PROS and CONS of Flex glue

Flex glue is one of the strongest adhesives that can be used on almost every type of surface and even wet surfaces. Its versatile use and features make it better than many other options. Flex glue dries fast and its bond strength is increased over time which is called curing. If one uses it and leaves it the way it is for some days, the bond it will create will be better than the gorilla glue bond. That’s how flex glue works. It is so good that some of its features sometimes make us struggle.

Let’s see what we can unfold about flex glue, its uses, pros, and cons.

What is Flex Glue?

Flex glue is a rubberized adhesive that works on any surface and even underwater or on wet surfaces. Is flex Glue waterproof? Of course, it is. That’s why it is versatile. The bond it makes is powerful. When it is cured for a certain amount of time, its bond strength can surpass even the gorilla glue. We know each type of glue has its own characteristics and ways to work. Flex glue can bond immediately upon use and its strength just increases over time. The curing time varies depending on the material you used it on and its size as well. The highest curing took a week or more and the result was worth waiting for.

What is Flex Glue used for?

As we said, Flex glue can be used on almost any surface including underwater. You can use this glue on many types of surfaces. However, that does not mean it works on all surfaces. Always use it on a sample of the same thing that you are going to use it on to check if it really works or not. You can use it on-

  • Wood
  • Metal
  • Brick / Concrete
  • Plastic
  • Foam
  • PVC 
  • Stone
  • Tiles/ Ceramic
  • Glass, Fiberglass
  • Plaster, walls
  • Rubber
  • Clay, masonry
  • EPS

And more.

How to use Flex Glue?

Using Flex glue is really easy. The company itself said it is easy to use.

  1. First, screw the nozzle off from the glue.
  2. Then cut the tip off leaving a little behind.
  3. Put the nozzle back on
  4. Cut a small part of the nozzle
  5. Either use a gun to push the glue or you can use your hand to use it on any surface.

Since flex glue comes in different types of packaging, you can use it the way you want. However, make sure to seal it well before storing it. If you store it well, it can still be usable after 2 years. Inappropriate storing for a long time will leave it to create a layer that will thicken and harden over time.

Is Flex Glue Waterproof?

Flex glue is waterproof. You can easily use it on wet surfaces or even underwater and it will work just as it should. There are not many waterproof types of glue. That’s why being one of the ones makes it even more unique.

Flex glue works on almost every type of surface and it is no surprise it can be used on wet surfaces as well. Water cannot dissolve or break down its components thus the bond cannot be broken.

PROS of Flex Glue

Can be used on pretty much all types of surface

Seals fast upon used

After curing food sometimes, its strength increases

Can be used underwater

Can withstand extremely high or low temperature

The bond is powerful

Versatile and strong Usage

CONS of Flex Glue

Sometimes hardens even before trying to put pieces together

Does the bare minimum compared to its advertisement

Pricier than its peer glues

Frequently asked question

  1. How much time is needed for flex glue to dry?

    Flex glue will dry immediately after 24 hours. It will be firm and won't stick to your hand if you touch it. However, this much time is not enough for increasing the durability. Flex glue works better after curing. Curing means leaving it alone for a few days and it will form a stronger bond than before. The more time it gets, the better the bond is created.

  2. Where is flex glue used?

    The best part of flex glue is that you can use it on almost every surface especially tough surfaces like metal, stone, marble, PVC, bricks, tiles, ceramic, etc. Also, it can be used on thin surfaces as well such as fiberglass, sheetrock, glass, etc.

  3. How to remove flex glue?

    Since curing makes flex glue bond stronger, you can use a scraper or chisel to scrape the glue off the surface. Other than that, there is hardly any solution that can remove flex glue. However, if it is still in the primary stage and in the drying stage, use an Isopropyl alcohol solution (C3H8O). And if it is not fully dried yet, use a dry cloth to remove it.

  4. Can I use flex glue on a wet surface?

    You can use flex glue on a wet surface because it is waterproof. Be it a wet or damp surface, you can use flex glue on it and it will create a strong bond as it does easily. Flex glue bonds stronger on dry surfaces so you have to make sure to wipe well before putting it.
