Moving forward, it is time to review these products to choose which one you need.

Rust-Oleum LeakSeal Spray

This rubberized coating comes in a spray form that locks away any holes and cracks. The Rust-Oleum Leak seal spray leaves the coated surface water-tight with a paintable finish and is excellent to use for:

  • PVC
  • Masonry
  • Concrete
  • Roofs
  • Gutters
  • Ductwork

How to Apply?

Ensure the area is well-ventilated or outdoors, and apply when the surrounding temperature is 50ºF-90ºF, and the humidity level is below 85%. If you ensure these conditions, it will ensure proper drying and optimal results.

Shake the bottle vigorously for one minute, and make sure you hear the mixing ball rattling. If it doesn’t, DO NOT force anything and contact the Rust-Oleum team.

It is suggested to test spray on a carboard to get the hang of it. Then hold the bottle 20cm to 45cm away from the surface and spray.

Two layers of spray will suffice for proper coating, but keep in mind to wait 30 minutes between each coat. If you want a thicker coating, then spray from a closer distance.


This product has succeeded in pleasing its customers as they deem it durable, easy to use, and greatly adhesive.

From being used on a gutter seam, concrete yard fountain, or other leaks, Rust-Oleum LeakSeal spray and on the hearts of its customers, becoming a 4.5-star product.

Rust-Oleum LeakSeal Brush

If you want your sealant to be in paint form, then Rust-Oleum LeakSeal Brush should be your go-to. Even more so, this product is excellent for filling in areas that are hard to reach, so if you think the spray can’t correctly coat the crack or hole, grab a brush and seal them all.

How to Apply?

Pre-application, you would have to ensure that all the external factors like temperature, humidity levels, and outdoors are the same as those for spray.

As for the actual application, do not shake the container and open it gently. If you wish to stir the paint, do so with a wooden stick and gently to not trap any air bubbles. Then dip the brush in the product and paint over the holes or cracks. Make sure to not brush over areas that are drying up.

Leave the coat to dry for 30 minutes, and then apply one more for longevity. If you feel like two coats aren’t enough, go for more.


The customers also seem to like this product, claiming that it is easy to use and its viscosity does the job. However, some seemed to like it a little less than the Rust-Oleum LeakSpray as it has gotten lower reviews on durability, adhesion, and value for money. The customers said that it dried so fast that you must be standing atop the stop that needs to be fixed, or the seal will dry.

Rust-Oleum LeakSeal Self-Fusing Silicone Tape

Suppose your damaged area is not a surface but rather a hose, water pipe, or an electric wire, then this self-fusing Silicone LeakSeal tape is a perfect choice. Having no adhesive that may melt away with heat and time, this tap is made up of self-fusing properties, creating an airtight barrier.

This product can be used on:

  • Leaky hoses or water pipes
  • Damaged or exposed electrical wires

How to Apply?

Compared to the products above, LeakSeal tape can withstand temperatures as low as -65ºC and as high as 260ºC.

You must tightly wrap the tape around the damaged area and prevent air bubbles from forming inside. Once you have properly wound the video together, the rest will do on its own.


This product has been highly rated for its ability to bear extreme temperatures and excellent adhesion. However, not many people go for this as their first option, and those who do claim that it does exactly as advertised. The product seals any water-leaking holes within pipes and sustains high water pressure.


Rust-Oleum has a great range of products with different application methods to accommodate your area of worry.

After reading through the reviews, which Rust-Oleum Leak Seal do you think is better? We believe that Rust-Oleum LeakSeal spray is the best option as it has excellent reviews for being durable and easy to use.

But, bear in mind that at the end of the day, the product’s application also depends on factors like roughness and porosity of the substrate, loss of material during application, and size of the leakage. The product may act differently depending on these factors, so choose after assessing your surface correctly.
