Casting concrete vessels with GFRC

Hey all , 

I ve been going through older posts but couldn t find any help for casting concrete vessel in gfrc.

What kind of mix design you guys have for casting vessels or farm sinks and how do you proceed ? 

I ve been doing a few pours with an ECC Mix but it ends up that I have some fibers showing... Should I first pour the mix (without fibers ) so it covers  the mold with a thin layer (face coat) and then add the same mix but with fibers ? 

Thanks for your help!

I usually spray a mist coat into both pieces... then... assemble the mold...wait a bit and fill up with a SCC GFRC mix.
