Before you get started, make sure to read all of the instructions and watch the short how to video for best application practices. These application instructions apply for DOMINATOR Polymeric Sand.
1 Pound Sand: .5-1.75 square feet (intended as a sample)
13 Pound Sand: 8-32 square feet
45 Pound Sand: 20-80 square feet

1. PREPARE &TEST
Pavers and slabs must be installed according to ICPI Tech Spec #2 (www.icpi.org) before DOMINATOR POLYMERIC SAND installation. We recommend the joint width to be between 1/8th of an inch and 4 inches and the joint depth to be at least 1.5 inches. If prior sand is in the joints, remove as much as possible before installing DOMINATOR Polymeric Sand. For all paver surfaces, and particularly around in-ground pools there must be a slope of 1/8 inch (0.3 cm) per linear foot away from the edge of the pool, or structures to ensure optimal performance of the product. Do not apply if the paver surface is damp or wet, as it will cause DOMINATOR POLYMERIC SAND to prematurely activate and will lead to the polymers sticking on the paver surface. Damp or wet paver joints will prevent the DOMINATOR POLYMERIC SAND from properly filling into the joints and obtaining very densely packed joints, which is critical to the product’s performance. Temperature must be above 50°F (10° C) for at least 48 hours following installation for proper curing. Keep container tightly closed before and after use to ensure product integrity. On residential and commercial projects, test the product on approximately 25 sq. ft. (2.3 m2) and have it approved by a site supervisor on commercial jobs or the homeowner for residential jobs.
New Paver Installs:
First, spread and sweep product uniformly over the surface. Surface must be dry. Using a push broom, sweep the product to fill the joints completely, down to their full depth. Avoid sweeping the product over long distances, so that its integrity is preserved. Joints must be filled up to the bottom of the pavers chamfer, or at least 1/8” (3 mm) below the top of pavers. Lastly, sweep off excess product from the paved surface with a hard-bristle broom ensuring as much sand is removed from the surface as possible. Use a leaf blower to remove all remaining DOMINATOR POLYMERIC SAND residue from the paved surface.
Existing Paver Surfaces:
First, remove existing joint material prior to installing DOMINATOR POLYMERIC SAND. Second, use caution not to alter the integrity of the underlayment or paver base material. Once all old/existing joint material has been removed, follow the installation process for new paver installs.
Set the spray nozzle to “shower”. Work in sections of no more than 9 sq. ft. at a time. Start showering from the bottom of the slope or the lowest part of the job. Apply water to each section for approximately 5-30 seconds for the first watering (see chart below) without displacing the sand, ensuring wetness throughout the joint. Wet the joints and rinse the residue off the paver surface simultaneously. All residue should go directly into the paver joints. Wait a few seconds for the water to absorb into the joint and then apply water to the same section again for approximately 3-15 more seconds. Stop showering if you see foam or when you see water retention on the paver joints.
Attention: Avoid excess watering of the joints as this will cause sand runoff and a decrease in the sand’s performance. Allow sufficient time to complete the project in one session. Use a leaf blower to remove any excess water remaining on the surface of the pavers. This blowing action is necessary to help remove any remaining DOMINATOR POLYMERIC SAND residue left on paver surfaces.
Can I apply sealer immediately after placing sand between the joints?
With our DOMINATOR Polymeric Sand, we recommend a short waiting period after installing the sand before sealing. You want to ensure that no sand has been inadvertently left on top of the paver surface. If you seal immediately after installation, then you’ll seal the sand into the paver.
Does the sealer lock in the sand?
Yes, our color-enhancing sealers are joint stabilizing. The advantage these sealers offer is hardening the joint sand with a crust on the surface, which will not come out of the paver joint under typical rain conditions. When pressure washed, the sand can be removed and refreshed when re-sealing the pavers in a few years. Click here to view our color enhancing sealers.
Should I re-sand each time I re-seal?
This is optional if the interlocking nature of the pavers is still intact. If pavers are loose, re-sanding may be necessary. If pavers are tight, you may not need to re-sand, and it becomes personal preference.
How do I make sure that I water the sand in correctly?
If you over water you will see the polymers from the sand "floating" out of the sand. If you under water, you will see the top layer crust over and this will not allow the water to reach the remainder of the sand. This will cause a wash out once the top crust layer has cracked.
