Ultimately, you can expect to enjoy between three and five years of protection from a high-quality sealer. With that said, a big part of answering the question, “How long does paver sealer last?” will depend on environmental factors such as weather and foot traffic.
The basic rule of thumb is every 3-5 years. For film-forming sealants, you will be able to notice when the physical barrier is showing signs of wear. For non-film-forming sealants, you will begin to see a significant color change of pavers during a rain when the sealant is wearing thin.
After 18-24 months, your paving will be ready for a fresh top-up of sealer. It's important to use the same product to get the same results, but the process is much the same. If you have opted for Black Limestone, the time limit is a little different - make sure you have a read up on the material here.
It is on the surface 'indefinitely', though it can get worn off with vehicular or foot traffic. Even when the sealer coating has worn an element of the sealer will still remain as it will have soaked in to the concrete, which will continue to help reduce dusting.
Paver sealant is a great tool to keep paver driveways, patios, walkways, and pool decks, in mint condition, but it's not always necessary. While it's not a must-have, pavers that aren't sealed typically grow weeds in the cracks, lose color over time, and can even have shifting caused by a lack of joint sand.
All pavers are susceptible to weather elements and, over time, they can fade, stain, grow mildew and become dirty looking. The sealer can help prevent the stains and other signs of weather damage from occurring and when washed, won't allow residual effects to settle into the pavers.
Acrylics. Acrylic paver sealers, either solvent- or water-based, offer the most comprehensive ultraviolet (UV) resistance. Acrylic sealants can be breathable, depending on their solid content.
Most contractors and manufacturers recommend sealing pavers for the many benefits. Both concrete and brick pavers are porous materials that can change quality and appearance when they absorb liquids.
Traditionally, concrete paver manufacturers have recommended waiting at least 90 days after polymeric sand installation to apply a protective sealant to a paver surface. Nowadays, a 30 day delay is sufficient to allow the evaporation of any remaining natural efflorescence contained in the pavers.
The answer depends on the surface's square footage. For large surfaces such as commercial floors, a sprayer is faster and way more efficient. Finally, for small surfaces, such as garages or any other exterior surface, a paint roller or any other type of roller will do the trick. Rolling is a less expensive process.
Fall or spring is a great time of the year to seal pavers. Cooler weather allows the sealer to penetrate into the pavers unhindered. Pavers will have an adequate amount of protection for when it's time to seal again. Make sure to keep leaves and other debris off the pavers while they are drying to avoid blemishes.
One of the best paver sealers is the Siloxa-Tek 8500. It is a penetrating concrete sealer designed to treat a variety of applications with an emphasis on hydrophobicity and reduction of water uptake. It dries completely clear with a natural finish that will not change the look or appearance of the susbtrate.
How Much Does It Cost to Clean and Reseal Pavers per Square Foot? In total, you should expect to pay around $2 per square foot to clean and seal pavers. The price may vary between $1 and $3 per square foot, depending on the sealant and method of cleaning.
You pressure clean the pavers, re-sand the paver joints and then apply two coats of your favorite paver sealer and the job was complete.
If the sealer is not cured correctly, water can cause white marks or stains on your pavers and can even be trapped beneath the layer of sealer. It is very important not to walk or drive on sealed pavers at least 24-48 hours after application. A protective sealer enhances the natural color and beauty of your pavers.
If a white haze appears on sealed pavers, it is less likely that the white spots are efflorescence but rather, water condensation collecting underneath the sealer. Removal is still possible, but a chemical solution is required. If your sealer is oil-based, the fix is to re-emulsify the sealer with Xylene.
If it still happens to rain unexpectedly, don't apply more sealant over the ruined coat because this will make it even harder to fix it. Instead, use a solvent specifically for the type of sealant that you are using. Solvents can liquify the ruined coat of the sealant and will give you a fresh start.

Some paver sealers can provide a glossy sheen or "wet" look which many homeowners like. Not only do these brick paver sealing products enhance the natural beauty of the pavers with a shiny gloss look, but they also waterproof and protect against the elements. Paver sealer can also keep your pavers cleaner.
Once applied, sealers create a chemical reaction and the outside temperature decides how fast that reaction occurs—or if it happens at all. Most manufacturers recommend 50 to 90 degrees as the ideal temperature range for applying concrete sealer.
Pavers should be resealed every 3 to 4 years on average. You will know when your pavers need to be resealed because water will stop beading on the surface and the sheen will diminish. In addition, you may notice weeds starting to grow in between joints and the pavers may start to lose their color.
Sealer Cost: Everything You Need to Know. Sealing concrete sealing or “seal coating” costs between $1.20 – $1.75 per square foot. Factors that determine cost include project fees, quality of concrete, stamped vs regular, or if you opt to do it yourself.
