DYNA® OPTIMATRIX Polymeric Jointing Sand is well below the “OSHA’s (29 CFR 1926.1153) limits for construction material. Click HERE to read more about the OSHA’s Silica Standard.


DYNA® OPTIMATRIX Polymeric Jointing Sand is a dry mixture of calibrated sands, polymers, binders and dedicated chemical controlling agents specifically designed to bind firmly and easily together in horizontal pavement joints. Applied dry into the pavement joints, it will harden and stay in place after activation. It sets in minutes after being activated with water, which ensures a proper installation even when the weather calls for early rain. Carefully blended with dedicated control agents, the quality of DYNA® OPTIMATRIX Polymeric Jointing Sand ensures increased stability, performance and lasting durability to your paver projects.

OPTIMATRIX Polymeric Jointing Sand retains adequate elasticity needed to adapt to the movements of the pavement surface. It is resistant to erosion due to weather, maintenance, and traffic. It features "zero dust" EZ SWEEP TECHNOLOGY to ensure no haze is produced on your pavement surface and that the sand is more easily swept in, saving you both time and money in the process. Unlike conventional polymeric sand that requires 3 wetting applications, OPTIMATRIX requires a single wetting, saving you further time.

NOTE: DYNA recommends using the “Highly Water Resistant” DYNA® OPTIMAX Polymeric Jointing Sand for surfaces installed over concrete and for drainage and non-drainage bed installations, including false joints and heavy exposed water areas. Examples of this would include swimming pools or high sloped areas.


- Quick-setting. Sets up in minutes upon activation. No need to worry about early rain washout.
- Low temperature setting. Sets at temperatures at or above 0°C (32°F).
- Incorporates "zero dust" EZ SWEEP TECHNOLOGY which eliminates haze on the pavement surface and makes it quicker and easier to sweep.
- Single wetting activation, saves time and money.
- Excellent for exterior/interior applications.
- For residential and commercial installations.
- Suitable for both pedestrian and vehicular traffic.
- Contrary to regular sands, it stays firm, flexible and perfectly in place after wetting & curing.
- Ideal for most pavement joints greater than 2 mm (1/16”).
- Ideal for use on sloped pavement.
- Eliminates washouts of sand into pools.
- Ensures a better stability of the installed pavers.
- Strongly inhibits weeds from growing.
- Adapts to paver movements in all weather conditions.
- Eliminates joint erosion from rain, water, frost, wind, power washing, and traffic.
- Resistant to freeze-thaw cycles.
- Deters ants and other insects.

DYNA® OPTIMATRIX Polymeric Jointing Sand should be used to fill pavement joints of Concrete Pavers and Slabs, Natural Stone and Clay Pavers installed on horizontal surfaces such as driveways, patios, pool decks, walk-ways and garden areas.
For deeply sloped areas, or for areas that are exposed to heavy traffic and heavy maintenance duties, we recommend that you use the DYNA® OPTIMAX Polymeric Jointing Sand.



Minimum Width of Joint: 2.0 mm (1/16”)
Minimum Depth of Joint: 32.0 mm (1 1/4“)


- Install only at or above 0°C (32°F).
- Installation of the pavement must be done according to the various ICPI specifications to ensure the maximum benefit of this product.
- Do not leave OPTIMATRIX on the surface prior to wetting as it will adhere to the surface and will be difficult to remove.
- Not a substitute for a mortar or cement grout.
- Do not apply to wet or damp pavement surfaces.
- Do not apply if rain is forecasted less than 30 minutes after installation.
- Do not use if the pavement surface is installed directly on concrete or does not have a drainage bed.
- This product is not designed for submersed water applications.

- The pavement surface and joints must be completely dry.
- The outdoor temperature must be equal to or greater than 0°C (32°F).
- No rain should be forecast within the next half hour after installation and activation.


1. Sweep OPTIMATRIX Polymeric Jointing Sand evenly into the pavement joints using a push broom until the joints are completely filled.
2. Remove all sand residues from the top of the pavement, using a leaf blower.
3. Compact sand into pavement joints as prescribed by ICPI Tech Specs., or your paving stone manufacturer’s recommendations.
4. Blow off with a leaf blower all excess sand and any dust residues from the top of the pavement making sure that the surface is perfectly free of all particles.


1. Work in sections of about 10 m2 (100 ft2).
2. Use a water hose equipped with a fan shower head working at low to medium pressure.
3. Starting at the highest elevation of your surface, position the shower head at 0.6 to 1 m (2 to 3 ft) from the surface and shower the surface in a sweeping movement from left to right. Clean the surface rapidly while allowing the water to slowly migrate, absorb and channel into the joints. Continue to water until the joints are thoroughly wet, a good indicator is when you see water standing on the joints.
4. Focus on watering the pavement and not the joints. By doing so, you will remove any fine particles that could have adhered to the pores of the pavement surface. If pooling of water occurs on top of the joints, proceed to wet another area.


Before using this product, always test on a small area 1.0 m2 (10 ft2) of your pavement making sure to follow the instructions carefully. Let dry for 24 hours. If you are satisfied with the results, proceed with the entire surface area.


Depending on the width of your pavement joints, a 22.7 kg (50 lb.) bag of OPTIMATRIX Polymeric Jointing Sand will cover from 3.0 to 10.0 m2 (30 to 100 ft2).
