i mix my coco with the glue until it is a nice, thick slurry. if i feel it is too thick, i cut it with more glue. i paint it on with acid brushes Oatey Acid Brushes (3-Pack)-3071020 at The Home Depot i find they are small enough to reach all the nooks and crannies and are inexpensive enough to be disosable. i wait 48 hours or more before applying more. on my final coat i sprinkle a "secret mix" on the wet stuff. you can dust it with coco, peat moss, whatever you like to achieve your desired effect. my mantella tank took 3 coats i believe. take your time, and the result will be well worth it. oh, and i let the final coat "cure" for 3 days or more.
