Epoxy resin - casting technique to get rid of air bubbles - no pressure pot needed

Epoxy resin - casting technique to get rid of air bubbles - no pressure pot needed. In this video I will do four trials to show off how to improve your epoxy casting quality and reduce air bubbles in your resin. This will work for jewelry making, or any other casting needs.
Attention please! Thanks to this awesome community, mainly Pam from Highlandboxes ( check out her awesome channel here - / pamharris101 ) it came to light that I was using incorrect proportions when mixing my epoxy. On my Epoxy it actually says it's 1:1 volume ratio - hence you can't use scales! Just use two containers with the same amount of part A and part B. There are also epoxies that have 1:1 weight ratio so please read the description of your epoxy carefully so you don't make the same mistake as I did! Pam thank you again for pointing this out!

Casual DIY do you pour it in by 5’s?

[@nicoleknight5801]

Thank you so much.

[@RealSkoolmaster]

Pro Tip: Use a kabob (small Round stick) to do your mixing. Flat, things like popsickle sticks, introduce air despite your mixing action. The resin rolling back in introduces air. A round mix stick will do the same job but introduces MUCH less air. Using heat + round stick+ slow stir + flaming the stream during the pour I have attained crystal clear results (same resin) without a pressure pot.

[@CasualDIY]

Hi, that is a pro tip thanks! Need to get some 😁

[@RealSkoolmaster]

best place, at least in my country, is the grocery store (market?).

[@CasualDIY]

@@natraz823 hi it's a good tip for slow setting epoxy but it needs a hefty investment in the equipment. And usually the time needed to get air bubbles from epoxy in a vacuum chamber is much longer. Some epoxys can't be put in the vaccum chamber either as it will impact on the chemical reaction in the epoxy, so it's worth checking the full information booklet on the epoxy you have👍

[@sergioagodoy8357]

Do not use wood stick because tend to absorb part of the component and the rough surtace retain part of them too. Use glass or plastics stirrers

[@CasualDIY]

@@sergioagodoy8357 that's a good tip, thanks👍

[@kokeskokeskokes]

My two cents: Mix the two components inside a plastic bag having all the air squeezed out the top prior to mixing. You will not get a single bubble. Just punch a hole in the bag when you are sick of kneeding and gently push the stream of epoxy wherever you want it to land. No bubbles, no clean up, no sweat.

[@CasualDIY]

Not seen that one before, got me intrigued🤔

[@kokeskokeskokes]

@@CasualDIY I guess I have done too much epoxy mixing in my project. All were small batches > 1 g apiece so using cups became quickly uneconomical because of left overs. I started cutting plastic bags into squares intended as lining and it evolved from there.

[@CasualDIY]

@@kokeskokeskokes very cool idea mate

[@perseus6852]

I'm gonna try your method and see how it goes. Seems like homemade vacuum chamber! I'm working with large molds and the torch is not enough to burst the bottom bubbles.

[@kokeskokeskokes]

@@perseus6852 Awesome.

[@mercedesmarton3768]

For those who buys resin in a larger quantity (gallon) I recommend you to get from the dollar store condiment bottles. Either the colored ones (red and yellow) or the clear bottles. Way easier to control how much you pour when measuring. Also if you use small amount at the time (like making jewelry and such) get clear medicine cups. They are clear, and they are perfect for measuring. Whatever is left on the bottom after use easily pops out the cup and you can reuse them over and over.

[@resinAce]

That was a great experiment! With Alumilite Amazing Clear Cast resin I find it pays to try and not introduce any bubbles to begin with, by using a thinner mixing stick (bamboo skewers cut in half), don't stir too fast, and keep the stirrer in contact with the bottom of the mixing vessel. I am so good at it now I can mix a shot glass without a single bubble :D

[@CasualDIY]

Great tip thank you. I actually got some toothpicks that should be just fine?

[@resinAce]

Sure, for mixing a shot glass they should work a treat :)

[@marcelthomassen3152]

Thank you for posting your video, I make batches of around 8 - 10 gram and I basically do the same as you (trial C) but I do another step after that. I use a syringe (without needle) to suck up the epoxy and poor it onto my products. By doing that it is as if the remaining bubbles go to the top of the syringe, you can see them very well and I just stop the syringe when the bubbles come close to the bottom. Then I suck up again more epoxy. The second advantage is, that you can dose very accurately and bring the epoxy at the place you want it to be. I clean the syringe afterwards with acetone, it works really well.

[@CasualDIY]

Good tip thanks for sharing I may check that out 😁👍

[@marcelthomassen3152]

@@CasualDIY Maybe I should explain better. When I suck up the epoxy in the syringe, there are no visible air bubbles in the epoxy, but it is as when the epoxy is sucked through the small syringe opening that creates some “tension” in the epoxy and that activates the tiny (invisible) air bubbles to “clump” together to become a bigger visible bubble that stays in the top of the syringe, especially when the epoxy is “pre-heated” so it is thinner.

[@rothery2]

Might want to redo this and add a pour to it, since most people mix in one container then pour into another. Using a High thin pour helps get rid of many of the bubbles introduced by mixing.

[@CasualDIY]

[@Chris_Wolfgram]

I only caught this, because I'm new to this, and made the same mistake myself on my first little trial. It still worked okay, as a I guess a touch more hardener is okay, while a touch less probably would not be. Anyway, you can still mix epoxies by weight, you just need to know the specific densities and calculate accordingly. Epoxy is about 15% heavier than hardener, by volume.

[@minimarket8567]

You can and should use a scale. Weigh the A and B bottles fresh out of the box and use that to determine the ratio. For Alumilite I multiply the A weight by .8 and it cures without fail.

[@timrockman7]

I most often used one ounce batches that were specified to be 1:1 by Volume and I would very carefully measure out the hardener and resin by eye. Then I weighed them precisely and determined the ratio to mix them in grams...To the nearest second digit on my scales. Works beautifully and you can do some math to figure out larger and smaller batches. You can use scales conveniently if you know how many grams of hardener to use with X grams of resin.

[@sergioagodoy8357]

One thing that has to be considered when using by volume o by weight, is that always one of the component is more viscous than the other, so when transferring one onto the other you always will have remaining part of that component in the vase. The best system is by weight where you weigh one component, tare of the scale and add the second component carefully and you will have always the correct proportion.

[@JohnChuprun]

A word of caution, make sure you use a slow setting epoxy. Heat will exponentially increase the reaction velocity, so be careful heating it once mixed. The pot life on the datasheet will be half that time or less depending on how much heat you expose it to, which as it sets will make it more difficult to pour - introducing more air bubbles, etc.

I use Amazing Clear Cast Resin. I simply throw both of the sealed bottles in a sink full of really hot tap water for about 10 minutes, then dry the bottles (a must do, so a stray drip of water doesn't fall into the resin), then mix & pour as usual. I'm also careful not to mix the resin too quickly so I won't be so apt to introduce air into the resin. I rarely have bubbles but if I do, I quickly hit them with a heat gun.

[@anitaschilder]

Your part A is quite thick. When that happens to me, due to environment temperature, I put the whole bottle in hot water. This way it's much easier to get the right amount out of the bottle, it mixes a lot easier and it reduces bubbles. Another thing you can do is use a mug or candle warmer. It's like a heated coaster. After mixing put your cup with the mixed resin on the warmer and leave for about 10 minutes. All bubbles will be gone. I wouldn't use the kitchen lighter until after you have poured your resin in the mould you want to use and after you have added any fillers you want to use like glitter, shells, flowers, etc. Usually you'll get some bubbles after adding these, especially flowers and shells will do that. So it's best to use the lighter at the very end before you leave it to set. I usually check again after half an hour to see if more bubbles have come up (again, you'll see this often when you use flowers and shells). If you see any bubbles after half an hour, use the lighter again but hold it a bit longer on the area with the bubbles as it will soften the resin which has started to get thick by that time. When you do that, you won't be left with a crater where the bubble was but the resin will level again. Another thing you can do is when you use a mould with sharp edges and corners, use a toothpick and glide it along the bottom edge in the resin. Often bubbles will sit in corners or edges and they're not always easy to see. You'll only notice it when you take your finished project out if the mould; you'll have some sharp edges holes in the corner and edges and sanding is the only way to get rid of it then.

Squeeze the air out of your epoxy bottles before you flip them. That way air doesn't mix inside the container before you even start the pore. I find poring onto the popsicle stick releases the bubbles during mixing. Always remembering to pore and mix them slowly. I always use heat as well even if I cheat a step. I never tried warming my epoxy. Good tip I'll give it a try.

For something that small I'd recommend polyester resin. A bit cheaper and smells a lot funkier, however I've found that even with vigorous mixing no bubbles appear. Polyester resin also polishes up to a much more glass like finish over epoxy.

Great video. I think if you find a longer curing resin the air bubbles will have more time to escape. You can use a small heat gun to warm up the mix after both a and b are mixed together. The resin should be almost water like, as there is no need to use a torch. You are dealing with vapors toxins and flammable materials please read the msds before using heat on epoxy... Wear a mask use ventilation and keep the epoxy away from sources of heat.

[@timrockman7]

A couple tips for you to master this craft, Mr. DIY: 29 C is better for your ambient shop temp. I heat my epoxy work room studio, and soak my gallon container epoxies in hot water for whatever time it takes to make them fluid and workable. 85 F is ideal. For my epoxies that works out fine and if it is warmer than that, I need to work quickly because they generate heat on mixing and harden fast. Wood will soak up the resin because wood is porous and has air in it, and guess what comes out? billions of tiny fogging Bubbles. Fail! Seal your tongue suppressor pine stir sticks with acrylics. Just paint them a couple times. No more tiny bubbles. They can be used many times over.

[@CasualDIY]

Thank you that's some awsome tips👍

[@timrockman7]

You can use scales. I do all the time. Here is how. This is to be done with all the different brands of resins used. Make precise identical marks on the outsides of two identical polyethylene cups. There called 'portion cups'. You can go with larger cups if you want even more precision. Put the Resin marked cup on your scales and tare, or zero the scales. Your scales will ignore the weight of the cups and then measure only the resin by grams to a tenth that you will carefully fill to the mark, and write the measurement, like 12.5 Grams. This is your Holy Guide Number, and you must record and inscribe it everywhere. So now you did this with both your resin and hardener you have two numbers like R-12.5 Hdnr- 11. Pour them into your mixing cup and do your resin job. Later if you want to do a smaller project with about half of that last batch. Divide 12.5 and 11 by 2. Whip out your calculator. Or tell Siri to figure it out for you ;-) If you want to do 50 countertops of a huge bar or restaurant with that resin using huge amounts of resin, just mix 12.5 Gallons with 11 gallons of hardner. It's that easy and so much fun. Mor later.

Cheers mate. It all depends on the epoxy you use. The one I'm using now doesn't smell at all, or I'm that used to it now ;)

[@guygorget1429]

from my experience, epoxy does not stink, but polyester doooooes a lot!

[@WirelessDesigner]

component A and B in cup B and Cup A ....! confusing, maybe next time you can call the cups 1,2,3 and 4 :)

[@TopFurret]

using a scale is an amazing idea to get equal parts of resin!!

[@TJFNixon]

TopFurret it’s gives equal weight, which doesn’t always mean equal parts.

[@Unicornenergyshop]

TopFurret doesn’t work with all resins as hardener usually weighs less than the resin thats why measuring is important

[@PSage]

Tom & Melody are both right, but that's not quite the whole story. Some resins are specified with their ratio in volume, while others specify it in weight (some don't even use equal parts, but that's a beside the point). Using the wrong method of measuring a given resin will - as the others explained - generally give you less than ideal results. Except when they give you disastrous results. Or when you get really, really lucky... but I don't know much about luck.

[@robira1313]

Instructions say 1 to 1 by volume. So 4 grams is going to equal 4 grams. Whether it is part A or part B.

[@phallca]

Great vid thanks for sharing. I'm curious about how much it can be heated, and was thinking if it were heated to its maximum usable temperature more of the expanding air bubbles should rise to the surface and give a clearer end product.

[@CasualDIY]

I wouldn't recomend using anything than hot tap water. Resin is a termoseting chemical and introducing too much heat may actually damage it.

[@phallca]

K. Thanks for the reply it was just one of those light bulb moments, trust me to get a dud bulb lol.

[@CasualDIY]

@@phallca lol 👍😁

[@glenmcarroll]

These ideas are a start, and lots of good tips in the comments. Epoxy mixing is by volume not weight. The two parts have different specific gravities. In larger amounts this will be a problem. I am building a vacuum pot for videos I have seen on KZbin. Surprisingly simple. Cheers.

[@drincmusic2769]

This entire time I've been trying to figure out how to not have air bubbles in the epoxy for my special project when I should have thought that that really doesn't matter as long as there's no fractures in it.

[@AngelasMixedMediaArtist]

Thx 👍🏻👊🏻

[@CasualDIY]

No problem 😁

[@radhikagrover2446]

Hey! I saw that in test D uh used blow torch for removing air bubbles....Can we use heat gun for the same ? Wont it burn the plastic?

[@CasualDIY]

With the heat gun or blow torch you have to be very careful not to burn the container or resin. You only need a second of heat to go over the resin to pop the air bubbles, it comes down to practice and checking what works for you I guess👍

[@theresabraddock9310]

ive never done this before but I was wondering if you put the stick in first while you pour your mixtures inside... Im thinking this because I think introducing the stick afterwards is actually what is adding the air.

[@spiritwings4592]

Wood anything makes air bubbles

[@k.r.9606]

I warm my resin before hand and work under a heater vent, I pour in small layers and take bubbles out with a lighter ad whatever I need to then pour again popping bubbles as I go. I check it every 5 minutes for about 30 minutes to pop more bubbles and make sure nothing moves. I use a .9mm pencil lead to shift things back (Cleans easy). I also use small plastic stir sticks and stir each resin part separate for a minute before adding them together.( The bottle says too)

[@CasualDIY]

That sounds like a bubble free process very demanding tho

[@robira1313]

How do you clean pencil lead out of uncured epoxy?

[@k.r.9606]

@@robira1313 I've never had it leave any lead behind or had it make marks. So I'm not sure, maybe use a tooth pick?

[@anlcansakalloglu741]

Thanks

[@mrsrobson7417]

What about using a heat mat instead of a water bath? The moulds themselves could also be sat on the mat?

[@CasualDIY]

Never used anything like that but could be an interesting option.

[@tinywarhead7037]

Would this work with sorta clear?, it's a silicone for making molds, I got a ton if bubbles in my mold

[@CasualDIY]

Not sure not used it.

[@tinkmarshino]

Tom.. you keep your garage at in house temps? even at night? Well not bad.. but how would you do a large batch? say for a table or display cube? a lot of work, a lot of room.. vacuum or pressure I think is still better for a larger job.. This was impressive never the less and I think you are on to something.. keep experimenting and refining the processes.. thanks for the share, carry on, be safe and have fun..

[@CasualDIY]

Thanks👍 I think the resins for "river tables" and large pours are design to self de-gas but still certain conditions need to be kept. With resin it's a must to keep good ambient temperature unfortunately👍

[@tinkmarshino]

@@CasualDIY Well I thank you for your information.. every bit of knowledge helps.. Carry on my friend..

I really and truly thank you for being so nice,and the site you gave me which sells resin only serves Europe countries,and I am in Suadi Arabia,again thanx and my best regards,,Badr.

[@CasualDIY]

You are so welcome!

[@dotto6974]

Just wondering if this makes an affect if I'm going to pour into mold after?

[@CasualDIY]

Yes it will, I if pour carefully it should give you better results

[@rima1815]

Thank you a lot, I will try It tomorrow. I am losing to much time when I put the resine, had to take off bubble one by one with small metal piece...take me 5min. I just have less bubbles than you because I mix it with round piece (your flat piece of wood creat a lot of bubbles).

[@CasualDIY]

No problem hope it will work for you 👍

[@alaskanmal]

Nice video and explanation, I am just getting into resin pouring myself, I would be interested in seeing a video of a much bigger mix and you using your trusted method of getting air out, and pouring a project, the very small pour that you showed in those little cups is not really what a good example , just my thought.

[@CasualDIY]

Hi. I'm actually producing a series of videos about some basics about resin. I get what you saying about larger pours the trouble with that is it takes a lot of resin which costs a lot of money. And I just can't afford to just do it for the video and currently I don't have a project that would be that big. But stay tuned it may happen in the future👍

[@thetresureofdragonsbis6065]

after you pour your mixed resin into a mold put it over a lamp with a wire cookie sheet(cookie cooler?) over the light bulb, the light must be facing up or it won't work, this makes the resin set faster and thinner as it sets so you have even fewer bubbles, this works really well unless you are using a closed mold, then the bubbles get stuck at the top and it makes swiss cheese-like plastic, I've never tried taking the bubbles out before i pour it in a mold, i let you know if its still cheese

[@CasualDIY]

Interesting technique 👍

[@himikoichikawa6893]

for anyone doing the water one do not try using hot water from a thermos i used it it worked fine for my first cast i did but my second one it cured within 10 min or nearly cured i was shocked. btw first time making it so yea >.> hope it helps

[@timsmith894]

Would using some kind of vibration plate/ on a very low setting bring the bubble's to the top ,then pop them with heat, just my thoughts 🙂

[@CasualDIY]

Already tested that with mediocre results

[@badralnejaidi4596]

nice job buddy .

[@CasualDIY]

Thanks 👍

[@toddharrison2213]

You are very good at explaining things. How about a video on ways to remove bubbles you don't see until after it cures?

[@CasualDIY]

Thank you. I think the best method for that is the pressure pot👍

[@toddharrison2213]

@@CasualDIY I realize that is good for preventing. What about after the resin has cured and you want to salvage it rather than pitch it and start over wasting more resin?

[@Masters.of.101]

Hi friend this is Harmeet Singh you doing a good job please share with us a cheeper amount to spend to get a great results hope you understand byee

[@sunilkumararickattu1845]

Kindly explain as a bottom line what mehod eliminate/reduce the bubble either with place on boiling water or similar way to avoid confusion

[@CasualDIY]

The best method I found is test number 4 but only very hot tap water. I wouldn't recomend boiling water it may be too hot and damage your resin
