will silicone cure underwater?

[fatrip]

just wondreing if any one knows if silicon will cure underwater???

I don't think I'd want to try. Just have patience and wait two days for it to cure.

No, it won't. It won't even stick to the surface initially.

you need it to be dry to stick and the air to help dry

it will cure underwater i dont know how strong the bond will be though, 24 hours is usually good for it to dry

Silicone and water = no.

On the label it says that it puts out toxic fumes while it cures. I would wait.

I had a misshap some time ago...was changing baffles in my sump and was running only on one side. Other side dry and with new baffles being siliconed. Within two hours of applying silicone we had a transformer burn up and I was without power at the worst possible time. Sump flooded into new silicone and I feared the worst with no water made up to do a change with and new silicone drenched, soaked less then 2 hours after application. So I did the best I could do.....nothing. End of story. Fish inverts and corals showed no damage and the baffles were as strong as any other in the sump.

I use silicone in my business (window installation) as long as it is applied dry it will cure in rain. I didn't know it would cure underwater though

you cant apply it underwater obviously but once its on there it will if it is wet
