Hi There,

I'm planning on creating my very own 3D backdrops made in fibre-glass resin.. These will be super detailed realistic settings that will look completely unique from anything seen before. The idea I have to enhance the look of our tanks hasn't as yet been tackled;)

The question is... what do the big manufactures of backdrops use? I'm a sculptor whos familiar in re-creating objects in resin so the building and molding part would be simple... its Just I need to know if resin is safe with aquarium fish or does it need ti be sealed... Also what kind of paints should be used?

Thanks guys

Phil
 
Here is where live animal testing comes in ;)

Seriously though, there are plenty of options. Just order some and see what other people are making...
 
For the 3D backgrounds bought at stores over here, it would seem they are made from some type of styrofoam or something, and then coated with a hard clear coat and then painted, or maybe its painted then coated...

Sorry can't be of more help, but maybe that can be a starting point?
 
I think it's called G5 pondsealer. Its a clear overcoat that is designed for ponds and aquariums. Search on ebay for it. My friend used it on his concrete 3D BG, to stop the pH going up.
 
I should also mention i think in the DIY section there is a thread or two on making your own 3D backgrounds which might also be of use?

Thanks guys... I will look into all of this :)

If you are using an acrylic resin then you shouldn't have to seal it once it cures. It technically turns into an inert form of plastic. Texture and tint your resin beforehand to help you in the coloring process.

G'luck!

So something like a two part Polyurethane resin will do? Maybe filler it to give it extra weight and thickness?
 
Commercial manufacturers use fibre glass with pva as first layer directly on the rock face to make moulds from.
The actual cast would be a open cell 2 part spray polyurethane foam
First few layer being mixed to rise little and subsequent layer s thickening up.

Hand painted and then sealed with a sealer.

That really sounds like the biz... I'll be starting on a 7ft by 2 ft background soon for my own tank and who knows... it might be the start of something ;)
