OK guys, I apologize for keeping you guys in suspense so much more than promised. Ive just been swamped recently and honestly, working on two tanks is soooo much more time consuming than just one... especially since I dont want my main one to lose out....
Anyways, a huge update this time.
To foam the wall, I found some styrofoam (lol so much foam) to prop it up on so that it doest get glued down to the ground
This is the stuff I used to foam the wall
I highly recommend wearing latex gloves because this stuff does not get off your hands for days
This is the tube the foam is dispensed, but luckily for me, the seal was broken and it would just squirt out the side... so I had to put the foam in my hand and dab it all over the eggcrate
after a little, it started to foam out of the tube, and I began applying it that way, here is the end result
Close Up
I noticed that the spots that I applied by hand did not create as round of a foam and had a more realistic look, so the big "boulders" had to go
I used an X-Acto knife and my fingers to cut up and rip off all the big pieces
and also to clear up the rocks a little, which got swallowed up by the foam
The extra foam I took off
So back to try again, I used the foam and sprayed it into my hand (with gloves) and dabbed it on the parts where I picked off the foam. I also sprayed the back sides of the wall to get it more sealed.
QUICK TIP: if you use a water spray bottle and spray the foam while its drying, it speeds up the curing process and keeps it from expanding as much.
Compare the back where I left it alone
And the front which I sprayed with water
