Help!

I just stuccoed my backyard bbq island. I used La Habra stucco over
wonderboard, mixed to mfg directions. Put 1 coat on about 3/8" thick.
weather about 80F, no direct sun. Now, about 2 hours after installing
there are numerous hairline cracks all over. What can be done?

Is there some sort of elastomeric product to paint it with?

spray light coat of water every few hours so it will dry s-l-o-w-l-y.
not enuf to wash off stucco.
