How to Cut Hardie Tile Backer Board

Cement backer boards may seem like they run the risk of being very difficult to shape as you need.

However, there are actually a number of ways to reach the right shape, no matter what it is. In some cases, the tools you'll need to use for this may vary depending on the thickness of the board and the kind of line you need.

Here, we're covering several methods you can use for cutting backer boards like Hardie.

That way, you'll have a good idea about how to handle the process on your own, without having to bring in a professional. It's any DIYers dream.

What is Hardie Backer Board?

A Hardie Backer Board is a cement board that is designed to help with providing foundations that are sturdy and even. They are made to allow the process included in reinstalling flooring or other surfaces to be easier for those who prefer to do it themselves.

Often, cement backer board is used when you need to install things like countertops, tiling and some flooring options. Rather than laying down a ton of cement, it's much easier to use a cement backer board to provide a more even, flat surface to work with.

This is a product that is favored by DIYers as well as those who want to save time and money over the more standard options. Quality cement backer boards can also help to avoid problems with bacteria, mold and moisture that may cause havoc in other situations.

Using a Circular Saw

A circular saw can be a great tool for cutting straight lines in your backer board. While they are typically used for wood, they can also be very helpful in dealing with this type of board. If you don't own one, then you can usually find one pretty easily in a local workshop.

For the most part, using a circular saw for this purpose is going to be much the same as using it for wood. The only difference you might find is that keeping dust to a minimum is very important when cutting backer board, so you'll want a minimal amount of teeth on the blade you decide to use. Aside from that, a standard choice with carbide tipping should work perfectly well.

Try a Jigsaw

If you're in need of large cuts that are more rounded, then a jigsaw is also a fantastic option. Keep in mind that if you're going to take this choice, it will be necessary to create a hold in the board using a masonry bit to make the job run a bit more smoothly.

Keep in mind that this can also be a more difficult process if you need round holes. It's perfectly possible, but it will require much more attention and focus to get the job done correctly.

Working With Thin Sheets

As you might expect, thinner sheets are going to be a little easier to work with when it comes to these cement boards. When the board has less girth to it, you can simply score it where you want the break to be and then snap the pieces apart without too much difficulty.

With this process, you'll just need to make sure that you make use of your measurers, pencils and be very careful about where you score. Making accurate cuts (or snaps) the first time will help to avoid wasting time and product, and it will save you a lot of frustration.

Using Power Tools

If you need smaller circles, then using power tools can be an easy way to accomplish the task. You also have a few options that you can use to make sure the job is done correctly. Things like masonry bits can be extremely helpful in getting well-rounded circles.

Tips to Keep in Mind

Staying safe

When you're working with any sharp tool, whether it is powered or otherwise, it's important to make sure you are focusing on safety. With many tools, one small slip can lead to serious damage to yourself, people or other objects around you. You can never be too safe in these situations.

Wearing thick clothing is a great way to go, and making sure that you're being very careful with saws and drills is wise. Whenever possible, keep sharp objects pointed away from you and make sure you can quickly turn a saw off if you should happen to have a close call.

In addition, you'll want to make sure to protect your eyes and ears. Always wear eye protection, just in case bits of dust or other particles are moving towards your eyes. Ear plugs can also help to avoid hearing damage which can result in hearing loss over time.
