Looking great! How long does it need to cure between coats? And about how long is it taking you to apply each coat? Does it dry a different shade? I'm wondering how hard it will be to know where you've applied the 2nd coat, and/or if you've missed any spots. And lastly, how many coats are you going to apply?
There's no curing time required between coats. The CORRECT process of applying Permadri product is to layer thin coats until you achieve the desired thickness. In my case, 60 mil (thickness of two credit cards).
I'm indoors, so I don't believe there's any difference to how it dries in shade. It dries pretty fast, so I wouldn't suggest applying in direct sunlight.
There's a difference between dry and cured. It will be dry to the touch with a little tackiness within minutes, but until it is down to 15% moisture content it is not fully cured. It is water-based and cures by evaporation. This may take up to two weeks depending on weather, humidity, temperature.
I'm applying 15 gallons which was the recommended amount for my project. Each gallon covers 20-30 sq. ft. with the appropriate thickness. I have 300 sq. ft., so going conservative end 20 sq. ft. per gallon, 15 should be just enough.

Sad day today, I lost my long time aquatic friend, my fat sleeper goby. She was very old and died during the night. I was hoping she'd have a chance to swim in the big tank.
