What kind of resin should I use? – Choosing a resin

what kind of resin should i useOriginally published March 2013.  Updated May 2020.

If you are asking yourself ‘What kind of resin should I use?’, you have come to the right place.

This is one of the most common questions I get asked about art, jewelry and crafts.  There is no ‘one size fits all’ resin, and there are MANY things to consider.  I will walk you through how I look at the process, whether I am creating for myself or helping another artist choose a resin.

Let’s imagine you have walked into your favorite butcher shop.  You tell the meat cutter at the counter that you want a steak and ask what kind you should buy.  One of the responses you’re likely to get is a question asking “What do you want to make?”.  Choosing a resin is really no different than this situation.  To be more specific, I would frame my response into “What are you hoping the end result to be?”

If you’re a beginner, I cannot stress here enough that you need to start with an epoxy resin.  Why?  Relatively speaking, epoxy is the ‘easiest’ to work with.  It generally doesn’t require wearing a respirator mask and tends to be the most forgiving of environmental factors, such as humidity.  Epoxy resin also has the longest shelf life.  I also like that it generally has the longest pot time (approximately 20 to 40 minutes to work with it), so it’s great for beginners that are still fumbling and getting used to working with resin.

So you may be asking yourself, “What kind of epoxy resin should I use?”  Once again, it depends on what you want your final casting to look like.  Here are a few other things to consider when choosing a specific epoxy.

Clarity:

If you want your final project to be clear, you want to make sure to start with a clear resin.  Also realize that clear doesn’t necessarily mean ‘color free’.  Some clear resins will cure with a yellow tint, depending on the brand.  If you’re unsure about how clear the resin is when cast, check with the retailer or manufacturer before making a purchase.  Know that the clearer and more color free the resin, the more it will cost.

Fill a space or coat a surface?

Are you trying to cast the resin into something, or are you wanting to put it on as a coating?  If you want to place the resin on something without sides, you want to be sure you are using a doming resin.  This kind of resin is a bit thicker and has the extra surface tension to make sure it doesn’t run over the sides.  Know too though, that this resin being a bit thicker, is also more difficult to remove bubbles from.  If you want to fill a mold or space with sides, you want to use a casting resin.

Of course, each has its own specific advantages and disadvantages, so if you’re a beginner, read this article about the differences between these two types.

So if epoxy is so great, why would I use anything else?

Unfortunately, epoxy resin can’t do everything.  Relatively speaking, it can cure soft.  You may have noticed that when you cast epoxy, you can sometimes dent your fingernail in the finished casting if you try hard enough.  Polyester and polyurethane resins both cure very hard.  When fully cured, they can have the hardness and clearness of glass.  In fact, both can be polished to a high gloss with a polishing wheel and the appropriate compound.  Many epoxies cannot withstand the heat produced by a polishing wheel and will turn cloudy on the surface.

I know what you’re thinking, “Oh my gosh, this is exactly what I need!  I hate having to do all that extra stuff to epoxy to get it glossy!”  Sit down, I have a few downsides to share with you.  First polyester and some polyurethanes may require that you wear a respirator mask with them.  In my opinion, polyester resin will literally take your breath away the smell is so bad.  I would NEVER cast this resin in my house or a space that I needed to occupy in the next 12 hours.  When I do resin polyester in my studio, I save it for the last thing in the day.  I cast, then leave for the day or I will even cast it outside, weather permitting.

Polyesters do have an advantage over epoxy in that is it generally cheaper and is great for casting deep molds.  However, polyester resin has a short pot time (generally 8 to 10 minutes) and the surface exposed to air during the curing will remain tacky.  You can either sand this side down or coat with resin gloss sealer spray once cured.  If you think you might want to cast polyester resin, here are five things you should know about using polyester resin.

Polyurethanes, on the other hand, generally have fewer curing issues and there is a lot of options when choosing one, but you should know that they are VERY moisture sensitive.  If you’re going to venture into casting polyurethanes, you need to make sure to use colorants specifically designed for them.

So here’s my breakdown of how I use resin:

I use epoxy for everything unless I am trying to cast something larger that I want to have a shiny gloss finish.  In that case, I use polyester because I can polish it on my buffing wheel instead of using the gloss sealer spray or coating with another layer of resin.  I like polyurethanes when I need a casting quickly that doesn’t need to be clear or transparent.

In case anyone else is a painter and is interested in what I use to coat paintings – I use Environtex lite and it comes out beautiful every time. I have coated small paintings as well as large 3’x4′ ones. Not a great idea to do on a wrapped canvas as pooling occurs.

What is the difference between Environtex lite and Clear Polyester Casting Resin by Castin’ Craft? I am a painter and I am looking into what’s best to coat my canvas paintings. Something that will give it a “glass topping” look. Thanks!

Katherine Swift

The Envirotex Lite is an epoxy whereas the Clear polyester casting resin is a polyester. You can use the Envirotex Lite, although it cures with a slight amber tint. It isn’t my first choice for artwork coating. You definitely won’t want to use the polyester resin as the surface that is exposed to air can remain tacky after curing. I would suggest the TotalCast resin. https://shop.resinobsession.com/collections/resin?page=2 We only have the small size of it currently, but expect more of the larger sizes next week.

Hi Katherine!

I’m looking for something to coat on already finished jewellery pieces, sterling silver and titanium steel rings with cubic zirconia stones to prevent the stones from falling out.

I would like this coating to dry crystal clear so as not to affect the shine of the metak or stones.

Do you know o any coating that would do this?

Thanks!

Katherine Swift

You want the resin to go over top of the stones? I ask because that will make them less ‘sparkly’ because the light will refract differently doing through a coat of resin first.

Orchid

Loved the details u gave so minutely about resin n its types Katherine. Thanx for sharing all this info. Do u know the answers to these Qs?

1- Hw to get UV protection in resin? Any method?
2- Details about silicone resin and acrylic resin? Pot time, cure time, sensitivity, temperature, etc?
3- Hw to clean the pot n brush used to mix n apply resin? Can the same pot n brush be used again for resin mixing n application?
4- If ease release spray is not available then what can be used?
5- If we apply resin on half side of surface n then after drying apply on the other half side, would there be a seperating line formed between both sides after drying or curing of both sides?
6- For the 2nd coat, only waiting for drying is enough or should wait for 7 days until entire curing of 1st coat is done?

Katherine Swift

I’m happy to help! Here are answers with numbers that correspond to your questions:
1. To get UV protection in resin, you need to buy it that way. That notation should be included in the product listing. If you don’t see it, ask the manufacturer.
2. Every resin is different in terms of pot time, cure time, etc. You will need to get the specifics from the manufacturer of the resin you want to use.
3. We have a video on our youtube channel showing how to clean resin:

https://youtu.be/17Ixaa0Lw6o

4. Vaseline can work as a release, but it may leave marks on your casting.
5. Yes.
6. Waiting until the second coat is dry, not fully cured, is sufficient for applying a second coat.

What is the coverage (sq ft) on the Total Clear Resin 70 ounce kit?

The big differences between epoxy and polyester rein is the expansion and contraction under temperatures changes. Polyester is more brittle and is more sensitive to temperatures change, meaning will crack easiy. Epoxy has more options and types.

Katherine Swift

Hi Tracy, unfortunately all resins are going to yellow with UV light exposure. While that video shows experimental conditions, it cannot account for every experience resin may face when used in a practical setting. While I think the results can be used as a guide, users need to understand and test the resin they are using to see if it’s going to work for their specific needs.

bubbles…some of the clear brands are bad for bubbling…so you have to get out the alcohol burner..pressure pot or whatever way to fight the bubble war. Then again some products don’t bubble as bad.

I just wanted to point out that you should still be using a respirator/mask of some sort at least (I’m not an expert so maybe stick with a respirator) when working with epoxy resin. It can still irritate your lungs, especially if you react to it! Check out Epoxy is Not My Friend on Facebook.

Im a beginner to resin and want to embed bottle caps and make some coasters. I had the Easy Cast-which was prob at least a year old, and worked well. Low bubbles and nice and clear. I ran out, so I bought the Envirotex Lite-pour on. This is not as clear and full of bubbles. Is this the wrong type of resin for my project? What brand would you recommend or how can I clear up all the littles bubbles the muddled my coasters? Thanks!!

The best remedy for those pesky bubbles in the use of a blow torch. Works in instantly. removes them like magic. Just swipe over quickly. I’m told using a straw works good too.

Reply

The Envirotex is really meant to be more of a coating. It was probably too thick for the mold. Unfortunately, there is no way to clear up the bubbles in a casted product once it’s cured. The good news though is that East Cast works very well for coasters.

Hi Katherine,

Sorry I am posting this here, but I can’t get my computer to work on the forums….(something I’m doing wrong, I am sure).
I am trying to figure out something to coat some flat copper or brass blank sheets with. I’m going to use these as bases to pendents which I’m gluing random items onto. Since the flat metal sheet bases I’m using are unfinished I figured it would be nice to coat all of, or at least the back of it with an epoxy resin so that the person wearing it wouldn’t get an allergic reaction or have the piece tarnish due to sweat if the back was touching their skin.
Do you think epoxy resin would work for this?
Thank you so so much for your help!

Thank you so much for the response Katherine.
For Renaissance wax, if I were to use it on raw brass or copper – do you know how long it “stays” for? I’m assuming it wears off over time, is that an accurate assumption on my part?

Thanks again. You are the most helpful person I’ve found on the internet. And it’s a big world out here!

I’ll for sure be using this store in my near future.

Kristina,

I have used the Renaissance wax in the past to seal my sterling silver and resin pendants and have been quite pleased with the results. I always suggested to my customers that they clean with a soft cloth and a mild soapy water if necessary. I would suspect putting a good grease cutting soap on the pendant would take the wax off. I suppose with regular wear it would eventually need recoating, but I can’t tell you exactly when that might be. Glad I could be of help. 🙂

Hello Katherine,
Based on the comment above by Kelly, I am thinking that the Easy Cast is the best for my project because I am trying to cover a table top with bottle caps, but I just wanted to double-check it will hold up as well as a polyester one, that sounds like it is harder?? Many thanks!!

Reply
Katherine Swift

Chelsea,

It depends. If you’re looking at a layer of 1/8″ or less, I would go with the Envirotex. It’s meant for table top coatings, so it might be fine for your project. It will show some wear sooner than an table top poured with polyester, but it’s certainly easier to work with.

Hi Katherine

I am using CR20 Polyester Casting Resin and adding a pigment paste to the mixture. I have used the 1% catylyst to the resin and also doubled it as it is only 150 ml tester mould. The mould was then put in a vacuum pot, air bubbles forced out. The results were interesting in both cases..the resin never really became solid…peeling off the brass pen tubes..!!

I then bought some pigment paste from the same supplier as the resin they manufactured. This time it still had not fully hardened under final turning on the lathe.. but was better than first two experiments..

Could the problem be the pigment paste causing problems with the setting agent.. as I use Pearlex Powders to enhance my casts adding pine cones for example ..no problems at all..

I read on your blog somewhere that this can happen with using pigment paste.. If it does can you use powders to alter colour of resin..and does it work as well forming a solid colour..ie Ultramarine??

Thank you

Reply
Katherine Swift

@Ziggy,

I don’t have any experience with that kind of polyester casting resin. My first thought is that there is too much moisture to allow the polyester resin to fully cure. Have you talked to the manufacturer? Since you’re using their resin and pigment paste, I would think they would have some good recommendations for you.

Yes, you can use powder colorants, but unfortunately, you can’t mix two powder colors to make a new color. If ultramarine is what you want, then you need to add a ultramarine powder.

Reply
Katherine Swift

@Kristina,

I would say most any epoxy resin would work for this project. How big is the vessel? I might make a specific choice based upon the volume of resin you need.

As for glazed or unglazed, glazed would be preferable if the unglazed pottery changes its look when it gets wet.

Once resin is mixed, it is inert and shouldn’t cause any problem to your skin unless you are extra sensitive to it.

Also you say epoxy is best for beginners (me), will it turn out clear, glass like without bubbles if im just making simple objects like coasters and coffee bean jar lids, etc. Its so expensive and i dont want to buy the wrong one, lol. These will be items I will sell in my craft booth.
Thank you!!

Reply

@stacie,
You will need to follow the safety directions for the polyurethane you use. Some require respirators whereas others do not. (By the way, just because you can’t smell dangerous fumes doesn’t mean they are not there.) Since you’re a beginner, I will strongly suggest starting with an epoxy resin. The Resin Obsession super clear would be great for what you’re trying to accomplish. It casts super clear and bubbles are almost never a problem.

I am a newbie venturing into the world of resin(jewellery) & after a long search have stumbled on this site. Your answers seem so informative & knowledgeable, I was wondering if you could help me? I have decided to use epoxy resin as I am new to this aspect of craft & its properties seem to tick most of the boxes, however, I am worried that it may discolour, cause irritation to piercings (as it may come into direct contact with them) and ideally I would like to be able to waterproof the finished piece. Are there any varnishes/coatings that would allow the finished product to be hypoallergenic, waterproof & have long lasting colour/clarity? Thank you so much in advance, Kind regards, Hannah

Reply
Katherine Swift

@Katalina,

You will need a strong resin that will be somewhat impact resistant. I would suggest either the Resin Obsession super clear epoxy resin or the Alumilite Amazing casting polyurethane resin. As long as the mold for your case was produced with a shiny template, your casting should come out shiny as well.

I am planning on building a bar top for my Daiquiri Shop. I have purchased 8 foot bamboo poles that I want to lace together and then cast in Resin. I plan on building a large box mold out of melemine and adding my bamboo and then filling it. It will be over 1 inch thick, but the bamboo will fill most of the area. My question is, what type of resin do you recommend for a clear pour and that can be removed from the mold and is halfway durable. Also, do you have any experience cutting a fully cured cast? Can it be cut on a table saw? Thanks so much. Just found this website and have enjoyed your suggestions.

I don’t know of any coatings that would specifically make resin hypoallergenic, but if it has cured properly, it shouldn’t cause an allergy problem for the great majority of people.

I would either try the Envirotex Lite (assuming it’s going to be a thin layer) or I would try the Resin Obsession super clear resin. The super clear resin should hold up fine to prolonged water exposure, but I’m not sure about the Envirotex Lite. It’s great for countertop coatings and getting water on it, but I just don’t know about prolonged water exposure. I would expect it would be fine here, but you might want to try a test piece first.

@Shannon, The Easy Cast should work fine, but don’t use food coloring. Resin doesn’t like water! To do the layers, you don’t have to wait until they are completely cured, just cured enough that the two layers won’t blend. Two to three hours between layers should be fine.

Oh hello!! I really hope you can help me! I’ve spent hours researching epoxies and still am not sure what will work best. I’m leaning toward Hardman Double-Bubble Green, but it doesn’t list “wood” which might be a problem. I am not a crafter, so I need a lot of help…
My 4-year-old daughter (now in heaven) fought cancer for 2.5 years and “earned” a glass bead for each and every procedure she went through. I want to display them on my wall, so I bought a window (the one that would flank a front door). I hot-glued each bead down on the wooden back, and eventually the glass top will sit over it. However, the glass beads come off with a little hand pressure, and I know a few will fall off when the project is upright on the wall (which is unacceptable). Someone told me to cover it with “liquid glass” or epoxy. This project means a great deal to me emotionally, so I can’t mess it up because I can’t go back and get 1265 beads.
So I need a CLEAR epoxy/resin/?/ that will hold little glass beads to a backing that is partially hot glue/partially wood. There ARE wood sides to the project. I don’t intend for the beads to be fully submerged, as there will be a glass window on top eventually. What would you recommend? Thank you very much! (feel free to email me if you’d like.)

I should also add, I’d like it to be a glossy finish, but because some of the beads will probably be sticking up through the epoxy/resin, sanding won’t be an option. (The beads are all different sizes). Again, thank you so much.

Hi Katherine, yes, I have thought about using a different glue. It would just require many hours to pull up each individual bead, pick off the glue beneath it, and reglue it. I should have just used a better glue to begin with. I was hoping to save time by just pouring something over them, but perhaps i just need to spend another 10 hours re-glueing.

Will that E6000 adhesive glue glass to wood? Just verifying!! Thank you for your help.

Hi Katherine,I saw in a earlier post that you suggested Resin Obsession super clear epoxy resin or Alumilite Amazing Casting Polyurethane resin to make cabochons. Are any one of these resins harmful.

@Keshia, Most epoxies don’t have a strong odor, but polyesters do. Some polyurethanes do as well.

@Keshia, I would suggest becoming familiar with the MSDS information on the resins you would like to use. Part of that information includes health and safety guidelines.

I have what may be a goofball question: I’m experimenting with casting for the first time to make Halloween decorations- specifically a lifesize skull that I want to add LEDs to to create a glowing effect. I’m new to casting and on a budget and the prices for resin were a bit of a shock. My question is can I use off the shelf Polyurethane (i.e. clear Minwax) to do this? I have a silicone mold that’s currently curing. Also due to volume of material to fill a large cast, I’m attenpting a mold within a mold- I sculpted a ‘brain’ that I’ll make a silicone mold of and insert inside the skull mold. My thought is that I’ll be using less fill volume (will be semi-hollow) and create a cool 3-D see thru effect. But back to the central question: Minwax is Polyurethane right, so can it be used to cast? I was also curious if the Castin’ Craft catalyst would improve curing the Minwax?

Reply
Katherine Swift

@Rob, Minwax is meant to be a coating (e.g. for a bartop). It’s not meant to be used in a mold. You should also only use catalyst designed for the specific resin. The Castin’ Craft catalyst would not work with the minwax resin.

Hi Katherine! Thank you for your expertise and for sharing it with all of us! What a blessing and a gift! I am new to resin so I understand to use an epoxy. I have an old window. I want to create a 3d effect design by using random broken or cut pieces of glass onto the existing window frame. I’m not sure if I should first glue my pieces onto the window and then pour an epoxy resin over to coat, or if I should first pour my resin onto the window frame and then place my pieces of glass into the resin? Can you tell me your opinion and which resin would be best for this project? Many thanks to you!

Reply
Katherine

@Starr, I would glue the pieces down first. Be sure to coat the back of the piece well with glue so that you have a good adhesion across the entire surface. Doing it the other way would probably still work, but there’s a greater risk of trapped bubbles rising up later in your resin.

Hi Katherine!!! You are fantastic and so informative :-)…thank you for you info and the answers to other peoples questions which where also helpful however I won’t to build a table top (no surface to start with) out of resin and mosaic tiles then later attaching it to a cast iron base…what resin do you recommend? How can I build the surface for it without the resin sticking to it (a box frame covered with wax paper)? How thick should I make it? Will I be able to smooth the edges after it cures? Many thanks for your time 😉

Reply

@Kathryn, since you’re pouring the resin into a mold, I would suggest our Resin Obsession super clear resin. The resin won’t stick to wax paper, but your box is going to get heavy. Make sure it has good support while curing. The thickness is your choice, but you will be able to sand it to smooth out any rough edges after it has cured.

I have attempted to use resin in small molds for jewelry. I used alumilite and it cured way too quickly as I barely was able to get it out of the cup after the instructed mixing time. Is there a resin with a longer working time? A few bubbles are not a big deal to me, but the little bit I was able to get out was filled with bubbles.

Hi Katherine – I am trying to embed objects in a large casting in a glass container, two layers with the object sitting on the 1st cured layer. I am using a Polyester Resin with a Catalyst but am having issues with the casting getting very hot and then discolouring from clear to a yellowish colour.

Hi Katherine~I make replica foods for museums and historic houses, and have long used museum-safe materials like air-dry clays, papier mache, acrylic paints, etc., due to concerns about off-gassing and potential damage to period pieces. Having recently used polyurethane resins for an outdoor food display, I was relieved to see your comment that, once cured, resin is inert. I cast small fish in resin. Once thoroughly cured, they were sealed with an acrylic sealer; painted and shaded with acrylic paints; then given another final coat of acrylic sealer. Do you think encapsulating cast/cured resin pieces in museum-safe acrylic sealers should nullify curatorial concerns about off-gassing? Many thanks.

Hi Katherine,
I will gladly use the Resin Obsession but is it still considered a soft resin like easycast? Even though my coasters look great I can’t see myself giving them or selling them to someone if the first time they use it it’s going to get indentations. Above there was mention of a resin sealer spray, do you think if I spray that on the coaster before the first use it will solve my problem and make it a harder dent free surface?

Hi everyone,
Katherine is the only person I have noticed to explain that easycast is a soft resin that if you try you can easily dent a cured piece with your fingernail. That being said I’m confused as to why most people say it is great for coasters. My coasters look amazing but once I set a glass on it it leaves dents. It’s got me very discouraged because I really like making them. But I don’t like that the dent. PLESE HELP!!!

@Michelle, the Resin Obsession super clear resin cures much harder than the Easy Cast epoxy resin. I have used it for coasters and have been very happy with the results. The resin gloss sealer spray will give you a final glossy finish, but won’t harden the resin.

Hi Katherine, it seems like your the wonder woman of resin and I couldn’t find any reference of people covering CD mosaics with resin so I thought I’d ask the resin guru 🙂
I’m covering a flat table with cut up cds and want a hard protective coating that is clear enough for the cd’s to catch the light in the same way. I tried just a spray varnish but this compromised the shine. The resin also needs to not interfere with the shiny coating as I have learnt grout can (this is my second attempt at this project, I only got up to the grout last time). I think I have narrowed it down to Enviro-tex lite pour on or easy clear cast epoxy but haven’t ruled out Hiflex EasyFlow 60 Polyurethane Liquid Plastic Casting Resin. So…
1) Which, if any would you recommend for a beginner and an under 1cm deep covering and
2) how would you recommend I go about making a mould around the edges to keep the resin in while it dries? (I read the above where you mentioned a doming resin however I have been unable to find any at a reasonable price) and
3) should I use grout with this or would none be better? I don’t mind either look so it’s whatever will work best. 🙂 thank you in advance!

Hi Katherine,
So much thanks to you for running this forum, and sharing your expertise!
I carve jewelry, mostly rings, out of wood. I usually carve tiny settings in them and set semi precious stones using a glue adhesive epoxy. Some of the stones are probably very porous material, and some also break easily. I’m wondering if painting a layer or two of epoxy resin with a brush over these stones will give them a little more strength.
Also, can I do the same on the wood rings themselves?
And if I attach the coated stones to the coated wood while still wet, will they stick well enough to each other as to not fall apart? Or should I coat both with resin..let cure, and then just use epoxy glue to adhere them together? I have no experience with epoxy resin, and am a little worried that resin might interrupt the way that light catches the stones and crystals. Thank you for any advice you can give. Much appreciated!

Hello!
It’s so great to see someone who takes the time to respond to questions!
So as a beginner, I have a few questions. I’m making a large project in which I would like to use resin in three different parts. I’m making my mailbox.
In the first, I have cast iron number pieces that I would like to add colored resin to the inside with purple ink (they are like ivy and don’t have a solid middle and so by adding a colored middle it would make them easier to see). I would need it to dry hard, be uv resistant and have a transparancy.

The second, I am making my mailbox out of stained glass. I’d like to coat it in a doming, crystal clear uv proof, non scratching hard resin so as to protect it more.

And the third I saw online (as you may have) that one table that was made with photoluminescent glow powder poured I to the natural holes? Well I would like to take a wood board, carve my last name into it and pour the resin mix into that.

The big wuestions is if their is a resin I could use for all of these projects or if I would have to get different resins for each? And which polyurethane resin would you recommend? I plan to do these in my garage with the door open and during a dry day (I live in Pennsylvania).
Thanks so much!

You can paint the stones with epoxy, but in my opinion, I do think it will affect the light refraction of the stones. You can use the wet epoxy as a glue (or glue the wet parts together). It will adhere parts well.

@Shawn, With a casting that large, I would suggest going ‘inexpensive’. You are going to have challenges regardless of the resin you use. You will have to pour in layers because the amount of heat a casting that large and thick poured at once will be a lot. You may need to consider pressure or vacuum casting to make sure your casting(s) come out bubble free.

Greetings! I am writing from Brasil to kindly ask for help: I am trying to make a marble dust surface finishing to cover the surface of an open air art sculpture made of concrete plates. The idea is to apply a thick layer of marble dust pre-mixed with epoxi resin, spreading it over the concrete plates surface, and once the resin is cured and dry, to grind it and polish. The tricky thing is that when i mix the marble dust with resin, the marble dust turns grey. I have been using titanium dioxide powder (white pigment) to make it white again, but i feel it comes out less natural then if i was able to preserve the marble dust natural color. I am making several tests trying to make the powder impermeable before mixing it with resin. My impression is that the reason the marble dust turns out darker (more grey than white) it´s because it gets ‘wet’-like, soaked in resin, just like beach sand turns darker when wet. Please help me figure this out, how can i preserve the white tone of the original marble dust when mixing it with resin? I am currently using 40 grain of marble dust mixed with a less thick powder like grain. the idea is that it will shine in the sun the most possible, without using the white pigment (titanium dioxide), preserving the white from the marble grain and dust when mixed with resin. Sorry for the long explanation and thank you tons in advance for the attention. Best, Marcello

Hi Marcello, yes, you are correct in that the dust is turning grey because it is getting wet. The best suggestion I can give you is to try a powder additive specifically designed for resin. We have several powder colorants in our shop that may be of help. http://shop.resinobsession.com/collections/colorants/Powder Unfortunately, I don’t have a good way to help you keep the marble dust ‘dry’ enough so that it looks good when mixed with resin.

Hi Katherine, appreciate your reply.

I noticed writen where it described the diferences between types of resin, that the “Epoxy resin won’t withstand the heat produced by a polishing wheel and will turn cloudy on the surface”.

What if i use a wet poIisher, would that permit me to reach the high gloss with epoxy resin and marble dust? I was figuring the water would keep the temperature lower and not afect the resin..

I don’t know. I’ve only ever used a wet polisher when I’m making my own cabochons from minerals, stones and such. It would be worth a try, but make sure the resin is very hard and fully cured first. If you give it a try, let me know how it goes.

All resins will eventually yellow with UV light exposure. Some have additives to slow down this process so that it takes years instead of months. As for your project, one layer should do it. You shouldn’t need an extra coating unless you want it to be very shiny.

I was thinking of doing a 3mm base layer then 2mm over the photo but im struggling to find definitive answers on how to go about it and i see you are definitely a resin guru, would the base layer need to fully cure so as to sick the photos down before the second layer?

I am making up a Sea Glass and Sea Shell grouping in a OLD Printers Tray. The backing on the tray is fiberboard and I want to fill each section with some beach pebbles. I would like to know what you think would be the best way to adhere them to each section…..glue them in individually …use resin or what would you suggest?

I would probably glue them in. The resin is going to seep through the fiberboard and make it look waterstained in those areas.

Hi Katherine,
Great website! Do you think this would work on brass
porch lights? I don’t have a porch so they really take a
beating.
I heard that the latest thing to protect brass is acrylic
urethane… but I like the idea that resin is so thick. Is this a
crazy idea or do you think it would hold up okay under the weather and very hot Texas summers?

Really appreciate any advice!
Nicole

You would need to use a resin designed for outdoor use. An industrial marine resin would be my choice for a project like this.

I wouldn’t expect it to change the dyed effect of the wood, but I am concerned whether or not the wood treatment would affect the resin’s ability to stick to it.

Hello, I have an acrylic container in which I am displaying sand samples from all over the world. Each compartment of the container holds about 2 cups volume, and each compartment is about 2/3 full of sand. I would like to add clear resin to the top to ‘seal’ the sand in each compartment to prevent so I won’t have spillage or mixing of the sands. I think I’ll need about 2.5×2.5×1 inch volume of resin to top off each compartment. What would you suggest? I’m a newbie and not really prone to detail work….but if need be, I can employ my meticulous engineering husband to the task.

Good morning. Can i use easy cast epoxy resin at the bottom of a coffee cup? Will it be safe to drink from? I want to draw a picture and have it be seen at the bottom of the cup when you need a refill. ;).

Thanks!
