Concrete and pavers are tough, but water and time win if you ignore them. A little maintenance keeps them looking sharp for decades.
Seal it
Sealing concrete and pavers blocks water, oil and salt from soaking in. That's what prevents staining, surface flaking, and the freeze-thaw cracking that's brutal in tri-state winters. Most surfaces want a fresh seal every 2–3 years.
Weeds in paver joints
- Pull or kill existing weeds first.
- Re-sand the joints with polymeric sand — it hardens to lock pavers together and choke out weeds.
- Seal over the top to hold the sand in place.
That white, chalky haze
It's called efflorescence — mineral salts pushed to the surface by moisture. It's normal on new concrete and pavers and can be cleaned off with the right product. It's a moisture sign, not a defect.
