Processing temperature 20-35°C; always preheat MB 12 when using in cold weather. Squirt 16 ml activator into MB 12 special bottle (preferably with a syringe) and shake strongly or mix for 10 sec. Immediately pour the mixture into hoof. When using a pad, cut a 14 mm hole into the pad, remove screw cap from bottle and pour MB 12 directly into the hole. Set time (20°C) approx. 60 sec., colder working condition prolongs set time a little.
