GREAT STUFF PRO Window & Door 20 oz Insulating Foam Sealant (Fоur Расk, Yellow)

Love, Love, Love. Used this and window on my kitchen renovation in wicked old home. Used a IR viewer to spot cold air leaks and killed them dead with this and the pro gun, which is amazing. With this system you don’t have to use a can up in one session. You can leave this on the gun for a week or so, but clean it well for long term storage or you’ll find yourself dismantling the gun for an hour long session.

These are for use with a dispensing gun i’m a carpenter and I literally have installed hundreds of doors and windows and I exclusively use this system it creates a great air tight seal Locks the units to the framing, it doesn’t expand excessively and cause any bowes in the sides I regularly leave the foam cans attached to the gun sometimes for months at a time and I don’t have any problems with the foam hardening up It works as if I was just using it Essentially the foam doesn’t know that it’s not in the can until it comes out of the end of the gun and is exposed to the airTIP. Whenever I change the cans I make sure to spray some foam just in case air got into the gun during the changeover

I used this about a month after receiving it. The foam came out way too liquidy. I was in my dark attic....after applying it and returning to the lighted part of my home, I looked at the can and found that it had expired a year ago. Seller failed to indicate this. I have very little confidence that it will hold. Wasted money.

Worked great with the hilti foam gun. Screw in style can. This product cant be used stand-alone, needs a spray gun with standard hilti-style threaded coupler

I have used this to fill multiple gaps in and around walls and doors. When paired with GREAT STUFF PRO gun, I've been able to leave the can sit on the gun for weeks and then easily start using it again after one sharp pull on the trigger. Far less wasted product that way. I know a contractor with this same stuff who let his sit for three months and was able to "fire it right up."

This works well and has the lowest price point. Use in your pro gun which is the absolute best way to have great stuff. The disposable cans become obsolete when you buy the pro gun.If you shop well they give away the gun in some sales.

It's super easy to use with the gun. I fill any crack I see. I filled all the cracks around my doors for the winter. Yes, it comes off, but just put more on. If you can feel a draft, just use this. The bottle goes a long way

This combined with the gun is so much better than the can with a straw. There is significantly less waste and you can add a small nose to get into tight spots.
