Customer Questions & Answers
-
Question:
What is Instant Ocean HoldFast Epoxy Stick used for?
Answer: Instant Ocean HoldFast Epoxy Stick is primarily used for bonding and repairing aquatic materials in aquariums and marine environments. This fish-safe epoxy provides a strong adhesive that cures underwater, making it perfect for securing rocks, coral, and decorations in your aquarium. It’s especially effective in marine setups where traditional adhesives might fail. For instance, if you need to attach live rock or fix cracks in a tank, this epoxy stick is a reliable choice. -
Question:
Is the HoldFast Epoxy Stick safe for fish and other aquatic life?
Answer: Yes, the Instant Ocean HoldFast Epoxy Stick is formulated to be completely safe for fish and other aquatic habitats. Its unique formulation ensures that there are no harmful chemicals that could leach into the water. This makes it an ideal choice for aquarists looking to secure their underwater structures without compromising the health of their marine life. You can use it confidently in both freshwater and saltwater environments without risking toxicity. -
Question:
How do I apply the HoldFast Epoxy Stick?
Answer: To apply the Instant Ocean HoldFast Epoxy Stick, start by kneading the stick until it becomes a uniform color. Then, apply it directly to the surfaces you wish to bond, ensuring a firm connection. It can be used above or below the waterline, making it versatile for various applications in your aquarium. For example, if you want to secure a coral structure, simply apply the epoxy to the base and press it firmly against the chosen surface until it sets. -
Question:
How long does it take for the HoldFast Epoxy Stick to cure?
Answer: The curing time for the Instant Ocean HoldFast Epoxy Stick is typically about 1 hour for initial set and fully curing can take up to 24 hours, depending on water conditions and other factors. This quick setting time allows for convenient repairs without long downtimes in your aquarium. For example, if you're rearranging your tank decor, you can finish your setup within a few hours and observe your aquatic life adjusting to the changes. -
Question:
Can I use the HoldFast Epoxy Stick for dry applications?
Answer: Yes, the Instant Ocean HoldFast Epoxy Stick can be used for both underwater and dry applications. It’s particularly useful for making repairs or creating structures that do not require water immersion during the initial bonding phase. This flexibility makes it an excellent choice for both aquarists and DIY enthusiasts. For instance, you might want to prepare aquatic decor before placing it in your tank, ensuring it adheres properly without being in the water. -
Question:
What if I'm not satisfied with the hold of the epoxy?
Answer: If you're not satisfied with the strength of your bond using the Instant Ocean HoldFast Epoxy Stick, it could be due to application methods or surface preparations. Ensuring surfaces are clean, dry, and properly prepped can significantly enhance adhesion. If needed, you can reapply the epoxy after thoroughly cleaning the area. This is especially important for aquarium structures that are subjected to movement or the force of water flow. -
Question:
Does the epoxy have an odor when applied?
Answer: Instant Ocean HoldFast Epoxy Stick is designed to be low-odor, making it suitable for indoor and aquarium use without creating unpleasant fumes. This allows for comfortable application even in closed environments like a home or office aquarium. Users often appreciate that they can work on their projects without a strong chemical smell, which is common with other adhesives. This makes it ideal for aquarists who often perform maintenance tasks in their living spaces. -
Question:
Is the HoldFast Epoxy Stick reusable?
Answer: No, the Instant Ocean HoldFast Epoxy Stick is designed for single-use applications. Once you knead the epoxy to activate it, the entire stick should be used for that particular project. This ensures you get optimal performance and bonding characteristics. If you have leftover unactivated epoxy, it cannot be stored for later use. It's best to plan your projects to maximize the use of the stick during its effective duration. -
Question:
How does the HoldFast Epoxy Stick compare to liquid epoxy?
Answer: The Instant Ocean HoldFast Epoxy Stick offers distinct advantages over liquid epoxy, particularly its ease of use and control during application. Unlike liquid forms that may require mixing and pose a risk of spilling, the stick form allows direct application without mess. It’s ideal for securing coral or decorations where precision is crucial. Additionally, it avoids issues associated with spilling or running, especially in an aquarium setting. -
Question:
Where can I buy Instant Ocean HoldFast Epoxy Stick in Australia?
Answer: You can purchase the Instant Ocean HoldFast Epoxy Stick from Ubuy in Australia. Ubuy offers a convenient platform for finding various aquarium supplies, including this reliable epoxy stick.
