The Difference Between Interlock Sealing and Sanding – Which Do You Need?

Many homeowners wonder whether their interlock needs sealing or sanding—or both! Here’s what each service does and when to consider it:

Interlock Sealing

✔ Purpose: Protects pavers from stains, UV fading, and water damage.
✔ Best for: Enhancing color, adding durability, and preventing erosion.
✔ When to do it: Every 2-3 years for long-lasting protection.

Interlock Sanding

✔ Purpose: Fills the gaps between pavers to prevent shifting and weed growth.
✔ Best for: Keeping pavers stable and maintaining structural integrity.
✔ When to do it: When sand has eroded, causing wobbly or loose pavers.

💡 Pro Tip: For best results, sanding should be done before sealing to lock everything in place.
