Blow it out with a can of compressed air.
Yes. It does not matter if the wall or the window is new or old. It will fill up holes or cracks. If you want it to look nicer after you apply it, then make sure you wipe away the excess as soon as you apply. It dries quickly and it is very sticky, so I suggest you use a old rag or rags.
Not that I am aware of.
I would keep it way from dishes. A mouse will chew right through this stuff.
I would recommend a silicone sealant; it would be a more effective watertight sealant.
Generally I use a utility knife or razor knife to cut foam flat across top and side making it even with walls or corners then sand smooth primer n paint.
Dear LDV18: Good question, but all versions of Great Stuff are VERY flammable -- even when they have "Fire Block" on the label. All versions of Great Stuff -- and similar canned spray foam from 3M -- will ignite at just 240 degrees F. This is significantly lower than the ignition temp for paper or wood. So Great Stuff and similar products will ignite FIRST. Canned foam is banned in commercial construction for "fire stopping" -- e.g. sealing holes in framing around pipes and electric lines. It is used in residential construction only due to a gap in the code. Your local inspector can 'approve' your use of canned foam. Informed inspectors can also fail your inspection, forcing you to spend lots of time digging foam out of holes, then filling the holes with real fire resistant sealant. On a recent project the inspector walked through, smiled and said, "You avoided a costly rework job. Many contractors still use that orange foam." To fire seal, e.g. around penetraions in framing for electric lines and plumbing, use true fire resistant caulk, e.g. 3M Red Fire Barrier CP 25WB Plus Sealant, Model #CP25WB+10, Home Depot Internet #100166701, UPC Code #051115116384. For larger gaps, pack them with rock wool then cover the rock wool with 3M sealant. I hope this is helpful. Mark
I can't understand this question.
Yes it can be reused, but you need to clean the straw out immediately after you are done using with a long piece of thin wire. It won’t get it all out, but it will allow you to use it again.
I would say that it would help. It is a very light foam. I’m not a mouse expert, but they could theoretically chew through it. It would be worth a try in my estimation.
