Application: Floating the Finish Coat
Floating finish coats is normally done with a green sponge float. You can combine the two processes of applying and floating by spreading stucco with a hard sponge float. You can spread the finish with a trowel over a moistened brown, and using the edges of the float, open the pores of the finish. You can spread the finish over a dry brown and use a fine mist to bring back moisture into the finish, floating as you mist. Misting the whole surface does not create the streaking and float marks you occasionally see in float finishes.
You can spread finish, double back with another coat and establish an even plane with minimal variations in the base coat telegraphing through during critical light conditions.
Floating with a steel trowel or with a plastic float is another process when applying a synthetic finish.
