Avenuebool Aquarium Epoxy Putty is a two-stick epoxy set for building aquarium landscapes, with 7.9-inch (20.1 cm) sticks for shaping rock features and creating underwater structures.

• Non-toxic to fish and invertebrates — use it for aquarium landscaping around aquatic animals.
• Two epoxy putty sticks and two pairs of gloves — knead the putty while keeping it off your hands.
• Adheres to wet and dry surfaces — work with rocks and coral reefs in different conditions.
• Sets in about 15 minutes and fully cures in 45 minutes — plan your build around the stated working and curing times.

Aquarium layouts often need more than loose rocks: joined pieces can form stable-looking terrain and make defined spaces for aquatic animals. Avenuebool putty is intended for shaping and bonding those landscape elements, whether you are arranging a new tank or adding features to an existing layout. The two contrasting putty parts are kneaded together before use, and the included gloves help keep the material off your hands during mixing.

What can I build with Avenuebool Aquarium Epoxy Putty?

Use Avenuebool Aquarium Epoxy Putty to join aquarium materials into features such as steps, caves, cliffs, and walls. Its adhesion is intended to hold landscape pieces together, including rocks and coral reefs, so you can create varied terrain for aquarium animals to explore. Once cured, the bond is described as long-lasting.

• Shape the layout around the rocks and reef pieces you want to join.
• Apply putty across the joint and press it into gaps and crevices.
• Spread some material along the sides of the joint as well as through the center.

How do I mix and use the putty?

Cut off the amount you need, then knead the gray and black parts together thoroughly by hand. The putty is not prone to flowing, which helps you control how much you apply while working on a joint or structure. Professional tools are not required for the described mixing process.

• The exterior is gray and the interior is black.
• Wear one of the included pairs of black gloves while kneading.
• For the strongest bonding and cure, work in a dry environment and let the putty cure completely before placing it in water.

How long does it take to set and cure?

Avenuebool Aquarium Epoxy Putty hardens in about 15 minutes and reaches full cure in 45 minutes. After one hour, the cured material can be sanded or painted, giving you a finishing option for shaped landscape details.

• Allow the full curing period before putting the bonded piece into aquarium water.
• Use the approximate set and cure times to plan when to shape, finish, and place your landscape feature.

What materials and aquarium setups is it suitable for?

The putty is designed for freshwater and saltwater aquarium environments and is also described for bonding fiberglass, wood, metal, and various plastics. Its stated resistance to high-temperature and high-salt conditions supports use across those settings; the supplied information does not give a specific temperature range or material compatibility list.

• The set contains two epoxy putty sticks and two pairs of black gloves.
• Each stick is 4 ounces (113 g); the set is intended for aquarium landscaping and other listed bonding tasks.
• The product is described as non-toxic to fish, invertebrates, and aquatic plants, and as not releasing harmful substances into the water.

Avenuebool Aquarium Epoxy Putty suits aquarium keepers who want to bond rocks, reef pieces, or other compatible materials into shaped tank landscapes, as well as users working with the listed materials beyond aquariums. It is a practical fit for building defined structures such as caves and cliffs, with gloves included for kneading and a full cure required before water placement.
