Introduction

Cement board is one of the most versatile materials you can use for do-it-yourself (DIY) projects. It’s durable, easy to work with, and reasonably priced. You can use it as a backing for tile, as a substrate for countertops, or in a host of other applications.

One of the most common questions we get about cement board is how to cut it. Keep reading to learn some tips and tricks for cutting cement board like a pro.

Tools and Materials Needed

If you’re working on a tiling project that involves cement board, you’ll need to know how to cut it properly. Cutting cement board is different from cutting other types of tile backer board, like gypsum board. Cement board is made of Portland cement, sand, and water, and it’s much harder than gypsum. That means you can’t just use a utility knife or pair of scissors to cut through it. You’ll need to use the right tools and materials to get the job done right.

Here are the tools and materials you’ll need to cut cement board like a pro:
-A measuring tape
-A pencil
-A straight edge
-A wet saw with a carbide-tipped blade (a circular saw with a diamond blade will also work)
-Cement board screws
-Cement board tape
-Thin set mortar
-Tile grout

Cutting Cement Board

Cement board is a necessary component in many tile jobs, but it can be difficult to cut. Here are a few tips on how to get clean, consistent cuts in cement board:

-Use a sharp blade: A dull blade will make it difficult to get clean cuts in cement board. Be sure to use a new or sharpened blade in your saw.
-score the surface first: Use a scoring tool or utility knife to score the surface of the cement board before you make your cut. This will help prevent the blade from slipping and create a cleaner cut.
-Use a straightedge: When cutting cement board, be sure to use a straightedge or level as a guide. This will help you get a straighter, more consistent cut.
-Use protective gear: Cement board dust can be harmful to your lungs, so be sure to wear a dust mask when cutting. Also, wear gloves and eye protection to avoid injury from flying debris.

Finishing Up

After you have made all of your cuts, it is time to finish up.

First, you will want to sand down the edges of the cement board. This will help to smooth them out and help to prevent any sharp edges from cut pieces.

Next, you will want to clean up the area where you have been working. This includes sweeping up any dust or debris that has been created from cutting the cement board.

Finally, you will want to apply a sealant to the cut edges of the cement board. This will help to protect them from moisture and will also make them easier to clean in the future.
