Ideal for demanding sealing tasks requiring durability and non-toxicity.

## Description

For bonding bedding and sealing glass in aquarium construction.

Ideal for use on glass ceramics anodised aluminium primed metals and timber and many plastics.

Review: Brilliant Stuff - I upgraded my tortoise vivarium and after looking at reptile forums it was recommended to use this silicone sealant. It was so easy to use, creates a perfect seal, holds decorations perfectly. Only downside is that the smell is awful, took a few days for the smell to dissipate but would definitely use it again for non urgent projects.
Review: Perfect for Sealing Bulkhead - Easy to apply and good consistency - it does take a while to go off, which is nice as it leaves plenty of time to go over and neaten up with a damp rag. I was skeptical of using black sealant on a white/grey boat, but it does add a nice contrast as long as you are neat.

## Features

## Questions & Answers

**Q: Will this product adhere to slate   ?**
A: We made a pleco cave with slate and HA6 Translucent . It lasted 7 years in our Discus tank at 30c before the first bits started to come apart. We have just taken it apart and are planning of rebuilding it using HA6 again.

**Q: Will it stick to a preformed hard plastic pond?**
A: Difficult one to say as it entirely depends on the type plastic. It would not stick well to polyethylenes or polypropylenes, but may be ok with certain types of PVC. Bond It recommend you do a test patch in a small area to check adhesion to this kind of surface before using it fully.

**Q: Can this be used on ldpe pond liners please?**
A: I would look for a special bespoke glue for a pond liner, not a job to be done twice.

**Q: Will it stick to pond liner**
A: Not to rubberised liners. Excellent for building and resealing glass aquariums/ tanks.
