Foam Rock Wall

Well it's almost done, just need the epoxy and sand sprinkle to protect the foam from UV. The wall is in two pieces, try and guess where they meet (nutty)

 

Those 2 speaker grills are my screens for the CL

Not worried at all. I've just finished coating the foam (2x) with epoxy and sand. The Pond & Stone is made for water and once it protected it will not dissinagrate. It's the other foam by Great Stuff that is used for filling/insulating holes that is the problem. Not made for water contact.

 

The idea, where else RC

Those are really plastic "grills" and not metal. DOH!

 

Bob - You could do this on one of your display tanks and don't need a rock wall. Did you see my post on "Gluing Rocks"? I used this same foam to "afix" several rock piles together and in one pix I am actually holding one of those piles up in the air. Just an idea

 

AquaticEngineer - Got it at Ace Hwdr, but not all of them carry it and it costs too much on-line with shipping added. I have one full can unopened I was gonna to take back, if you can't find it LMK I'll sell it to ya. It's call Great Stuff Pond & Stone

This one is finished drying, There is no exposed foam for disinergration, there are 2 layers of sand and epoxy so the foam is sealed, on the front on the back side there will be no light so no problem. If there is, I'll just slip a piece of black acrylic in between the tank wall and the back of the foam wall.

 

 

Those are two holes in the upper right corner and not foam, one of the BH's for the CL is showing thru

 

 

It's time consuming, planning where to place the rock, try to have holes for tunnels and use less foam. I've read that even though you may have 20lbs of rock, it'll float like a boat, so you have to use the foam sparingly on the open area's and where there is a "lot" of foam you can cut it out from the backside egg crate and all.

Not sure what you mean by columns.

 

You can only put so much rock on the egg crate - mostly small stuff to look like a rock wall and the foam will be the rest. Or else it'll lean, I use rocks that were kind of flat or had a cup in it and just turned it up, tie wrap it to the egg crate foamed, cleaned, cleared out, then epoxy with sand sprinkled.

 

Also while I use the foam, I sprinkled sand while it was still wet and that worked out. Didn't have to do too much but epoxy and sand.

OK cool, there is an Ace Hardware here by my work in LO. I'll check it out on my break and see if they have any. If not, how much would you want for yours and where are you located?

Ace Hardware in Lake Oswego does carry it. They had two cans left, I grabbed one and theres one still on the shelf if anyone wants it :D

 

I'm going to re-do my terrarium tomorrow with the pond and stone. In the past I have used the regular great stuff and covered it with black silicone, this makes it much easier (clap)

 

I'll post up some pics when I'm done, thanks again for pointing this stuff out.
