What is Joint Sand, and Why is it Important?
Joint sand is the fine material swept into the spaces between pavers. Its primary purpose is to lock the pavers together, prevent shifting, reduce weed growth, and deter insect infestations. Pavers can become uneven or unstable without proper joint sand, diminishing aesthetics and functionality.
Key Benefits of Joint Sand
- Enhances the structural integrity of paver installations
- Prevents weed growth and ant infestations
- Reduces water infiltration and erosion
- Offers a clean, finished look
Types of Joint Sand for Pavers
There are two main types of joint sand commonly used in paver projects:
1. Regular Joint Sand
Often referred to as “play sand” or masonry sand, this type is fine-grained and affordable but lacks bonding properties.
| Pros | Cons |
| Cheap and widely available | Easily washed out |
| Easy to install | It doesn’t harden or bond. |
2. Polymeric Sand
This type of joint sand contains fine grains mixed with polymer additives. When activated with water, it hardens to form a durable, flexible joint.
| Pros | Cons |
| Superior bonding and stability | More expensive than regular sand |
| Resists weed growth and ants | Requires precise application to avoid hazing |
| Long-lasting with minimal maintenance |

How to Apply Joint Sand: Step-by-Step
Step 1: Prep the Surface
Clean the surface of your pavers thoroughly. Using a pressure washer or stiff broom, remove any dirt, debris, or old joint material.
Step 2: Dry the Area
Ensure the pavers and surrounding areas are completely dry before applying sand, especially polymeric types, which require dry conditions before activation.
Step 3: Spread the Sand
Use a push broom to sweep the sand into the joints, working it back and forth until all gaps are filled.
Step 4: Compact the Pavers
Vibrating the pavers with a plate compactor or rubber mallet helps the sand settle deeper into the joints.
Step 5: Top-Off and Clean
Add more sand if needed. Sweep off any excess sand from the surface to avoid polymeric hazing.
Step 6: Activate with Water (Polymeric Sand Only)
Lightly mist the entire area to activate the bonding agents. Avoid over-watering, which can wash out the sand.
Maintenance Tricks for Perfectly Set Stones
1. Regular Cleaning
Regularly sweep away debris and dirt to maintain the appearance of your pavers and joint sand. A soft-bristle broom is ideal for this task.
2. Replenishing Joint Sand
Joint sand may wear away over time due to weather conditions or heavy foot traffic. Inspect your pavers annually and replenish the sand as needed to maintain stability and appearance.
3. Weed Control
To prevent weeds from breaking through the joints, consider using a weed killer or a natural alternative like vinegar. Regularly check for any signs of growth and address them promptly.
4. Sealing Pavers
Applying a sealant to your pavers can protect the surface from stains and enhance the color. Sealants also help keep joint sand in place, reducing the need for frequent replenishment.
5. Seasonal Maintenance
During winter months, check for ice accumulation in the joints. Use a plastic shovel to remove ice without damaging the pavers. In spring, inspect for any joint sand erosion and replenish as necessary.
Common Mistakes to Avoid
- Applying sand to wet pavers can cause clumping and improper bonding
- Not compacting after sand application — Leads to shallow fill and instability
- Over-watering polymeric sand — Can result in weak joints or surface hazing
- Ignoring manufacturer instructions — Always follow the specific guidelines on the sand product you choose
Final Thoughts
Joint sand is a crucial component of any paver installation. Whether you opt for traditional joint sand or advanced polymeric options, correct application and consistent maintenance will make a world of difference in the longevity and appearance of your hardscape.
Choosing the right product, following expert installation tips, and avoiding common mistakes will ensure your pavers remain beautifully set and structurally sound for years.
