Buying Guide: Key Purchase Considerations

  • Joint width compatibility: Look for products that support a wide range of joint sizes (e.g., 1/8” to 4”). This reduces the need to buy multiple products for different projects.
  • Wet vs. dry application: Some polymeric sands are designed for wet application, allowing use in various weather conditions without delaying projects. Consider your local climate and project timeline.
  • Color and aesthetics: Colors like grey, dark grey, and beige coordinate with common paver palettes. Matching color helps conceal minor contrasts and achieve a uniform look.
  • Durability and weather resistance: Ceramic or advanced polymer blends offer improved durability against freeze-thaw cycles, wind erosion, and UV exposure.
  • Ease of use: Features such as easy-pour bags, ready-to-use formulas, and included tools (like grout floats) can speed installation and reduce labor.
  • Maintenance: Some products allow easy resealing of leftover material for future projects, which minimizes waste and cost per project.
  • Surface compatibility: Ensure the product is suitable for pavers, flagstone, and other outdoor surfaces you own. Some formulations are better for false joints or specific paver types.
  • Environmental and safety considerations: Check for low-dust formulations and any special handling instructions to protect your family and landscaping.
  • Cost and coverage: Compare coverage per bag or per bucket, and estimate how many units you’ll need for your patio area to avoid shortages mid-job.
