Hello:

Have a bunch of railroad ties that are used for defining the boundary of
some garden
plots. They are black, which I assume is due to Creosole. About 25 yrs of
age.

They are cracking and de-laminating pretty badly, and would be a real pain
to replace them all.

Is there anything I can pour into the cracks to seal them up ?

I realize epoxy would probably work, but it would take an awful lot of
mixing, and a lot of epoxy, to do it.

Anything simpler available with a chance of doing the job ?

Thanks,
Bob
