Are you interested in using cement tiles in your next project? Check out everything that we learned while installing cement tiles during our shared boys’ room renovation.

I cannot believe we only have 2 weeks left in the challenge!!! We are actually right on schedule to finish on time – I’m so relieved.

We have tackled almost all of the big projects and mostly just have finishing work to do.

Honestly, I’ve been completely slacking with some of the design elements these past two weeks and really need to pull it together. What good is a finished room with no decorations??

If you’re just stopping by today or if you want a quick refresher on what we are doing, head over to the previous weeks to see where we started and the progress we have made so far!

Learn how to install cement tiles in this One Room Challenge update! These black and white patterned cement tiles look great around a natural brick fireplace.

This week was all about finishing the interior of the fireplace and installing the cement tile hearth.

I posted earlier this week about my newfound love for cement tile (and where to use it in your home). Well, I thought I loved the tile when it was just in the box.

I’m completely blown away by how it looks installed and finished. This little unfinished area has been bugging me since we moved in almost a year ago. I can’t imagine a more perfect tile for the space. I may even sleep right there on it.

Let’s back up. Here is what we started with:

Yes, that is insulation falling out of the top. Scary, right?

Here is what it looks like today:

How to Install Cement Tiles in a Fireplace Hearth

Step 1: Prep the Fireplace Hearth

First, we started by creating a level surface from the hearth to the inside of the fireplace. Since the hearth was already concrete and level, we used quikrete to level the inside of the fireplace with the hearth.

I found this full guide on how to use quikrete which seems pretty extensive. For our purposes, we poured in the concrete and used concrete tools to level the surface.

Next, we painted the interior bricks with a satin black enamel paint. The bricks were so damaged we couldn’t clean or salvage them. Luckily this paint only required one coat!

Lastly, for the prep work, we used a piece of plywood to fill in the opening to the top of the chimney to hold up all the debris and keep the kids from trying to climb the chimney looking for Santa. {This still needs painted black}

Already doesn’t look like it’s straight out of a horror movie anymore!

Step 2: Prep the Cement Tiles + Measure

Next, it was time for the tile!

We chose this gorgeous tile from The Tile Shop! I wanted something that looked as though it could have been original to the house – so something a bit more traditional looking.

{But, if you aren’t a fan of that tile, I linked to TONS of other cement tile styles in this post to choose from}.

The tile came in, and we were all set to install it when we realized we needed tile edging to separate the tile from the wood.

There are several ways you can separate tile and wood, but we went with an aluminum edging trim that of course had to be specially ordered.

We liked this specific trim because it basically goes unnoticed. You probably didn’t even see it in the picture from above. They make it in different colors and different “metal” colors, too.

Once we had the trim in hand, we measured the hearth and cut it to the correct length. We ended up with three pieces: two short ones for the sides and one long one for the front. Make sure you cut the trim at a 45-degree angle for an interior corner so the pieces don’t interfere with each other.

Prepping our fireplace hearth for cement tile installation, we taped off the area with painter's tape.

We started by laying out the tile to see what arrangement looked the best and also measured which cuts we would have to make.

We used these spacers in between the tiles.

Then, we removed all the tiles and used a wet tile saw to cut the tile to fit around the edges.

We marked where the middle was so we didn’t forget!

Step 3: Lay Down the Mortar & Install the Tiles

Next, we installed the tile using Thinset Mortar and a square notched trowel to spread the mortar. Apply an even layer to both the surface and the back of the tile.

Remember to place the tile spacers back in between the tile!

We didn’t need to lay anything under the tile since it didn’t need to be waterproof and the surface was already flat. You *may* need something if you’re using the tile in a bathroom or kitchen or on an uneven surface.

Rough idea of how much mortar to put on:

We wiped the excess mortar off the top of the tiles and let them dry!

Step 4: Apply a Sealer

After a few days to dry and set in place, we applied a sealer over the tile.

We followed the manufacturer’s directions using a rag – wipe on, wait 5 minutes and wipe off any excess with a dry rag, then wait 30 minutes and reapply. We then let the sealer dry for a few days.

Finally, we grouted the tile! We used unsanded powder grout and a rubber grout float tool to apply the grout. Work in small sections and wipe off any excess with a wet sponge.

And …. ta da!

I. Am. Obsessed.

It came out perfectly.

Pro-Tips for Installing Cement Tile Flawlessly

So, specifically for CEMENT TILE, here are a few tips we came across to help:

Cement tile is NOT presealed so make sure you seal tile before grouting
Use unsanded grout with a tight joint of 1/16″ – 1/8″
Use white or light-colored grout (dark grout can permanently stain the cement tile .. yikes!)
Find the nearest father-in-law to help (mine’s taken so find your own!) … but seriously he helped SO SO SO much, well, basically did the whole thing — THANK YOU!
