After installation, the best time for sealing pavers is when the new pavers are dry and free of any dirt or debris. Most experts recommend waiting for at least 24 to 48 hours before sealing the new pavers after installation.
How long should I wait before sealing my new pavers? Typically 60-90 days. The main reason to wait is so that efflorescence can work its way to the surface and be cleaned off.
So, it's very important to seal your pavers right away. Now we suggest maybe waiting 30 to 60 days, to let the rain really hit it, and wash off the construction debris, let that stone sit and breathe a little bit. But at that 60 day point, its ready to be sealed.
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.
It's best to wait 2-3 months (or even up to one year) before sealing to ensure the efflorescence is completely gone. 2. Make sure the pavers are clean. In addition to the absence of efflorescence, the pavers should be clear of any debris and have no staining.
Keep away from walks and patios for at least 24 hours. If the pavers are for your driveway, wait 48 hours before driving over them, It's also best to wait a full 30 days before you try to clean or seal your pavers. They need weeks to fully cure.
If us- ing polymeric sand, you can install it after the sealer application has properly cured for 24 - 48 hours. If polymeric sand is installed prior to sealing, be sure surface is dry for 24 hours before applying sealer.
To sum up, polymeric sand is a useful adhesive used under brick pavers to hold them in place. It's a long-lasting material that can last for up to 15 years if proper care is taken during the installation process.
You're wondering what happens if you don't seal pavers. Your pavers won't disintegrate if you don't seal them, but they'll likely fade much sooner than if you applied sealant. You'll also need to clean them more often, and the stains won't be as easy to remove.
However, “too much of a good thing” can come into play, and you should be wary of over-applying paver sealer by reapplying too often, which could create a haze.
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.
Customers must also allow at least a 24-48 hours of dry weather after sealer has been applied. 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.
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.
The culprits of blotchy concrete after sealing
When you find yourself staring at discolored concrete that has already been sealed, there are usually three potential sources of blame: The sealer was applied poorly. Not enough sealer was applied. The concrete itself had varying absorption rates.
However, you should NEVER install polymeric sand when it is raining! Rain activates the polymers before the sand is in the joints which will ruin your hardscape by producing a haze and adhering sand grains to the surface of the pavers.
After installation, a hard rain on polymeric sand that has not fully set up could result in polymeric sand all over the top of the pavers. You want to make sure your surface is dry prior to installation and no rain is in the forecast after completing the job for the specified period of time.
If your polymeric sand didn't harden up, it's pretty much guaranteed there's a moisture issue. If the joints remain wet after the installation, they will remain soft until they dry. So getting one initial complete drying "set" is very important to the long-term performance and lifespan of the product.
The Problem With Polymeric Sands & Water Mitigation
Most polymeric sands don't drain water which meant small stones were used to fill the joints between the interlock. For driveways, this solution isn't a big issue but near a pool or patio, people prefer the smooth uniformity of polymeric sand.
Polymeric Sand FAQs
No, new product won't adhere to the old. You have to remove the old polymeric sand and then apply fresh product for the best result. How to replace polymeric sand between pavers? Inspect the pavers to make sure the sand in the crevices is at least 1/8″ below the top of the pavers.
Regular sand for paving is prone to erosion, damage from weeds and can make your pavers hard to wash without risking the loss of any jointing sand between the stones. Using polymeric sand, however, prevents weeds from taking root and holds pavers firmly in place thanks to the durability of its seal.
Enhanced aesthetic: The paver sealer enhances the curb appeal of your properties and provides perfect finish to the paved areas and at the same time stabilizes the joint sand by locking it in place. It protects the pavement against harmful UV rays and prevents fading.
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.
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.
