Conforms to ASTM C144 and CSA 179 

5.4 MPa (783 psi) at 28 days

Between 5 °C (40 °F) and 35 °C (95 °F) 

Between 5 °C (40 °F) and 35 °C (95 °F) 

220 minutes

Allow the surface to dry for 24 hours before opening to foot traffic, and 72 hours before opening to vehicular traffic.

Longer drying times may be required when temperatures are below 21 °C (70 °F) for the first 24-72 hours after installation of Evolution Polymeric Sand. Protect joints from rain for a minimum of 24 hours. Ensure that any sprinkler systems that are in close proximity to the newly applied Evolution Polymeric Sand remain off for a minimum of 72 hours after installation.

Yield will vary depending on the size of the joints and pavers used.

• Install only in good weather. Do not proceed if rain is expected within 24 hours or 48 hours for joints wider than 13 mm (½ in), as heavy rainfall can wash away or displace the polymeric sand. Cover the surface if necessary.
• Ambient and surface temperature must remain above 5 °C (40 °F) for a minimum of 48 hours after installation.
• Ensure pavers, slabs, or stones are completely dry before spreading sand to prevent sticking or staining. Remove any existing polymeric sand before wetting.
• Required tools: stiff and soft bristled push brooms, leaf blower, vibrating plate compactor, and spray nozzle with shower setting.
• On steep slopes or wide joints, surface water may reduce penetration. Install a small test area before full application.
• Wait at least 30 days before applying sealers or cleaners. Verify compatibility with the paver manufacturer.
• For touch-ups or reinstallation, remove all existing sand to full joint depth or at least 38 mm (1.5 in) before re-sanding.

• Install pavers, stones, bricks, or slabs over a properly prepared surface. Use a suitable bedding mix for final leveling and provide an appropriate drainage base in accordance with ICPI Tech Spec #2.
• Compact installed pavers: Use a plate compactor for interlocking pavers, bricks, or slabs. Use a roller compactor for natural stone. For large or sensitive slabs (e.g., porcelain), compact manually using a rubber mallet.
• Ensure all joints are completely free of excess bedding mix, laitance, or debris. Joints must be empty and clean before spreading the Evolution Polymeric Sand.
• Ensure pavers and joints are as dry as possible. Moisture can cause premature gelling of the product. Plan for at least 24 hours without rain or 48 hours for joints wider than 13 mm / (½ in). Ambient and surface temperature must remain above 5 °C (40 °F) for a minimum of 48 hours after installation.
• Apply the Evolution Polymeric Sand first in a small test area of approximately 0.6 m x 0.6 m (2 ft x 2 ft) to verify proper performance and aesthetic results before full-scale application.

Spreading: 

• Ensure the surface is completely dry before starting. Spread the Evolution Polymeric Sand evenly over the paver, stone, or slab surface.

Joint Filling: 

• Sweep the Evolution Polymeric Sand into the joints using a stiff-bristled push broom, filling joints to full depth while leaving approximately 3 mm (1/8 in) below the paver chamfer.
• Repeat spreading and sweeping if necessary to ensure joints are completely filled.
• For steep slopes or wide joints, install a small test area first to verify proper filling and penetration.

Compacting:

• Compact the joints using a plate compactor over the entire surface. For natural stone, use a roller compactor.
• If mechanical compaction is not possible, manually tamp joints using a rubber mallet.
• Ensure the sand is densely packed and level with the desired joint depth.

Cleaning:

• Remove excess Evolution Polymeric Sand from the paver surface using a stiff-bristled broom.
• Follow with a soft-bristled broom, then a leaf blower to remove any remaining Evolution Polymeric Sand residue.
• This ensures no sand sticks to the surface and prevents white haze formation after watering.

Watering / Activation:

• Water the Evolution Polymeric Sand in sections of approximately 5 m² (50 ft²) at a time, starting from the lowest point and moving upward.
• Use a garden hose or spray nozzle set to “shower.” Shower each section for about 1 minute, ensuring water penetrates at least 25 mm (1 in) into the joint.
• Avoid high-pressure jets or large water droplets that may displace sand.
• For joints wider than 13 mm (1/2 in), do not water more than 5 m² (50 ft²) at a time.
• Use a leaf blower to remove any excess surface water from pavers after watering.

Post-Application Note:

• Water activates the bonding and condensation of the Evolution Polymeric Sand in the joints. Improper sweeping, compaction, or watering may leave a white haze on the paver surface. The haze will dissipate over time or can be removed using an appropriate concrete cleaner.
• Do not use a pressure washer, as it may displace hardened Evolution Polymeric Sand from the joints.

• Allow a minimum of 24 hours for the Evolution Polymeric Sand to cure and harden before opening the area to foot traffic. For vehicular traffic, allow at least 72 hours.
• Curing time will be longer in cold or damp conditions. Warmer, dry conditions improve curing and final durability, especially for wider joints.
• Protect the joints from rain for a minimum of 24 hours. Keep sprinkler systems off near the newly installed surface for at least 72 hours.
• In the event of unexpected rainfall during the curing period, temporarily cover the area with a tarp and remove it once rain stops.

Clean all tools and equipment after use with water.
