Diy Glue? / Sealant

Actually there is a difference between Aquarium silicone and the regular stuff. Aaquarium silicone releases ethanoic/acetic acid(viniger) as it sets while normal silicone releases ammonia and methanol, the normal stuff also sets faster.

not true, sorry. the difference is simply in the curing agent, the effectiveness or where you use it is not affected. try a caravan or boat shop/dealer. high modulus silicone in 310ml tubes goes for £3.99, only the clear is aquarium safe though. i believe the company name is Hodgson sealants and it is sold as Hifix HM sealant. it works fine, takes 48 hours to cure, lol not a second longer. i just wish they did it in black. i am told hot glue, from one of those guns works well though too.


Hi all and thanks ever so much for all youre advise ... one thing I did do thinking it would be easier is get the Glue gun and the white stivks (Loctite) in the UK
I spent all day and sorted loads of these caves out only to put them in the water and they DO NOT STAY PUT the glue just disolves, wether this is because I am using slate I dunno ... Just a word of advise really .. I was a bit P'eeed.... LOL

So gone back to the good old £10 sealant .. hmmph.. :sad:

but as some here have said there is no reason to pay that much for sealant, a quick set of phone calls and you should get three for that price.
 
You may have used the "wood" sticks... err, for gluing wood. I use the white/semi transparent "general purpose" ones...


Nah, They are Loctite hot glue melt sticks, all purpose white /clear maybe its just a make thing i dunno lol

Thats odd then - NEVER seen a water soluable GP stick ! They are usually just vinyl !

me either, until i looked at the stops on my tank lid. they were glued with a cheap glue gun from ALDI, they are showing signs of absorbing lots of water, some are even soft to the touch and one had fallen away totally :crazy: . perhaps it is the quality of the glue sticks it uses,. but it was quite a shock!
