What brand is your jelly?
I did an 8x8 shed with a big tub of the stuff from B&Q a little while ago, be surprised if anything would spray it at low pressure, messed about with various rollers but just couldn't get grain penetration and the pigment was really weak, very boring big brush painting in the end and 2 coats!
100m of fence! zzzzzz - good luck staying conscious mate
