What Is Bluestone
Bluestone is a natural stone used for various outdoor applications, including patios. It’s a type of sedimentary rock, typically a dense sandstone or limestone.
Bluestone gets its name from its predominantly blue-gray color, though it can range from deep blue to greenish-gray.
This stone forms over millions of years as layers of sediment compress under intense pressure.
Quarries in the northeastern United States, particularly New York and Pennsylvania, produce high-quality bluestone.
Different Types of Bluestone

|---|---|---|---|---|
| Thermal Bluestone | Smooth, consistent | Uniform squares/rectangles | Sleek, flat, and even | $10 – $20 |
| Natural Cleft Bluestone | Textured, uneven | Irregular shapes or rectangles | Rough, natural look with variations | $8 – $18 |
| Irregular Bluestone | Natural, textured | Random, irregular shapes | Organic, irregular, free-form | $6 – $15 |
| Cut Bluestone | Smooth or slightly textured | Uniform squares/rectangles | Clean, precise lines | $12 – $25 |
| Tumbled Bluestone | Soft, weathered | Softened edges, uniform shapes | Aged, antique look with softened edges | $15 – $30 |
| Pennsylvania Bluestone | Varies: smooth or textured | Full-range or blue-gray colors | Earth tones (full-range) or blue-gray | $10 – $20 |
Advantages and Drawbacks of Bluestone Patios
Bluestone patios are a popular choice for outdoor spaces due to their natural beauty and durability.
However, like any material, bluestone has its pros and cons. Here’s a breakdown of the advantages and drawbacks of using bluestone for patios:
Advantages of Bluestone Patios
- Durability: Bluestone is a highly durable natural stone that can withstand heavy foot traffic, weather, and wear over time. It is resistant to cracking, chipping, and breaking, making it ideal for patios in various climates.
- Natural Beauty: The unique colors and textures of bluestone create an attractive, natural look for outdoor spaces.
- Versatility: Bluestone comes in various shapes, sizes, and finishes, including thermal, natural cleft, and irregular (flagstone). This makes it suitable for both formal and informal patio designs.
- Slip Resistance: Bluestone’s textured surface, especially in natural cleft or thermal finishes, provides excellent slip resistance, making it safe for areas that may get wet, such as pool decks or patios exposed to rain.
- Weather Resistance: Bluestone is frost-resistant and can handle extreme temperature changes, which prevents it from expanding and contracting, thereby minimizing the risk of cracks in freezing climates.
- Low Maintenance: Bluestone requires relatively low maintenance. Regular sweeping and occasional power washing can keep the patio clean and well-maintained.
Drawbacks of Bluestone Patios
- Cost: Bluestone is more expensive than other patio materials like concrete or gravel. The price of the stone itself, along with professional installation costs, can make it a more costly investment.
- Heat Retention: While generally cool, dark-colored bluestone can retain heat in direct sunlight, potentially making the surface uncomfortable on very hot days.
- Color Fading: Over time, the rich blue-gray tones of bluestone can fade due to exposure to UV rays and weather conditions. Sealing the stone can help protect its color, but regular maintenance may be required to keep the patio looking vibrant.
- Porosity: Bluestone is porous, which can absorb water and other liquids, possibly leading to staining if not properly sealed. This is especially important for patios exposed to spills, like dining areas or near pools.
- Surface Irregularities: Natural cleft bluestone can have an uneven surface, which may not be ideal for furniture placement or accessibility.

Step 2 Mix the Cement Setting Base
- Mix seven parts of stone dust with one part of Portland cement in a wheelbarrow, adding just enough water to hydrate the mixture.
- Ensure the mixture is workable for spreading and stable enough to hold the bluestone slabs.
Step 3 Spread the Cement Mixture
- Apply enough of the cement mixture to cover the area for setting three to four stones.
- Use a pointed trowel to smooth the mixture evenly, ensuring an even 4-inch-thick layer.
Step 4 Lay and Secure the Bluestone
- Set the bluestone slabs onto the cement base and gently tap them into place with a rubber mallet.
- Ensure that each stone sits securely and evenly on the base.
Step 5 Ensure Slope and Level
- Continue laying stones while maintaining a slight slope away from the house for water drainage.
- Use a 4-foot level to check that the patio remains even, adjusting stones as needed.
Different Styles of Bluestone Patios
Bluestone patios can be designed in several distinct styles depending on the cut, layout, and pattern of the stone. These styles allow for a wide range of aesthetics, from formal and structured to rustic and natural.
Here are some of the most popular bluestone patio styles:
1. Random Irregular (Flagstone) Style
This style uses irregularly shaped pieces of bluestone, resulting in a natural, random pattern when laid out. The stones are fit together like a puzzle, with varying sizes and shapes.
- Best For: Rustic, natural, or cottage-style patios.
2. Geometric/Dimensional Style
Bluestone is cut into regular geometric shapes such as squares and rectangles. These stones are arranged in a clean, structured layout, often in patterns like a grid or running bond.
- Best For: Contemporary, modern, or formal landscapes.
3. Herringbone Pattern
In this pattern, rectangular stones are laid at 45-degree angles to form a V-shaped, zigzag pattern. This is a more intricate and visually striking layout.
- Best For: Traditional, formal, or eclectic outdoor spaces.
4. French Pattern (Ashlar Pattern)
This layout combines squares and rectangles of various sizes arranged in a repeated pattern. The stones are laid in an asymmetrical yet structured way.
- Best For: Traditional or European-inspired patios.
5. Circular or Radial Pattern
This style involves arranging the bluestone in concentric circles or radial designs, often around a focal point like a fire pit or a fountain.
- Best For: Central gathering areas or patios with a focal point.
6. Stepping Stone Style
Large, individual bluestone slabs are placed as stepping stones across gravel, grass, or mulch. This style is often used for walkways but can be extended into a patio design.
- Best For: Garden paths, informal patios, or transitional spaces.
7. Mixed Materials Style
This style combines bluestone with other materials, such as brick, gravel, or concrete. Bluestone can be used as the main material with accents or borders of different materials for contrast.
- Best For: Eclectic or custom-designed patios.
Essential Cleaning and Care Tips for Your Bluestone Patio
- Regular Cleaning: Sweep your patio weekly to remove dirt and debris. For routine cleaning, use a mild soap and water solution. Once or twice a year, consider pressure washing on a low setting to deep clean without damaging the stone.
- Stain Management: For tough stains, make a paste using baking soda and water. Apply it to the stain, let it sit briefly, then scrub gently and rinse. To prevent future stains, apply a quality stone sealer every 2-3 years, following the manufacturer’s instructions.
- Seasonal Care: In winter, avoid using de-icing salts, as they can damage the surface. Instead, use sand for traction in icy areas. During other seasons, promptly remove any weeds growing between stones to prevent damage to the patio structure.
- Structural Maintenance: Use felt pads under furniture legs to prevent scratching. If you notice loose or missing mortar between stones, repair it to maintain the patio’s integrity. Consider having a professional inspect your patio every few years to address potential issues early.
By following these maintenance and cleaning tips, you can preserve the natural beauty of your bluestone patio for years to come. Remember, consistent care is key to maintaining your outdoor space’s appeal and longevity.
