Can you use this product on birdbaths?

Asked by: gardenlover
Great question! Rust-Oleum LeakSeal Sprays are not recommended for the inside of birdbath since the constant exposure may cause it to peel. It is suitable for the outside of the birdbath.

Can this product be used to seal the water leak coming out from the crack between the lid adapter and the plastic bucket?

I am using the Gamma Seal lid on a 5 gallon bucket. However, the adapter ring to the top of the gallon is leaking water. Will this prodcut work to stop the leak. Will this project work on plastic bucket?

12 oz. LeakSeal White Spray is rated 3.8 out of 5 by 79.
Rated 5 out of 5 by from Rust-oleum Leak Seal Rust-oleum offers a flexible rubber coating in a spray on can. This seals cracks and leaks on a variety of products including concrete providing a water tight and flexible seal. Be sure to read instructions to prepar surfaces correctly. Used the seal product on concrete around pool and skimmer cover. Easier and cheaper than replacing the concrete. Cures to touch in 2 hours and complete cure is around 24 hours. Comes in a variety of colors.

Rated 5 out of 5 by from No more leaks I could not really be more pleased. Over the past few months I've noticed part of my gutter downspout and corner tends to leak after or during a rain storm from spots where they shouldn't be dropping water from. So I snagged some leak seal, after a couple of dry days I got up on the ladder, cleaned the location of the leak and sprayed it on. It went on fast, but I was surprised to see bubbles in the application given the add suggests it goes on smoothly. Thinking, okay it will dry without bubbles I left it. Nope... bubbles hardened and I put a second coat on just to make sure none of those bubbles gives me a leak. (I should mention they are really small bubbles, smaller than course salt size.) But now for the real result, it rained and no more leaks! Very pleased. It is paintable so if my color is not quite right I can paint it, but looks good to me.

While it does seal things up, it doesn't always do it on the first try and while you're using it prepare for it to get all over the place. On you and on almost everything else. Even when I was prepared for it the second time I used it, it still got it on about 60% of stuff I didn't want it on, including me.

The store rep told me they had it. When I got there, I I found something called "flex a dip." which was not what I wanted. So I kept looking and found the LeakSeal. It was a little too watery and I am returning it this weekend.

I had a previously damp corner with minute crack, an inch or two long in my garage. Lightly wire brushed the spot and then covered with Rust-oleum LeakSeal. It adhered to the concrete great. Will use again on other projects of similar nature.
