A place to discuss aquaponics

Thanks for that Delgrade!

That rocks will have a chat to the hardware tomorrow. See how much it costs and if they can get it in for me.

Ask them to stock "aquarium" grade silcone as well.... for sealing any joins holes etc......

also jamie i couldnt find one called sikatite , the only sikka products i could find were in calking tubes called sikaflex i got a few tubes its safe for pottable water and will seal my patches nicely and its safe for potable water

CHeers and good luck Treebeard

First is cited as suitable for water immersion...

Second as meeting "potable" standards

eeep you had me worried for a minute there rupe

here is the one that i actualy used

Ok... so there's at least two "potable" approved types and one approved for constant water immersion.... wonder what the differences are.... just bonding qualities with different materials I guess

.... thought it was "Sikaflex" that Jaymie had used actually....

I used Sikatite (black goop) for sealing the concrete and steel and I used Sikaflex (grey goop) for joins etc.

When the tank was repaired and the concrete added, Sikaflex (grey) was put across the joins between the concrete and the steel. Then numerous coats of Sikatite (black) was painted on the concrete and steel.

Any small holes in the coro bed were sealed with Flex and painted over with Tite. The whole bed was painted with Tite.

Hi Tree beard

Couple of Crommelins products.

First one Radcon 7 which I have tried. This is unusual in that it penetrates and seals the concrete with a silica hydrophobic barrier. It can be applied with a normal garden sprayer or brush. It will reseal very small cracks as it does not harden. Supposed to be guaranteed for 25 yrs. Given the tanks you will be using this would be my first choice.

Second is elastoseal which I am thinking of using on fiberglass troughs which have cracks in the gel coat (also goes on cement) Dries to a coating like butyl rubber (got some sample strips).

Hi Sleepe and all

Have just printed everything and had a good read. The Radcon#7 Seems to be the better option based on the type of tanks I have so will pop out and get it costed (very small piggy bank, as far as the wife is concerned should probably be stealth Aquaponics:). The Sikaflex may be the go when sealing pipes and plumbing.

Again thanks for the input.

Tell the wife the Radcon is to seal the shower (it will do that as well)

Then tell the wife to take a shower ( a long one) while you check for leaks ......

then nip out and paint the tanks real quick

Nice!!!!

I see I am amoung professionals when it comes to affairs of a domestic nature. Hardware is having to get back to me, a lot of head scratching going on about unfamiliar products and avaliability.

eeeeeekkk!!! need heart medication...

Radcon 7 must be best...8lt is only $640.00 may look for cheaper alternative or just buy polly tanks ...will now lookinto hopefully cheaper Sika products
yikes..

Sorry about that, I personally am into minimal cost but have not bought Radcon for ages. Checked Cromelins over here, quoted me $75 + gst per litre (covers 5 square meters per litre) still damned expensive. Sika is pretty pricy (and good). Have you got a Bunnings store over there? Usually the cheapest. With concrete there are a number of options. My next option would have been one of the Bondall products, but I see they are also in WA.
I suspect all these products are going up here because of the mining boom.
Going to have to leave it to one of the NSW members to advise if there are any manufacturers there. The old way of sealing was with a bitumen paint, but I am unsure of who makes that now.

I got 20L of Sikatite for $125 ? There may be a Sika agent nearby?
