Finally a video I've been looking for. Perfectly explained and now I know how to fix my cup perfect for customers. 🤩👍🏻
Thank you so much for this video! I am working on my first tumbler and have a ton of bumps, especially around the Chunky glitter!! I have been looking on UA-cam all day with no video on this, then yours finally popped up!! Now I feel a little better about sanding it!!
That tumbler reminds me of the tootsie roll commercials from when I was young! I love those commercials! Beautiful cup, thank you for sharing.
Thank you , finally someone talks about the problems, every video is about how beautiful they work is but nobody mentions anything about the issues 😞
So appreciate this Video thank you ❤
I'm so happy you've made this video. I'm new to tumblers and I've been trying to figure out how to get rid of the lumps and bumps.
Thank you! Your video and vocal delivery is very clear. I now know exactly what I need to do.
Thank you thank you!! 🎉 First video out of hundreds that has really addressed the issue.
i am just starting out and had not seen this video yet. I have a tumbler with lumpy gllitter and a few bumps on the smooth areas. Sanding them is exactly what I did. The other problem was a small space that did not get covered with glitter. I sanded around it, applied modpodge, and added the glitter. It is drying now and when it is dried I'll put on the next coat of expoy. After all that I found your video and felt a whole lot better about the sanding, not sure yet about the glitter. Thank you so much!!
Thank you for this video. It was incredibly helpful and gave me a bit more confidence in trying to learn this craft.
This video was VERY helpful and answered every question I was looking for the answer to. Thank you 🙌
I'm so glad I've found this video, I've been looking as well. It's so frustrating to put the final coats and you have bumps and lumps
I’m just starting to make cups and I have to say I felt frustrated a few minutes ago because I made a glitter tumbler and after my second coat of Epoxy I felt the bumps. I didn’t know what I was doing wrong, but this video gave me some great advice that I will take into practice tomorrow, and hoping I can fix my cup. 😊 Thank you so much!💜
Dani Salda so glad it helped!
This video was so helpful, I just subscribed. Thank you for the valuable information.
Great video, answers a lot of my newbie questions💖
So glad I found your video. I had made a cup last night and after letting it cure I noticed the glitter was poking out. I did sand it down and going to apply another layer of epoxy hoping itll work
Thank you so much for these tips and tricks! Very helpful!
Thank You! Glad you find it helpful!
thank you I had a few smudges and was freaking out! appreciate your help
Thank you so much! This helped me so much, Also I love your nails❤
THANK YOU!! Thank you SO much for this video! You are amazing & helped so much!
I'm so glad I found your video, it was exactly what I was trying to find!
Thank you so much for your great information! 💗
Thank you so much for the video. I've been doing tumblers for a while now and this is the first time I couldn't figure 5he problem out. I want to make it stop happening.
This was sooooooo helpful- thank you so much
Thank you for this, i was having a hard time with epoxy!!!
Thank you for this!! Very helpful!!
Thank you this is an amazing! This video brought me peace and educated me. I guess I’m not alone, lol I have hope lol 😊
Thanx!!! I had been feeling super disappointed with how my cups have been coming out
Thank you. Thank you. Thank you. 😁 Your video was very helpful. I got some buldging epoxy at the bottom of a couple cups and want sure why that happened or how to fix it.
this was so helpful. thank u
I love the marbling you have on that cup! Beautiful! 😍
Thank you for this tutorial!
Thank you so much for this video. I was about to give up making tumblers because the bumps from epoxy were getting worse with every cup. I did what you showed us in this video and it looks great now. I try to avoid putting epoxy on more than once and do a thin coat. That’s not going to work especially with glitter.
So glad you found it helpful!
very helpful, thank you!
YES!!! THANK YOU!!!!
Thank you so much for this ❣️❣️❣️
Thank you for this!!!
Very cool & interesting. 👍👍
Thanks Meg!
Thank you so much.
Thank you for this video. You are the only person who said you need to use a finish on the cup before you apply expoxy. But I am still having a problem. I took a stainless steel cup and lightly sanded it and then washed it off and dried it. Did not touch the cup again without having a new pair of gloves on. then I put a spray coat of Rustoleum enamel paint on the cup, then let it dry, Wiped it again and put it on my cup turner using my gloves, then did an acrylic paint pour over the cup. I let it sit until all the paint was dry, then sprayed a coat of Rustoleum clear over it and let that dry. Mixed my expoxy for 4-5 mins. using a timer. Once the cup was dry I applied the expoxy with my hand and it was so pretty and smooth. I also torched it. But within 5 mins. or so the fisheyes start popping up. I am so tired of this and I don't know why it keeps happening. Can you help me?
Send me an email.
I would love to hear a response to this!! Please! I’m new and also trying to fix fish eyes!
Very useful thank you
Thank you for this video. I just did my first cup for my daughter and I think I messed it up by just applying more epoxy. It looks like a bumpy road.
Where do you pick up your sandpaper? And what grit do you use?
I just finished a cup and it's almost perfect. Three is one tiny pointer bump. Very small but you can feel it. Is there anything I can do other than sanding and putting another coat of epoxy?
I have a tumbler that is beautiful except the epoxy didn't stick everywhere and there are places where you can see the "raw" cup where it didn't take. I prepped my cup by using alcohol and made sure that the epoxy was totally covering the cup. While it was turning, I saw this was happening and tried to add more epoxy to the "holes" and it just didn't work. I would appreciate any help with how to avoid this again and would love to see a video on this. Thank you for your time and for sharing your knowledge.
I'm in the same boat right now can't find an answer
Thank you
Thank you again
Than u so much xx
Thank you!
Loved your video. I started my very first alcohol ink wood grain tumbler. Of course I had bubbles AND waves. I sanded it and Unfortunately sanded down to the tumbler logo (BUILT). Any suggestions/advice would be GREATLY APPRECIATED.
Fatima Huerta - if it happens where you see you have a thin area of epoxy...put another coat on... and then sand that layer... I have sanded color off before and just applied more paint to mask on the epoxy layer - but it would be more difficult with wood grain technique
Would have liked to see you use your heat gun in this as well..... But thank you!!! This definitely helped!
I did epoxy own a skinny tumbler which I believe is plastic and for some reason I got what looks like little spider web cracks all through it but I cant find a video on why this occurred or how to fix it, do you have any suggestions for that?
I'm happy you make these videos.
I'm having an issue with the epoxy seems to wave along the cup. Table is leveled. Any suggestions?
Put a level on the end of your cup and check it
I’m having issues with cups that have a curve in them.. The top and bottom of resin on the cup goes towards the middle.
Thank u so much for this video! I'm brand new to all this! And I'm so disappointed, I had a beautiful cup and the epoxy was uneven towards the bottom. For some reason my cups (I use the 30oz from Walmart) do not want to stay on the ball and stay level. They start out level and then eventually move the long it's on the turner. I have no idea what I'm doing wrong but it's disappointing 😔
Daughter_of_the_King that is frustrating.. not sure if you can push the cup on your holder a little more.. or wrap the ball with a towel or something to make it tighter... that will help with making the cup level.. also don’t forget to ensure the table itself is level.. good luck!
Check the level of your tumbler turner, same thing happened to me
I know I’m late but what causes lumps and bumps besides the decals?
I keep getting the rings of epoxy on tapered cups! They are level. I have checked and checked. Not sure why! Is it the taper causing it??
Thanks this video was very helpful. If you get a fish eye would you just apply another coat of epoxy?
Andrea Zavala yes that would be correct... any pin holes or divets/fisheyes - I apply another coat of epoxy.. washing the area (alcohol wipe) or a very light sand will ensure adherence if the fisheye is due to something on the surface (contaminants/ fingerprint)
I’m doing my very first tumbler ever, and I was getting discouraged because whenever I would sand my cup it would scratch the epoxy even though I was sanding lightly. Nobody else’s video explains that it’s Normal when sanding.
I’m SUPER new to epoxy. So new I’m in middle of my first project & after the first coat, there were bumps all over. I’m doing pens, not cups, but I figured same rules apply. Thankfully I did sand after the first coat & wiped down with alcohol then did a 2nd coat. Then found this video 😆. I was just gonna throw it away but I decided to wait it through to see what happens after the 2nd coat. If I still have bumps, can I send again and do a 3rd layer of epoxy? I plan on trying again this weekend with another pen to see how it works & see if I can get it better, this set is just my test run.
There is no issues with doing more layers...
@@whatifnc5617 Thank you. Hopefully the bumps are smoothed out. When I checked them lash night before bed, they didn’t seam to be as noticeable. But it’s good to know that I can do another layer if needed.
@@jessicamarsh9779 one year later..... I bet you have done many many pens and you are a pro now!
Thank you so much again for ur help!
I have another question for u tho lol. If you make a glitter cup with chunky glitter on it and a lot of it keeps falling off can you apply mod Podge or something before putting epoxy on it to make sure it stays in place or just epoxy and see? Thanks again!!!
Yes you can use mod podge or there is a glitter spray adhesive in a can that can be sprayed over the cup prior to epoxy... or the multiple layers of epoxy... all of these methods work... just make sure your mod podge is really dry before the epoxy layer
I sanded to much off the rim and some of the glitter came off. What do I do?!
How do you avoid bumps in the bottom of the cup? My cup doesn’t sit level and it irritates me!
Hey there I’m new to this whole Tumblr thing crafting which I’m starting to enjoy. Thank you for the video I really appreciate it but I just have one question after you send it down what do you wipe it down with? Is it just regular wet paper towel or is there something special I should use? Thank you so much.
It was a paper towel with some isopropyl alcohol
Thank you, very helpful 😊. Can I ask where did you get your turner from?
It is from Absolute Programming.. unfortunately he closed his Etsy shop and doesn’t sell them anymore.
Great video thank you! Do you have any tips to avoid dust or little fibers from landing on tumblers while drying?
Hi! I would just ensure that there isn’t anything blowing air towards the cup turner… I,e, fan or vent. And place it in a room where there is no one moving around in the room…. Example - I tend to out my final coats on late in the day - so that they dry overnight while everyone is sleeping.
@@whatifnc5617 thank you very much! I actually always do them overnight and did think about the AC vents being one of the reasons I have issues. I ended up purchasing a large plastic storage box and it worked great last night ❤️
What is an epoxipen?
Thanks for the tips! Is there anything that you could wipe over your final coat that will remove tiny imperfections and not dull your finish?
mindy geist not that I have found... if you find something - let me know!
Hit with 2500 grit sandpaper and then buff it out.
John Jorquez - I have tried that with not too good of results... thinking the type of epoxy is critical
I have a cup that I epoxied and it has loads of little wells where there is no epoxy? Just dry glitter, It was covered and when I checked it, it has all these open spots? Do I have to sand it or can I add another coat of epoxy ? What would have caused this?
2072leb.. sorry for the delayed response... just got the notice! You can just put another coat over the top of it... I see this when too thin of a coat of epoxy is put on.. or if it has too many bubbles in the mix.. let the epoxy rest a little and put.a thicker coat on the cup!
Hi i had an issue with flooding with glittering a tumbler. using the epoxy method.. Basically i have a slick surface and random spots that look raised and the glitter is dry.
Not sure how to fix it. If i can fix it
Elizabeth Sanchez - can you email me a picture.? would love to help but need to see what you are describing... whatifnc@gmail.com
I sanded a cup to get of bumps. There’s white streaks like you mentioned in the video. A friend told me to clean that area with alcohol before I re-epoxy. The cup looks dull in the area that I sanded. Is the cup ruined or will another coat of epoxy have is glossing again?
Yolanda Reason another coat of epoxy will make it shiny again... it is not ruined....
What do you do when your doing a chunky glitter and you sanded it down but it turned the glitter a white ???
What kind of glitter do you use? I've seen other videos and they stress using higher quality poly-glitter, not craft glitter. Good luck!
I am just starting and have attempted my wood grain cup 3x. I have gotten wavy looking epoxy do you have any idea as to why this is happening? It is right off my vinyl decal. It is pretty substantial so not sure how to fix it. I’m feeling pretty frustrated.
Not sure if your wood grain is the vinyl or if you have done a wood grain from alcohol ink.. I put a light coat of epoxy over my alcohol ink woodgrain, let cure.. then apply any vinyl, then final coat of epoxy.. if it is an entire cup covered in vinyl.. it could be that the vinyl isn’t adhering smoothly all around the cup.. and ensuring that the cup is level to the table is crucial... I have found full vinyl on cups to be very temperamental
Just found your video. Still learning. What grit sand paper do you use? And what epoxy are you using? Again, thank you 😊
I usually just pick up an assorted pack… but use 120 or 220 the most… just be cautious that you don’t sand down too far and ruin your design…. Hope this helps
Also I use Alumilite epoxy… just started using the quick dry with awesome results!
Look what popped up for me... hi there friend...
Ha!!! Hi Laura!!!
Hi, should we wait until it’s completely dry and not tacky to begin the sanding?
Yes I would wait until not tacky
hi, so I am so new to tumblers but love making gifts for birthdays. Attempt went bad lol. I added just glitter and to many coats of epoxy now. So when I tried to sand I can't get to the lumps of glitter. Any suggestions, or do I have to trash this one?
@@4stroke1000 smart thank you
Hi my question is about a glittered tumbler. After my first coat of epoxy and sanding, can I place my decal and then apply second coat of epoxy or must I apply second coat, then decal and another coat of epoxy after the decal thus making it three coats?
If the surface is smooth, you can apply the decal and then a second coat… good luck!
I'm trying to do my 1st ever tumbler & my tumbler looks like Freddy Kruegars face. Can you tell me what I did wrong?
If my bottom isnt flat after the second coat of epoxy can I heat it with a heat gun and flatten it or do I need to sand it?
Amanda Laino... sanding is the best option... heating cured epoxy doesn’t work... will affect adhesion to the cup and will not give results you are wanting
Hello I had raised bumps on my glitter tumbler I sanded them down and now my glitter has some dull spots do I put more glitter then more epoxy or do I just put more epoxy which in turn will bring back the glittery look?
Just putting on epoxy will return the shine.
I have a question. I been struggling to find a cup holder. I've looked for a football or even type of sponge but nothing seems to hold the cup at a straight angle. What will you suggest? Thanks in Advance.
I used a thick pool noodle and put a level on the end of my cup to check it
Hello Your cups are beautiful and I’ve been wanting to try forever and just did but didn’t turn out so great so far lol so I was just wondering if you could help me. I just attempted to make my first glitter tumbler and I just put the first epoxy layer over the glitter last night and i now see that it did dry and it nice and clear but there are little hard round bumps literally all over it like the whole thing is super bumpy they look like teeny tiny little balls I wish I could show you its hard to explain and when I applied it last night there weren’t air bubbles all in it so what is causing this? I’d really appreciate it thank you so much!
Boogie Baga ... it is the glitter causing the bumps... any glitter that isn’t flat will cause lumps.. a light sand in a well ventilated area (be careful not to sand too far down as to remove your finish) then another coat of epoxy... i have had some chunky glitter cups that have taken 3 coats of resin to get smooth
Ok I’ll try that tonight!
The bumps look like clear little balls under the epoxy so glitter can even cause that type of thing? I used the pink Spin it Brand glitter because it looked so pretty and I was so excited to try this I’ve been wanting to forever but ugh I’m not so good at it I guess lol.
So sweet of you to get back to me tho I really appreciate it!
Thank you so so so much for your help!!!
I wish there was a way to show you a picture it’s not lumpy at all it’s smooth with little hard clear raise ball type sticking up things all over it. Sry I’m trying to explain it it’s really hard to explain lol it almost looks like little tiny clear plastic balls or something fell all over it while it was drying ugh so hard to explain sry
What did you whipe it with? Coffee filters and alcohol rub?? Or not
fatima arcaro -probably paper towel and 90% alcohol
Do you sand until the leveled epoxy is the same height as the bumps?
I sand the bumps down to be level with the rest of the cup’s epoxy... hope that helps!
I have a problem with my vinyl lifting in corners once I apply the epoxy. How can I fix it?
If you are not using permanent vinyl you need to seal it. I seal mine either way because I don’t want to risk it lol I am fairly new but someone told me to seal with mod podge or clear spray paint.
I am having pits in my cup I need help even trouble with the resin can you help p!ease
Where did you get your turner?
Renee Newcomb - from absolute programming - he has an Etsy store... here is the link. www.etsy.com/shop/AbsoluteProgramming?ref=simple-shop-header-name&listing_id=651966395&ga_search_query=absolute%20programming
"Level" on the top side or the bottom side? If it's level on top, it's slanted on the bottom, causing epoxy to run towards the base of the tumbler. Also, you showed us the tumbler with the epoxy lump on the base due to uneven tumbler on spinner, but you didn't mention how to correct it once that dry.
Hello! My tumbler has only 2 areas with bumpy glitter do I need to sand the entire cup or just those areas? Thanks
Just the bumps areas is fine
I have the opposite problem. Fisheyes in resined, alcohol ink tumblers. I’m prepping correctly- washing them well, then spraying with 91% alcohol and then spray painting with a flat or primer, allowing 24-48 hours to dry, then applying epoxy etc. How do I get the resin to stick on a second coat in those holes without sanding?
I have gotten fisheyes when I try to put in too thin of a coat of epoxy... it can also be from a fingerprint or contamination on the tumbler after you have completed the alcohol ink... I try to not touch the cup directly after finishing... use the turner handle or wear gloves...
So to fill in those areas... you can just apply a drop of epoxy into the void/fisheye.. allowing it to stick to the epoxy around it... after it cures - then sand lightly and apply a coat over the entire tumbler...
If you catch it while still curing the first time... put a small drop into the void then... I look for these types of imperfections after turning an hour or so... best of luck!
Thank you!
I’ve only been making playing with epoxy for a month or so and haven’t mastered the lumps and bumps 🤪 I need to get better at sanding and going slow. My problem is that I rush the steps out of excitement to see a finished product and then it’s no bueno 🤦🏻♀️
napalaylasmom I totally understand! It will teach you patience.... I usually put the on the turners overnight... so it isn’t like watching paint dry!
nchuskers1 I learned the hard way to put my cups on the spinner at night 🥴 My 3yo got too close and did a little flick of her head and a bunch of hair stuck to the cup and I had to give her a haircut 🤦🏻♀️ 🤪
@@MrsNosbig Oh MY!!!! I have gotten in my hair too - by leaning to close to look at something... baby wipe and a little alcohol rub got most of it out!!
We tried the baby wipes but she was screaming and I had no clue what to do other then get my hair scissors 😆 Luckily for me I cut my family’s hair (thanks UA-cam tutorials) so it wasn’t a complete botch job
I have the same issue
I’ve epoxied a tumbler that I alcohol inked. Even though it seemed like an even coat of epoxy, as it dried it seemed to pull away in spots. When dried, it was all lumpy and bumpy even thought the tumbler itself is smooth. I tried doing this twice with the same result. Do you know what is causing this? Some of holes are quite large, 1/4” in size so I don’t think it would have been air bubbles?
I have found if I don’t apply enough epoxy I will get open areas... or it will pull away at the rim. Hope you were able to correct your creation!
WhatIfNC I changed the brand of epoxy I was using after heart many complain about the spin it brand. Worked perfectly, first try with different brand.
My mugs keep mushrooming at the bottom - trying to keep that from happening
Check the level of your turner and the cup on the turner…. If a large amount pools to the bottom… it is all about cup angle
How can I quit getting big bumps on my tumbler?
Kelly Hadley is the bump is around the entire cup toward the bottom or top... it is that your Turner/cup are not level.. if it is random bumps.. applying additional epoxy later in the drying process can also lead to bumps. Glitter cups tend to be bumpy on the first coat... I apply a thick 1st coat, that can be sanded smooth and then apply a second coat. Hope this answers your questions
How do you deal with lint? I have scoured the room I epoxy in and can not get a completely lint free environment it seems. Is there a way to remove the tiny lint bumps? I have sanded them and applied as another coat of epoxy only to get lint bumps again! So frustrating....
JenifferG 1974 a few questions....1j where is the turner at... I would check where you have the turner positioned... make sure you don’t have a fan or air register nearby that would blow directly on the cups... also a low traffic area helps..
2). How are you applying the epoxy? Just making sure you are not using a brush of some kind that might produce lint
3). How long are you leaving it untouched before removing from turner? Make sure your epoxy is cured (not tacky in anyway). I have picked up lint or fingerprints by removing too soon.... for my setup and epoxy I leave at least 10 hours (overnight).
Hope this helps!
It is about 4 feet away from the fan which is blowing away from the turner.
I apply with a silicone brush or my fingers with nitrile gloves on.
I leave it over night or a minimum of about 8 hours usually.
Thank you for the tips. I will maybe try just leaving the fan off to see if that helps.
Im having the same issue! Cleaned area, not much happening in the room. Looks great when epoxy is on, i come back later it has lint throughout 😭!
Hello. How do you prep a plastic cup with vinyl before adding epoxy?
I am sorry I haven’t attempted to apply epoxy on a plastic cup... I only use stainless steel tumblers.. I would be concerned that the flexibility of the plastic will cause your epoxy layer to fail....
Do a light sanding over cup start with a thin layer of epoxy
What to do if the vinyl got epoxy onder it and dry with vinyl sticking out😢
Depends on how bad… If it is like letters… I have trimmed off the part sticking out and a light sand.. put new vinyl on to fix the lettering and another coat of epoxy…. To prevent in future… make sure vinyl is adhered really well on all edges… a few tips are
1) have a good surface to apply vinyl… I will put a thin coat of epoxy over painted or glitter surface first and stick vinyl on it..
2) wait longer (several hours) after putting on vinyl before applying epoxy I have less issues..
Hope this helps!
Today for the first time my epoxy 5 min after mixing felt like gum. I was like WTF now it's lumps everywhere 😤😫😭
Hey! Could you tell me what I’m doing wrong and what should I do if the epoxy won’t stay at the top of the cup around the rim?
Check the level of the cup on the turner and the machines level.. this happens when the cup is angled away from the rim.. it can be very slightly out of level
@@whatifnc5617 thank you!
What grit sandpaper?!?!?
I use an assorted pack... usually 120 grit
I always sand between layers. But always my last layer I end up with bumps still. I have such a hard time with bubbles. I even use a heat gun…
Have you tried letting your epoxy settle a little after stirring?? Sometimes letting it sit for 5-10 minutes reduces the bubbles
@@whatifnc5617 yes i do that. I’m wondering if it’s just the epoxy I am using.
@@tiffanysavoie4847 I use Alumilite Amazing Clear Cast, but recently started using their Amazing Quick Coat.. I buy directly from them as the quality from big box stores doesn’t feel the same… not sure if it is storage or length on the shelf… IMO
I am really liking the new quick coat!
I have a bump on bottom how do i fix that
Sand the bump down or shave off with exacto (if possible)…. Recoat with thin coat of epoxy to finish
