A DIY Guide to Installing Fiber Cement Siding

Are you thinking about giving your home a fresh new look this year? Then fiber cement siding, also known as cement board siding, is an awesome choice—it’s super durable and can give you that classic wood shingle style without all the upkeep. With a little preparation and some guidance, you can absolutely tackle this fiber cement installation yourself and save a lot of cost. This step by step article will guide you through the key steps, drawing on techniques you’d see from a master like general contractor Tom Silva, and you can follow along with a helpful video for a closer look.

Step 1: Prep Your Wall for Fiber Cement Siding Installation

First things first: prepping your wall. You’ll want to find and mark all the studs so you know exactly where to nail your fiber cement. This is all about making sure everything is secure. Then, you’ll install a Z-channel and flashing. Think of this as your first line of defense against water—it’s crucial for keeping moisture from sneaking behind your new siding. By applying caulk to your corners and push that flashing right into it for a solid seal.

Step 2: Install the First Rows of Cement Board Sliding

Next up is the filler strip. This is a clever trick to create a nice, flared-out look for your first row of shingles while also filling that gap behind the siding. Remember to cut the strip a little shorter than the space to allow for some breathing room and raise it slightly above the flashing. This helps keep everything dry and looking great.

Now for the siding itself! The video features a product that lets you install several “shingles” at once, which is a fantastic time-saver for your fiber cement installation. As you nail your first piece into the studs, use a chalk line to make sure it’s perfectly straight. Here’s a pro tip: when you get to the next rows, make sure none of the siding joints line up. This is a super important step to prevent any water from getting in. You can easily cut the fiber cement siding by scoring and snapping it with a utility knife and a straight edge.

Step 3: Finishing Tricky Spots from your Fiber Cement Installation Wall

Finally, for any tricky spots like under a window, you’ll just use individual pieces of siding. Secure them with stainless steel nails, and you’re good to go!
