Clear Silicon Sealer

[Cayman]

We have 2 concrete waterfall bowls in our pool. The company that made them used a clear silicon around the scupper to seal it. It seems that the silicon that they used, wasn't very good, as they have redone it twice now, but it continues to leak after a few months.

That being said, what is the best product that I can use for this? Prefer something that smoothes like a silicon or caulk to keep it nice looking.

Thank you in advance.

Show us pics of the water bowls, scuppers, and the problem area.

What does the manufacturer of the water bowl or scupper recommend to do?

Hi. Silicone sealant will stick to anything....... Except cured silicone. Or another way to put it would be, nothing sticks to cured silicone.
A fair bit more cleaning might be required before you try sealing again.

Correct... I would remove the old silicon and put something new on it. I am just trying to figure out what would seal it the best and last the longest.

This is what we use for roof / wall penetrations. Stays supple for a long time. I use it at home.

Here are a couple of pictures. I think you can get the idea.

Hi Cayman. That's a situation I would use something more permanent - like a 2 part epoxy bond.

Boss 802, Novagard 700 Series, or 3M 5200. Haven't used them for this application, but should hold on better than the normal silicone. Definitely would clear as much of the old stuff out of there before application though.

Do you know of a good one that I could try?

Hi. I've only ever used Araldite and a sika product, because I only use small amounts so I just get whatever is appropriate from the hardware store. I see epoxies are available from stone suppliers that are suitable for outdoors and set clear. That's what I would look at.
