Paver Sealer:
Types, Costs &
When to Seal

A paver sealer is a liquid you spray or roll onto concrete or clay pavers to slow down water, oil and UV damage, lock the joint sand in place and, if you want it, darken the color to a wet look. Pick the wrong one and you get a cloudy white haze, a slick pool deck, or a film that flakes off after two summers. We manufacture polyurea and polyaspartic coatings, not paver sealers, so this is the plain version: what each sealer chemistry really does, what it costs in 2026, how to tell whether your pavers are ready, and the few cases where a coating beats a sealer.

Which paver sealer should you buy?

Most bad paver jobs come from picking a sealer for its label photo instead of for the job. Answer five questions and the selector narrows it to one chemistry, with the coverage and service life the manufacturers publish.

When to seal new pavers and when to wait

Efflorescence is the white, chalky bloom that shows up on almost every new concrete paver. It is salts carried to the surface by water, not a defect, and it is the number one reason sealed pavers end up with trapped white haze. Cambridge Pavers says efflorescence typically stops in about 18 to 24 months, and ICPI notes it can be at its worst within 60 days of installation. The pavers have to be completely dry and free of efflorescence before any sealer goes on. ICPI also asks for at least 24 hours with no moisture or surface dampness before application.

How to seal pavers without the usual mistakes

1. Fix the base before you seal

   Sealer will not hold up sunken or rocking pavers. Lift and re-bed low spots and replace cracked units first. Sealing locks in whatever is there.

2. Clean, then clean the efflorescence

   ICPI describes professional pressure washing at 1,000–4,000 psi and 2–6 gallons per minute, with a fan tip held far enough back not to chew up the paver face or blow out the joints. Efflorescence cleaners go on at low pressure, 30–100 psi, per the same spec. Rinse thoroughly; cleaner residue under sealer causes adhesion and haze problems.

3. Re-sand the joints

   Sweep dry joint sand back in until the joints are full to just below the chamfer. ICPI notes that joint sand with less than 5% fines passing the No. 200 sieve lets stabilizing sealer penetrate better, so do not use dusty play sand.

4. Let it dry, really dry

   At least 24 hours with no rain, dew or irrigation (ICPI). In humid weather or shade we give it longer. Lay a square of plastic down for a few hours; if it fogs underneath, wait.

5. Test a patch

   Seal a 2 × 2 ft area in a corner and look at it the next day for color, sheen and haze. This is where you find out the wet look is darker than you wanted, before it is on 600 sq ft.

6. Apply thin, even coats

   Low-pressure pump sprayer with a fan tip, back-rolled with a 3/8 in. nap roller to push out puddles. Two thin coats always beat one heavy coat; puddles are what turn white. Stay in the data-sheet window, typically 50–90°F surface temperature, and out of direct midday sun on dark pavers.

7. Keep traffic off

   Foot traffic after 24 hours is typical; MasonrySaver asks for 7 days before hot tire traffic and Eagle's solvent sealer allows vehicles after 48 hours. Turn off sprinklers for at least a day.

Paver sealer vs. a polyurea or polyaspartic coating

We get asked a lot whether our polyurea or polyaspartic coatings can go over pavers. Our honest answer is usually no. Interlocking pavers are designed to flex a little and drain through the joints. A continuous film coating bridges those joints, cracks along the joint lines as the pavers move, and can trap water in the bedding sand. For pavers, a breathable paver sealer is the right tool.

Where coatings do make sense is on the poured concrete around your pavers, or when you are deciding between pavers and a slab in the first place:

• A cracked or stained concrete patio next to the pavers: compare options in our patio coating guide, or just seal it with the right concrete sealer.
• Concrete driveways that see road salt: see concrete driveway sealer options.
• Hot or worn concrete pool decks: a textured system such as ArmorDeck or a full pool deck resurfacing outlasts a sealer.
• Garages and covered patios on slab: an aliphatic polyaspartic resists UV yellowing and hot tires far better than any paver sealer.
