How Long Does It Take For Epoxy to Dry- A Guide on Epoxy Cure Time

New to epoxy? This may help you. With just a little bit of practice and consistency you can master the art. 

One important aspect to any epoxy resin project is understanding the curing process. 

How Long Does Epoxy Take to Dry?

The dry time will mostly depend on the exact type of epoxy resin that you’ll be using. In order to gauge the exact time, 1. Review the products mixing instructions.  2. Start with a room and product Temperature within the recommended 68-75F. These temperatures need to be consistently maintained through the entire mix, pour and cure process.

A cure can take up to 72 hours and sometimes a full week for the epoxy to completely cure. It depends.

For a typical thin coating, the project should be getting tacky within a day. This is also a good time to add another layer. This creates more of a chemical bond which is stronger than the bond created when poured onto a dried product surface.

A thicker 1” pour it may take 48/72 hours for tackiness to set in. It may require a week before the project is solid (not pliable). 

Obstructions to Fast Curing

Epoxy resin could also refuse to properly cure if a large amount of color additive is added. The color needs to be 5% less compared to the resin. The mixing also has to be precise if you’re to achieve the quality that you’re looking for.

Integral Factors that Affect Drying Time

One of the main factors will have to do with the temperature. It is recommended that you’re working with epoxy between 68-75F. Cooler temperatures will have slower cures while warmer temperatures will have faster cures.

Be careful not to start to warm with larger volumes of epoxy resin. The chemical reaction will had more heat to the mix and potentially be problematic resulting in cracking or excess cloudiness.

“Speed up the drying time by working in a room with lower temperatures”? Yet, working with warmer temperatures sounds contradictory to me. Could you please clarify? Thanks

The article says, “You can speed up the drying time by working in a room with a lower temperature.” Shouldn’t it read, …in a room with a WARMER temperature?

Last winter I had half of my resin filled molds on a heating pad I had covered with a towel last winter and set it on the lowest setting. I left the others on the table. The ones on the towel covered heating pad cured much faster than the ones that were just setting on the table.

I heard if a heating pad is incorporated in the curing process it speeds up the process, is that true?

Inquiring minds want to know. Well, really my mind.

Thanks

I want to seal my pour paintings with resin. Is this the type of resin I should use? If not, what kind would be best?

Your products are great, but maybe you could proof read your blogs before publishing. Some of it is awkward to read. (retired teacher)

Thank you for the information. I’m new to expory resin but I love it. But I’m having a few problems, I mix it like it suppose to be, but I’m having problems with holes, and floating. What am I doing wrong?
