Why Is My Resin Sticky?

Doing art projects with resin can be very fun.  Resin makes your paintings, artwork or even your own photograph look like it has life.  It’s glass-like finish will take your artwork to the next level. However, dealing with resin can also be very tricky.  You need to be patient because it will take some time before you master it. 

Artist Resin is an epoxy resin that is user-friendly.  But, applying and mixing Artist Resin should be done the right way from the beginning to the end.  Why? Because resin can be sticky when the steps are not followed properly. 

If you can find sticky and soft areas on your resin application, it means that your resin did not cure properly.  Sticky resin is a big “no” it will stay tacky even after a few days, and could destroy your artwork.

To avoid sticky resin, here’s what you can do:

First, epoxy resin comes in 2 parts: Part A and Part B.  When mixing the two, make sure you are following the directions carefully.

When mixing the resin and the hardener, be sure and measure correctly and mix it thoroughly.   If your 1:1 ratio is off, the resin might not cure properly. If the resin is not cured correctly, it can turn into a sticky mess.

 There are instances that epoxy resin does not cure properly.  Here are some of the reasons why:

Wrong Measurements

Some people think that if they put in more hardener the resin will harden faster, but that’s wrong.  Follow the proper 1:1 ratio. If the parts are not equal, the resin will not cure properly and will end up tacky.

Under Mixing

Once you’ve made sure your mixing ratio is 1:1, it’s important to mix the ingredients thoroughly.  Do not mix too fast. Mix for three to four minutes and make sure to scrape the sides and the bottom of your mixing cup to ensure every bit of the resin will cure.

 Using Wet Utensils

 One thing you need to know about resin is that it does not like water. They are not compatible. The tiniest drop of water can cause problems in your resin, such as bubbles, cloudiness, and an improper cure. Your utensils— measuring cups, stirring spatulas and spreaders— should be dry and clean for best resin results.

Temperature

This is a big factor to consider when curing the resin. Keep in mind that warm temperatures make curing times a bit faster and colder temperatures will make curing times a bit slower.  For Artist Resin, the ideal room temperature is between 71-75 degrees. If the temperature is colder than that, the resin will thicken and be harder to mix, and bubbles will possibly appear. It will also take longer to cure.

Mixing Brands

Make sure Part A and Part B are the same brand.  Mixing resin brands should be avoided. Keep in mind that every paired resin and hardener works together as a system and should not be interchanged.
