Bondit Aquarium Sealant – Black, Clear & Grey

Bondit Aquarium Sealant is a marine-grade silicone sealant built for serious aquatic and reptile builds. Available in black, clear, and grey, it covers the colour requirements of most vivarium and aquarium construction projects without compromise on performance.

What It's Built For

Formulated for bonding, bedding, and sealing glass in aquarium construction, this sealant is equally at home in reptile vivarium builds — including flat-pack and custom enclosures. It's also suited to in-situ gaskets and seals for pumps and pipework where water ingression must be prevented, and works as a dust and weatherproofing seal for cabinets in challenging or external environments.

Material Compatibility

Bonds reliably to a wide range of substrates commonly found in reptile and aquatic builds:

• Glass and ceramics
• Anodised aluminium
• Primed metals and timber
• Many plastics

Performance Properties

This is a non-shrinking, non-slumping paste — it stays where you put it during application, which matters when working on vertical joints or detailed builds. Once cured, it is unaffected by UV, ozone, and salt water immersion, and holds its integrity across extremes of temperature.

Choosing Your Colour

Select the colour that suits your build from the options on this page. Black works well against dark backgrounds and rimmed aquariums; clear keeps joins discreet on open-topped or display builds; grey suits metal-framed enclosures and industrial aesthetics. All three variants share the same marine-quality silicone formulation.

For keepers who take their builds seriously, Bondit Aquarium Sealant delivers the reliability and material compatibility needed for watertight, long-lasting results — whether you're constructing a new enclosure or resealing an existing one.
