Everyone on the crew swore wetting the surface first gives you a creamier float, but on this pour the water just made the top slick and we got a 20 foot section of delamination that I had to chip out the next morning. I said forget it, dry float only, and the finish came out tighter with no dusting. How many of you actually wet your slabs before floating?
