Bond It BDHA6BL HA6 Marine Silicone, 310ml, Black

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.

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.

I have used a lot of this for projects at home. It’s waterproof, but not the best I’ve used. It has a strong hold and is flexible. It’s cheap for what you get.

Did the job is one application fast delivery very good product. 10/10

I used this silicone to repair an aquarium, very easy to use. Followed the instructions on the tube and once fully cured I filled the aquarium back up. It has been up and running for weeks now and the silicone has been spot on.
