How to Care for Your Bluestone Patio

A bluestone patio is a timeless, durable investment. With a little routine care, it will look great for decades.

1. Keep It Clean (But Be Gentle)

Regularly sweep away leaves, dirt, and debris to prevent staining and organic buildup. For general cleaning, use water and a stiff broom. If needed, a mild, pH-neutral soap works well—avoid harsh cleaners or acids.

2. Watch for Stains Early

Bluestone is porous. Oil, grease, or fallen leaves can leave marks if left too long. Clean spills promptly, and remove wet leaves or mulch after storms to avoid dark staining.

3. Use the Right De-Icing Products

In winter, avoid rock salt or calcium chloride. These can cause surface flaking over time. If traction is needed, use sand or a stone-safe ice melt labeled for natural stone.

4. Be Smart with Snow Removal

Plastic shovels are best. If using a metal shovel or snow blower, keep the blade slightly raised to avoid scratching or chipping the stone edges.

5. Manage Moss and Algae

Shaded or damp areas may develop moss or algae. A light scrub and improved drainage usually solve the issue. Avoid pressure washing at high settings—it can damage the stone and joint material.

6. Maintain the Joints

Polymeric sand or mortar joints may need occasional touch-ups. Keeping joints intact helps prevent shifting, weed growth, and water infiltration.

7. Consider Sealing (Optional)

Sealing is not required, but a breathable stone sealer can help reduce staining and enhance color. If you choose to seal, reapply according to manufacturer recommendations and avoid creating a glossy surface.

8. Let It Weather Naturally

Bluestone develops character over time. Slight color variation and soft wear are part of its appeal and do not affect performance.
