Like any other sealant or glue job it is absolutely necessary to

I'm going to clean the crack with a pressure washer.

That should clean it well enough, don't you think?




Yes, that will clean it well. It needs to be dry, too, so either wait a
while or use compressed air or a heat gun to dry it out. Some compressors
add a lot of oil to the air which would prevent the sealant from sticking
so check yours by blowing air onto a clean towel.
