Get The Most Out Of UltraShield® EX

Better Application, Better Protection

  • Apply enough product to be effective, which is about 45 sprays (or 2 ounces of product) per application. The coat should feel damp but not soaked.
  • Apply to a clean horse so the spray sticks directly to the hair, not to mud or dust.
  • Shake well before you start applying.
  • Cover the entire hair shaft by brushing the hair up before spraying, then brush down for even coverage.

Pro Tip

I like to spray stall walls and around feeders to

discourage flies from gathering. Spray inside

your horse trailer prior to loading horses to ensure your horses are comfortable while traveling. Apply a light spray to brushes prior to grooming, resulting in consistently full coverage as well as gaining a polished clean hair coat.
