Why We Use Joint Sand Stabilizer when Paver Sealing

Why We Use Joint Sand Stabilizer when Paver Sealing
Before you use your new paver patio or driveway it’s important to make sure it is protected so you can enjoy it for years to come. After investing in a new paver patio or driveway we recommend joint stabilizing silica sand and sealer. This is a combination of using joint stabilizing silica sand and a liquid product that protects and penetrates both the paver and the sand in the joint as well. We prefer joint stabilizing paver sealer over Polymeric sand for several reasons.

Problems with Polymeric Sand

Polymeric sand is a unique mixture of fine sands combined with polymers. When these are mixed with water they form a binding agent that locks the sand particles together. This mixture fills joints between pavers. A drawback of the product is that it can cause staining on your pavers without proper application. In a damp environment, it can leave a haze (or an efflorescence) on the pavers; ruining the beauty of the colors of your pavers. Polymeric sand also does not fill joints as deeply as silica sand.

To remove the risk of staining your new pavers and stabilize them we prefer to use joint stabilizing paver sealer. This is a combination of a layer of regular sand with a sealer added on top.

What is Silica Sand?

Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral.

The presence of silica sand is in regular sand but the overall makeup differs chemically. Regular sand, also known as feldspathic sand, brown sand, or construction sand, can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals. This type of sand holds impurities that make it more chemically reactive as compared tosilica sand.

Why use Silica Sand Between my Cement Pavers?

Silica sand between pavers has both a functional and an aesthetic role. When properly sealed with a joint stabilizing sealer, the sand keeps your pavers from shifting out of place. Silica sand between pavers creates friction that locks everything together. Sand helps mitigate weed growth, as well as prevent moisture from seeping underneath the pavers.

Silica sand is easy to apply between concrete pavers and allows for a smooth surface between paving joints. For these reasons, we believe silica sand is the best paver sand to create a solid surface between paver joints.

Added Benefits of Using Joint Stabilizing Paver Sealer

Sealing your pavers using a joint stabilizing paver sealer enhances the natural colors of your pavers. The joint stabilizing paver sealers come in a matte sheen or high gloss sheen.

Sealing your pavers creates a barrier, locking out harmful moisture and UV rays. Sealing your pavers also inhibits the growth of algae, mold, and mildew, all of which are prevalent in humid areas. All sealers will wear away over time due to heavy rain, sunlight, and foot or tire traffic. It’s best to routinely clean and reseal your pavers every 2-3 years.

Paver sealing keeps your driveway curb appeal looking its best for longer by eliminating cracks between pavers. Sealing will extend the life of your pavers by increasing structural integrity, saving you money in the long run, and reducing the time you spend on house maintenance year over year.
