Compared to the disposable cans with straws these are much better. The gun orientation makes it easier to use for me including getting into corners. These contain twice the product as those disposable cans and you can actually re use what's left later which is virtually impossible with the other cans. It does require the applicator gun and your also going to want a can or two of cleaner but it's worth it for the reusability.

It works, but we have way too much.

Foam is fireblock ORANGE (which is what we ordered and it should be). Use these cans with reusable foam gun.

Unfortunately, if you don't use the whole thing at once, they tend to leak. *Customer service was quick to reach out and discuss the issue. They were very attentive and I feel they went above and beyond. Hopefully this was just a bad batch.

This is used with a gun and you get a lot more foam for your buck than the individual cans with the little straw applicator. The are fine for a once and done job. If you have to foam a lot, buy the gun. Be sure to buy a can of cleaner of it will ruin you gun after sitting a day or so. Remove the can from the gun. The can will spew out a little foam. Use the red spray cap on the cleaner to clean out the excess foam from the can. Now clean off the excess foam from the gun connection point and the tip. Finally, attach the cleaner can to the gun and spray until clear. Remove can but do not spray out the cleaner left in the gun. It is under pressure and will continue to clean. Store in an outside location as the cleaner will slowly seep out and smells.
