Leaking floor heat need sealer

[JIMT]

We have a floor heat that is leaking antifreeze but we can't find the leak. We tried an infrared camera with no luck.
I remember seeing in the Forum someone had used a particular brand sealer that sealed his leaking floor heat. I cannot find it on the Forum now. If anyone knows about this sealer or another on that works please let me know.

"Fix A Leak" brand worked for me...I think going on two years now. Bought it at a local pool supply company.

We used fix a leak a few years back on a floor heat leak with good success.

Is this still working for you ?

We used something by the name of "Tub-0-gold"...I think. I believe it was for use with swimming pools. My leak was too large but it did slow it down.

I have a small leak in my floor system.
I just ordered Fix-a-leak. 8oz. bottle.
Do I just add it to my expansion tank and let it circulate?
And hope for the best?
thx
