Composition & Materials:
JOINT-LOCK SAND is a uniformly blended mixture of top quality mason sand with a polymeric additive. When activated (by water), JOINT-LOCK™ forms a firm barrier — Like a one piece flexible joint. JOINT-LOCK™ will become pliable when it is subject to moisture such as rain or when rinsing with a hose, and will re-harden as it dries, forming a strong yet pliable joint.
JOINT-LOCK SAND, while easy to use, requires a few basic steps to prevent unnecessary clean up or extra work. To create a long lasting paving stone terrace, patio, or driveway, use JOINT-LOCK™ between the paving stone joints for maintenance free enjoyment for years to come. Our fine blend of quality mason sands and organic polymers provide a long lasting environmentally friendly solution to your next paving stone project.
Application Guide – New Installation
1. Clean & Dry Pavers
Make sure that the surface of the pavers and the paver joints are free of debris and completely dry before applying JOINT-LOCK™ SAND. The weather forecast should be rain free for 12 hours after application to ensure optimum bonding and product performance.
2. Pour Sand & Spread
Pour JOINT-LOCK™ SAND evenly over the entire area to be finished. Sweep JOINT-LOCK™ repeatedly over the joints until they are completely and uniformly filled. For best results fill the joints to 1/8″ below the top surface of the pavers. DO NOT USE A FILLER SAND AS IT WILL COMPROMISE THE STRENGTH OF THIS PRODUCT.
3. Compact Sand & Sweep
Use a gas powered plate compactor to compact the sand between the joint of the pavers. this will ensure all voids are filled, repeat steps 2 & 3 as necessary. After compaction sweep off all extra sand. If pavers are coarse, use a leaf blower on lowest setting to clear off the paver surface.
4. Repeatedly Saturate Area
After you have ensured that the paver surface is completely free of sand, lightly but thoroughly saturate the area. (For best results do the saturation in 50-100 sq. ft stages). The objective is to soak the area as deeply as possible in a controlled manner. Using too much water will float the polymer sand out of the joints resulting in deposits on the paver surface. Repeat this step 2 times allowing 10 minutes intervals between soakings. Make sure the paving stones are free of car and foot traffic for 18-24 hours following application of JOINT-LOCK™ SAND.
Clear Weeds & Debris
Make sure to clear all weeds and debris between the pavers so JOINT-LOCK™ SAND will be able to bond to the paver joints.
Power Wash the Joints
Using a gas powered pressure washer clean the paver joints of the existing sand to the full depth of the paver. Let the area dry completely and then follow steps 1-4 (New Installation) above.
Curing and Usage Info
The area should remain traffic free for 24 hours following the application of JOINT-LOCK™ SAND. JOINT-LOCK™ requires very little maintenance after the initial installation. Avoid using JOINT-LOCK™ in areas of persistent dampness (pools) or on sloping grades greater than 5 degrees. If an area needs sand replenishment simply follow the steps above.
