DYNA Polymeric Sand locks pavers in place, prevents weed growth, deters ants, and resists erosion from wind, rain, and pressure washing. It also gives your hardscape a cleaner, more refined finish.

The sand should be installed to the full depth of the paver joint, finishing 1/8” (3mm) below the top surface or chamfer edge.

DYNA Polymeric Sand is not designed for vertical installations. However, for small vertical areas, you can mix the sand with water to a cookie dough consistency. Lightly mist the vertical joint with water and trowel the mixture in. You’ll have about 20 minutes of workable time before the material becomes unmanageable.

No. Always remove existing sand to at least 1 inch of depth. Filling joints partially with regular sand can lead to cracking, flaking, and poor performance.

Yes. DYNA Optimax is specifically engineered for overlays. It’s less permeable and ideal for installations over concrete.

Wait 24–48 hours, or until the surface and joints are completely dry. You can use a blow torch to test for hidden moisture in the pavement.

Yes, DYNA Polymeric Sand is suitable for saltwater pool environments.

After installation, wait 24 hours once the surface is dry before allowing foot or vehicle traffic.

Joints should be filled to about 1/8" below the chamfer or paver edge. One 50 lb (22.7 kg) bag typically covers 75–100 sq. ft., depending on joint width and paver size.

Mist lightly in multiple passes, allowing water to soak gradually. Avoid flooding. Ensure water penetrates the full depth of the joint to fully activate the polymers.

DYNA Optimax sands are rain-safe in 15 minutes over a traditional base. For overlays on concrete, allow 24 hours.

If recent, run a sprinkler on the surface for about an hour. If a crust formed, poke holes to allow water in. If it doesn’t harden within a few dry days, the sand must be removed and reapplied.

This is usually due to trapped moisture. Allow more time for drying in warm, dry weather.

When installed properly and maintained, it can last up to 8-10 years. Keep joints clean and free from accumulated dirt or organic material.

Dry areas will harden first. Damp or poorly drained areas take longer to cure. Cold weather may also delay curing.

Cracking is usually caused by paver movement or an unstable base. DYNA Polymeric Sand is flexible but requires a proper sub-base for best results.

Yes. Use a pressure washer, and if necessary, remove and replace the sand in affected areas. Regular maintenance with DYNA Efflorescence cleaner helps prevent regrowth.

This is due to persistent moisture or poor drainage. Use a diluted pool algaecide to help control growth.

This is likely polymeric haze, caused by:

1. Excess sand left on the surface before watering.

2. Overwatering or uneven watering.

3. Insufficient water activation.

4. High humidity or rain shortly after installation.

5. Old or poor-quality sand with excess binders or pre-activated moisture.

No, but it may affect aesthetics. It’s mostly a cosmetic issue and can be cleaned to restore the look.

• Low-pressure washing (1,000–1,500 PSI): Clean the surface without dislodging joint sand.

• Efflorescence cleaner: Use DYNA Efflorescence Cleaner for stubborn stains.

• Mild acid wash (last resort): Use diluted muriatic or phosphoric acid with caution.

• Thoroughly sweep off excess sand before wetting.
• Use a leaf blower to remove fine dust.
• Apply water gradually.
• Avoid installation in humid or rainy conditions.

Installation must occur above 0°C (32°F). Cold temperatures prevent proper curing.

Yes, but clay is more porous. We recommend DYNA Optimax for superior water resistance.

Use a pressure washer with hot water (180°F / 82°C) or boiling water for small areas to soften and remove the polymers.

Score around the paver with a utility knife, remove sand from the joints, and lift the paver. Pre-wetting the area helps soften the joints for easier removal.

Compacting ensures joints are tightly packed, preventing voids that can lead to failure. Use a mallet or 2x4 to tamp down slabs if mechanical compaction isn’t possible.
