Planning Your Stone Veneer Project
Choosing the Right Stone Veneer Type
When selecting stone veneer for your home improvement projects, you’ll need to choose between manufactured and natural options. Manufactured stone veneer, also known as cultured stone, offers consistent coloring and patterns at a lower cost point. It’s typically lighter and easier to install, making it popular for DIY installations. However, the patterns may repeat more noticeably than natural stone.
Natural stone veneer, while more expensive, provides authentic variations in color and texture that can’t be replicated. Each piece is unique, creating a truly distinctive appearance. Though heavier and sometimes more challenging to work with, natural stone often offers superior durability and weather resistance.
Common styles include ledgestone for a horizontal, stacked look; fieldstone for a more rustic, random pattern; and castle stone for a formal, organized appearance. Consider your home’s architectural style and existing materials when making your selection. Remember that proper cultured stone maintenance is essential for both types to ensure longevity and preserve their appearance over time.

Surface Preparation Steps
Installing the Moisture Barrier
A properly installed moisture barrier is crucial for protecting your home from water damage and ensuring the longevity of your stone veneer installation. Begin by covering the entire wall surface with two layers of water-resistant building paper, starting from the bottom and working your way up. Each layer should overlap by at least 2 inches horizontally and 6 inches vertically, creating a shingle effect that directs water downward.
Next, install expanded metal lath over the building paper. The lath should be galvanized and weigh at least 2.5 pounds per square yard. Secure it using galvanized roofing nails or staples every 6 inches along the studs. Ensure the lath’s diamond pattern is installed pointing upward to create proper mortar adhesion.
Pay special attention to corners and openings. At exterior corners, wrap the moisture barrier and lath around the corner by at least 16 inches. For windows and doors, install proper flashing before the moisture barrier, and create a drip edge at the bottom to prevent water from seeping behind the veneer.
Remember to leave a weep screed at the bottom of the wall where it meets the foundation. This allows any trapped moisture to escape and prevents water damage to your home’s structure. The screed should be positioned at least 4 inches above grade for siding applications and 2 inches above a paved surface.
Metal Lath Installation
The success of your stone veneer installation heavily depends on proper metal lath installation. Begin by covering your water-resistant barrier with a layer of asphalt-saturated felt paper, overlapping each piece by at least 2 inches to ensure proper drainage. Install the paper from bottom to top to create proper water flow.
Next, install your galvanized diamond mesh metal lath. The lath should be self-furring with dimples that create a 1/4-inch space between the lath and the wall surface. Start at the bottom of your wall and work upward, overlapping pieces by at least 1 inch on horizontal seams and 2 inches on vertical seams.
Secure the lath using galvanized roofing nails or staples every 6 inches along studs and at overlapping seams. The lath should feel tight against the wall with no loose or sagging areas. Ensure the rough side of the lath faces outward – you should feel resistance when running your hand upward on the surface.
Around corners, bend the lath to create clean edges rather than cutting it. For inside corners, overlap the pieces by at least 3 inches. For outside corners, wrap the lath around the corner and extend it at least 16 inches in both directions.
After installation, inspect the entire surface to ensure all fasteners are secure and there are no gaps or loose sections that could compromise the scratch coat adhesion.
Installation Process
Applying the Scratch Coat
Begin by mixing your scratch coat mortar according to manufacturer specifications, typically combining portland cement, sand, and water until you achieve a consistent, workable consistency similar to peanut butter. Use a power mixer for larger batches to ensure thorough blending and prevent lumps.
Apply the scratch coat to your prepared surface using a steel trowel, maintaining a thickness of approximately ½ inch. Work in manageable sections of about 10 square feet at a time to prevent premature drying. Press the mortar firmly against the metal lath, ensuring complete coverage and good adhesion.
Once you’ve applied the mortar, use a notched trowel or scratch rake to create horizontal grooves across the entire surface. These grooves should be approximately ¼ inch deep and spaced about 1 inch apart. This scoring pattern is crucial as it creates a strong mechanical bond for the stone veneer.
Allow the scratch coat to cure for at least 24 hours before proceeding with stone installation. During hot or windy conditions, mist the surface periodically with water to prevent rapid drying, which can lead to cracking. The scratch coat should feel firm and stable when cured properly.
Keep the surface clean and free from debris during the curing process. If you notice any cracks or weak spots, repair them before moving forward with stone installation.
Setting the Stone Veneer
Begin laying your stone veneer from the bottom corners and work your way up, similar to natural stone wall installation. Apply mortar to the back of each stone using a trowel, creating a layer approximately 1/2 inch thick. Press the stone firmly against the prepared surface, wiggling it slightly to ensure proper adhesion. Maintain consistent joint spacing between stones, typically 3/8 to 1/2 inch, using plastic spacers if needed.
Work in small sections to prevent the mortar from drying before stones are set. Alternate between different sizes and colors of stones to create a natural, random pattern. Avoid creating obvious vertical lines by staggering the joints. As you progress, periodically step back to assess the overall appearance and make adjustments as needed.
For corners, use corner pieces specifically designed for your veneer system, installing these first before filling in the flat sections. Cut stones as needed using a wet saw equipped with a diamond blade. When cutting is required, make sure to vary the cut edges so they don’t align noticeably in the pattern.
Keep the stones clean as you work by wiping away any excess mortar with a damp sponge before it hardens. If mortar does get on the face of the stones, let it dry slightly before brushing it off with a soft-bristled brush. This prevents smearing and staining.
Once all stones are in place, allow the mortar to set for 24 hours before proceeding with grouting. During this time, protect the work area from direct sunlight, wind, and rain, as these conditions can affect proper curing. If working outdoors, consider covering the area with plastic sheeting.
Pay special attention to areas around windows, doors, and other obstacles. Use appropriate flashing and maintain proper clearances to prevent water infiltration. For stones that need to be shaped around obstacles, make paper templates first to ensure accurate cuts and minimize waste.
Remember to check your work periodically with a level to maintain proper alignment, especially on vertical surfaces. This attention to detail during installation will ensure a professional-looking finish that will last for years to come.
Grouting and Finishing
After allowing the mortar to cure for at least 24 hours, it’s time to apply the grout. Mix the grout according to manufacturer specifications, aiming for a consistency similar to peanut butter. Using a grout bag, carefully fill all joints between stones, working from top to bottom. Keep the grout slightly recessed from the stone face to create an authentic, dimensional appearance.
Once the grout begins to set (typically 30-60 minutes), use a jointing tool to smooth and compact it. This creates clean, professional-looking joints while ensuring proper adhesion. Remove any excess grout from stone surfaces immediately using a damp sponge to prevent staining.
Allow the grout to cure for 48-72 hours before applying a quality stone sealer. Choose a penetrating sealer designed specifically for stone veneer to protect against moisture and staining while maintaining the stone’s natural appearance. Apply the sealer using a pump sprayer or brush, following the manufacturer’s instructions for coverage and number of coats.
For optimal results, apply two thin coats of sealer rather than one heavy coat. Allow the first coat to dry completely before applying the second. The sealed surface should be protected from rain and moisture for at least 24 hours after application. Regular maintenance, including annual cleaning and resealing every 2-3 years, will help preserve your stone veneer’s beauty and durability.
Maintenance and Care
Proper maintenance of your DIY stone veneer installation ensures its longevity and preserves its aesthetic appeal. Regular cleaning should be performed using a soft-bristled brush and mild soap solution, avoiding harsh chemicals or acidic cleaners that can damage the stone surface. For routine maintenance, simply hosing down the veneer with water helps remove dust and prevent dirt buildup.
Inspect your stone veneer annually for any signs of damage, loose pieces, or deteriorating mortar joints. Address these issues promptly to prevent water infiltration and more extensive damage. If you notice any cracks or gaps in the mortar, repair them using appropriate mortar patching compound matched to your original installation color.
Sealing your stone veneer every 2-3 years provides additional protection against moisture and staining. Choose a penetrating sealer specifically designed for stone surfaces, and apply it according to manufacturer instructions. Before sealing, ensure the surface is clean and completely dry.
In winter climates, avoid using de-icing salts near stone veneer as they can cause deterioration. Instead, use sand or cat litter for traction on icy surfaces. If efflorescence (white, powdery deposits) appears on your veneer, remove it using a dry brush. For stubborn deposits, consult a stone care professional for appropriate cleaning solutions.
Keep climbing plants and vegetation trimmed away from the veneer surface to prevent moisture retention and potential damage from root systems. Regular gutter maintenance also helps prevent water damage to your stone veneer installation by directing water away from the surface.
Installing stone veneer as a DIY project is an achievable goal that can dramatically boost your property value while transforming your home’s appearance.
