hundred pounds of sand, about 6 to 8 pounds of petrobond powder, and oil is about a pint if that much. then the Catalyst if your using petrobond I if using petrobond II it isn't suppose to need a catalyst but you know how that goes.

if its close and you can buy ready made thats you best bet, if you have a muller to handle it with cause your not going to remix it by hand like you can greensand. optimum time in the muller for good working sand is ten to twelve minutes. for mixing new sand it takes around 20 to 30 minutes to get it all blended and mixed.
