Flex Seal Liquid: Covering Areas

The number of coats and the kind of surface you are coating with flex seal liquid will both affect how much coverage you get. But I can give you a probable estimation. 1 large 16oz, covers up to 18.75 square feet, up to 37.5 square feet can be covered with 1 jumbo 32oz, up to 150 square feet with 1 giant gallon, and up to 375 square feet with 2.5 gallon max size.

What Is The Difference Between Flex Seal Spray and Flex Seal Liquid?

There are some differences between flex seal spray and flex seal liquid, although both of them are created to seal, coat, and stop leaks. The first difference between them is the ease of use. 

Flex seal spray is very easy to use rather than flex seal liquid because you can easily spray the liquid rubber directly to the surface of cracks and holes. On the other hand, you have to brush, dip, roll or pour flex seal liquid into the surface of cracks and holes.

The second difference is their applying temperature. The surface temperatures to apply flex seal spray are between 0°F and 100°F. Flex seal spray can resist temperatures between -20°F and 140°F after it has fully dried. 

On the other hand, the optimal surface temperatures for applying flex seal liquid are between 32°F and 120°F. Flex Seal Liquid can tolerate temperatures between -80°F and 350°F after it has fully dried.

Is Flex Seal spray the same as Flex Seal Liquid?

Flex Seal Spray and Flex Seal Liquid are not the same.

While both are designed to seal leaks and coat surfaces, the Spray is an aerosol ideal for quick fixes and small areas, whereas the Liquid is a brush-on or pourable product better suited for larger surfaces and requires more time and preparation to apply.

Choose based on your specific project needs.

Does Flex Seal spray really work?

Yes, Flex Seal Spray does work for its intended purposes, which is to stop leaks and seal small cracks. It’s a rubberized coating that fills in gaps and cracks to create a waterproof seal.

When applied properly, it can effectively block out water and prevent further damage.

However, the success of Flex Seal Spray depends largely on proper application and the nature of the repair. The surface should be clean, dry, and free of grease or oil.

Also, the spray is designed to seal small cracks and holes, so larger or structural damages may need a more robust solution.

It’s important to remember that while Flex Seal products can be effective for many temporary fixes or small repairs, they are not a substitute for professional repairs in more severe cases, especially when safety is a concern.

Last Opinion

Both types of flex seal are good for protecting and sealing cracks and holes. But you can choose the one that fulfills your needs. If your working surface is small and you want an easy solution, then go for flex seal spray. Otherwise, if your working surface is big and you need so much coating to do, then you can go for flex seal liquid.
