Flex Paste is a substance that's been designed to seal cracks and holes in virtually any surface by transforming into a flexible, expandable form of rubber as it dries. Aside from sealing cracks and holes and completing other home repairs, it's stated that you might find this substance suitable for crafting projects, as a variation of modeling clay. The formula comes in containers of five different sizes, and regardless of the size you select, you'll have a choice between the shades of white and black.

How to Use (Step by Step)

  1. Prepare Surface

    Before you start using your Flex Paste, you'll need to prepare the surface that you want to treat with it. This might be a glass container with a crack in it, a wooden object with a hole in it, or even a wall with a small gap. For the best results possible, the surface must have no grease, oil, or dirt on it. At this point, it's also best if you put on clothing that'll protect your skin, along with a form of protective eyewear (such as a pair of goggles).

  2. Open Container and Scoop

    Next, open up your container's lid and remove the protective foil from the top, along with the included silica gel packet. Don't discard either of these things, as you'll need them later. Grab a putty knife, a spatula, a trowel or some similar tool, and scoop a portion of paste from the container without digging down deep.

  3. Apply Paste to Surface

    Once you've got some paste on your spatula (or whichever tool you've chosen to use), begin applying it gently and smoothly to the surface you need to treat. Only apply it around the hole, gap or crack, and not to the rest of the object or area you're treating, or else you'll end up wasting some. You may only need one coat, but if you think you'll need more than one, wait 15 to 30 minutes before dipping your applicator into the container again to get another portion.

  4. Let Paste Cure

    After you've applied enough coats of Flex Paste to your chosen object or area, let it cure in place for 24 to 48 hours, as this will enable it to turn into durable rubber. If it still appears soft or wet after this time period is over, you may need to cure it for longer. Keep in mind that you'll be able to paint it after the curing is done, but sanding this substance isn't recommended. As it's curing, it almost goes without saying that you should avoid touching it.

Cleaning Your Work Area

  1. Use Acetone or Mineral Spirits

    When you're done completing your jobs of the day with Flex Paste, you'll have to follow a specific clean-up process. The first thing you'll need to do is clean your work area with acetone or mineral spirits, making sure that you don't get either of these substances on the object that's currently curing. If any of the paste is on your skin, you can use acetone to remove it, but you must not use water to clean the paste off of anything.

  2. Close up Paste Container

    Once you and your work area are fairly clean, replace the foil on your paste container, making sure that you press it against the edges extremely tightly. Otherwise, the paste could dry up and become less useful. Replace the silica gel packet you removed at the beginning of your first job, too, and finally, put the plastic lid back on.

  3. Store Container Away

    Last but not least, finish your clean-up by storing your container in a cool, dry area. Humidity can interfere with its shelf life, and it cannot withstand temperatures of more than 150 degrees Fahrenheit before it has cured.

Features

  • Black or White

    Flex Paste comes in both black and white, so you might want to get a container in both shades or choose the shade that will best suit most of the repairs you want to complete. If quite a few of them might take place inside a white bathroom or kitchen, white may be your best bet, while black could be more suitable for outdoor repairs—but it's all up to you.

  • Five Sizes Available

    You'll also be able to choose your container size, basing that decision on your own needs. The smallest size of Flex Paste is the nine-ounce cartridge, which you'll have to put into a caulking gun, but you can get tubs ranging in weight from one to 12 pounds. If you choose any of these tubs, you won't require a caulking gun.

  • For Indoor or Outdoor Use

    Flex Paste can be used either indoors or outdoors, on almost any surface, such as wood, metal, tile, glass or concrete. The seal that it creates will be watertight, so you can use it in something that's going to be filled with water, as long as humans or other living things won't be drinking that water. It's also resistant to damage that might come from UV rays, mildew, and certain types of weather, such as rain and snow.

  • No Odor After Curing

    It's specified that this paste will give off a bit of an odor as someone is applying it, but that this odor will disappear after the paste has cured. Therefore, you won't have to put up with a funky smell as you use anything that you've repaired with it.

Positive Points

  • Can Use for Crafting Projects

    In addition to repairs around the house and yard, if you're a crafter of any sort, you may find Flex Paste useful within your projects. Similar to modeling clay, it can be spread and shaped into various objects, and you'll be able to paint it a different color after it's done curing. If you're comfortable with doing this, you can even add designs to its texture with a putty knife or a similar tool right after you've applied it, and it'll retain those designs as it cures.

Negative Points

  • Must Provide Own Tools

    It would be helpful if a spatula, trowel or putty knife could be included with each container of this paste, but you'll actually have to provide your own. You'll also have to provide any type of protective equipment that you'll make use of throughout the application process, such as gloves or goggles.

Warnings

  • Not for Flammable Containers

    Flex Paste can be used to repair a wide variety of things, but it should never be used to repair a gas tank or any other containers that could be flammable. While it's being stored, it should also be kept away from flammable liquids. Another thing to avoid using this paste on is any electrical wire, as the safety of using it with these hasn't been tested.

Will Flex Paste work on an iron roof in Hawaii? I have a section that overlays another section. Due to a poor pitch, during heavy rains, rain reverses back up under overlay sections! Will this product be able to handle the heat of the iron roof and what would life expectancy be?

No, Flex Paste only works in the continental United States. It won’t work in Alaska or Hawaii.
