I never thought of using Drylok on wood.
Neither had I until I read a bunch of forum posts on a cichlid forum. Turns out guys/gals over there have used it directly on plywood and even melamine to make anywhere from 90 to 1100 gallon tanks, although in the case of the 1100 gallon tank it was not applied directly on the plywood. I believe the largest tank over there with drylok directly on plywood is 600 gallons.
And since you already know it sticks to everything you know you can paint it over most anything.
