BOND IT BLACK HA6 RTV Silicone Sealant Marine Aquarium Safe Water Fish Tank Adhesive

Bought it many times and never let me down. Used for bathroom and in fish tanks- works well in both.

Bought this product to repair and build up I order to raise pond water levels, it adheres very well also you can smooth out to blend in nice product for quick repairs. Have bought another tube as stock. It’s also user friendly if you have fish. I left the repair 24 hrs before topping up with water also the finish is a flexible rubber feel so moves with temperature of the weather and water won’t split ,

Great item for the price. It is suitable for many areas including aquariums. As others have mentioned use in a well ventilated room/ take regular breaks between applications etc. I found it easily dispenses from the tube, and spreads nicely (not to dense- easy to work with) I have personally found it is rather greasy in texture not a problem but note that for area of work/ hands. Although found it easier to clean up than other sealants. Would recommend highly, but would say tube is limited on information, such as dry time is not on the label. So some research is required but seemingly 48hrs for full cure is the universal advice for areas deeper than 2mm.

This sealant is superb quality & the only one we buy

Excellent stuff. Have used it in the past to make fish tanks.So thought it might be good enough to put between the new (ply wood) sides of my trailer & the steel frame. The sides are bolted on as well, but this has stopped all ingress of water & stuck very well. I'm so pleased I've ordered another 4 tubes. Got some on my clothes & hands - should have worn gloves, as after 5 days of washing them, there is still some on my hands, eek. It doesn't come out of clothes either. Smells a bit like vinegar (acetic acid); the fumes take your breathe away, so always use in a well ventilated area / workshop or preferably outside.

Good

Brilliant product for those who need a powerful fixing in a poor substrate like thermal, light blocks use in modern houses. Must be used with the correct fixing bolts.

I used this to make 2 x 9 tube hides for my group of yoyo loaches. Bonded very quickly to the plastic pipes. To finish these off I will use the silicone to bond a piece of slate to the top and bottom of both hides. This is the only silicone I use now.
