Using Regular Joint Sand for Pavers

How Do You Use Joint Sand?

Joint sand is used to fill the gaps between paving stones, creating a stable and attractive surface. The process varies slightly depending on the type of sand (regular joint sand or polymeric sand), but the general steps are similar.

This method is best for smaller gaps between pavers.

1. Preparation: Ensure the pavers are firmly in place.
2. Application: Pour the sand evenly over the pavers.
3. Sweeping: Use a large broom to sweep the sand into the joints, filling them completely.
4. Compaction: Compact the pavers using a hand tamper to settle the sand.
5. Excess Removal: Use a blower to remove any excess sand.

This process is described in multiple sources: Western Interlock's step-by-step guide and a May 31, 2024 article which states, "Pour sand over your pavers, then sweep it evenly into the joints using your large broom. Compact the pavers down once more using a hand tamper. Once you have made sure every paver joint is full of sand, use your blower to get rid of any excess."

Using Polymeric Sand for Pavers

Polymeric sand offers superior strength and weed prevention compared to regular sand. It's ideal for larger joints and areas exposed to significant traffic.

• Note: Polymeric sand requires specific application instructions which vary by brand. Always follow the manufacturer's directions. However, general steps include:
  • Ensure pavers and joints are dry. (See Black Diamond Coatings' article on common mistakes highlighting the importance of dry pavers.)
  • Apply the sand according to the manufacturer's instructions, usually involving sweeping and compacting. Sakrete's blog post notes that polymeric sand works best when filling the entire depth of the paver joint, ideally between ¼ inch and 1.5 inches.
  • Activate the polymeric component as per the instructions (often involves adding water).
  • Allow sufficient curing time before using the paved area. Some high-performance options like Techniseal's HP Nextgel are designed for concrete and clay pavers, natural stone, and porcelain tiles. Products like Gator Supersand G2 are formulated for joints up to 2 inches. Easier-to-use options like EasyJoint Paver Joint Sand utilize water to assist filling.

Filling Deep Expansion Joints

For very deep expansion joints, regular sand may not be sufficient. Consider alternatives like expanding foam, backer rod, and a suitable sealant, as suggested in a Reddit thread discussing filling deep expansion joints: r/Concrete discussion.
