fireproof concrete/patching material for woodstoves?
 
ok, here's one for you fireplace/woodstove guys. i have a real old woodstove that has the inner fireproof cement liner deteriorating. is there a mixable powder product i can use to refill the gaps?

tnkx!

Yes there is and Lowes use to carry it. I believe it is called firecrete. But I am not sure.

Furnace cement, most well equiped hardware stores will have it.

Years ago I had a Jotul Model Number 1 with a cement liner that had broken off near the door. It was a 3" by 8" piece. I used furnace cement to re-glue. It worked well and never came lose, but I did not use the stove extensively so cannot be sure how well it held up. I sold the stove 2 years ago.

I am not sure you can use the cement to seal cracks. Unless you are sure you have the right product, it might be worth a trip to a wood stove outlet store. You will pay more, but can be sure you'll get the right product.

Wood stoves are great, but not worth burning down your house. I'll never forget Christmas Day '05 watching helplessly as the first spreads across my neighbors roof. Cause, yep - a wood stove. Waiting for our awesome volunteer fire department to arrive was the longest 10 minutes.

you are right there dac, i ended up buying a 1/2 gallon tub of 'refractory cement' for repairing firebrick. this is what i believe i needed, the furnace cement says for brick to metal or metal to metal, so i wasn't sure if it would do what i needed. just a follow up so you guys know what i ended up with. though this stuff says i need to apply no more than 1/8" at a time, we don't NEED the woodstove yet, so i can layer it till flat. cool! thanks for your responses and helping steer me in the right direction.

i almost hate to ask (about such a tragedy) but do you know the specific cause - chimney fire - creosote? or from burning a bunch of Christmas wrap / packaging? old / outdated / substandard flue components? over-fired stove box?

not trying to dredge up bad memories, but I too love the wood stove, and if there's a specific thing here to drill into our heads about this, it could save another family from the same fate...

The report I got from another neighbor was a pin hole in the double wall lined pipe where it passed through the roof. Obviously not related to this situation, but just wanted to impart how careful one should be with repairs. We always think wood stove fires happen to the other guy.

I might suggest to the OP to check your work after firing the stove the first time.

no problems here as the work is inside the woodstove. just cracks and wear and tear on the liner is all. first coating all done and it seems to be fine. no work on the chimney/flue except the cleaning yesterday. =o)
