Paver sand is an important component of any paver installation as it provides several necessary functions. It is used to fill any joints between the pavers and is an essential ingredient for providing stability and preventing weeds from growing through the cracks.
The type of sand you should use when installing pavers depends on the type of paver you’re using and the purpose it will serve. For example, if you’re installing a paver driveway or a walking path, you should use coarse sand with a texture similar to beach sand (18-20 silica content).
You’ll want to use masonry sand for setting or flagstone pavers. Masonry sand is finer than regular play sand and has both larger and smaller particles. The larger particles will give your pavers a bit of cushion when someone walks on them.
It’s also helpful to use a compaction aid such as polymeric sand when there are smaller joints in between the pavers. This type of sand will help keep the joints from becoming unstable. Ultimately, the type of sand you’ll need for your paver installation will depend on the type of pavers you’ve chosen and the function of the project.
Are all polymeric sands the same?
No, all polymeric sands are not the same. Although they all contain some type of polymeric binder and sand, they can vary in terms of their composition and use.
Many polymeric sand products are blends of both quartz and ceramic sands and the formulation of the binder. These sands can be further customized to meet specific customer requirements such as curing time, color, and strength.
For example, polymeric sands may be used for joints up to two inches thick, but there are also special polymers that can be used in joints as wide as two inches or even three to four inches. The polymeric sand may also be engineered in different ways to be water-resistant, freeze-thaw, or corrosion-resistant in certain weather conditions.
When it comes to deciding which polymeric sand is best for a project, it is important to consider each sand’s benefit for the application and its ability to meet specific site needs. So, it is important to look not only at the composition and formulation of the binder but also the site conditions and purpose of the project.
Only then can you determine the best type of sand to use.
What are the problems with polymeric sand?
Polymeric sand is a commonly used material on outdoor hardscapes such as patios and walkways. While the product has some advantages, it also has some drawbacks that you should be aware of before starting any project.
The first problem with polymeric sand is its tendency to harden quickly. Once it’s laid, it sets in minutes and any mistakes or adjustments need to be done in that same window. This means that you’ll need to be extra careful when installing it, as it will be very difficult to make any changes once it has hardened.
Another drawback to polymeric sand is the cost. It tends to be much more expensive than traditional sand, and it’s also not very eco-friendly due to the chemicals used in its production. It can also be difficult to find, as not all hardware stores stock it.
The last problem with polymeric sand is its tendency to wash away with heavy rains. This can be very problematic for outdoor hardscapes, especially if you live in an area with frequent rain. To counter this, you’ll need to make sure to slope all of your hardscaping away from any buildings or other structures so that the rainwater can drain properly.
You should also add a layer of gravel or a sealing product in order to better secure the sand and prevent it from washing away.
Overall, while polymeric sand has some advantages, it also has some drawbacks that should be taken into consideration before starting any project. Make sure to do your research and consider all of your options before choosing the products you’ll be using.

What is a good polymeric sand?
A good polymeric sand is a type of sand specifically designed for use with interlocking pavers and flagstones on walkways and patios. This type of sand contains a water-activated bonding agent that helps the sand to bind together similar to mortar and fill the space between each paver, helping to prevent weed growth and the escape of storm water.
It’s important to use the right type of sand for this application and a good polymeric sand is often recommended as it contains specially graded sand and are mixed with a powder or liquid binder that is activated by water.
Polymeric sand may be preferred over other types of sand because it comes in a range of colors, including natural shades, and can create an attractive joint that complements the surrounding landscape.
Additionally, it’s designed to alleviate drainage problems, reduce the growth of weeds and inhibit ants, so it offers a high degree of protection that is not readily attainable with other types of sand.
Can you power wash polymeric sand?
Yes, you can power wash polymeric sand. However, it is important to take care when doing so to ensure the pressure of the power washer is not too strong. If the pressure is too strong, it can damage the polymeric sand, causing it to break down and lose its bonding properties.
It is also important to angle the nozzle of the power washer downwards. This will allow the force of the water to effectively break up clumps of sand and other debris without harming the polymeric material.
It is also advised to make multiple passes over the affected area to loosen up any dirt or debris that may have accumulated.
When should you not use polymeric sand?
Polymeric sand should not be used in areas that are prone to heavy rainfall or flooding, as the sand is likely to be stirred up and washed away or carried into nearby vegetation. Additionally, it should not be used on a newly seeded lawn, as it could prevent grass seedlings from reaching the soil below, or in existing vegetation, since it could block the growth of root systems and cause damage.
Furthermore, polymeric sand should not be used in areas with water features such as fish ponds, as the chemicals used in the sand could harm fish or other aquatic life. When working with flags and slabs, it also should not be used as it can cause them to crack as a result of increased pressure from the sand.
Finally, it should not be used in unpaved areas, such as pathways and gardens, as it can transfer its color to clothing and other fabrics.
How long should polymeric sand last?
Polymeric sand typically lasts up to 15 years when properly installed, but can last even longer in some cases. It is important to ensure the joints are filled completely with the sand to provide extra support and protection against erosion and weeds.
The sand should also be compacted at least twice to improve interlocking and prevent erosion. When installed correctly and without any behavior that could compromise the integrity of the joints, it can last for decades.
Additionally, if the area is periodically swept and/or sprayed down with a garden hose to keep weeds at bay, the sand will last even longer.

Can polymeric sand ruin pavers?
Polymeric sand can certainly have a negative effect on pavers if it is not installed and maintained properly. If the sand is not applied according to the manufacturer’s instructions, the paver joints may be too small, which can cause the pavers to bind together and put tremendous stress on the pavers.
This can then cause the pavers to crack and buckle, becoming loose and uneven.
In addition, when polymeric sand is exposed to water, it can expand, causing the pavers to separate and causing cracks and other damage. If the pavers are exposed to high temperatures for an extended period of time, the polymeric sand may also create an adhesive that can bind the pavers together, making them difficult to separate or shift.
Overall, the best way to ensure that your pavers are safe from damage from polymeric sand is to follow the manufacturer’s instructions for application and maintenance and to keep a close eye on the condition of your pavers.
If any changes are noticed, it is best to have a professional look at the pavers and make any necessary repairs.
Should I use polymeric sand or regular sand?
The type of sand you should use really depends on the project you’re completing. Generally, when installing pavers or other hardscaping projects such as patios, walkways and driveways, polymeric sand is the best choice.
It’s specially formulated with a combination of fine sand and other additives so that it better binds together and locks in pavers. When correctly used, polymeric sand can help protect against weeds, erosion, and address issues like mud tracking in your patio or sidewalk.
Regular sand, on the other hand, is often used for children’s play areas or sandboxes. It’s a very loose material that is soft and cushions well, making it easier for kids to play. Regular sand can also be used as a filler between flagstones to increase traction so it’s less slippery when wet.
Ultimately, the type of sand you should use depends on the project at hand. Polymeric sand is great for hardscaping projects and regular sand is usually better for playgrounds or slippery surfaces.
Is polymeric sand necessary?
Polymeric sand is not a necessary part of any landscape project, but it can be beneficial in some applications. Polymeric sand is a type of sand that contains polymers that help bind the sand particles together.
This can make the surface of the paver project more cohesive, stable, and resistant to weed growth and the washout of fine powders. Polymeric sand can be used in place of regular sand between many types of interlocking pavers, including brick, concrete, and stone.
It is ideal for projects with high foot traffic, and can even help to prevent unsightly staining between the pavers. The polymers also help to prevent sand from washing away in high-rainfall areas, which can help to prevent sinking and settling of the pavers over time.
While polymeric sand is not necessary for all projects, it can be beneficial for certain applications.
Does polymeric sand affect drainage?
Yes, polymeric sand can affect drainage. It is made out of a blend of fine sand, polymer and other additives that are mixed together to form a water-resistant and binding material. The main purpose of using polymeric sand is to fill the joints between paving stones and provide an additional barrier against the elements.
When drainage is considered, polymeric sand provides additional support and stability to the paving stones, which can reduce the risk of runoff. The polymer and sand create a tighter joint between the stones, binding them together and creating a barrier for the water to travel through.
This forms a better seal when compared to the traditional stone dust. The polymer in the sand also reduces the movement of the stones and prevents erosion and debris from entering the joints.
This helps improve drainage by preventing too much water from pooling and increasing the risk of flooding. However, it’s important to understand that while polymeric sand will offer some protection, it shouldn’t be seen as a solution to a drainage problem.
The amount and direction of water flowing should be considered and an appropriate drainage system should be installed to ensure water is directed away from the area.
How long does it take polymeric sand to harden?
Polymeric sand typically takes between 24 and 48 hours to fully harden. It should be noted that weather conditions may affect the hardening time – if it is raining or extremely humid, it may take longer for the sand to settle and harden.
Once the polymeric sand has been applied, it’s important to keep the area damp for a period of time by using a garden hose or sprinkler. Once the polymeric sand has been applied, the area should be tamped gently and left to dry.
After the sand has settled, it’s important to make sure there is no standing water. Once the polymeric sand has had a chance to harden completely, water should be kept away from the area for several days to ensure it has cured correctly.
What is the difference between jointing sand and polymeric sand?
Jointing sand and polymeric sand are both used to fill the joints between pavers, such as in a patio or driveway. The primary difference between the two is the composition. Jointing sand is usually comprised of natural silica sand, while polymeric sand contains a blend of silica and other substances, usually polymer binders and finely ground sand particles.
Polymeric sand is more durable and provides a stronger stability for paving materials. Jointing sand does not contain the polymer binders and is not as effective in preventing weeds or insects from entering the joints.
It can however provide a smoother surface, which makes it ideal for application in between pavers with tight joints. As a result, jointing sand may be the preferred option for areas with more intricate designs.
Polymeric sand is most often used for walkways, driveways, and patios and is often referred to as ‘sweeping sand’ or ‘ant-sweep sand’. It will adhere to the paver surface and provide a sealant-like protective layer between the pavers.
Polymeric sand offers a greater level of protection against weeds, pests, and water erosion due to its higher level of binding ability. It is also less likely to wash away or allow insects to tunnel through, assuming the pavers have a good drainage system.
Does water go through polymeric sand?
No, polymeric sand does not allow water to pass through it. Polymeric sand is a type of sand that has been mixed with a special type of binder that helps the sand particles stick to each other. This makes the sand resistant to moisture and wind, and also helps form a strong bond between pavers and joints.
Polymeric sand helps to fill the gap between stones and create an impermeable barrier. This barrier helps to prevent water and other debris from entering in between each stone and makes sure the stones stay in place.
Without a barrier like this, water can seep into the pavers and cause them to shift or become damaged when it expands and contracts.
Is paver locking sand worth it?
Yes, paver locking sand is worth it if you are looking to protect and secure your driveway, patio, or walkway pavers. Paver locking sand, also known as polymeric sand, is a type of sand designed to stay firmly in place, locking pavers together and preventing weeds and ant hills from forming.
It is made of fine, natural sand particles and a mix of polymers that are activated by water. This creates a strong bond that will keep pavers in place, while still allowing them to move slightly to accommodate changes in the ground or temperature.
Additionally, paver locking sand helps protect against erosion, while preventing ants and other pests from accessing the area. In summary, paver locking sand is worth it if you want to protect and secure your pavers, as it will help reduce maintenance and protect against weeds, ant hills, and erosion.
