Wood bull floats can be used as soon as the shake has absorbed moisture (indicated by the darkening of the surface). Float just sufficiently to bring moisture from base slab through the shake. Finishing machines with float blades shall be used to “open“ the surface, prior to the application of the remaining one-third of the total specified shake, and shall be used to incorporate this second shake.
