What is Polymeric Sand?

Polymeric sand is a blend of fine sand particles and special polymers that are activated with water. When properly applied and cured, it forms a strong and durable bond that locks pavers together, inhibiting weed growth and resisting erosion caused by wind, rain and foot traffic. Unlike traditional sand, polymeric sand hardens when exposed to moisture, creating a solid, yet flexible, joint filler.

Advantages of Polymeric Sand

  1. Strength and Durability: Once activated, it creates a resilient bond that helps to stabilize pavers, reducing shifting and settling over time.
  2. Weed Inhibition: The polymer additives in polymeric sand create a barrier that inhibits weed growth, keeping your paved surfaces looking pristine with minimal maintenance.
  3. Enhanced Aesthetics: It comes in a variety of colors to complement different paving stones, providing a polished finish that enhances the overall appearance of your outdoor space.
  4. Joint Stabilization: By filling the joints between pavers, polymeric sand helps to prevent sand loss, erosion and weed infestation, ensuring long-lasting structural integrity.

How to Use Polymeric Sand

  1. Preparation: Before applying it, ensure that the paving stones are clean, dry and free of debris. Sweep any loose sand or dirt from the joints to create a clean surface for the sand to adhere to.
  2. Application: Pour the polymeric sand evenly over the paved surface, ensuring that the joints are completely filled. Use a broom or brush to sweep the sand into the joints, ensuring full coverage and eliminating any air pockets.
  3. Compact the Sand: Once the joints are filled, use a compactor or tamper to gently compact the sand into place. This helps to ensure proper adhesion and eliminate any excess sand on the surface.
  4. Activation: After compacting, mist the paved surface with water using a gentle spray. Be sure to thoroughly wet the sand, allowing the polymers to activate and bond with the surrounding particles.
  5. Removal of Excess Sand: After the sand has been activated, use a broom or brush to sweep away any excess sand from the surface of the pavers. This will help to prevent haze or residue from forming as the sand dries.
  6. Final Cure: Allow the polymeric sand to cure according to the manufacturer’s instructions, typically for 24-48 hours, before subjecting the paved surface to foot traffic or heavy loads.
