10 pro tips for resin success before you ever mix the resin and hardener

tips for resin success

Believe me when I tell you that how well your resin project turns out starts long before you ever open a bottle. You can avoid problems like sticky resin, resin bubbles and wasted supplies with a little bit of planning. These 10 tips for resin success will make sure you get the results you want every time.

1. Prepare your resin crafting area.

Always go into a resin project with the idea that it is going to drip or spill everywhere. Protect your surfaces with something like wax or freezer paper or even a painter’s tarp if you are working on a large project such as pouring a resin painting. Tape off areas where you don’t want resin, like if you are pouring resin on an artboard. Make sure your surface is level and have a dome ready to cover your wet resin when you’re done to keep out dust and pet hair.

If you aren’t sure what makes a good surface to do your resin crafting on, here is a list of surfaces resin won’t stick to.

2. Gather your supplies, including resin kits, resin colors, glitter, etc. before you ever pour your resin and hardener.

Time will get away from you as it is, and you don’t want to waste any more of it looking for extras and accessories while the pot time on your resin is ticking.  This resin beginner supply checklist will help you get organized.

Pro tip: A timer is a great tool to have here. Set it to expire about when the pot time of your resin is almost up. It’s a great reminder to use or lose your mixed resin.

3. Prepare papers and other porous items for your resin projects AND make sure they are fully dry.

Just like gathering supplies, you need to make sure any papers, flowers, natural products, etc. are sealed and dry before putting them in resin. Even if they are sealed, but the sealant is wet, they will wick in moisture and stain.

If you aren’t sure how to do this, here’s how to seal papers for resin.

4. Read the directions for your resin kit. Then re-read them. Be sure you completely understand them before you start mixing. The basics you need to know are:

*How much resin and hardener to mix together. Does it mix 1:1, 2:1 or perhaps drops of hardener per ounce of resin?

*Minimum mixing amount (resin plus hardener) to get the chemical reaction to occur.

*Maximum mixing amount (resin plus hardener) so you don’t mix too much and have the resin cure all at once.

*The mixture’s pot time so you know how long you have to work with it.

*Demold time in case you want to pop the resin out of the mold before it fully cures so you can start a new project.

*Full cure time so you know when it’s fully cured and wearable or usable.

Sometimes all of this information can be a little hard to find in resin mixing instructions. If you have any questions, contact the manufacturer as they should be able to share these details with you.

5. Get your room to the ideal temperature

Resins do best in a temperature of the low 70’s F. Turn on your heat or air conditioning as necessary to get your resin crafting room to this temperature range. If you are looking for some ideas on how to warm up an area without warming up your entire house, here are some cold weather resin casting tips.

6. Warm the resin and hardener bottles

This is one of my BEST tips for resin success.  If your resin kit has been kept in a cool area, warm the bottles up in a water bath for five to ten minutes before use. Believe it or not, even in Florida, resin and hardener bottles get cool. I almost always warm my resin kit bottles before use. By warming the bottles, your resin and hardener will mix easier and with fewer bubbles.

7. Do the math on how much resin you need

This one is important if you are anything like me and hate wasting resin. We have a few articles on figuring out how much resin should you mix.

8. If you are using molds, prep them with mold release and allow to fully dry.

Prepare your molds with a mold release and allow to dry 20 to 30 minutes before use. Otherwise, the mold release may leave a cloudy film on your resin castings.

9. Have clean-up supplies handy

I like to have paper towels and a trashcan available to clean up the spills and drips that invariably happen every time I cast resin. Baby wipes also work well to clean up spilled resin on bezels, molds and even your body.

10. Have appropriate safety gear

Last but not least, while this doesn’t necessarily impact your epoxy resin casting results, it can long term if your health suffers. Please follow resin safety precautions, which includes working in a well-ventilated area and wearing appropriate protective gear such as gloves and safety glasses. The safety data sheet of the epoxy resin kit you are working with will also specify any additional safety measures you should take when using it.

  1. I have two things to add to your really awesome list:
    1) have a check list of all the supplies you need to gather before you start and double check it. And include all your prep steps too so you don’t forget to do anything.

    2)if you have long hair pull it back and secure it (head bands, ponytail holder, bandana)
    Keeping your own hair out of the resin is good. Even those with short hair might consider covering your hair with a bandana or cap.

    I have had hair get into my resin once. Learned my lesson.

    1. Hello I am just wondering if you are in Canada and do you have a postage rate the same for one item or 10 items

  2. I just want to really emphasize, WEAR THOSE GLOVES!! Get several boxes of cheap vinyl gloves so you don’t run out in the middle of a project. Don’t touch anywhere near your face, even if the resin is labeled non toxic. Take your gloves off if you need to do something like rub your eyes. It sounds obvious, but we tend not to want to stop what we’re doing. I got a terrible blister inside my eyelid once, and now I’m very very careful. Don’t grab your torch, if you use one, with sticky gloves. I did that so much with mine that I resined it shut! Gloves are an absolute necessity in my opinion.

  3. I was wonder I saw a video of red peppers done with resinLike a table. Does the peppers stay fresh and keep its shape and not get molded? Cause I thought it was cool

  4. Thanks for all your great tips.Hopefully, this will flatten out my learning curve. I want to use some tiny natural starfish in a project. Any caveats or warnings?

    1. Renzo,

  5. I’m making stepping stones with concrete and want to finish with resin over top. What’s the best reason for that project

  6. I was wondering if I am using many colors if you can mix the colors in the resin in little cups and then put the hardener in them As you need each color? Or do you need to mix it all then put your colors in ?

    1. Hi Annette, in general, you should mix the resin and hardener together first before adding the color.

  7. HI there, I have used resin several times before. This las project I had resin moving away from the edges and making areas where resin was missing. I would pour more on and spread out, continuously until it was no longer doing that. I left the projects to dry only to find that the resin did that again in some areas.
    Is it that I am just not using enough? is it the surface of my project?

  8. Hello
    I have a question, do we add the dye to the resin before or after we mix it with the hardener ? Thank you 😊

  9. Can you burn Candels in a craft you make as I would like to make Candel holders. I am brand new at this font no what kind of resign to buy or what kinds of mods actually I don’t no anything. We are starting this project for our nonprofit for are moms can help

  10. Hello! Would your project cure correctly if you added the color or glitter to part 1 of the resin BEFORE mixing it with the hardener?
