All of these products are guaranteed to create a watertight seal keeping out the elements. 

A leaky pipe? Flex Seal Tape can fix it! A crack in your foundation? Flex Seal Spray or Liquid can fix it! You'll be hard pressed to find a repair that can't be fixed with a Flex Seal product. 


What is Flex Seal made of? 

Flex Seal is a thick and durable, rubberized coating specially formulated to start as a liquid, seep into cracks and holes, and dry as a flexible rubber that's watertight! 

How long does it take Flex Seal to dry? 

Flex Seal dry time will vary depending on temperature, humidity, and thickness of the coating. Generally, Flex Seal will dry to the touch in two hours and be fully cured by 24 hours. 

Can Flex Seal be painted over?

Once fully cured, Flex Seal products can be painted to match any existing color. Flex Seal even has a variety of it's own color options with Flex Seal Sprays!

Flex Seal Spray

 A couple of safety tips to know before using Flex Seal Spray:

  • Make sure workspace is well-ventilated
  • Don’t smoke around Flex Seal
  • Don’t use around heat, sparks, or open flames 

To start your Flex Seal Spray repair, shake the can vigorously for about a minute. The can has a variable pressure nozzle, which means you can put on a light coat or a thicker coat depending on the job at hand. For the biggest leaks or cracks, you may even need multiple coats. Always make sure to let each coat dry completely before adding a new coat of Flex Seal Spray.


Once you've sprayed your problem area, simply wait for the solution to dry. If it's tacky or soft, Flex Seal Spray isn’t dry. Waiting until it is completely dry ensures the best adhesion possible. Another way to check is to hold it up to a light. If light passes through, then your project isn’t sealed. You’ll need to add another coat.

Once done, clear the Flex Seal Spray nozzle by turning it upside down over a trash can. Give a few quick sprays. The next time you go to use Flex Seal Spray, it won’t be clogged!


Flex Seal Spray comes in a variety of colors including:

  • White
  • Black
  • Clear
  • Red
  • Blue
  • Almond
  • Brown
  • Green
  • Silver
  • Terra Cotta
  • Brite White
