Keratex Hoof Hardener strengthens weak, worn and cracked hooves by improving the molecular structure of the horn itself. Equally effective in wet & dry conditions. Prevents the horn from taking in excess moisture, making it resistant to softening and weakening in wet conditions. This results in a reduction in shoe loss and abscesses. Keratex Hoof Hardener is not an oil or resin layer and does not seal the hoof. Hoof Hardener will ensure the treated hoof is able to breathe naturally. Moisture balance is properly maintained. Should also be applied to the sole of the hoof to prevent bruising.
