other hand until it’s even with where you marked off on your board.
After you have applied this 45 degree angle to the blade, place it inside of your cutting line and make sure that both ends are at a 90 degree right angle to each other.
Make sure that all of your corners are at right angles in order to make for a clean cut.
After this, you need to draw over the cutting line.
Then you can remove the excess cement board.
Now you have a clean cut that will make for an easier install process.

Step By Step – How To Cut Cement Board Without Dust Using A Utility Knife
To keep the dust out of your work area you need to keep it clean by creating some distance between yourself and the cement board.
You can use a ruler or a tape measure to create a guide for you in order to get your board at the right level.
You can then use this as a guide to mark off where you want the cut to be made giving you plenty of room for error.
You can then use a utility knife or a coping saw to start cutting.
You can make along the lines of your cut with the blade. Move it in the direction you want the cut to be made while you are cutting. Once you have one side done just move onto the next side and continue until both sides of your board are cut out.
This is a great start to keep on cutting cement boards without dust.
Step By Step – How To Cut Holes In Cement Board Using A Utility Knife
You can measure out your hole and mark it with a pencil.
You then poke the center of the hole with a nail or something similar.
You can then use a tape measure and a pencil to get the right distance for your cuts.
You can then measure outside of these lines that you just drew so that you have more room for error when cutting.
Make sure to only go halfway through while doing this because if you go all the way through your cement board it will not cut well and will be difficult to cut out the rest of it.
Step Five: You want to make sure that you have enough room to get your saw blade through the board.
Step Six: Now you just need to cut a small section of the board at a time and then pry it out with your hands.
Step Seven: Once your board is out of the way cut another section of board and repeat until all of the board is cut out.
With this, you now have a great circle cut for your cement board with just using a utility knife!
