[Archers] Spray Foam Target Problems

[JAY NARDONE]

Lord Mungo, yes. This is how I make the insides of our lollipops and this spray foam needs air to cure properly. I have filled bottles as you did and also noticed that if I tried to fill the cement paper tubes too quickly (all at once) the centers would actually never cure and even months later be like that epoxy goo you described. I love the spray foam for targets as it is cheap for a can and I can fill 2 8-10" lollipop targets with one can. You just need to do half and wait a few minutes and then come back and do the rest, sometimes the little tube will clog and you just have to spray right from the can to finish but it will still work. Getting that stuff on you is not fun either, if it gets on your clothes they are done as nothing will get it out! I alos ran over a can of it in the garage and my car still has some on the exhaust pipe as I could never get it all off underneath!

One was "Great Stuff Big Gap Filler", made by Dow and sold only at Lowes. The other foam was a similar Dow product, maybe the same stuff in a different can (also from Lowes, but apparently sold other places as well). I no longer have a can of this stuff, so I don't remember its name, but it comes in a yellow can.

My drill came out covered with a sticky goo similar to epoxy that quickly expanded and solidified. Apparently some bottles had pockets of foam that had been cut off from oxygen and so couldn't expand, perhaps the cans weren't shaken enough, or whatever.

I still use the foam to patch blow-throughs and other weak spots in my flat archery foam targets (made from closed cell ethylene). The foam there is applied in smaller quantities, and is fully expanded and dry in a few hours.
