Description

Substrates, feeders, other supplies, live plants, and educational resources all in one place for convenient pet ownership. Conservation Through Captive-Breeding Passionate About Pets & People One-Stop Shopping For Success Our goal is deliver insects and plants that are alive on arrival in all weather! In 2004 by Joshua Willard made fruit fly cultures for his personal dart frogs. As a way to support his frog hobby and to better serve others in the amphibian hobby, Josh started selling the fruit fly cultures, as well as supplies for kits. Josh's Frogs brand products are made by pet owners for pet owners. Every product is first used in our own facility. Wild animals should never be taken out of their home to become pets. Josh's Frogs is dedicated to changing this. 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. 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. Be careful not to pull the trigger all the way, or else you'll end up with too much foam and a empty can! Foam can also be covered with coco fiber, peat, or sand to give it a more natural appearance. Before the foam is dry, gently cover it in the desired texture and press it in. Or if you want to apply after drying and carving, use a black silicone. After 12-24 hours of curing, this product is safe for both live plants and animals. How much background does this product cover? One can covers approximately 2.5 ft2 depending on how thick or thin it is applied. This is roughly an 18"x24" background. Remember, no need to make the background below the substrate line! Can I construct the background outdoors? While this can be done outdoors, make sure the temperatures are between 60°F and 80°F and your project is not in direct sunlight. Extreme temperatures can cause expansion and curing issues. Can I construct the background indoors? While this can be done indoors, make sure you are in a well ventilated area; it is smelly before it cures.

Great expansion
Number of Items: 1
I've used foam sprays for many projects, but this one is by far the best. At first I didnt think it would expand much, but after letting it set, it looked amazing. Really gave good depths and looks so real. Will be buying this from now on for my terrarium projects.

Good product
Number of Items: 1
I think the product workers very well and is easy to shave and mold as you need. I did a my own background for my new frog tank and while it started off looking a little rough it looks nice when you get to put it all together. Will buy again for other projects as they come up.
