Fireplace Stone Installation: The Part I Have Been Waiting For

Last time, we wrapped up the fireplace mantle and nearly all of the drywall. Today, we are picking up right where we left off, finishing the last round of sanding and texture, then heading out to pick out the stone that is finally going to go over the top of this mantle. Because honestly, what is a fireplace without stone? This post walks through texturizing the walls, choosing the stone, and the full installation process, including the moments it went smoother than expected and the moments it genuinely tested my patience.

Finishing the Texture

Before any of the fun stuff could happen, I had to finish texturizing the drywall to match the existing orange peel texture already on the rest of my walls. Since I knew this stage would get incredibly dusty, I put on a respirator mask and my Aleah safety glasses before getting started. Matching existing texture is also a nice safety net for anyone who, like me, is not a professional drywaller, since a little texture disguises a lot of small imperfections that would otherwise stand out under flat paint.

I genuinely underestimated how much texturizer I would need. I started with two large cans, thinking that would easily cover both sides of the fireplace, and burned through the first can almost immediately. By the end, I realized I needed roughly three bottles per side, which meant a mid-project supply run before I could keep going. If there is a running theme on this entire build, it is underestimating material quantities, first with joint compound, now with texture spray.

Choosing the Stone

With texturing finally behind me, it was time for the genuinely exciting part: picking out stone for the fireplace stone installation. I could easily spend hours wandering a stone and tile store, but I stayed focused since I already had a rough idea of what I wanted. I ended up choosing a stone that matches my floor tile and the overall color palette already running through the rest of my house. 

Each stone panel comes mounted on a heavy wire mesh backer, and they are genuinely heavy, roughly four and a half square feet of coverage per box, with only two panels included per box because of that weight. I knew going in that I would need help unloading them at home and likely help getting some of the heavier pieces up onto the wall as well.

Starting the Installation

Before making the first cut or placing the first piece, I marked level lines on both sides of the mantle to keep the stone centered and consistent, leaving a bit of visible drywall on either edge as a border. Since this stone is mounted on steel mesh, it cannot go through a standard tile saw without popping that backing off first for any piece that needs trimming.

Popping the mesh backing off with a stiff putty knife meant working against strong construction adhesive, and a couple of pieces tried to spring back at my face while I worked them loose. That is exactly why I kept my Aleah safety glasses on for this entire stage. These are ANSI-certified, tactical-grade glasses with both top and side protection, and having that side coverage mattered more than I expected once pieces started popping unpredictably.

One thing that genuinely surprised me: unlike tile, stone is not meant to sit perfectly flush and smooth. The natural texture and variation in thickness from piece to piece is expected and even desirable, which took a little bit of pressure off compared to a project where every seam needs to line up with tile-level precision.

Before mixing and applying mortar, I put on my Aleah nitrile gloves. Mortar dries hands out fast and gets messy quickly, so having a thick, reliable glove on hand made the back buttering process, spreading mortar directly onto the back of each stone piece, much more manageable.

Getting the First Pieces Up

The first piece I installed set the tone for the rest of the wall, and once it held in place, the momentum genuinely picked up. I worked to place as many full, uncut pieces as possible first, saving all of the trickier custom cuts for one focused session at the end rather than constantly switching between the tile saw and the wall.

Surprisingly, this process felt easier than laying tile. There was less pressure to achieve perfect alignment, and the natural irregularity of stone meant small variations actually worked in my favor instead of standing out as mistakes. I started from one corner to keep the outside edge clean and consistent, planning to push any unavoidable irregularities toward the center of the wall where they would be less noticeable.

For the pieces near the top of the installed section, where there was nothing underneath to brace the weight of the stone while the mortar cured, I added a few strategically placed support screws. This let that section dry fully overnight with real support behind it, meaning I could continue building the next day upward with confidence that the lower section would not shift or sag under the weight of everything above it.

Cutting the Remaining Pieces

The next morning, with warmer weather finally on my side, I moved outside to handle the remaining cuts on my tile saw. Cutting stone this thick meant leaving the water guard in place despite it being a little inconvenient, since removing it would have sent water spraying everywhere. A few of the thicker pieces required a bit of extra care and slower cutting, but the saw handled them without any real issues.

I also went back and tightened the support screws from the night before a bit further, mostly for extra long-term stability. Since those screws get sunk in deep enough to disappear under grout later, there was no real downside to adding that extra reinforcement, even if it turns out not to be strictly necessary.

Finishing the Wall

With my husband's help lifting some of the larger, heavier stone sections into place, mostly because they truly are too heavy and awkward to maneuver solo, we finished covering the wall by the end of the day. A couple of final screws helped snug the topmost piece up against the ceiling for a clean, tight fit.

Seeing the stone actually installed, even before grouting, made the entire project feel real in a way it had not felt before. After weeks of framing, drywall struggles, and crown molding headaches, this was the first moment the fireplace genuinely started looking like the finished vision I had been carrying around in my head for months.

What Comes Next

With the stone installation complete, the remaining steps are grouting the joints, painting both the mantle and the surrounding walls, and installing the built-in cabinets and shelving on either side, along with the final lighting. We are firmly in the beautifying stage of this build now, which, after everything this project has put me through, feels like a genuine reward.

There is a lot more detail in the actual footage than fits neatly into writing, including the full process of popping mesh backing off stone panels and the moment the first section went up on the wall. If you want to see it all as it happened, watch the complete episode on my YouTube channel, Aleah DIY. It covers everything in this post plus the parts that are much easier to appreciate when you can actually see them unfold.

Frequently Asked Questions

Why does stone veneer need to have its wire mesh backing removed before cutting? 

Most tile saws are not designed to cut through steel mesh, and forcing it through can damage the blade or the saw itself. Removing the mesh backing with a stiff putty knife on any piece that needs a custom cut allows it to go through a standard wet saw safely.

Is it normal for stone veneer to look uneven or textured compared to tile? 

Yes. Unlike tile, which is meant to sit flush and consistent, natural stone veneer is expected to have variation in thickness and texture from piece to piece. That irregularity is part of the appearance and should not be treated as a flaw the way it would be with tile.

Why use support screws when installing heavy stone veneer on a vertical wall? 

Stone veneer is significantly heavier than standard tile, and without something bracing it while the mortar cures, upper sections can shift or sag under their own weight. Strategically placed screws provide temporary support until the mortar fully sets, and they disappear under grout once the project is finished.

What gloves are best for working with mortar and stone installation? 

A thick, durable glove that resists both drying agents in mortar and general wear is ideal. Standard Aleah nitrile gloves work well for this kind of messy, hands-on installation work, since mortar dries skin out quickly with prolonged contact.

Why wear safety glasses specifically when removing wire mesh backing from stone tiles? 

Prying mesh backing off with a putty knife can cause the material to spring back unexpectedly toward your face, especially when working against strong construction adhesive. Certified glasses with side protection, like Aleah safety glasses, guard against that kind of unpredictable movement, not just debris flying straight ahead.
