I have a hip-roofed garrison colonial in New England, with blown-in cellulose. I have two whole-house fans ("half-house fans"?), and to give enough attic venting I have continuous soffit vents on all four sides of the house.
Problem: some of the cellulose has drifted into the soffits and then over the vents, blocking them. I'm going to remove, clean and replace all the vents (ouch), but I don't want any more insulation blocking them.
There's a substantial amount of (useless) insulation in the bodies of the soffits. I tried using a leaf blower to clean one out one of the bays, but cellulose dust exploded all over my front yard. I can push the insulation to the side to open the air path, but I'm concerned it will just drift back over the vents.
Any suggestions on a spray that could bind the insulation together and keep it from drifting? I could just stick a random can of spray paint up into the slot, but that could get messy. I was also considering dilute white glue. I'd have no problem using up a cheap spray bottle, but that would require something quite thin and probably water-based.
