Geocel worked fine with alcohol prep and wet finger. Should've stayed with it. Alcohol is easier to work with, it evaporates slower and stinks less And, - I did let it evaporate before applying Dicor.
Ok, will paint thinner do as mineral spirit then? This the closest that I can get to, in rural Mexico.
Won't do wet finger next time. Btw, Dicor is not THAT self-leveling to produce same results that wet finger does. It just flows easier than a typical urethane caulk (or Geocell). You put Dicor thick and ugly, in waves - and it will remain that way.
