Are your temps so cold that it will prevent the tree to naturally sap? If you are still in somewhat warmer temps, once you prune some branching your P. abies should sap a little to seal up the cuts. It doesnt look like it should take much.
Just my opinion. There are loads of Norway Spruce in my yard, I just pruned some branches back and they oozed sap. Temps here have been in the 30's and 40's
