I have never had much luck spraying glue.
I mix white glue 50:50 (approximately) with water and add a few drops of liquid dish soap. I spray (spray bottle from the hardware store plants section) wet water to fully wet the area to be glued. I then dribble on the glue mixture until everything sits in a small puddle. This works great for ballast and ground foam.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
Jeff,
Well, it should at least cut down on your vet bills. What will science come up with next?!? (Hint: Jeff, this may be a sticky point but...you may want to add an "r" in "spaying" in the subject line to remove any more confusion.)
