Hello.
I am planning to cast kitchen countertops in concrete. This weekend we did a test casting to check color, texture, etc. The casting was done on Thursday afternoon and the mold was removed on Sunday around lunchtime. The slab was covered with plastic the whole time. When we removed the mold, the slab was still wet both on the top and underside. Everything looks as we expected except that we have gotten light spots on the slab (see attached image). What could this be due to?
We used Finbetong. The temperature when the concrete cured was at most 25-30 degrees, I guess.

It's probably far from dry. Come back in a week or so.
Have you vibrated it, by the way?
