FAQs
Is JBL ProHaru Universal safe for fish and invertebrates?
Yes, the adhesive is formulated to be non-toxic to animals and plants once fully cured.
Can I use this adhesive to repair a cracked aquarium glass pane?
While it can bond glass, it is not specifically designed as a structural sealant for aquarium seams. For critical aquarium repairs, consider silicone sealants specifically rated for aquariums. ProHaru is better suited for decorations and non-structural components.
How long does it take for the adhesive to fully cure?
Curing times can vary depending on application thickness and environmental conditions (temperature, humidity). Generally, it becomes tack-free in a short period but requires several hours for full strength. Refer to the product packaging for specific curing guidelines.
What materials should I avoid using this adhesive on?
You should avoid using JBL ProHaru Universal on Polyethylene (PE) and Polypropylene (PP) plastics, as these materials are not compatible with the adhesive.
Can I use this adhesive to glue live plants like mosses and ferns?
Yes, the adhesive is excellent for attaching mosses and ferns to decorations like driftwood, rocks, or other substrates.
Does the black color transfer to the water?
Once cured, the black color should not transfer to the water. The adhesive is designed for aquarium use and should remain stable.
Can this adhesive be used for pond liners?
Yes, it can be used for sealing minor leaks or bonding compatible materials within pond setups, provided the surfaces are clean and suitable for adhesion.
Troubleshooting
Adhesive not bonding securely
Ensure surfaces are thoroughly cleaned and dried before application. Remove any existing biofilms. Check that you are not trying to bond PE or PP plastics.
Adhesive appears weak underwater
While it bonds underwater, ensure a strong initial bond in dry conditions if possible, or apply to a surface as free of algae/biofilm as possible. Ensure sufficient curing time before stressing the bond.
Tube is clogged
Ensure the cap is securely sealed after each use. If clogged, gently warm the nozzle or carefully clear it with a fine needle if dried residue is present.
Accidental bonding of surfaces
Work quickly. If surfaces bond unintentionally before full curing, carefully try to separate them. For cured bonds, mechanical removal may be necessary.
Pros and Cons
Pros
- Bonds effectively both underwater and above water.
- Non-toxic to aquatic and terrestrial animals and plants.
- Adheres to a wide range of materials including glass, metal, wood, and mineral substrates.
- Suitable for attaching live aquarium plants like mosses and ferns.
- Odorless formula for a more pleasant user experience.
- Black color helps camouflage with decorations and substrates.
Cons
- Not suitable for bonding Polyethylene (PE) or Polypropylene (PP) plastics.
- Requires dry surfaces for optimal initial bonding of biofilms.
- 80ml volume may be insufficient for very large projects.
Setup, Compatibility & Care
Setup:
- Ensure the surfaces to be bonded are clean, dry, and free from dust, grease, or slime. For best results, especially on new materials, remove any existing biofilms.
- Apply the adhesive directly to one of the surfaces.
- Press the parts together firmly.
- Allow the adhesive to cure. For underwater applications, ensure a strong initial bond before submersion. Full curing typically takes several hours, but refer to specific product instructions for precise times.
Compatibility:
- Bonds well with: Glass, metal (aluminum), wood, mineral materials, and most plastics.
- Does NOT bond with: Polyethylene (PE) and Polypropylene (PP).
Care:
- Keep the tube sealed after use to prevent the adhesive from drying out.
- Store in a cool, dry place away from direct sunlight.
- Clean any excess uncured adhesive immediately with a damp cloth. Cured adhesive can be difficult to remove.
