Great Stuff 99108862 Smart Dispenser Window & Door, Yellow

I wrote this same review for the gaps and cracks version, but it applies to the Window and Door version just the same. I've used a lot of both and here's my impressions and tips for using it!I’ve used a lot of these “smart dispensers” now and thought I’d share tips for using it. First of all, after using the old straw for years this new smart straw is awesome. I’m not dripping foam all over the place anymore and I honestly can keep using the same can over and over. (some of my cans have lasted over 30 days by the way).Here’s my tips:Make sure you thread the dispenser all the way onto the valve (see my first photo), like to the point where you start turning the valve itself. Do not unwind it! If you unwind it after you’ve started using it, the pressure in the straw might unwind the straw on it’s own and make a mess. Be aware of that!You can break them. It is made of plastic. The weak point is where the moving straw part meets the part that screws onto the valve. (see the spot circled in my second photo) I think another reviewer showed that same location because it was leaking foam there. That’s because it broke there. It only breaks if you put a lot of force on the end of the straw. If you are going to force the straw into a crack, or are going to press hard on the tip, use your other hand to support the end of straw so it doesn’t tweak that weak spot while you're spraying.In order to get the most consistent bead of foam, I’ve found that if I let up on the trigger slowly at the end of each spray I won’t get a gush out of the straw on the next pull. Letting off slowly releases the pressure in the straw so it doesn’t spurt out on the next pull.Hope that helps. I love this smart straw and I can’t believe they didn’t come out with something like this years ago!

This review would be a 5 star but the tip is too thick for putting it in tight cracks 1/8” of windows. I’ve been putting in my own replacement windows and if it’s a tight gap it’s hard to get the tip in. I did buy same brand at local hardware store with small diameter tip, so I know they make them.HERE IS A TIP first caulk inside of window gap after installing window, if you don’t it could expand to inside of the window and is nearly impossible to remove.Another tip. You do not need to tape window or brick to keep this foam off of it. Take a butter knife and as it expands, and it expands for nearly 15-20 min, burst the expanding foam almost like a bubble and it will keep it from coming out. DO NOT spray this and leave. You will come out and it be all over the window. I made that mistake on the first window thinking this kind didn’t expand that much but it does expand it just doesn’t get as hard as other non window foams. ALSO if it gets on the window plastic IMMEDIATELY wipe it off and it will come off. Paper towel is fine. But if you wait any time at all you cannot remove it. People say you can but you can’t. I tried on the first window and nothing gets this off if you let it stay on there for longer than a few seconds. I have reused cans before by taking off the tips and use the new tip from a new can later on.

I love in a holey old house, and the windows leak horribly in winter. One of them is so bad it definitely needs to be replaced, guess who doesn't have money for that? This girl. So this is a good hold over, so far it's held up in the rain, we'll see about snow. Works like it says it will with the fancy nozzle, I was able to stick it in the siding cracks and fill in a bunch of gaps, I'm probably going to get a bunch more before it truly freezes here.

The can is not reusable not matter what the instructions say. You must use all of the product or risk having half a can you can not use. Must use all of the product in the can all at once. Zero expanding should be just that, this expanded at least once if not more. Filled in the window gap and came back several house later to find it crawling up the sides of the window from expansion....except in the area where I flubbed it a bit, nothing expanded into that space, just all of the areas around it leaving a hole in the sealant layer. Product needs revised instructions and labeling.

I had issues with the foam dispensing very inconsistently. I looked at the expiration date of the can and saw I was sent an expired one. I received this mid February and the can expired in December. I’ve used this product before and had no issues, so this is definitely the result of the expired can.
