In this video, we explain smooth finish stucco and hairline spider cracking? I don’t advise smooth stucco finishes anymore.
Why? Two smooth coats of a fine stucco finish on any exterior stucco basecoat will usually crack?
Why? They are applied with Portland cement finish stucco.

This video does indeed show the smoothest stucco finish? However, there are issues with this finish; see this to understand why we only apply smooth sand finishes.    • Smooth stucco  

Unlike our Portland cement, which expands, swells like a bullfrog, then the dam breaks, and blam, spider cracking over 99 percent of the wall, if you look super close.
If you apply fiberglass mesh netting to the entire home, the stucco finish may take still hairline or get spider-checking with the first rain or damp weather.

If you really wish for a smooth stucco finish on your home.
I advise hydrating the basecoat for at least two weeks while moist curing it.
That means using your garden hose and saturating the walls down so that they no longer hold water so that the water runs off the walls.
Do this about 5 times within the two-week curing time.
Why? The rainwater or hose water will make the stucco swell or expand, and then when dryer conditions return, they will hairline or crack.
This assures the best one can do before the final application of the smooth stucco finish.

As the first rains, the dual finish will expand, and then when the curing begins, this finish is sealed because of the steel trowel. Thus, hairline or shatter or spider cracking will occur.
This has nothing to do with the proper applications or hydration of the base coats.
