Most experts recommend waiting for at least 24 to 48 hours before sealing the new pavers after installation. This gives the pavers time to settle and ensures that they're completely dry before being sealed. If you live in an area with a lot of rain or snow, it's best to wait even longer to seal the brick pavers.
A minimum of 24 hours drying time is required prior to allowing foot traffic and 48 hours for vehicular traffic on the paver surface. Dampening: Apply a gentle fine mist to the filled joints, flooding the faces of the pavers and allowing the water to run into the joints. Do not flood the sand onto paver surfaces.
You can drive and park on your new driveway pavers as soon as the pavers have been grouted with sand. That is the final step in the process, if you don't want sealer. If you do want sealer, you should wait a full 24 hours for the sealant to cure.
Yes, pavers can shift and move over time due to various factors such as ground movement, poor installation, and dramatic temperature changes.
Pavers do settle, so there is a certain amount of time after laying them that they will be usable. Once natural stone pavers are installed, they cannot be moved. Any water that collects on them has to be drained away before new ones can be laid.
Here's why: dirt shrinks by 30% when compacted. That means, if you backfill with dirt, your hardscape will settle 30%. This becomes an issue because, if you backfill with 10″ of dirt, your pavers will settle around 3″ over time. However, if you properly lay a gravel base, you'll essentially eliminate settling.
Runoff and drainage issues can affect a variety of things on your landscape, including your patio. You don't want water pooling up on your pavers, possibly causing problems with the foundation. To keep that from happening, make sure your pavers are slightly higher than the ground surface all of the way around.
Most experts recommend waiting for at least 24 to 48 hours before sealing the new pavers after installation.

Thick pavers are less likely to crack under the intense weight of cars. How thick should driveway pavers be? Weather conditions and soil texture are key elements determining driveway thickness. But it is generally recommended to lay between 2 inch thick pavers to 3 inch thick pavers.
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.
In order to keep your pavers from fading, it is important to seal them. Even the toughest of pavers don't stand a chance against the sun, with concrete even fading over time because of the UV rays.
Once the silica joint sand has been activated by the urethane in our Ure Seal h2o brick paver sealant, the 4 grain silica sand will become extremely hard, comparable to the consistency of concrete.
Joint stabilization – If you don't have Sand in the joints, rainwater or pool water will run between the brick paver joints and wash out the base aggregate sand material your brick pavers float on (usually a 1″ – 2″ sand base), making your brick pavers lose, shaky, uneven, sunken in or even raised in some areas.
Estimating the Paver Sand
The final paver sand depth needs to be 1 inch and you need to account for sand filtering into the paver base and into the joints between the pavers. Make your calculations using a sand depth of 2 inches or 0.1667 feet.
In case of bad weather, you will again face two options: If there is a huge downpour, it's best to postpone the process. Sand will surely get wet and wash out of the joints, so it is best to reschedule and start from the beginning. If there is light rain, you'll most likely have nothing to worry about.
They're nestled on top of a bed of compacted sand. For the most part, they stay secure. But over time, the sand settles into the ground, making the pavers lopsided. Gaps in the sand underneath cause pavers to wiggle loose.
Before you begin laying pavers, prepare the ground. Ensure you have a root and rubble free compatible sand sub-base of at least 50mm thick. The sub-base should be roughly levelled and damped down before tamping down firmly with a hand or mechanical compactor.
As to whether one should leave a gap between concrete pavers, the short answer is yes. However, the size of the gap will depend on the type of paver as well as the type of paving. For instance, if you're laying concrete pavers for a patio, make sure they're close together with edges touching.
The importance of compacting pavers after laying them cannot be overstated. Skipping this step in the process can lead to a weaker pavement surface and the ultimate failure of the jointing compound.
You must compact your base in layers of 3″ – 4″. If you've decided on a 6” base, you'll want to fill and compact your base in multiple phases. If your base materials are dry, don't be afraid to add a little water. This will help with the compaction, and cut down on the dust.
To fix a sunken patio, first pry up the paver with a thin screwdriver, pounding on adjoined pavers to vibrate packed sand loose. After a few years, paver block patios and walkways often develop low spots. However, these areas can be brought back up to grade with a few bags of sand, a length of pipe and a screed board.
