Very interesting day. The person who does the spraying should definately be prepared. Cover hair, skin, and any clothes you plan to keep. I will be going for a hair trim after this adventure, but the bulk of the insulation is up! wooo-hooooo! None of our helpers had insulation stick to them as I did.. so it's safe for the rest. I would recommend masks for all though.

Two things to keep in mind with this spray insulation. First, a board foot is 12"x12"x1". Our frame, on our 1988 eagle is 1.5" in depth. Keep this in mind, and order material accordingly. Another lesson we learned while doing this task was about the nozzles tips of these kits. The fan tip really spreads the material thin, and looks smooth (but makes a bigger mess). Although it says it expands 8 to 1, that is not so with the fan tip. We did the first wall with the fan tip... after 3 passes, it seemed to have enough to consider the area done. With the fan tip, hold the nozzle close to the intended spray area, and move it slow. With the blow tip, move faster, and hold the nozzle a little further away for best results.

The pic on the left is an opening we didn't need insulation in, using the fan tip in the area around this space left quite the mess. The pic on the right is using the blow tip in the areas around this hole. Much cleaner. The blow tip really is more direct. The second wall, with the blow tip, took one pass, and filled up the space adequately.

Here is my very own invention - a hand saw that cuts flat. Grabbing the handle, and the end of the saw made the saw cut with a curve, that tended to gouge the insulation a bit. With this new saw handle, the saw can remain flat while it cuts. The next picture is Art using the belt sander. After knocking the big stuff off, this works good for getting a level surface.

Now here is something that is not a waste of time!
