Five most common resin errors

When the resin is fun you can also perform resin errors in your work.If the resin is fun to make it can also turn into a beast ruining your work, though it is your mistake. There are few common resin errors you will perform. And some possible solutions are also available when action is complete.

1.   Dark areas on embedded sections.

This is when you embed papers or porous sections into your resin castings only to discover later that the item has stains or dark areas on it like it is moist.  This occurs when the resin moistens into the paper.

Possible solution for Resin Errors

Cover any paper or porous items ahead of time with a clear-drying white glue i.e Ultra seal glue or an aerosol sealant. For example, gloss resin sealer spray

These methods are helpful for how papers and other items are sealed for casting in resin.

2.  Resin castings are gloomy or full of bubbles.

This can occur when the resin reacted with the embedded elements.  The resin can react with your embedments, acid especially if you are discussing vintage papers.

There are a lot of intentions why bubbles can occur in resin.  Here are 10 tips to avoid bubbles in the resin.

Possible Solutions for Resin Errors

Cover embedments in sealant before using it

Ensure that the resin is warm before mixing.  Put both bottles in a warm water bath for 5 to 10 minutes before emitting.  Be sure your containers are dry before functioning the resin to avoid any water contamination.

Are you using a new colorant?  The resin may be reacting with that section.  Once again, make sure all supplements are dry.

3.  Resin is not fully cured after the recommended curing time.

This can be anything from yet, a bit sticky on top to a huge goopy mess.

Possible Solutions for Resin Errors

Listen to label directions strictly.  Do not add more or less hardener and measure it clearly and that must be accurate. While it is meaningful in a lot of other blogs and youtube videos, I never recommend using the caps to the resin containers as measuring tools.  You cannot get a factual measurement this way.  Try the adequate size mixing cups to compute and mix your resin.

  • Make sure your mixing utensils and bottles are dry.  Store your resin in a climate-controlled atmosphere.  Having resin in an area where there are big temperature changes. (For example garage or storage unit) can allow moisture to form on the inside of your resin container cap.  This steam then sweats into your resin.
  • Make sure you use the minimum amount of resin required for the chemical reaction of curing to survive.  For instance, if you’re using a 1:1 resin to harden the resin kit, you cannot mix two drops of resin with two drops of hardener and want it to cure.  Resin curing is a chemical reaction that needs a minimum amount of each ingredient for it to occur.  
  • If your pieces end up being just a bit unstylish on top, you can begin sanding them down and recoat them with resin.  If your resin is a semi-hardened mess, there is not any aspect to keep this resin.  You can use it to scoop it out of the mold and clean it by wearing gloves when performing this to remove the leftover resin, but it may be manageable for you to throw away the mold and start over.

4.  Resin sticks to my mold.

Determining your resin is cured, you can use these resin troubleshooting tricks.

Possible Solutions for Resin Errors

First and foremost, we always suggest using a mold release — even with silicone molds.  It’s a nice way to get into and prolongs the energy of your mold.

If the cured resin is stuck to your reusable plastic mold, you can use placing the mold in the freezer for a moment.  Take the mold and see if you can remove the resin from the mold.  (You can use smacking the mold on a hard countertop.)  If the resin doesn’t come out, you can use leaving the mold in the freezer for another few minutes.  And you should know resin does not come out of the mold after 10 minutes.

If the resin is stuck to your mold, and you are afraid there’s no manner to get that out.  However, that takes me to another important point that urethane and silicone don’t manipulate together.    The times I have learned about resin sticking to a silicone mold have always implicated silicone and polyurethane where a mold release was not borrowed.  If you’re working with silicone into silicone, you will require to have a mold release, oppositely, you will make one big block of silicone.

5.  Resin gets hot and cures within minutes.

There is always a slight heat when the resin is mixed due to the exothermic quality of the reaction and curing.  Excess heat, nevertheless, will influence the resin to cure quickly.

Possible Solutions for Resin Errors

Use the proper mixing utensils and bottles.  While we realize it is attractive to use old plastic bottles, party cups, and styrofoam bottles to mix resin, these items have chemicals on the surface that can stimulate the reaction that happens between the resin and hardener.  

  1. Do not add more hardeners than is suggested.  This will speed up the reaction and can result in the resin curing very quickly.
  2. Do not mix the suggested mixing quantity of hardener and resin at once.


Resin is an amazing art. However, you can spoil this fun by attempting resin errors. And one this I will say 4 things you must remember while making a mixture. Wear gloves, Do not mix water, avoid moisture from your art. The temperature must be 25° to 30°.
