Key takeaways
- Joint sand locks pavers together and keeps weeds out.
- Sealing protects color and helps hold sand.
- Moss and stains need cleaning, not just rinsing.
- Sunken areas point to base or drainage problems.
Joint sand
Polymeric sand hardens slightly after activation, locking pavers and resisting weeds and ants. Over time it washes out and needs refilling, often every few years.
Cleaning and sealing
Pressure cleaning removes dirt, moss and stains, and sealing protects color and reduces future staining. Choose a sealer suited to the use, such as slip-resistant types for pool decks.
Repairing movement
If pavers have sunk or shifted, lift them, repair the base underneath and re-lay them. Simply adding sand rarely fixes the problem.

Quick answers
How often should pavers be sealed?
Many owners reseal every two to four years, depending on sun, traffic and the product.
Can I pressure wash pavers myself?
Yes, but too much pressure can wash out the joint sand and damage the surface. A professional uses lower pressure and re-sands afterward.
