Fasteners: Screws or nails are needed to attach the metal lath to the wall.

3. What Are The Different Types Of Rocks Suitable For A Fireplace Wall?

The type of rock you choose will significantly impact the overall look and feel of your fireplace wall. Each type of rock has unique characteristics that can complement different architectural styles.

Fieldstone: This is a classic choice for rock fireplace walls, offering a rustic and natural look. Fieldstone typically consists of a variety of shapes, sizes, and colors, creating a visually interesting and textured surface. It’s commonly found in the Northeast and Midwest regions of the United States.
River Rock: Smooth and rounded, river rocks bring a sense of tranquility and elegance to a fireplace wall. They are typically smaller in size and come in a range of colors, from light tan to dark gray. River rock is often used in contemporary or minimalist designs.
Ledgestone: This type of stone is characterized by its long, thin, and rectangular shape. Ledgestone is easy to install and creates a clean, modern look. It’s available in a variety of colors and textures, making it a versatile choice for any home.

4. How Do You Prepare The Wall Surface Before Installation?

Proper preparation of the wall surface is crucial for ensuring the longevity and stability of your rock fireplace wall. This step involves creating a clean, solid surface for the mortar to adhere to.

Clean the Wall: Remove any dust, dirt, grease, or loose paint from the wall surface. A pressure washer or a wire brush can be used for this purpose.
Install Metal Lath: Attach metal lath to the wall using screws or nails. The metal lath provides a surface for the mortar to grip onto, especially if you’re working with a framed wall. Overlap the edges of the metal lath by at least 2 inches.
Apply a Scratch Coat: Mix a batch of mortar and apply a thin layer, known as a scratch coat, over the metal lath. Use a notched trowel to create grooves in the scratch coat, which will provide additional grip for the next layer of mortar. Allow the scratch coat to cure for at least 24 hours.

5. What Is The Best Mortar Mixing Technique For Rock Fireplace Walls?

Mixing the mortar correctly is essential for creating a strong and durable bond between the stones. The ideal mortar consistency should be similar to that of thick peanut butter.

Use a Mortar Mixer: A mortar mixer will ensure that the ingredients are thoroughly combined.
Add Water Gradually: Add water to the dry mortar mix in small increments, mixing continuously until you achieve the desired consistency.
Avoid Overwatering: Adding too much water will weaken the mortar and make it difficult to work with.
Mix in Batches: Mix only as much mortar as you can use within an hour or two, as it will start to harden over time.

According to experts at Arizona State University’s School of Earth and Space Exploration, the quality of mortar significantly impacts the longevity of stone structures.

6. How To Properly Apply Mortar And Set The Rocks?

Applying the mortar and setting the rocks is where your rock fireplace wall starts to take shape. Patience and attention to detail are key in this step.

Apply Mortar to the Stone: Using a trowel, apply a generous layer of mortar to the back of each stone. Make sure to cover the entire surface that will be in contact with the wall.
Set the Stone: Press the stone firmly against the wall, wiggling it slightly to ensure good contact with the mortar.
Maintain Consistent Spacing: Use shims or spacers to maintain consistent spacing between the stones.
Work from the Bottom Up: Start at the bottom of the wall and work your way up, allowing the mortar to set slightly before adding the next row of stones.
Remove Excess Mortar: Use a small trowel or putty knife to remove any excess mortar that squeezes out between the stones.

7. How Do You Achieve Different Aesthetic Styles With Mortar Techniques?

The way you apply and finish the mortar can dramatically change the appearance of your rock fireplace wall. Experiment with different techniques to achieve the desired aesthetic.

Flush Mortar Joint: This technique involves filling the joints between the stones completely flush with the surface. It creates a clean and modern look.
Recessed Mortar Joint: In this technique, the mortar is recessed slightly below the surface of the stones, creating a more rustic and textured appearance.
Over-Grouted Stone Fireplaces: Over-grouting involves applying more mortar than usual, allowing it to spill onto the front of the stones. This creates a softer, cottage-like look, as seen in many inspiration photos.
Tuckpointing: This is a decorative technique where a thin line of colored mortar is applied to the surface of the joint, creating a visually striking effect.

As demonstrated at rockscapes.net, the possibilities are endless.

8. How To Clean And Finish The Rock Fireplace Wall?

Once the mortar has fully cured, it’s time to clean and finish your rock fireplace wall. This step will enhance the natural beauty of the stones and ensure a long-lasting finish.

Remove Mortar Haze: Use a scrubby sponge and water to wipe off any mortar haze that may have accumulated on the surface of the stones. You can add some coarse salt or sugar to the water for extra cleaning power.
Clean the Stones: Use a mild detergent and water to clean the stones. A soft-bristled brush can be used to remove any stubborn dirt or stains.
Apply a Stone Sealer: Applying a stone sealer will protect the stones from moisture and staining. Choose a sealer that is specifically designed for the type of stone you have used.
