Best Sand for Pavers – Buyer’s Guide

Some things aren’t exactly household names but prove quite useful for various projects. Polymeric sand is one of those things.

Still unsure what polymeric sand is, what it does, and what it’s all about? Let’s delve deeper into this unique paver sand alternative to learn what it’s all about.

What is Polymeric Sand?

Polymeric sand is a material used to fill the seams or joints between brick, stone, and concrete pavers. It’s comprised of fine sand and special polymer additives, which bind the sand particles together when wet to improve the stability and durability of a paved surface, such as a patio or walkway.

The ingredients in polymeric sand differ from one manufacturer to the next, but most generally contain crystalline silica or quartz. In fact, up to 80 percent or more of many polymeric sands contain these or another polymer component.

Polymeric Sand vs Regular Sand for Paver

Ordinary sand was used to fill in the joints between pavers for centuries. Unfortunately, plain old sand washes out and needs constant upkeep and replacing.

Polymeric sand changed the game. Utilizing advanced polymer materials, it’s superior to ordinary sand in a number of ways, including:

• Improved durability. The polymers help lock pavers together for long-lasting strength and durability.
• Fewer wash outs. Regular sand is prone to washing out after heavy rains, which can jeopardize the foundation of any paver project. Polymeric sand, on the other hand, doesn’t wash out and stays locked in place.
• Fewer weeds. Weeds are incredibly resilient and can sprout up virtually anywhere. While polymeric sand can’t guarantee a weed will never sprout up in your patio or walkway, it will definitely help.
• No more ants. It’s almost impossible for ants to crawl into and make a home in between pavers bound with polymeric sand.
• A variety of colors to choose from. Unlike regular sand, polymeric sand comes in a variety of colors and shades to complement an array of pavers, stones, and outdoor designs.

How to Apply Polymeric Sand

The application of polymeric sand is the same as any other paver joint stabilization sand. Before you begin, check the forecast and pick a day, or a few days for that matter, with dry, sunny conditions.

Once you’ve done so and the day arrives, sweep the polymeric sand between the pavers and into the joints. Then, compact the sand and the pavers.

Some professionals recommend doing this process twice and topping off the joints with a third sweep of sand in order to avoid the slightest chance of weeds finding a way through.

When the sand has been swept in nice and tightly into the paver joints, use a blower or broom to make sure none is left on any of the pavers prior to wetting.

This brings us to the final step: wetting the polymeric sand so it can set. However, before discussing this last step, it’s important to note that manufacturers have begun making changes to their installation instructions in the past five years as neer formulas have been introduced. So, carefully read and follow the instructions.

That being said, in most cases, you should begin at the highest point of the paver surface and gently spray a mist of water over the paved area as you work your way toward its lowest part. The sand and the pavers should be lightly soaked, not drenched.

The mist will activate the polymers and begin to harden the sand. Most polymeric sand manufacturers recommend letting the sand set and cure for 15 minutes or so and then giving the paved area another light mist.

Depending on the polymeric sand you choose, it will take 24-72 hours to fully activate and harden. However, if the project is located in a sunny area, you should be able to walk on it in as little as 30 minutes without the sand sticking to your shoes.

FAQ

Can polymeric sand be added on top of existing joint sand?

In order for polymeric sand to harden and set properly between stones or pavers, it must fill the entire joint from bottom to top. Simply adding polymeric sand on top of existing sand will not make the joints impermeable to weeds, ants, and wash outs or erosion.

If you’re renovating a patio or walkway with poly sand, all of the existing sand between the pavers should be cleaned out and removed with a hose or pressure washer. The area should then be allowed to dry before the new poly sand is applied.

Is polymeric sand safe?

According to the MSDS of many manufacturers, breathing masks should be worn when using their poly sand products. While there is no concrete data on whether or not the polymers in polymeric sand are harmful, the inhalation of silica over a prolonged period can lead to inflamed and scarred lung tissue, a condition known as silicosis.

When left unchecked, silicosis can also lead to lung fibrosis and an increased risk of developing tuberculosis. Although silica can be found in many other products in addition to polymeric sand,  it’s best to follow manufacturer recommendations and utilize some sort of breathing protection while using this form of the binding agent. 

What is the ideal temperature for applying polymeric sand?

Most poly sand manufacturers recommend a minimum ambient temperature just above freezing when applying their products. However, some suggest an even higher minimum temperature of 40-50 degrees Fahrenheit for better binding and results.

Is polymeric sand okay to use around pools?

Yes, it can be used in pool areas. However, organic “enviro” sands have a tendency of re-softening when they get, which makes them more susceptible to wash outs. Not only will the sand wash right into your pool, but you’ll need to constantly re-apply.

The Bottom Line

If you have a paver project, polymeric sand will become your new best friend. In addition to sealing and seamlessly tying your patio or walkway pavers together to form a cohesive look, poly sand will stabilize the joints, keep weeds at bay, and more.

As you can see, there are some excellent yet very different products on the market to choose from. One may be right for your neighbor, but not right for you.

Are you on a tight budget? Do you like instant results? Would you prefer overall performance and long-lasting results? Each of the polymeric sands above is great in their own way, but your answers to these questions will help you determine the best one for your paver project. Happy paving!
