I cut a hole in the wall... now what?

Yep. I should'a done that or one of the others. Being the lazy soul that I am, I chose to go with the foam idea. I thought it'd be quick and easy. However, Murphy lives in my house and the results were FAR from pleasing. I lined each hole with wadded newspaper, sprayed the foam inside and sat back and waited. After 1 hour, it was still squishy. After two hours, the center had begun to dissolve itself. After four hours of waiting, I started to cut around the edges with a hacksaw blade only to find the entire center had dissolved into one big sticky gelatinous mess. EPIC FAIL. I followed the directions on the can but obviously, there was something important I missed. Of course, I did both holes at the same time so I've got a big sticky mess X2. I'm hoping that if I give it some more time, it will eventually dry and I can salvage what's left.
