It includes what it is, how to use it, and why it’s essential. We’ll also provide tips on choosing the suitable joint sand for your project.

What is a paver joint sand?

A paver joint sand is a type of sand used explicitly to fill the joints between pavers. It is different from other types of sand because it is specifically designed to resist erosion and help keep the pavers in place. Paver joint sand can be made up of different materials. One commonly used type of paver joint sand is polymeric sand. 

Polymeric sand is a man-made product that contains quartz, binding agents, and water. It hardens when it comes into contact with moisture and creates a solid bond between the pavers. This type of sand is a popular choice for paver joints among homeowners because it is effortless and creates a solid bond.


Another type of paver joint sand is acrylic sand. Acrylic sand is a natural product that contains quartz and binding agents.

However, the type of sand we use at Expert Sealers is a 20-30 fractured angular sand, also commonly known as silica sand or “pool filter” sand. The biggest benefit of this type of sand is its shape. Spherical sand (e.g. ‘play’ sand) forms a tightly locking barrier in the joints through which sealer is unable to pass, and it can be easily dragged out by factors such as car tires. Fractured angular sand has an irregular, jagged shape which forms voids in the joints allowing the sealer to pass through and establish an extremely strong, long-lasting bond.

How to use paver joint sand?

Applying paver joint sand can be tricky at first but it’s straightforward and quite rewarding once you get the hang of it. The sand is washed into the joints using water to make sure they’re filled correctly. The water will cause the sand to harden and create a strong bond between the pavers. Paver joint sand is a great way to add strength and stability to your next project. It is easy to use and creates a strong bond between the pavers. 

Why is paver joint sand important?

Paver joint sand is essential because it helps to keep the pavers in place and prevents them from shifting. It also helps to resist erosion and keeps the pavers looking new. Paver joint sand is a great way to add strength and stability to your project. It is easy to use and creates a strong bond between the pavers.
