resurfacing fire bricks

PostBy: kweis On: Fri Feb 22, 2013 2:26 pm

Can worn fire bricks be re-surfaced? I've been seeing threads on refractory putty, mixtures, and the like and was wondering if any of these products can be used for re-surfacing older worn bricks that are still solid but have some erosion on them. Any thoughts on this appreciated.

Regards, Kevin

lost cause... the extreems of a firebox I think would reek havok on the re-treads and make it seperate (the curing, moisture content, age, type of mix, etc. will all be working against you).
Ive never personally attemted this but i really dont have to in order to know its just not wise. im sorry :(

It's probably cheaper and easier to replace them. $9 at any hearth/fire place store and I'm sure you can get them at some plumbing supply houses.

Not easy to replace. They are custom sizes. Stove is 1930's Germany. One day I'll have to have them replaced with custom cut bricks. Just trying to stay that off for as long as possible.

You can probably get some of the silica refractory material and use it to parge the the inside of the stove. You can also use it to make a completely new lining for your stove with minimal effort. If there are no replacement bricks available for it, this is the best route to take.

A guy I know had an old German coal burning kitchen range with water jacket that was in dire need of fire bricks. They were odd configuration to fit around water jacket he looked all over for bricks with no luck. When he had his oil fired boiler cleaned he asked the service guy for advice. The service guy lined him up with a couple of pails of refractory repair cement, when they got done it was a beautiful job. Service guy said most important was to create expansion joints in same place the original bricks met, they used thin strips of wood between the recreations of bricks when stove was fired up wood strips burned and space was there. I believe it is still going strong with the hand made replacements.

What do you mean odd sizes? If you have a saw with a tile cutting blade you can cut the fire brick to the size you need.

duck, thanks. Sounds like an option worth trying. Iof, the firebricks are fluted on the side. Not to say the new ones would have to be though. There is a firebrick that fits under the top of the stove with a hole bored through it for the small removeable stove plate on top. Never seen firebrick under the tops of stoves before but this one has it. And another firebrick with a hole in it that fits around the exhaust pipe outlet. The only unlined part on this stove is the grate.
