How often should you apply polymeric sand to pavers?

Polymeric sand is a type of sand that contains additives to harden when exposed to moisture, commonly used in paver joints to provide stability and inhibit weed growth. How often polymeric sand needs to be applied depends on several factors including its type, weather conditions and how often foot traffic hits that installation.

Polymeric sand typically doesn’t need to be applied regularly; here are some guidelines:

1. Initial Application:** Once pavers have been set into place and polymeric sand has been distributed between joints using a trowel, water must be added to activate its binding properties in order to form solid joints when it dries and hardens. Performing an initial application properly is key and should adhere to manufacturer specifications regarding your chosen product.

2. **Reapplication**: Over time, polymeric sand may begin to wear down due to weather conditions, erosion and usage. Reapplying polymeric sand when you notice significant erosion of joints, loose sand becoming loose or gaps appears is recommended.

3. **Repeat Application** On average, polymeric sand should be reapplied every two to five years; however, this could vary if areas with heavy rainfall, extreme temperature swings or high foot traffic require more frequent applications.

4. Inspection:** Periodically review the condition of your paver joints to detect any changes to their condition, such as loose joints or signs that polymeric sand needs replacing. If it becomes apparent that its quality has diminished over time or new weeds begin to form between pavers, this indicates the need to reapply polymeric sand to your system.

5. **Proper Maintenance:** To prolong the lifespan of polymeric sand installations, proper maintenance must be provided on an ongoing basis. Cleaning and sweeping can prevent debris and organic material from building up in joints and leading to erosion issues.

Keep in mind that your recommendations may differ depending on the brand and type of polymeric sand you use, as well as local climate conditions. For the best guidance in applying and reapplying polymeric sand onto pavers, always refer to manufacturer’s instructions for best results.
