Just something brought up over on the plumbing forum. Seemed to be a mix of opinions on whether or not you could add silicone over old silicone, usually to cover cracked sealant etc.
As such I did an experiment to get a did definitive answer.
The first bed was put down and given nearly 48 hours to cure.
After that a new bead was added, firmly pressed to the older silicone and with a decent bed behind it to simulate filling a gap or what have you.
Again this was allowed to dry fully before testing.
On testing the new bead was pulled at to see how easily it came off. Remember that these were new beads and clean unlike silicone that might have been down for years!
And the result?
It came away effortlessly.
So obviously without teaching how to suck eggs, hopefully this will help someone or anyone in the future with either DIY or indeed professional jobs.
Cheers
