Thoroughly clean hoof using a hoof pick and wire brush if necessary. Due to the sticky nature of the ingredients you may want to use gloves to apply. Excess product may be removed with isopropyl alcohol. For packing under shoe and pad: Pack hoof sole with magic Cushion prior to nailing or gluing on pad and shoe. For packing overnight: Pack hoof sole with Magic Cushion to a depth of ½ inch. For optimal results, especially barefoot horses, cover sole with paper or plastic, then cover entire hoof and sole with self-adhering wrap or hoof boot. Reapply every 24-48 hours until condition improves.
