Tbh i just don't know. I have some silicone on order for a prospective full reseal. But I figured i would try a patch while everythings still in new condition and see if it works in the meantime. I was kinda on a roll with this build, leak stopped me in my tracks, had to try something.I thought silicone wouldn't adhere to cured silicone?
Or is this okay due to the "freshness" of it?
The duct tape was just there to hold the piping in place while it cured. Everything is sealed with silicone.Oh while you are at it. I would fix the pluming. not sure the duct tape is about but from my experience you really dont want and chance of water leaking. even if its a slow leak or drip it could cause lots of damage over time.
hope that did not come off mean or sounding like an ass, just looking out for a fellow fish geek
2-3 days. This stuff cures a lot slower than off the shelf silicones it seems.How long are you going to let it cure before testing it?
That is an idea. I did clean the area with acetone prior to patching it, but didn't apply enough of it to do all that. Worth a try if this doesnt work though i think.One thing you might want to try is scraping the silicone where it leaked and carefully ever so carefully use acetone to thin the surrounding areas. Should stick since it will be in a gummy state.
That is my experience with bath tub silicone sealant and fixing leaks. Just a thought.
I have used some different sealants to fix a numerous list of issues.That is an idea. I did clean the area with acetone prior to patching it, but didn't apply enough of it to do all that. Worth a try if this doesnt work though i think.
from my -limited understanding- I believe most large tank builders will wait a cpl weeks or more to get a full and strong cure.2-3 days. This stuff cures a lot slower than off the shelf silicones it seems.
Ive had some success with partial silicone patches but also failures. One of my garage tanks, a 150, is holding strong for 6 months now with a patch i put directly on top of the old seal. So i know its feasible, but not something i would recommend as a permanent fix.I have used some different sealants to fix a numerous list of issues.
Another thing that just hit be is a new age automotive grade sealant. They make stuff now used on BMWs that supposedly can handle mach 3 speeds. Yet to be tested but sounds like it could handle the pressures you're looking at. Might be concerned with melding into the existing material.
