Flex glue is a waterproof adhesive for instant bonding, and gorilla glue is a waterproof polyurethane glue for a strong bond. In this article, I will compare flex glue vs. gorilla glue so that you can select the perfect glue for your next project.

Flex Glue Vs. Gorilla Glue
Overview of Flex Glue
Flex glue is an incredibly powerful, rubberized, waterproof glue that quickly bonds, seals, and fixes almost anything. It is simple to apply. The extremely thick adhesive from flex glue sticks to the surface and may be used on wet or dry surfaces. You can even use it underwater.
It is easily paintable, solvent free, and UV resistant. It has a low odor, and it will not shrink or crack easily. It works perfectly on surfaces like- glass, wood, metal, plastics, etc. For optimal flow, it should cut close to the nozzle’s base.

How To Use Flex Glue?
It might result in an allergic skin response. Limit contact with the skin and eyes. Use safety glasses and gloves.
a) Prepare the surface area before using it, regardless of the intended usage. Make sure there is no dirt, oil, or grease on the surface.
b) After cleaning and preparing the area, detach the nozzle and trim the hole to the appropriate length. For the immediate grab to take hold, apply generously to the side of the surface being bonded and push down hard for at least 10 to 30 seconds. Reposition the item, if necessary, within 10 minutes of application.
c) Give the cure between 24 and 48 hours. It will grow to its strongest point in 7 days.
d) Allow enough flex glue to clot at the end after usage so that it forms a stopper, then tighten the screw cap. Plug it back in and utilize it once more for your next project.
Overview of Gorilla Glue
Gorilla glue creates a super strong bond among metal, wood, glass, etc. Its bond is super strong and one hundred percent waterproof. Its bond will not break even if it is exposed to the outdoor environment. The bond will be held as it is in tough environments like- hot and cold temperatures.
Gorilla glue is well known for its indoor and outdoor applications. It is also well known for its industrial holding power and versatility. Usually, porous materials or wood are joined together with gorilla glue.
How To Use Gorilla Glue?
Gorilla Glue will ruin clothing and stain skin, so be careful. Every surface needs to be spotless and tightly fitted. To avoid skin contact, put on gloves.
a) Water cures Gorilla Glue. Water one surface just a little bit. Prior to bonding, lightly dampen both surfaces and scratch non-porous surfaces (such as glass and metal) and thick hardwoods. Don’t fill the bottle with water.
b) Apply a little coating of glue to the opposite surface. Avoid using too much adhesive. Three to four times as much Gorilla Glue will foam.
c) Hold items in place for a couple of hours. To apply clamping pressure, hefty items might be used. Better clamping increases bond line strength. Whole recovery in 24 hours.

Which One Is Best? Flex Glue or Gorilla Glue?
Flex glue appears to be a soft rubber compound for anything and cures waterproof at room temperature. On the other hand, Gorilla Glue is a wood glue that seeps into the wood and solidifies once it has dried.
Both of them are waterproof and create a solid, strong bond to hold things together. But flex glue is not as good as gorilla flue for wood. On the other hand, gorilla glue may not work as good as flex glue for wet applications.
Despite my positive experiences with both, I wouldn’t use flex glue on wood or gorilla glue in moist environments like aquariums.

Is Gorilla Glue Waterproof?
As they claim, gorilla glue is one hundred percent waterproof. So, you can use it to stop water from leaking on underwater surfaces.
How Strong Is Flex Glue?
In TV advertisements, flex glue is demonstrated holding objects weighing more than 1000 pounds and functioning underwater.
Does Flex Glue Work on Plastic?
On its website, flex glue claims that it will work on some plastics as well.
Both flex glue and gorilla glue create a strong bond between different materials. But definitely, gorilla glue is the best for wood applications, and flex is the best for wet applications.
