Here’s how to apply our End Dust™ Magnesium Chloride Flake product to unpaved roadways and other dirt or gravel surfaces. The same method can be applied on a smaller scale to both indoor and outdoor riding arenas.

STEP 1: PREPARE SURFACE

  • The first step is to prepare the road surface.
  • Work the road with a grader into a smooth and consistent surface.
  • If washboards or potholes are present, cut enough to eliminate them.
  • After blading the road, you will have a windrow that can be placed in the middle of the road or down one side.

STEP 2: ADD WATER

  • Bring in the water truck and spray the road and windrow.
  • Apply as much water as you can. The moisture will create a strong binder.
  • After the road is soaked down, move your windrow across the road to reshape it.
  • Try not to overwork the material.
  • Add more water, soak down to the point of almost puddles.

STEP 3: APPLY PRODUCT

  • Apply product with any type of spreader used for sand, salt, or seed.
  • The road should look like it was just fertilized.
  • When the product hits the ground you will hear a popping sound, which means the water content is perfect.
  • IMPORTANT – Do NOT add water after applying product!
  • Keep traffic off the road for as long as possible, up to 12 hours.

APPLICATION TIPS

  • Moisture is the key to the successful application of this product.
  • Each application prep will vary depending on composition of the road surface, the volume of traffic on the roadway, and the soil conditions.
  • For example, a clay base road will not need as much water as a sand base road.
