I think you're confusing it with another product. It's a polyurethane sealant in a tube like the silicon sealant things, you need a sealant gun for it. Just squeeze it out and use. Yes it does have a limited shelf life - a few months really - and once it starts to go off inside the tube it's had it (I'm finishing off off right now that I had to cut open as both ends had set).
