I am a newbie DIYer and am putting in a 16ftx14ft patio of 12"x12"x2" concrete paving stones over a concrete slab that was laid two days ago.
1. How soon can I safely lay the paving stones, using 1:8 Moist Mixture?
2. How long will the Moist Mix take to dry or set?
3. Will the end result be that I cannot remove the concrete paving stone from the Moist Mix by hand after it has set?

Thank you.

1, a day or 2
2 depends on how moist it is, 5 days is usually ok but if the mix is too dry it will remain brittle.
3 if your mix isn't wet enough the paving will not adhere so a neat cement, sbr bridge bond will be required for adhesion.
