About Rust-Oleum Leak Seal

You might have taken all the measures possible to make sure your house looks in its best shape possible. However there are times when you will notice some cracks and leaks, which can be quite annoying. What’s worse is if they remain unattended, they can lead to much bigger problems at home that can cost you a fortune. Thankfully now you have Rust-Oleum Leak Seal Flexible Rubber Sealant , which will help you get rid of leaks and cracks in the house without any difficulty and before the problem deteriorates any further.



How does Rust-Oleum Leak Seal work

This sealant leaves you with a rubberized protective utility coating, which has been specially created to cover leaks and fill cracks. What’s good about this sealant is that it’s extremely easy to use and you can do the job at home yourself without hiring any professional help. Any gaps and cracks in the house will be filled with a limited overspray, which is a huge relief. Another advantage of using this sealant is the fact that it creates a water tight seal, which doesn’t let any moisture percolate through it. Hence it offers brilliant protection from problems caused due to water penetration, corrosion and rust.

You get top quality results when you use this sealant and the coating doesn’t sag or drip; thus any mess is avoided. When the sealant dries up, you get a much desired semi smooth finish that’s also firm. It’s extremely versatile for use and can be used for exterior as well as interior jobs. Moreover you can use it on PVC, galvanized metal, Aluminium, roofing material, vinyl siding, fibreglass, asphalt, concrete, masonry and many other types of materials. You can also top coat the seal with the help of oil or latex based paints after giving it about a day’s time.

Depending on the surface porosity of course, it gives coverage of about 10 sq ft and much to your delight, the flat finish doesn’t reflect any light. The seal you get is dry to touch in about 2 hours offering you a quick and effective solution.


Rust-Oleum Leak Seal Pros

It’s quite a handy sealant that works on both concrete and plastic equally well. It’s very easy to apply and you don’t have to struggle with coat application for long. Another good news is that it dries rather quickly, without dripping of sagging. No more mess in the house and creating another problem when you are trying to fix one. The semi smooth finish you get with the coat is quite even as well.

The coverage this sealant offers is quite good too and for its price, it is very good value for money. The only thing you need to watch out for is that the sealant dissolves in gasoline. Make sure you keep it away from gasoline when you are using it.


Rust-Oleum Leak Seal Cons

The sealant does work to an extent but you have to be very careful about the angle you are going to spray it in. You could be using it on plastic or a metal surface, if you don’t have a clear shot at spraying then you are going to be in trouble. The sealant will just not work, which is quite disappointing, because no where are you warned about this problem in the advertisements. You often have to keep twisting and turning the can in many weird positions to get the angle right for spraying, which makes using this sealant a very tedious exercise. You might end up wasting a lot of time because of this problem.

  1. I used leak seal only for one project, and now then can will no longer spray. When I shake it, it sounds like there is liquid on the inside so it hasn’t solidified. The sprayer just won’t work. Is there something I can do to get it to function again? Kind of expensive for one use only.

  2. Can we use leakseal on wood? We are hoping we can use it to protect the wood 4x4s that are holding up our porch roof. The very bottom are showing damage from the sprinklers. Thank you.

    • I would use a thinned out fiberglass resin. Thin with 20% acetone, and saturate the wood. It will cure hard as fiberglass, and be waterproof.

  3. I painted the front of my aluminum motorhome with white Rustoleum leak seal because there are pinhole leaks from moisture and corrosion inside. How can I clean bugsplats and stains off the white leakseal?

  4. Has anyone tried to use Rustoleum Leak Seal on a child’s rubber swimming pool. I think we have a very small leak somewhere in the seams…but I want to be sure the Leak Seal won’t burn/melt the rubber pool.

  5. Rustoleum Leak Seal liquid works great when mixed with cayenne powder to fix and prevent rodents from chewing on your electrical wiring . Many rural areas have rats and mice that seem to love chewing the rubber off the wires in barns, sheds , even under the hood of vehicles . Make sure all power is off and you wear rubber gloves , glasses , and a dust mask when mixing and applying mixture !

  6. How do you remove Rust-oleum Clear Leak seal from a aluminum door threshold caused by over spray? The spray turned yellow over night.

    • Try some WD 40 spray , its very mild stuff and wont hurt much of anything. Have a can of insect repellent ? If WD40 didn’t help try any brand of repellent ,use caution with this stuff !! It will dissolve most any plastic and painted surface including fake fingernails or anything painted. Best to spray on an old cotton rag and rub only the affected metal. Amazing what we spray all over our bodys and never think a bit about it !!
