Reduces Arena Dust and Watering

Slow Dust™ is a dust control product that reduces watering and improves the performance of your footing. Slow Dust™ uses a flocculation polymer to bind microscopic dust particles back together. The dust particles floating in your arena are charged to a negative state. Water connects the polymer and dust particles in a network, making them heavy and no longer airborne.

Slow Dust comes in a 55 lb. bag. One bag covers 15,000 square feet

How Slow Dust Works

Slow Dust™ is a flocculant and is safe for horse and rider. Flocculants are commonly used in drinking water treatment plants to bind bacteria, viruses and protozoa enabling them to be removed from the water through filtration. Slow Dust™ can add a bit of traction to your arena because of the particle stabilization qualities. Moisture will be retained and the need to water your arena can be reduced by 50%. Keeping the treated sand moist will help keep the sand particles flocked and out of the air. Easy to install, and maintain. Ratio is 3.5 lbs per 1,000 s.f. for up to 3” of sand.

Flocculation: Dust particles become connected through a polymer network, making particles heavier so they don’t become airborne.

Organic materials in your footing (like sawdust, leaves, manure, urine, etc.) will decrease the effectiveness of Slow Dust because of pH balance. If you are unsure, send us a sample of your sand and we’ll test it with Slow Dust for free.

Slow Dust™ can be used with almost all footings including:

  • Crumb rubber
  • Cotton-added
  • Geotextile*
  • Silica sand

  • Clay/sand mixture

*We’ve noticed a 50% reduction in water when used with geotextile footing.

Application Process
Slow Dust is extremely light and can blow away on application during winds. Choose a calm period to apply.

1. Moisten footing slightly if dry. Minimal moisture is all that is needed. a. If the footing is very dry, the product will fall through the footing to the base and be difficult to activate. b. If the footing is too wet, it is more difficult to mix the Slow Dust into the footing.

2. Groom the top surface 1.5” deep. Spread Slow Dust on your arena using a handheld broadcast seeder or large rubber tire push spreader. SET TO SMALLEST HOLE. DO NOT OVER SATURATE. Not to exceed 1.5 grams per square foot, or 3.5 lbs. per 1000 square feet.

3. Water surface after spreading; do a heavy watering but do not over saturate and create puddles.

4. Let the product work its way in to the footing for the next 12-24 hours. Do not walk or ride on surface for 12-24 hours.

5. After waiting period, water lightly the and then groom at a shallow depth, not to exceed 1 1/2”. Keep the surface slightly moist; do not let it completely dry out between watering. Slow Dust is bio-degradable and requires small amounts of water added on a regular schedule.

NOTE: Groom or harrow to a maximum depth of 1.5″ for the first 2 weeks. Keep slightly moist; do not let it dry all the way out before adding water again.
