{Collins} Re: 811-A Help



Larry........ I see our local builders supply house, Menards, is advertising 
"Black Furnace Cement", a smooth, non-gritty formula which is advertised to 
withstand 2000 degrees F. temperatures....... 10 oz. tube for  $2.46. It is 
made by Rutland.

I have not tried it, but it may be something you should look into for the 
loose 811A base problem, if you haven't found a solution so far.

Let me know if it works for you.  Good luck.
