I foolishly used some old RR ties as risers in a landscaping walkway. With

is there any way to treat the surface of these ties to prevent this?
Tearing up the risers would be somewhere between inconvenient and really
hard.

Visit your materials place and get a bucket of stone dust. Apply a thick
layer of stone dust on the ties while they're hot and oozing. Pretty
much the same idea as the chip seal they do on roads.

If you have a cement manufacturer nearby get a load of "crusher dust,"
the stuff that is produced as a byproduct of Portland cement
manufacturing. I've found that it is a bit better than plain stone dust
for this purpose.
