Can this product be applied when the temperature is below 32 degrees?

Can this product be applied when the temperature is below 32 degrees?
Asked by: Charles
I bet you can, as the leak seal developers claim it can withstand low temperatures. Maybe it will take longer to dry. ( It a woman's, mine, opinion LOL)

Can this be used to seal ABS drain pipe?

Asked by: Blmar10s
Rust-Oleum LeakSeal Flexible Rubberized Coating is not recommended to be used on ABS plastics or synthetic rubber. These two substrates have been proven to be extremely difficult to properly accept coatings.

Does this come in a red color ? want to use on a aluminum valley of a roof.

Asked by: flyboy
Rust-Oleum LeakSeal is available in black, aluminum, white, brown and clear. It is a paintable finish, perhaps you would like one of the red color options we offer to go over the LeakSeal for your finish color.

I am very pleased with the durability and how its sticks to everything you use it on. I used it for my car and sprayed it on over Bondo, Fiberglass and rust spots it fill all little imperfections and dries smooth and looks great. I recommend it for use on what ever you need to seal. I do suggest that it should come in other custom colors on the shelf.

Plashed a little while spraying. 12oz is a little small amount. You go through a can rather fast. I used it to reseal around flashings on roof where vents come through. Easier than using a bucket or can of tar.

Rated 5 out of 5 by from Outstanding Product Had a small leak under my bathroom sink. With one quick coat the leak was no more! That was two weeks and still holding strong.

Rated 4 out of 5 by from Solution for temporary fix of roof leaks. The Leakseal spray was used for a temporary repair on a two square foot section of damaged garage roof. It was easy to apply and seems to be working well since we had 2" of rain in the last two weeks and the repair has held the water out. Since we plan to replace the roof next year this seems to be the best and easiest method to keep the water out.

Rated 1 out of 5 by from Leakseal vs FlexSeal This product just does not seal well and is messy to work with. I have used FlexSeal in the past and Leakseal does not even come close to stopping a leak. I would suggest to Home Depot to consider carrying FlexSeal again.
