Paver Sealing 101: When, Why & How Often

Pavers are everywhere in Southwest Florida — driveways, pool decks, lanais — and most of them are quietly deteriorating for one preventable reason: they were never sealed, or the seal wore off years ago.

What Sealing Actually Does

Concrete pavers are porous. Unsealed, they drink in whatever lands on them: irrigation rust, oil, tannin stains from leaves, and the moisture that feeds black mold and green algae. A quality sealer closes those pores, locks the joint sand in place, and adds UV protection that slows color fading.

The Telltale Signs It's Time

• Water soaks in flat instead of beading on the surface
• Colors look chalky compared to the pavers under a doormat or planter
• Joint sand washes out after heavy rain, leaving gaps and wobbly pavers
• Black or green growth returns within weeks of every cleaning
• Weeds and ants colonize the joints

The Right Process (Order Matters)

Good sealing is a system: deep-clean first (pressure wash plus treatment for mold and rust), let everything dry fully, re-sand the joints with fresh sand, sweep clean, then apply sealer in the right conditions — dry pavers, no rain in the forecast, and moderate temperatures. Sealing over trapped moisture is what causes the cloudy white haze you see on bad seal jobs.

How Often in Florida?

Every 2–4 years for driveways and pool decks, on the shorter end for full-sun and high-traffic areas. The good news: recoats over a maintained surface are faster and cheaper than a first-time restoration.

Finish Options

Wet-look enhances color and gives a rich, glossy finish; matte or natural preserves the original look while still protecting; and pool decks should always get an anti-slip additive — ask for it by name.
