Polymeric Sand

Our technicians will re-joint your walk, patio or driveway. We use a next-generation polymeric jointing sand specially formulated to stabilize the pavers while preventing erosion. For many projects, it is a superior choice over mason sand in that it inhibits weed growth and resists ants and other insects. It can last for several years, depending on conditions and upkeep.

 

Polymeric jointing sand is a high-tech mix of graded, colored sand and a binder, specially formulated for the filling of joints between pavers, slabs or natural stones. Unlike conventional sand it stays in place and remains stable. It softens when wet and firms up when dry to better resist soil movements. Because the sand gets stiff you can expect fewer weeds and less insect damage.

You can keep an extra bag of polymeric sand on hand for seasonal upkeep when joints fail. Polymeric sand can be kept in its original packaging, in a dry place and away from UV rays. Bags may be stored outside if they are properly protected with an opaque and waterproof tarp.

Polymeric Sand Upkeep

1. Preparation
Weather Conditions: There should be no precipitation for the next 24 hours. Temperature should remain above  32°F during the 48-hour drying period.
Surface Conditions: Begin with a dry surface to prevent moisture from activating the polymer, which could make sand stick to and stain the surface.
Removal of Failing Joints: Use a screw driver to remove older sand that is no longer maintaining a neat joint.

Surface must be dry. If covering a large area, spread sand uniformly over the surface. Using a push broom, sweep the product to fill the joints completely, down to their full depth. If you prefer, use a small plastic cup filled with sand to direct the product into the joints.
3. Wetting the Joints
Important! Before wetting the surface, remove all sand residue with a leaf blower. Keep the leaf blower at a good distance, so as to not empty the joints. Sand that sits on paver surface and gets wet can stick like glue. Ensure that the wetting of one section is finished before moving on to another section.
1. Set the spray nozzle to “shower.”
2. Wet the section for approximately 30 seconds without displacing the sand.
3. Wait a few seconds and wet the same section again for approximately 30 more seconds to wet the joints completely.
4. Using a small screwdriver, verify the progress of the wetness in the section. The objective is to get joints wet 1 ½” deep.
5. Immediately move on to an adjacent section. Avoid flooding the surface to prevent unwanted run-off.
Tip: On textured pavers, after wetting the joints, use a leaf blower to blow excess water off the surface. This will remove any remaining sand and polymer residue to prevent hazing.
Drying: Drying time will be shorter if it is warm and dry, and longer if the climate is cool and damp. Temperature should remain above 32°F during the entire drying process.
Restrictions Before Use
• Foot traffic is okay right away, but avoid high heels that can disturb joints
• Motor-vehicle area, wait 24 to 48 hours
