About This Product

Josh's Frogs Vivarium & Pond Build Foam is perfect for constructing backgrounds and filling voids in terrariums, vivariums, paludariums, and ponds!

This UV resistant foam expands to fill gaps and cracks, small or large, and is easy to use with the included straw applicator. The black color is ideal for uses in which appearance is a factor—much more desirable than the typical off-white foam you may be used to seeing. It also holds up well in both arid and humid environments!

  • Easy to use
  • UV resistant
  • Foam color: Black
  • Great for vivarium & paludarium backgrounds, ponds, & waterfalls
  • Fully cures in 12-24 hours
  • Safe for animals and plants once cured
  • Coverage area: For backgrounds, ~2.5 ft2 

TO USE: Ensure surfaces to be foamed are clean and free of debris. Apply foam in thin layers, allowing 12-24 hours for foam to dry between applications. Foam can then be carved to desired shape. Foam can also be covered with black silicone and coco fiber, peat, or sand to give it a more natural appearance.

This product is a game changer!

Reviewed on May 28, 2024.

This black foam looks fantastic in my tank. The color is consistent, and it looks good. After the foam hardened, I used black silicone on top and added a layer of coco fiber to make a nice-looking background. The foam does expand a bit more than I expected, if it's your first time, I recommend trying to spray some on a paper plate before jumping in too quickly.
