Ratings & Reviews for 3M Fire Block Foam 12-oz Straw Indoor Spray Foam Insulation Canister

Fire block

Never can use it all. Very messy. not all foam comes out of the can.

Fire Block Foal Insulation

Excellent product for sealing behind light switch plates.

Fire block sealant foam

Great stuff, Filled the void perfectly. No problems

Hit n miss with different cans.

1st can was worthless didn't stick at all 2nd can was great. 3rd can again a complete flop. I reccomend that this store stop getting this and get the similar item made by great stuff which was what I wanted in the first place.

Fills the holes

This works as intended. I used it to seal wall penetrations into the attic before insulating the attic.

3M Fire Block-- Refurbished fireplace door panels

I read directions,shook the can as instructed, and proceeded to fill my 2 inch wide fireplace door cavity tracks only 1/3 of the way full because the product states it expands 200%. It also states that it can be cut after about an hour, so therefore I waited over 2 hours and upon cutting to trim I discovered the foam had a hollow area of unexpanded foam running virtually the entire length of the trim strips.

works with help

works great but needs humidity to work better in thick spots. spray some water around the area first

"Fire Block" Foam Unusable Can

I bought 2 cans of foam. One can put out about 1/2 of the normal "YELLOW" non expanding foam can. The other barely got the foam out before stopping. IF I hadnt needed "FIRE BLOCK" I would have preferred the foam in the yellow or red can. I think because the product is a specialty item, sold in the paint department, tucked away in a hole, the turnover of the product is very slow. Thus the cans sit and go bad. The product itself seems very good but unfortunately it totally depends on the dispensin...

Fire Retardant Spray

It is spray for filling gaps with Fire Retardant. I think it is good. I havent seen it during the Fire. Easy to use

3M Gire Block Foam

This product is perfect for sealing up cracks in your firebox. It can prevent a nice, warm, over-sized fire in your fireplace from reducing your shack to glowing cinders! Nothing like a fire inside the walls of the old home place!

Fire stop

Great product to cover gaps between walls and ceiling. Recommended.

Caulk of the town

ok product, does what it should. I do not want to find out if it truly is fire retardant though. Would really like the $ for doing this review though.

Straight to the point

Works exceptionally well in an industrial, commercial kitchen setting for small cracks and holes that would other have the owner tear down a wall to patch the hole. Especially like the fact that it’s specifically designed for fire proofing smaller damaged areas.

More than neeeed

Need smaller cans ... wasted 3/4 of a can ( not used)

Easy to use, and works great
