Exterior stone surfaces—like patios, walkways, facades, retaining walls, and garden features—add timeless elegance and durability to your property. But over time, exposure to sun, rain, wind, and foot traffic can wear down stone surfaces, leaving them dull, stained, or even structurally compromised.
Restoring exterior stone not only brings back its natural beauty but also protects it from future damage, prolonging its lifespan. At A&D Floor Restoration, we specialize in professional exterior stone restoration, combining cleaning, repair, and protective treatments for stunning, long-lasting results.
Step 1: Evaluate the Stone Condition
Before any restoration begins, a thorough inspection is essential. Exterior stone can suffer from:
-
Stains from dirt, moss, algae, or bird droppings
-
Surface erosion or pitting from weathering
-
Cracks or loose joints caused by settling or freeze-thaw cycles
-
Efflorescence, a white powdery residue caused by water seeping through porous stone
Understanding the type and severity of damage helps determine the most effective restoration methods. A&D Floor Restoration technicians assess stone type, location, and exposure to create a custom restoration plan.
Step 2: Deep Cleaning and Surface Preparation
The next step is professional cleaning to remove dirt, stains, algae, and other contaminants. Exterior stone often requires specialized treatments:
-
Pressure washing at controlled levels to prevent damage
-
Mild chemical cleaners safe for natural stone
-
Algae and moss removal to stop recurring growth
Surface preparation also includes repairing cracks, replacing missing mortar, and stabilizing loose pieces, ensuring the stone is ready for the restoration and protection process.
Step 3: Repairing and Polishing
For polished or honed exterior stone, restoration may include smoothing uneven surfaces, removing minor scratches, and refinishing the stone’s texture. This step is critical for walkways and patios to ensure safety as well as aesthetic appeal.
For structural elements like walls or columns, restoration focuses on stabilizing and repairing cracks or chips, preserving both appearance and integrity. This ensures that your stone can withstand the elements for years to come.
Step 4: Sealing and Protective Treatments
Once cleaned and repaired, applying a high-quality stone sealer or protective coating is essential. Sealing exterior stone helps:
-
Repel water and prevent moisture damage
-
Protect against staining from leaves, dirt, and debris
-
Reduce growth of moss and algae
-
Maintain color and natural appearance
At A&D Floor Restoration, we also offer MORE® AntiEtch® and other advanced coatings for surfaces that are prone to chemical or acid exposure, providing long-lasting protection without altering the stone’s natural look.
Step 5: Ongoing Maintenance
Exterior stone requires routine care to preserve its restored beauty:
-
Sweep or hose down surfaces regularly
-
Remove organic debris promptly to prevent staining
-
Schedule periodic professional cleaning and resealing as needed
Consistent maintenance, combined with professional restoration, keeps exterior stone looking vibrant, extends its lifespan, and protects your investment.
