I use the pl roofing goop. If put on when clean and dry and let it dry it seals well and holds well.

Just be aware that if you cover the weir with rocks, the water level flowing over it will be raised. That could cause an overflow. Found that out the hard way!

More expensive but GOOP for marine use sticks and dries like a rock. Made to be used under salt or fresh water.
I was going to add the same caution - some weirs are adjustable I believe, but you do want to be aware of this. Also, rocks will trap debris that would flow right over a smooth weir which could cause the same issue.
Just some things to think about! I definitely understand the desire to cover the plastic though.

I used the PL roofing goop on several in-pond projects, and it worked like a charm. Agree with others, though, about using caution.
Wait a minute...are you talking about the actual weir, or the plastic box. Just to be sure we’re all on the same page, a picture would be helpful.

If you are talking about the weir don't do it. The weir needs to be able to float freely. Silicone we'll work.
