it's a it's a powdered dry oil additive that you can add to any dry oil mud that you like to use and it changes the mud so that after you put it on you don't have to wait for it to dry completely and sand it and add another layer you can continue to add layers as soon as it firms up so you don't have to sand between coats and make dust and because of that you can finish probably two days
