We feather edge it when wet to get it in to shape then close with a plastic trowel it pretty flat by then and for mono would be left untill scraping, with the CPI we leave it for a while longer then use the Speedskim to get it ready for sponging just like u would a float but you kind of tear it even flatter then it already is.
Its totally different to s+c andy. It works better as a one coat system just like mono. It had be rubbed sooner to get a finish, however can still be rubbed when it gone quite hard if need be. Its like the best s+c you could think of.
we did try flattening off after spraying the CPI with the speedskim and it worked ok.
