Replying to How to make pow ramps less......powdery

Hey Newschoolers, tonight Syracuse received around 3-4 inches of snow yay! Anyways, I went out to build a pow ramp at my campus around 7:00 p.m., and it took me around 3 hours to finish building it. Probably could of hucked a 5 off of it but the best I could do was a 3. I felt I could do better, but since the ramp was so powdery I couldn't really get enough pop and my skis would end up taking about an inch or two off the lip every time I would hit it. So basically my question is how do you ice over the ramp without using salt
Sorry for not search barring it btw, I was just hoping to get more direct answers by detailing my specific problem.
