Paint question
 

i just finished making a waterfall for a terrerium.. its made from spray foam. i am looking for something that can be constantly wet and underwater... also has to be non toxic.. obviously. any one from a pet store know what they use?

use a marine paint

People seem to use Krylon Fusion in tanks for under-the-waterline spots, so that would be my guess. Around here I've only seen it at Canuck Tire..

I've gotten Krylon at Walmart as well.

I wonder if it will melt the foam much like some spraypaints in the past have melted the styro we use under tanks? This happened to me although I don't recall if I was using Krylon for that application.

Thanks.. I may just email ecoterrera and see what th use on their Styrofoam backing... Thanks to all who replied.

You can actually purchase what is called Pond foam at landscape retailers and some pet stores. It is grey and expands like the foam insulation. It is safe for fish also since it is rated for ponds and no need to paint. I also sprinkle aquarium sand on it to give it more texture.
