Turbo Poly Seal Vs. Flex Seal

Turbo Poly Seal

Overview of Turbo Poly Seal

The Turbo Poly Seal is a water-based sealant that has a paste-like consistency. A variety of surfaces can be coated with it, including metal, wood, plastic, and concrete.

Seals created with Turbo Poly Seal can withstand harsh weather conditions and extreme temperatures. Once it has fully cured, it can also be painted over.

Overview of Flex Seal

The Flex Seal, on the other hand, is a rubberized spray coating that comes in a can. Various surfaces can be treated with it, including metal, wood, plastic, and fabric.

With Flex Seal, you can create a flexible, waterproof barrier that can withstand harsh weather conditions and extreme temperatures. In addition, it is resistant to UV rays and can be painted over when fully cured.

Comparison Between Turbo Poly Seal and Flex Seal

When it comes to waterproofing projects, both Turbo Poly Seal and Flex Seal are popular sealants, but they differ in a few ways.

Method of Application

There is a significant difference between Turbo Poly Seal and Flex Seal in the application method. A brush or roller is needed to apply Turbo Poly Seal, which is a paste-like substance. The process may take a little longer if the surface is large or irregularly shaped. Flex Seal, on the other hand, is a spray-on product that can be applied much more quickly.

Coverage and Price

Both Turbo Poly Seal and Flex Seal are priced similarly, but their coverage areas vary depending on how they are applied and how thick they are. Make sure you read the product instructions carefully to ensure you have enough product to waterproof the surface.

Aesthetics and Texture

The texture and appearance of the finished products are also different between these two products. The texture of Turbo Poly Seal can be slightly textured due to its thicker consistency. On the other hand, Flex Seal dries to a smooth, rubberized finish. Additionally, Flex Seal comes in a wide range of colors, making it easier to match it to your surface.


Turbo Poly Seal and Flex Seal are both designed to last a long time. Flex Seal offers greater flexibility and is better suited to surfaces that may move or flex, whereas Turbo Poly Seal is best suited to surfaces with extreme temperatures. However, both products can resist harsh weather conditions and water damage.

Can Turbo Poly Seal Be Painted?

It is possible to paint over Turbo Poly Seal once it has fully cured. After the sealant has dried completely, you can paint over it with a paint compatible with the type of surface you have sealed. After curing, it is recommended that the Turbo Poly Seal be painted with a protective coating (oil-based paint, silver coating, or aluminum asphalt coating) 24 hours later.

Is Flex Seal A Permanent Fix?

The Flex Seal sealant is a popular and effective solution for a variety of leaks and cracks. The specific circumstances of each application determine whether it is a permanent solution.

Flex Seal provides a permanent solution to minor leaks or cracks by creating a durable and waterproof seal. Additionally, it resists peeling, cracking, and fading, making it ideal for roofs, gutters, pipes, and more.

However, Flex Seal may not be able to provide a permanent solution for larger or more complex issues. Identifying the underlying cause of the leak or crack is crucial in these cases. In order to prevent further damage, additional repairs may need to be made, or damaged materials may need to be replaced.

Last Opinion

When you want a thicker, paste-like substance with greater control over the application, Turbo Poly Seal is a good option. With Flex Seal, you will get a smoother, more flexible finish, and you will be able to apply it more quicker and easier.

For waterproofing projects requiring long-lasting and durable protection against water, both Turbo Poly Seal and Flex Seal are excellent options. Turbo Poly Seal Vs. Flex Seal ultimately depends on personal preference as well as the project’s requirements.
