A hoof sealer can help feet that have tiny surface cracks caused by continual moisture changes, similar to what happens with chapped, cracked hands. Hoof sealers keep external moisture from damaging the hoof, keep internal moisture from evaporating and counter the environmental effects on hooves, such as alternating dryness and dampness. 

A good hoof sealant can protect the hoof, but you may have to try several products to find one that works best for a particular horse’s feet and conditions. Follow label directions for proper application and frequency of use, since various products contain different ingredients that affect the tissues in different ways and some stay on the hoof longer than others. Some can be toxic to horses or humans if used improperly.

Sealants should only be used on the hoof wall…
