thank you so much gary!
so...does this mean i could make 10 slabs say, with just the base coat or even with a scratchcoat, let them dry for however long, and also have large batches of mortar for the browncoats and intonaco coats prepared and waiting for when i am ready to use them? i was always under the impression i had to mix them up fresh for each project...this would save me a lot of wear and tear and from making such a mess over and over again!
and can you mix an older batch with a fresh one, or is it better to keep them separate....
ok! i'm off to find a concrete company! wish me luck!
