Fortunately, I host my pictures through photobucket, not MFK... so yes I can!
The Background in this Vivariums is DryLock. On this one I mixed the color in by hand in small quantities, so I cannot say what the per gallon blend would be... but I added a lot of black pigment.
This is my Tegu when he was just a little squirt. The back wall shows grey DryLock with 2 ounces of black pigment in it...
The esterrior of my 4' x 2' x 2' is painted in Kilz, white with 2 ounces black added. It's not very pretty for 'in the house' but worked great as this cage was built for outdoors or in the fishroom...
As you can see on my vivarium, I am not at all hesitant to add more than two ounces of pigment when using it as a basic sealer. I am building a water container for the Tegu cage I am also building. I've not yet decided if I am willing to add more than 2 ounces for a container that will literally be filled with water 24/7... but I am completely confident in DryLocks ability to make a Plywood 'water dish' 100% water tight with 2 ounces or less added...
If interested this is the design for the water dish... 30" x 12" @ 8" deep...
This is the overhead view of the cage I am building (made my first few cuts last weekend and am on my way out to the shop to do some more when I get off of here)... 8' long x 2.5' deep @ 3.24' tall... will double as a stand for a 125 or 180 gal tank...
