Resin tumbler DIY – how to add resin to a tumbler

How to decorate a tumbler with resin

by Angie Holden

I have seen several resin tumbler DIY ideas lately and wanted to put my spin on the trend with some resin marbling. This project is easy and perfect for those who want to customize their drinkware. Use any insulated tumbler that you love and personalize the project with your favorite color combination.

Resin supplies needed:

● Insulated tumbler
● Tumbler turner (I am using the Spin It from We R Memory Keepers.)
Resin Obsession Crystal Doming Resin

Mixing cups
Stir sticks
Gloves and other protective equipment
● Painter’s tape
● Cardboard or other protective paper
● Craft paint
● Paintbrush

 

Step 1:  Prime with white paint

Start by painting your tumbler if needed. Some tumblers come powder coated already. The one I am using was plain steel, so I gave it a few coats of white paint before starting. I primed it with white paint in case any of the tumbler peeks through the resin. Pro tip:  You can use the tumbler turner for the painting as well as the pouring.

Allow the paint to dry in between coats as well as when you are completely done, before adding any resin.

Step 2:  Cover your crafting area

When ready to pour your resin, be sure to cover your area completely because resin is going to drip off the tumbler. I am using scrap cardboard that I can throw away once the resin cures.

Step 3:  Cover cup with tape

Cover the bottom of the cup with painter’s tape.  This will catch any resin drips.  You will peel this off later.

Add painter’s tape to the inside of the cup to catch any resin that may spill or drip over into the inside. NOTE: My tumbler has a lid and straw so that is what will be used for drinking. If you are going to drink directly from the tumbler, ensure your resin is food safe or leave a lip that is not coated at the top.

Step 4:  Mix the resin

Now it’s time to get to the fun part of your resin tumbler DIY!  Measure equal parts of the resin components in a large mixing cup and stir well. Then, divide this up into as many smaller containers as you have colors. Please always remember to wear safety equipment when working with resin.

Step 5:  Color the resin

Add drops of pigment to each of your smaller cups. You can mix and match the colors to create shades of the original.

Mix each of these well.

Step 6:  Start the rotating motor and add the resin

Turn the tumbler turner on low and allow your cup to spin. Straighten the cup if necessary so that it spins correctly. Drip your resin onto your cup surface.

You will want to drip each color randomly as the cup spins, getting each color all over the cup.

My resin tumbler DIY looked like this once I had all of my colored resin applied. It will start to run together and blend at this point.

I did, however, need additional resin to get full coverage. Just measure and mix some additional clear resin and pour however much you need onto your cup.

blending colors

Use a stir stick to start pushing the resin around on the cup surface. Just barely touch the tip to the surface so that the components spread and do not mix too much.

Continue with this method all the way down the cup until you are happy with the coverage. Remember you can always add more resin if you need it but it is hard to remove it once it is added.

Step 7:  Let cup spin while the resin cures

Once you are happy with your marbling, pop any bubbles while your cup continues to spin. Then, leave the cup spinning for about 4 hours while the resin hardens. I like to leave a little bit of resin in a cup beside my project so I can check on the cure before turning off my turner.

When the resin is thick enough that it doesn’t run, you can turn off your turner but leave the cup in place for the entire cure time. I left mine for about 18 hours, then took off the turner.

Step 8:  Finish

This resin tumbler DIY is almost done!  Remove the tape from both ends and give a wash with dish soap before using it.  Tumblers coated with resin shouldn’t go in your dishwasher, but they can take a good handwashing any day.

  1. Looks great.. but wouldn’t you have to allow for the lid to go on? The resin would make it harder.. the room smaller where there lid clips over?

  2. Can I resign right on the stainless steel or do I have to paint it? I want to put a decal on the stainless steel and leave the “natural” stainless stainless silver color? Do I need to sand the stainless steel 1st if I don’t paint it? Thanks.

  3. If you wanted a decal after this marbling process, could you sand, put the decal on and then another coat of resin (clear, of course)?

  4. When I apply the resin it doesn’t come out really smooth. It’s like it is repelled in some places & over thick (kinda wavy) in others. I also can’t get rid of all the bubbles even with a heat gun or torch. What am I doing wrong?
    Thanks

  5. How can I prevent things from sticking to the resin during the curing process? I don’t know what else to do… I cover them with boxes and they still manage to catch dust particles in the air. I currently have a cured bottles and it caught dust particles…is there anyway I can fix this?

    1. Hi Sofia, I’m sorry this is happening to you. It sounds like you need to check on your pieces towards the end of the pot time to check for stray hairs and dust. I also find it helps me to work in a room that no one else visits, especially anything furry!
