Polymeric sand is simply a granular sand material that is placed within the cracks and joints between stone pavers as a means of interlocking the units and preserving the beauty and integrity of the pavers. A water-activated polymer is introduced to the sand.
What is the best sand for interlocking pavers?
When the last of your interlock pavers or interlocking patio stones get installed, the gaps between each individual stone need to be filled with something. That something is polymeric sand which is the best sand to use for pavers. And the reason for it lies in its composition: Fine quartz particles.
What type of sand do I use under pavers?

What kind of sand is used for interlocking bricks?
Polymeric Sand is as ubiquitous to interlocking pavers as garden soil to gardening.Can I use regular sand to lock pavers?
Can I Use Regular Sand Between Pavers. Yes, normal sand serves this purpose very well. Fill gaps between pavers and help lock the individual blocks in place, so they don’t shift. If possible, use irregular, sharp-grained sand, as they have sharp edges and bind together better.
Which Polymeric sand is best?
- BEST OVERALL: DOMINATOR Natural Joint Stabilizing for Pavers.
- BEST BANG FOR THE BUCK: Sakrete Paver Set Joint Sand.
- UPGRADE PICK: Alliance Gator Maxx G2 Intelligent Polymeric Sand.
- BEST FOR SMALL PROJECTS: DOMINATOR Joint Stabilizing for Pavers.
What is the difference between paver sand and polymeric sand?
Polymeric sand is the more reliable and durable option for filling in the paver gaps. 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 you get polymeric sand off the top of pavers?
- To begin, avoid any contact with water or moisture before cleaning. …
- Sweep the surface with a broom with soft bristles. …
- Repeat step two as many times as necessary to remove as much polymeric sand as possible. …
- Use a leaf blower to blow off any leftover.
How do you harden sand between pavers?
As we brought up earlier, regular sand doesn’t harden enough on its own. So, if you need it to set, the best way to do it is by sealing them. You should give it at least 48 hours after applying the sealer. Foot traffic is ok after 3-4 hours.
What is polymeric sand?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. Jointing sand is made up of fine grains, to which manufacturers add a mixture of specific additive particles.
Article first time published onIs play sand the same as mason sand?
Uses. Of course, the greatest difference between masonry sand and play sand is how each type of sand is used. Masonry sand is commonly used to make smooth concrete and mortar for brick-laying. … Play sand is used almost exclusively in sandboxes.
How thick should sand be under pavers?
Plan on spreading about 1 inch of sand beneath the pavers, says Western Interlock. You’ll also use it to fill the gaps between them. The sand should be spread over a 4- to 12-inch layer of crushed stone, which has been tamped into place.
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.
Is leveling sand the same as polymeric sand?
Polymeric sand is not used in all hardscaping projects. It may not even be the most popular option. All-purpose sand is the go-to product for sealing paver joints. This sand is also known as joint sand or leveling sand.
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.
How far does a bag of polymeric sand go?
When filling small gaps, a 50lb bag of polymeric sand will usually cover 75-100 ft2. When filling wide gaps of 1/4″ to 3/8″ a 50lb bag will usually cover 30-60 ft2. Wider gaps, for example with a flagstone patio, will require even more sand to fill.
Is polymeric sand permanent?
Polymeric sand relies on a chemical reaction to harden it into the joints between your paving stones. Once it hardens, it is permanent.
Is there a difference in polymeric sand?
The key difference between polymeric sand and polymeric dust boils down to the size of the joints between the stones. In applications that have larger, natural stones with irregular contours, it can be difficult to create consistent ½” joints. For these jobs, polymeric dust would be the ideal product to use.
How thick should polymeric sand be?
We recommend the joint width between your pavers be between 1/8th of an inch and 4 inches and the joint depth to be at least 1 inch. This allows you to get the best bonding performance from your polymeric sand.
Can I use a hand tamper for polymeric sand?
Using a broom, spread sand over the patio and into the gaps between the pavers. … Once you have swept the sand into the paver joints, a hand tamp should be used over the entire paver area in order to “vibrate” the sand further into the joints.
Does polymeric sand Harden?
Polymeric sand cures by drying. And in order to fully set, it needs to dry out completely. 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.
Is polymeric sand waterproof?
Most polymeric sand varieties can only be activated once and are waterproof thereafter. However, there are varieties available that have the ability to be softened by water to facilitate the correction of minor imperfections. Twenty-four hours are required for the pavers to lock completely.
Do I need a compactor for polymeric sand?
One of the most important steps in a polymeric sand installation is proper compaction of the sand into the joints. Ideally this is done using a vibratory plate compactor. … This is why it’s important to sweep in more sand to ensure the joints get filled up to 1/8 inch (3mm) below the paver’s edge or chamfer.
Is polymeric sand flexible?
Polymeric sand’s unique binding agent is flexible enough to maintain its structure over time, but will not yield to the elements. Polymeric sand will stand up to water especially well. There’s no need to worry that sand might wash out of the joints after heavy precipitation or even power-washing.
Can you add polymeric sand over polymeric sand?
You have to completely remove all the pre-existing sand in the joints and start fresh. … Secondly, you will have to wait a day while the surface dries before you can reapply your new sand. Remember polymeric sand and moisture don’t mix until after it’s in the joints!
How do you replace polymeric sand between pavers?
To replace sand that has been washed out, simply pour joint sand over the pavers. Next, sweep it into and across the joints using a stiff push broom. Keep the depth of the sand at ¼ inch from the surface of the paver. Afterwards, you can sweep the excess joint sand between pavers and store it again for future use.
How do you make polymer sand?
