Polymeric sand is a material used to fill paver joints, the empty spaces found between each paver, tile or natural stone. It is sometimes called jointing sand, paver sand or hardscape sand. Polymeric sand is appreciated by paver installers because joints you get from it are durable and even .
Is paver sand necessary?

Does paver sand Harden?
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. However, once water is applied, any remaining polymeric sand particles will harden and remain on the surface resulting in an unhappy customer.
Why do you put sand between pavers?
Sand Between Pavers Filling gaps between pavers helps lock the individual bricks in place so they don’t shift. Once all the pavers are set in place, spread more sand over the top of them. Sweep the sand between the joints with a push broom. Sand between pavers creates friction that locks everything together.
What’s the difference between paver sand and regular sand?
Polymeric sand is a particular type of sand that, when mixed with water, creates a binding agent extremely powerful that binds the sand particles together. So, in the end, paver sand is nothing more than all-purpose sand mixed with specific water-activated bonding agents, but mostly polymers and silica.
Is paver sand the same as leveling sand?
The first is called by many names: all-purpose, leveling, or paver sand. These are all the same sand and are spread over the leveled ground on top of the landscape fabric, but beneath the PaverBase and pavers.
Will paver sand wash away?
However, since pavers are exposed to various elements such as rain and wind, the joint sand between pavers may get washed out overtime. Occasional washing can also cause the joint sand to corrode.
What can I use instead of polymeric sand?
Builder’s sand is the most common replacement for polymeric sand, as it is easy to access and not expensive. It is used heavily in construction projects, hence its name. Because this sand is very coarse, you will need to use it regularly. You’ll have to reapply it for years as it settles.
Will water drain through polymeric sand?
Installing polymeric sand involves more than just sweeping and watering. That is because this will harden and not allow water to drain through, keeping the water below the pavers and saturating the joints, not allowing the polymeric sand to properly dry and never set.
How often should you re sand pavers?
If you use regular sand, you may have to re-sand pavers every two years. But, other indicators may mean that the time has come. If joints are open, it means that any sand in there to keep the brick stable, keep them from moving, was washed off.
Is polymeric sand better than regular sand?

It outperforms regular sand when a homeowner is looking to lock the paver joints properly and wants a steady and stable path. It also provides a better appearance with its cleaner look and availability in varied colors.
How do I stop my pavers from sinking?
Compacting causes the stones to form a tight bond with the bedding layer, which reduces the chance of your pavers sinking again. Sweep joint sand into the joints between the pavers. Do this by pouring a pile of sand on your hardscape and sweep it over the stones until your joints can’t hold any more sand.

Should I use paver base or sand?
A walk or patio requires a 4-inch layer of compacted paver base, while a driveway needs a 12-inch layer. Some paver manufacturers recommend a 1/2-inch layer of sand when installing their products.
Does polymeric sand stop weeds?
Many owners will opt for merely topping up the low joints with new polymeric sand. Not only will this keep weeds out indefinitely, but it will also bring back the interlocking structural strength that polymeric sand provides to the paver system.
Does paver sand need to be compacted?
Not compacting the base Before laying bedding sand or pavers, your gravel base needs to be flat and firm, without any bellies or rises of more than 1/8″. You accomplish this kind of precision by properly compacting your base and your pavers. If you fail to compact, you’ll experience sunken or raised pavers.
Is paver base good for drainage?
Crushed stone makes a solid paver base because it allows water drainage and is easy to work with. Like sand, crushed stone comes in several varieties. The best aggregate for paver bases is a quarry processed dense grade aggregate.
Can you lay pavers on sand only?
The vast majority of sand you see is just small pieces of rock. On some beaches it can be tiny pieces of sea shells or broken coral. In other words, compacted sand can provide a sufficient base for a paver patio that’s just going to have you walking across it.
How long does it take for polymeric sand to harden?
A minimum of 24 hours drying time is required prior to allowing significant foot traffic and 48 hours for vehicular traffic on the paver surface. Polymeric sands are designed to soften and re-heal.
Can you seal over polymeric sand?
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.
