E-Marco 400 set time

[Gort]

The rocks I'm working with - Caribsea Moani - are too large and heavy to build a full aquascape outside the tank and try to lift in. Plus, I have a somewhat smaller access port cut in the integrated tank lid. They stack together fairly solidly but I want to insure no avalanches, so I'll go ahead and cement them in-tank. Approximately how long will E-Marco 400 take to set firmly?

If you are doing it dry, it takes about 30-40 minutes (in my experience) for it to harden. Then about 2 hours for it to be solid. They suggest 24 hours for full cure time on their website.
