B1 Fire Rated PU Gun Foam 750ml, 12 Cans, Gun & Cleaner

Great fire rating. (You must check the coding used to indicate how flamable it is. ) needed to get another box for the job. But still made an improvement to sound levels

I get a lot of supplies from my local DIY/trade supplier, so I'm a bit prone to comparing, especially for consumables, and I think on balance this is a pretty good option. When I consider this kit includes an applicator gun and a can of cleaner this actual per can value for fire rated foam is pretty good (and that's before I've even factored in my fuel and time to go into town). The applicator gun is nicely made, and feels sturdy and well put together. The adjustment is good and smooth, and really the whole thing feels like a quality bit of kit, not super premium but very good. The only minor issue I could pick with it is the back side of the trigger has a few sharp edges, but nothing that will cause problems during use. The foam works great, just as expected. I've used plenty of other types of Stick2 products in the past without any issues, and although it's my first time using this foam it seems just as confidence inspiring, so I'm really happy all round. I'd definitely pick this up again when I need some more.

Handy package that has everything you need to fill/fix/grip etc with expanding foam. The included handle/applicator is well made and easy to attach to the tubes. Once in place aim and pull the trigger - best be gentle at first. Also best to apply sparingly at first if you're not used to how much this sort of stuff expands. It's often more than you might expect. Once done be sure to turn the handle over (so can facing down) and run for a few seconds to clear the nozzle out, then run the cleaner through for 10 seconds before storing. If the foam sets in the handle then it's basically scrap.
