Can Epoxy Resin Get Wet?

Epoxy resin has some pretty cool properties. It is a two-component liquid plastic that hardens into a strong and durable material. 

It can be used in many different projects, including surfboards, boats, or even for your next water fountain! But what happens when epoxy resin gets wet?

What Happens If Resin Gets Wet?

Epoxy resin has a lot of great properties and can be used in many different projects. 

One thing to keep in mind is that epoxy cannot get wet! If your project requires you to work with water then try using polyester, but if not, stick with epoxy for your next big project.

If the resin gets wet you will have some issues because it starts to soften at about 35 degrees Celsius (or 95 Fahrenheit). 

It also doesn’t do well when mixed together with chemicals like acids- which means don’t use bleach on any tightly sealed surfaces where the two might come into contact or mix!

Is Epoxy Resin Waterproof?

Epoxy resin has some pretty cool properties- but it is not waterproof.

 It can still get wet, and if the temperature or chemical conditions are right (like acid) then that water will start to dissolve your epoxy!

Can Be Cured Resin Get Wet?

Epoxy resin can get wet, but it cannot be cured. This means that once your project is finished and you need to maintain the epoxy for another period of time- do not let it stay in contact with any liquids!

Will Epoxy Set If It Gets Wet?

Epoxy will not set if it gets wet. The chemical reaction that occurs in epoxy is irreversible, the main part of this process called “polymerization” can’t be stopped once it starts!

Does Tacky Epoxy Ever Cure?

Epoxy resin will never cure. If you need to maintain your project for a long period of time, make sure none of the epoxies is in contact with any liquids!

Why Is My Resin Rubbery?

If your resin feels rubbery and is not hardening then it has most likely been exposed to moisture. 

If the epoxy starts to change its texture, you may want to discard that batch, otherwise, it will never cure!

How Long Will Epoxy Last?

If you are using epoxy for a project that is not exposed to water then the lifespan of your epoxy will vary. 

If it does come into contact with moisture, however, it can start to soften and lose consistency in about 30-35 degrees Celsius (or 95 Fahrenheit).

Epoxies last anywhere from 20-30 years if they stay dry! The average life span is somewhere between 25-40 years.

Does Epoxy Yellow Over Time?

Epoxy will yellow over time if it is exposed to excessive amounts of UV radiation. 

If you are using epoxy resin for a project that has any exposure- make sure to use epoxies with ultraviolet inhibitors! 

Otherwise, just try and keep your epoxy out of the sun, or at least from direct contact with sunlight as much as possible.

If not, then there is no way for preventing this process which also means Epoxies should be stored in dark environments whenever possible and re-coloring might need to take place every few years depending on the severity of the damage done by UV rays.

Why Is My Uv Resin Still Tacky?

If you are using an epoxy resin with UV inhibitors, and it is still tacky- then that means the inhibitor has not been set. 

When mixing your two components together make sure to leave them be for at least a few hours before working on any project!

Does Epoxy Shrink As A Cure?

Epoxy will shrink as a cure! You may need to account for this when making something with epoxies.

 Usually, the total amount of shrinking is about 0-15%, but you should measure that first before starting your project so it doesn’t end up being too big or small because the epoxy shrunk more than expected.

The best way to avoid any issues and make sure everything goes smoothly is by measuring twice and cutting once (or using an extra coat!)

Can Epoxy Floors Get Wet?

Epoxy floors can get wet, but they shouldn’t be in contact with water. Epoxies are not waterproof and if your epoxy floor is exposed to a lot of moisture then it will start to soften up this could cause some problems and issues.


Epoxy resin is not waterproof and should be stored in a dark environment to protect it from UV radiation.

 It can still get wet, but if the temperature or chemical conditions are right (like acid) then that water will start to dissolve your epoxy!
