Poly sand typically needs to be replaced every 2–3 years to ensure proper joint stability and protection. Over time, natural wear, weather exposure, and foot or vehicle traffic can erode the sand, reducing its effectiveness. Regular replacement helps maintain the integrity of your paver surfaces.

While poly sand significantly reduces weed growth by hardening into the joints, it doesn’t completely stop surface seeds from germinating. Regular cleaning, sweeping, and occasional maintenance can help keep your paver surfaces free of weeds.

Yes! Poly sand works well with most types of pavers, including concrete pavers, brick pavers, and natural stone. However, for the best results, pavers should have joints deep and wide enough to properly hold the sand.

If old poly sand isn’t replaced, joints may begin to erode, allowing weeds, moss, and insects to infiltrate. This can cause pavers to shift or settle, leading to uneven surfaces and potential damage. Regular maintenance ensures your pavers remain stable and attractive

If you notice moss, sand turning white, or missing sand in the joints, it’s time to replace your poly sand. Other signs include weed growth, pavers shifting, or water pooling in the joints, all of which indicate the need for maintenance.

Poly sand can turn white due to excess moisture during the curing process. When too much water is applied, or if the area experiences rain or high humidity before the sand fully cures, the binders in the sand can rise to the surface and create a white haze. This is known as polymeric haze and is a common issue when the installation conditions are not ideal.

Other causes of white discoloration include:

• Overwatering: Applying too much water during activation can wash out the binders, leaving a chalky residue.

• Improper Cleaning Before Application: Dirt or dust left on the surface of the pavers can mix with the sand and cause discoloration.

• Using Low-Quality Sand: Lower-grade polymeric sands are more prone to hazing due to inconsistent binders.

At Exoclean, we take care to follow the correct application process, ensuring the pavers are clean and the proper amount of water is used to prevent white haze. If poly sand turns white, the surface can often be cleaned with a specialized cleaner or lightly reinstalled to remove the residue.

Yes, at Exoclean, we guarantee the quality of our polymeric sand installation services. If the sand does not set correctly or fails within the first 6 months, we will address and resolve the issue at no additional cost.

Sometimes, issues can arise due to factors like a bad batch of polymeric sand or unexpected environmental conditions. While rare, we stand by our work and the products we use, ensuring your pavers are stabilized and your outdoor spaces look their best.

For long-lasting results, we recommend regular maintenance, such as cleaning and inspecting your paver joints, and reapplying poly sand every 2–3 years.

Yes, polymeric sand installation can help increase your property value by improving the appearance, durability, and functionality of your outdoor spaces. Stabilizing the joints between your pavers creates a clean, polished look that enhances curb appeal. Well-maintained patios, walkways, and driveways are attractive to potential buyers and demonstrate pride of ownership.

Additionally, polymeric sand protects your pavers from erosion, shifting, and weed growth, ensuring they remain in excellent condition for years. Investing in polymeric sand installation with Exoclean not only improves your outdoor spaces but also contributes to the overall value of your home.

Polymeric sand installation is a two-day process to ensure proper preparation, application, and curing for long-lasting results. On the first day, we use a turbo nozzle attachment on a pressure washer to thoroughly clean the paver joints. This step removes old polymeric sand, debris, weeds, and other materials to create a clean foundation for the new sand. During this process, the joints do get wet, which is essential for clearing out all debris effectively.

After the cleaning is complete, the pavers and joints are left to dry completely overnight to ensure the new sand can settle properly during the next stage.

On the second day, we fill the joints with polymeric sand, ensuring it sits 1/8th of an inch below the bevel of the pavers for a clean and polished finish. Once the sand is in place, it is carefully activated with water, allowing it to harden and create a durable, weather-resistant bond. This curing process typically takes 24 hours, during which the surface should be kept free from traffic or additional water exposure.

To ensure the polymeric sand sets correctly and stabilizes the joints effectively, it’s important to follow a few precautions:

1. Turn Off Sprinklers: Water exposure during the curing period can prevent the sand from hardening properly. Make sure all sprinklers are turned off until the curing process is complete (usually 24 hours).

2. Avoid Watering Nearby Plants: Refrain from watering plants that are close to the paver surface during the curing time to prevent water from disrupting the joint stabilization process.

3. Wait Before Moving Furniture: If the area has outdoor furniture, avoid placing it back on the surface until the sand has fully cured. This helps keep the joints intact and undisturbed.

By taking these simple precautions, you can ensure the polymeric sand properly stabilizes your paver joints, enhancing the durability and appearance of your outdoor space.
