Rated 5.0 out of 5.0 by memcc Wear gloves! Try to use all during one session.
The cans are a little expensive, but they are great for filling up the required space to prevent fires from spreading. Do NOT get it on your hands/wrist/clothes.. or you will be sorry. Wear those recommended gloves!!! I can attest that Krud Kutter is best to take out on the hands ;) though you will need a scrubby or something to get the job done totally. (I followed that up with Working Man's Hands and the result was awesome - can't say the same for the clothes)
I say to use all during one session because you will lose some if you leave it in the can or in the nozzle for the next session and it is pricey. Overall, though, very good!

Rated 2.0 out of 5.0 by HAWG07 Works like the other spray foams
I'm not exactly sure what the advantage is for buying this over normal spray foam. According to the lable there isnt any difference in fire proof or retardency - they are all flamable.
Had I paid more attention, I would have purchased the normal spray foam for a little less money.

Rated 1.0 out of 5.0 by PamQ Messy & wasteful
I used Pestblock to stop honeybees from getting between the siding and wall of house. The screw-on applicator quickly became clogged and the sticky foam came out in gobs that would not stay in place. Luckily I think there is enough in the one spot where the bees were entering that it might accomplish the job, but I am greatly unhappy with the product. The applicator straw, after having to use a coat hanger wire to clear the clogs, broke and the canister is more than 1/2 full of liquid, so you probably should make it in smaller containers and state on the label it is a one-use item. What a messy, wasteful product!!!!!!

Rated 4.0 out of 5.0 by homedoer Great Idea
Good invention, but needs refinement. Is very messy to use, (wear gloves)and hard to control output. My greatest dissatisfaction is wastefulness. a lot of overshoot, but also can not save material in can for another application , nozzle and spout plug up. Need to invent a can that can be reused another day .

Rated 3.0 out of 5.0 by SteveJ Works good for its designed usage
The product information can be misleading if you are unfamiliar with the Building and Fire Code requirements for this type of material. This product is for RESIDENTIAL COMBUSTIBLE FIREBLOCK usage only. DO NOT use for penetrations of Commercial Fire Stop Systems where the Fire Barrier/Wall must be maintained to its designed rating. Polyurethane foam products ARE combustible even after "drying" into a solid foam and therefore can not be used as part of a required Commercial Fire Stop System. The appropriate Fire Seal or Fire Caulk should be used. Make absolutely sure you are using this product appropriately, DO NOT ASSUME.
