All,

The furnace cement done at the factory isn't holding up well. Anyone tried high temp RTV?

TIA

Dave

Don't think you'll find a RTV that is rated up to temps of a coal stoker grate. :|

Somewhere up near 1500-2000, maybe.

Big box stores have a couple brands of cement in small plastic tub and some have it in caulk tubes.

I used Imperial furnace cement from True Value. The stuff had great adhesive properties, sticks well, and great fun to get off your hands. I dampened the cast area first and then spread the furnace cement with my finger, no tools I found worked as well. Run a dampened finger over it, smoothes out real nice. Holds up well. Good to 2100 F.

Our local Home Depot has small (8oz size) plastic tub of Imperial Cement, and it's made in USA. :D

Says 24 hours mine went 12 hours tops and is doing just fine. You know my grates sat there all summer, and guess what it was forcasted for a cold nite and who would of thunk to seal the grates ahead of time :oops: Before work sealed them, and fired up after work with no problem. If it drys and seals as quick as it does to my fingers 24 hours drying time is overkill.
