How It Works

Flex Seal comes out of its spray bottle as a thick liquid that will seep into holes and cracks, but turns into a watertight, yet flexible rubber coating as it dries. Once it has become rubberized, it will prevent water from getting into cracks and damaging an object, and it'll also protect an object's surface from corrosion. Another function it has is the ability to stop vibrations and deaden noise, so if you're tired of rain pounding against your outdoor furniture or decorations, you'll benefit from spraying those things with this solution.


  • Twelve Shades Available

    Besides the original clear, black, and Brite, you'll also be able to get Flex Seal in nine new colors, including white, brown, almond, blue, silver, green, red, terra cotta, and yellow. Therefore, if you like your home and yard to look bright, eye-catching and interesting, you'll have no problem with that.

  • Efficient

    With just one spray, this solution will coat and seal the majority of objects quickly and entirely.

  • Portable

    Each can of this spray is 14 ounces in size, so you'll be able to carry yours around your home and yard, or even in your vehicle, without difficulty.

  • Flexible

    Once dry, this solution remains flexible, so if you need to bend an object that you've treated with it, you'll still be able to do so.

  • Long Lasting

    If you coat an object with Flex Seal, that coating will last for at least a few years. Even if it's subjected to hot temperatures in the summer, it won't drip or sag, nor will it peel or crack if exposed to very cold temperatures in the winter.

  • Works on Wet and Dry Surfaces

    You can apply this solution to both wet and dry surfaces, as it'll work effectively on either. That means if something has recently been painted or is wet due to rainy weather, you won't need to wait to give it a protective sealing or coating.

  • Two Bottles Per Set

    You'll get two bottles of this spray per set, in the color of your choice.

Positive Points

  • Useful for Arts and Crafts

    In addition to using it to protect household objects and perform repairs, you'll be able to use Flex Seal to help you with art and crafting projects. It'll come in handy as a glue alternative, or when you want to add some color to something plain. Plus, you may want to spray certain projects with the clear version of the solution in order to preserve their original quality.

  • Comes With Flex Shot

    With each set of two Flex Seal cans, you'll also get a smaller can of Flex Shot, a similar solution that is used for caulking.

Negative Points

  • One Color Per Set

    Even though you'll get two bottles of Flex Seal per set, they both must be the same color. It would be helpful if there was the option of selecting a second color for the second can.


  • Spray Paint

    You can use spray paint to add bright color to various objects in and around your home, but it is thinner than Flex Seal, so it won't cover your objects as quickly or effectively. You'll probably need to use more than one coat to get the same result as you would with one spray of Flex Seal. Moreover, your spray paint may not stay put unless you use a primer and a sealer.
