Tips for working with epoxy resin

Originally published January 2012.  Updated August 2018.

Whether you’re new to epoxy resin or a seasoned professional, these hints will be helpful to you working with epoxy resin:

How does epoxy resin work?

Epoxy resins come in two parts: the resin and the hardener. When the two parts are mixed together, a chemical reaction occurs that causes heat production.  This heat changes the epoxy from a liquid to a solid.  Epoxy resin, like other resins, is mixed together in a specific ratio or amount of resin to hardener.  There is a pot time to the resin (period of time that the resin is still liquid enough to work with) versus curing time (the amount of time needed for the epoxy to completely harden).  Each epoxy resin is different!  For proper curing, the resin needs to be mixed thoroughly in the correct proportions.

If you are confused by these terms, please check out our resin vocabulary article.

What safety precautions do I need to take when working with epoxy resin?

  • Follow manufacturer’s instructions and safety precautions.
  • Work in a clean and well-ventilated area.
  • Depending on materials used, strongly consider wearing a respirator, rubber gloves and eye protection.
  • Follow manufacturer’s recommendations for clean up. Dispose of all waste materials in accordance with local regulations.

Read more about working with resin safely.

How should I prepare my crafting area for working with epoxy resin?

  • Cover the work area with wax paper. Resin will not stick to wax paper.
  • Prepare a level surface for items to dry on that will not be disturbed.  (And speaking from personal experience here…watch out for the cat hair!!!)
  • Have boxes or domes available to cover your resin projects while they are curing.  This will keep out dust and other contaminants.

What if I want to include things in my resin?

  • To prevent discoloration and water stains, seal both sides and edges of the image.  This is especially important if the image is printed on an ink-jet printer. Allow the paper and sealant to dry completely before covering the images with resin.
  • Glue the image to surface to prevent “floating” and possibly trapping air bubbles which may show up later. Let adhesive dry completely before adding resin.
  • Resin magnifies images and makes them surprisingly clear. Make sure your paper is exactly the way you want it.

What about embedding other items in resin?

  • Flowers and other vegetation need to be dried before use.
  • Seal dried flowers, candy sprinkles, etc., with a spray sealer to prevent discoloration.
  • If using resin dyes or pigment, add a small amount at first. Generally, a little goes a long way.

Be sure to read our article on how to seal papers or other findings for including in resin.

Do you have any resin pouring tips?

  • Apply the resin a little bit at a time. Depending on the resin, it can pour quickly. Pouring from a smaller cup is easier to control.
  • Leave a bit of resin in the bottom of your pour cup.  You can then check the resin in the cup to check to see if your resin is cured. This way you don’t have to disturb your project to see how it is curing.
  • A heat gun is great for removing bubbles from your resin.

I am new to this whole thing and I have 1000000 questions haha.
When you pour the resin into your mold and you have a laminated picture, how do you get it into your project? Once it is poured do you just lay it on top and it will stick or if you glue it how do you keep the glue from showing and when do you glue it? I have just bought products to make coasters with kids pictures in them. PLEASE give me STEP BY STEP instructions after mixing so say start at the pouring stage PLEASE and THANK YOU!!

Also, what type items can I use for molds? We need around 300 for Vacation Bible School projects? I need a very cheap mold to do a coaster or possibly something along that size?

Hi Diane!

When using a laminated picture, trim the lamination away close to the picture edge, but not right on it. This little bit of a border will still keep your picture sealed and keep the resin from creeping in, but will still be clear (invisible) in your casting.

Do you want the picture to be on top of your finished casting? Where you want it when you are finished will determine when/where you place it as it relates to your mold. If you are pouring into a mold with the idea that you will pop the resin out and the part touching the inside of the mold will be the top, then you will want to pour and add your pictures in face down. (I know this comment sounds confusing. You’ve inspired me to make a video to cover the topic.)

As for cheap molds in bulk, I would suggest trying a restaurant supply store. You might be able to get some implements there. Do you know a restaurant owner? Buying their food in bulk also means they get lots of containers with lids? You might be able to use them. Experiment first though. I don’t have any concerns that the resin will cure in it, but I worry about you getting it out (use some mold release) and how it will look (the resin will take on any textures in the surface). I am also going to post this topic in the forum to get others to comment. Look for it under ‘how can I ….’

H! Don’t know if this is too late for you or not, but, JC, you can make your own molds with a bake-able clay like Sculpey and a product caleld Amazing Mold Putty which you can buy at any Hobby Lobby or, I believe, Micheal’s. For example, say you want a square pendant. Simply make a square out of clay, bake the clay to harden it and then use the mold putty to capture that square base for you to pour in your resin. Hope this helps! 🙂

I’ve seen silver jewelry were colored resin is “floating” between the silver strands to create a stained glass look. How would you go about this? Could you somehow use wax paper as a backer then remove it once the resin is cured?

I have been enjoying working with resin but I have not yet been able to find out how to avoid the rim that forms on the outer edge of a piece of work in a flat mould. I have tried sanding it down but it takes an age and is not a good finish. I would appreciate comment on this please. Many thanks.

Reply
Katherine Swift

Sheryn,

What you’re experiencing is the effect of the surface tension of the resin next to the mold. (I don’t the exact physics here…) You will need to sand the edge down to get it even.

Hi Katherine,
I am working on a sign for a friend that will be primarily outside, in the FL sun. It is a metal sign and I’ve painted it with Acrylics. I also want to glue paper designs to it. I need to use something that will keep the water out and also not damage the paper designs. I have been all over the internet and am not sure how to go about it. Do you have any suggestions? Is resin the way to go? Should I not do the paper designs at all?

Hi there, If i were to print the image with my ink jet, what paper material am i supposed to use?

Reply
Katherine

@Yen,

I like to use a bright white paper, not necessarily photo paper. (In my experience, the images on photo paper will sometimes smear, even with glue). Regardless of what paper you use, you will need to seal it before embedding in the resin.

Reply
Katherine

@Tracey,
Hmm. I don’t know that resin is the easiest choice here. Since it is going to be outside, I would suggest using either polyurethane or polyester resin. Both will cure hard, however, they each have disadvantages. The polyester resin is cheap, but will yellow with exposure to UV light. (It will happen quickly in FL!) The polyurethane is pretty durable, but can be downright crabby to work with in Florida (and is a bit more expensive). Polyurethane hates moisture (humidity included)! The only way I could get polyurethane resin to consistently work here in FL was to use it in a room that was completely sealed off with the dehumidifier running. I had to get the humidity levels under 50 percent for it to work. Regardless of which one you choose, be sure to take the proper safety precautions.

Hoping you can help me as I’ve scoured the net looking for answers and fixes with no success. The craft I was making was a candy toilet seat for my bathroom. My husband and I followed the instructions in the book I have, watched tutorials and researched the dickens before just diving in to make the seat. In spite of following the instructions, something went horribly wrong. The reaction was so bad that parts of the mold actually melted and warped and some of the candies literally cooked and melted.

After letting it set up, I was able to take the seat out of the mold and in feeling mold, there are ripples and some bubbles in places where the reaction was intense it melted the plastic. To say I was disappointed is an understatement because we followed the directions and can’t figure out where it went wrong. The first two layers went fine. It all seemed to go kablooey in the last pour/set up.

Do you know if I attempted to try the seat again, will the ripples be able to be sanded out so the seat is smooth as it should have been or is it a total loss on that part of the mold? If the seat part is a total loss, do you know of anyone who sells just one piece instead of the set? In your experience, can you explain as to why this reacted the way it did and if reattempted what should be done differently?

Appreciate any input as this project has been a huge disappointment.

Hi there, I want to coat a table top. I have yet to decide whether I will set a picture or actual items in the resin. In any case, I’m not sure how to control the flow of resin of the edges of the table ? Do I just let it run off naturally and sand it down after or is there another method ? Appreciate any advice. Many thanks.

Reply
Katherine

@kevin,

Put a ridge of high quality masking tape around the edge of the table. The resin won’t stick to the tape and you will be able to pull it away once it cures. You may have to do a little bit of sanding to get off the grainy appearance once you’re done.

My house has beautiful brass decorative backplates on the interior doorknobs but there are a few missing. Rather than replace them all with something new, I’d like to try to make matching replacements for the missing ones. I’ve been reading about resin and I’m thinking about using clay to make a mould from an existing plate and then making new plates with resin. I plan to paint the finished pieces with metallic spray paint. Do you think resin is a good material for this? Any suggestions?

Reply
Katherine Swift

@Courtney,

Yes, resin would work well. I would suggest a polyurethane resin for its durability and lower overall cost for the amount of resin you’re going to need. (As a side note — you can color the resin with metallic coloring — no need to paint them!)

Hello- I want to attach transparency paper to the top of a thick glass paperweight- can easycast clear epoxy resin be used to adhere the paper? I plan to brush it generously underneath, place the image and let it cure, then a second application of resin over the top of the paper to coat and reduce the seam. I have already worked with the same paper – embedding it in bangles with success – but never with glass. Unable to find confirmation on this site or elsewhere- any help is appreciated.

@Gina Marie, I have never done what you’re describing, but resin does stick to glass. I think it should work here.

Hi. I have a problem with micro bubbles. I use epoxy resin as a sealant between my pendant trays and images, and a coat between my image and glass cabochon overlay. My problem is this: Even when I get ALL bubbles out with heat (this includes first using heat on the layer of resin between the pendant tray and the image, and then again on the layer of resin between the image and the glass) and all bubbles are gone, after the resin starts to cure (about an hour or so into the process) dozens of little micro bubbles appear under the glass. By this point in time, the resin is too tacky to press on the glass to get the air bubbles to just seep out the sides (where the glass ends and the edged of the pendant tray begins) and removing the glass just ruins the image, and I have to re-pour all over again, only to have the same problem when the new layer starts to cure. Is there a way to prevent these micro bubbles from forming? Or should I using something other than resin for this job?

Reply
Katherine

@Kaitlyn, I would suggest using a good glue instead of the resin for what you’re trying to do. Normally, these microbubbles would pop and you wouldn’t see them, but the glass cabochon is keeping them from escaping.

Hi Katherine! I love your site! I’ve never worked with resin before but I am pretty crafty and refinish and upcycle furniture and home decor for a living. I’m entering a county fair Upcycling crafts contest. I’m going to take a stack of old Vogue and Harpers Bazaar magazines and make a stool or a kids chair out of it and I’m hoping pouring resin over the stack will be enough to stick the stack together so that it becomes one piece . Can I then screw in a piece of plexiglass on top and bottom or will it crack? Should I brush it on or pour it? I’m afraid pouring will make a “puddle ” at the bottom? Lots of questions sorry but If you could start me in the right direction it would be most appreciated! Thank you!

@Lisette, I’m not sure the finished product will be stable. I’m thinking you would have better luck decoupaging the magazines over an already created form.

hI Katherine i hope you can help me. I too am having trouble with microbubbles. I make pendants using E6000 epoxy to seal my inkjet printed photos onto glass cabochons. I have had only two successful runs. The rest have been plagued by bubbles. No matter how hard or light I push they form either right after i mate them or not long after. I use glossy photo paper and glaze the back. I don’t seal the photo itself but haven’t had any trouble with inks running. I was wondering about everything from the humidity to the quality of paper. I’ve even tried uv epoxy with the same results. I’m desperate because people want my pendants and love my designs but I need to find a solution before I can make a strong go of it. Hope you can help.

Hi Katherine I was just wondering if you could help me out because I’m a year 12 student and currently am planning my body of work (final artwork). I am looking into doing sculpture or a collection of works and I want to see if I can use resin along with coral pieces and shells to create my own kind of reef. I have no idea of how to use resin or what it actually is and what effects it has on organic materials. I’m thinking of experimenting with it to try and recreate sculpture pieces like these: http://www.shonawilson.com/artwork/2014/

I was casting some gems for a costume and the surface of a few of them are tacky while the rest of them are perfectly fine. They all came from the same pour so it’s not a ratio problem or I’d be experiencing it in all the gems. What would get rid of the tackyness? Would covering it a clear coat of spraypaint work or would it harm it?

@MK, if they are just a little sticky (like touching the surface of tape), then yes, a clear coat of an acrylic based spray paint should be fine.

I am making resin pendants and earrings. I seal the images with modpodge and glue to the bezel base leaving them atleast 24 hours to dry before pouring the ice resin. 2-3 hours into the curing process, microbubbles appear in the resin (looks like dust). Can you please advise on potential cause and solution? Thanks in advance.

Reply
Katherine

@Kim, I would suggest checking your pendants frequently (every 15 minutes or so) after you pour them to remove those bubbles. As resin cures (and subsequently heats up), sometimes bubbles are produced.

@Kim, my suggestion would be to try warming the bezel with a heat gun, then pouring a bit of resin. Make sure all the bubbles are out of that layer before pouring more. Warm again with a heat gun to get any additional bubbles to rise to the surface.

Hi Katherine
I’ve tried a few castings with different embedded items and have found that plastics and such work fine for me, but I have encountered a thin layer of ‘bubble’ it’s more of a film of bubble around a small sculpture of grey fiberboard…now it looks like some kind of surface tension thing. In places the resin has soaked in slightly to the board and so bonded nicely, even though it has made the board darker. But in other places the resin doesn’t seem to have adhered and that there is a thin layer of air between sculpture and resin.
I’ve seen a similar thing with some rough wood splinters Ive tried to embed. Is there something I can coat the fiberboard and wood with to prevent this film?
Many thanks for your time and experience.
Chris.

Hi there, I have an old beautiful monkey pod wooden coffee table from Hawaii that I am looking to refinish. Its from the 50’s and the main issue I’m faced with is that the existing topcoat which I believe to be a epoxy resin has seen some wear and tear over the years and I have chips, scratches, a couple cracks…. all of which are in the topcoat, not the wood that I want to correct to make the table look beautiful once again. Whats the best approach to tackling this? Do I fill the cracks in with epoxy resin and then sand it after its cured to blend into the topcoat, then after that step pour on a brand new top coat? Am I missing anything here? Also, can a oil based sanding sealer be used on top of the old topcoat before I begin sanding to help smooth things out and make the sanding in preparation for the new topcoat be easier? Thanks and take care!

Reply
Katherine Swift

If I were going to try this project, I would sand down/off the top layer of resin such that all the defects are sanded out. Be sure to end with a very fine grit of sandpaper (1000 or higher), otherwise, you will see sanding marks when you pour the next layer of resin. I would then put on a new top coat. I would not use an oil based anything on the resin. Resin can be a little crabby with things like that.

I am coating wooden chopping boards with resin, but I’m finding small air bubbles are forming, (after removing the normal bubbles with a flame torch), that it’s too late to get rid of them, then I have to sand and re-pour!

I’m using liquitex gloss medium varnish over the acrylic ( no bubbles form there) and on the wood where the bubbles/gas forms.

Reply
Katherine Swift

Hmm. I’m not familiar with that product. Perhaps two to three coats of it before pouring the resin? My thought is that there bubbles that are being release during the resin curing process. I suspect that while the resin is heating up, it is drawing more bubbles to the surface through the liquitex. Maybe another couple of coats will keep the bubbles sealed in.

Reply
Katherine Swift

I doubt it, unless you are working in an oven. 😉 Is the wood very porous?

Bridget

It can get very warm.. If the resin sets to quickly can it cause this reaction with the wood. The wood is sealed and it doesn’t seem porous at all when I coat it. I’m stumped. I’ve just poured an acrylic mix with resin on the wood and it worked beautifully. But the resin by itself on the wood.. Is proving to be difficult.

Katherine Swift

Assuming your resin is as close to bubble-free as possible when your pour it, my two thoughts are that either the resin is reacting with something or trapped air is being released later. So it’s not bubbling if you put the acrylic layer on first? I’m not clear when the bubbles are occurring.

I am looking to make a hanging faux stained glass window for privacy in the window inside my shower. The window does get a damp, but not soaked, and gets a few hours of sun per day.

I am thinking of using plexiglass as the base. My plan is to sand the plexiglass, wipe it down with rubbing alcohol to remove any oil and dust and apply self adhesive led strips for my outlines, then pour eyeshadow tinted resin to make my “glass”.

Can you suggest the best resin for this project?
Will it need to be sealed with something to protect it from dampness?
Any advice at all is most welcome!
I’ve never worked with resin before, but I’ve always wanted to and I can’t wait to start!

Reply
Katherine Swift

I haven’t tried anything like this, so I’m afraid I can’t recommend a resin. I would expect resin would adhere to the plexiglass, but I don’t have any experience with it, so I don’t want to tell you for sure that it will work. You will also need to find a way to adhere the LED strips to the plexiglass to make sure the resin doesn’t leak underneath. I wouldn’t expect adhesive strips to be enough of a barrier. Since you are new to resin and this is an ambitious project, I would suggest this blog post for reading as well: https://www.resinobsession.com/resin-frequently-asked-questions/resin-jewelry-making-what-every-beginner-needs-to-know You are going to need to attack this project in small steps, doing experiments along the way, before going after your large scale idea.

I am planning on doing a craft paper counter top as part of a kitchen remodel. I really want to use epoxy instead of a polyurethane type sealer.

Can epoxy be brushed on those edged and then just poured on the flat surface where it will be more vulnerable to wear?

An epoxy is going to go on thick and will want to run off the sides. You may have to use a polyurethane sealer on the vertical surfaces, then use an epoxy on the horizontal surface.

I am planning on glazing deer antler slices with easycast epoxy resin. I have a few questions regarding the application. What would I use to glaze just the top? I have seen people seal their objects with easycast using a popsicle stick. I dont want to leave any brush marks or bristles behind. So would the stick be good if I use the resin sparingly? And another question, the bone of the antler is not very porous but the dried marrow in the middle is very porous. What can I use to seal it before I apply the resin? I want to avoid the micro bubbles.
I’m also planning on trying them as open back bezels. I carved out the marrow and sanded the inside bone. Will I have any issues with bubbling? Or should I just seal it to be on the safe side?

Hi, Katherine. Thanks for replying.
No, I don’t have a way of suspending them to glaze them. I never even thought of that honestly. Do you have any ideas? I am going to test on a few extra slices that didn’t come out even just to see how the resin will act as a glaze.

Reply

Unfortunately, I don’t have any great ideas to suspend them. I’m thinking it would be great to have them hang upside down such that the resin could drip off the points.

Hey. I just seen your question. I use naturally shed antlers as open back bezels and I’ve never had an issue with bubbles and I’ve never sealed them. I just poured in layers. Let each layer cure for 24 hours. Also, I use Scotch Heavy Duty shipping tape. With every other tape, it’s either left a bumpy finish where it was sealed or, with the cheap brand shipping tape, the glue on the tape fused with the resin and left it cloudy.

Thanks so much for your response, I really appreciate your input. I’m currently using 40 mm semi sphere molds and first I pour the polyester resin/catalyst, then I grab a dandelion by the stem and slowly immerse the flower in until the bottom of the flower hits the base of the dome. Then I’m left with the remaining part of the dandelion and stem sticking out of the top which is the flat side and will be the underside of the finished product. I plan to mount the finished product onto a bezel but when I take it out of the mold it is very irregular shaped because it is hardened around the jutting out stem and remainder of flower that didn’t fit in the mold. bits of dandelion are sticking out.

Duck tape tends to be too sticky (for me anyways). I would suggest a good quality, wide masking tape instead. Cheap masking tape won’t stick and duck tape has too much stickiness that it ends up making a mess. The resin will take up the surface of the tape, so there will be a bit of a frostiness to it. You can either recoat with another layer of resin, sand it down, or use a couple of light coats of our resin gloss sealer spray. https://shop.resinobsession.com/collections/tools-and-supplies/products/castin-craft-gloss-resin-sealer-spray

Thank you so much Katherine. I will try the wide masking tape per your suggestion. I would just like to skip the mold stage if possible. I wonder how that blue painter’s tape or the frog tape would do – maybe leave less residue …

I am pouring resin over ceramic tiles to make coasters. After they cured, one of the coasters produced one bubble! (erg!) Instead of sanding the bubble and repouring resin, is there a way I can just ‘touch up’ the bubble spot, after sanding of course? Thank you!!!

Hello, I wanted to ask a couple questions about epoxy resin.

Would I be able to spray Epoxy Resin with a paint gun on a rounded “etched” glass surface?

Is the epoxy toxic?

Thank you!

Hi! I would like to create an abstract art piece on canvas. I’m mixing each of my acrylic paint colors in separate cups with epoxy resin and doing a free hand pour of each colour. Is there a particular type of oil I can also drop into some of the colors to make “cells”? I’m *very* new at this! I would like to create my own piece of artwork for my home. Thank you.

I am gluing a photo (on glossy photo paper) into a locket for a necklace. Do I need to do anything to prep the picture or can I just lay epoxy on top of it to seal the image onto the locket?
Is there a certain type of epoxy I should use for this type of job? Thanks….

Reply
Katherine Swift

You will need to make sure your image is well sealed before adding the resin, otherwise, it will show ‘water’ stains after casting. We have a few other resources about this on our blog: https://www.resinobsession.com/?s=sealing+papers Any epoxy should work well for this, but a doming epoxy (one that will produce a dome over the surface) is what I would use. This is a guide to the resins we sell, including which are doming resins: https://www.resinobsession.com/wp-content/uploads/2015/09/resin-choices-april-2016.pdf

Can I use Modge-Podge to seal a photo printed on glossy photo paper to seal it? Does it need to be sealed on both the front and back or just the front where the epoxy will be applied?

Reply
Katherine Swift

Yes, Mod Podge will be fine. A minimum of two coats, front and back, then glue into the bezel. Allow at least 12 hours to completely dry.

Reply
Katherine Swift

Provided the furniture has been properly sealed so as not to take up moisture, yes, it will work.

Hi, I am making a bar top, using 3/4 inch plywood and pallet boards on the top of that will be the surface. I will then nail an edge. What can I use in the seams so that I don’t lose epoxy when pouring? I was told Vaseline.
Thank you.
Scott

Reply
Katherine Swift

You can use Vaseline, but you won’t have an easy way of getting it out after you pour the resin. I would suggest taping the seams with a good quality masking tape. The resin won’t stick to it and you can remove it after the resin has cured.

You need a cylinder shaped template to make your mold from. As for the flower, it needs to dried and preserved before adding to the resin.

Hi! I’m new to this, and I wanted to use epoxy to make jewelry. But, my family got 2 part epoxy for tables or other large surfaces. Will the epoxy for the tables work the same if I use it for jewelry?

Reply
Katherine Swift

It depends. If you are using it in bezels, then it will work, although it may not be as crystal clear as jewelry quality resins. If you want to use it for molds, it won’t be easy. Tabletop resins mix quite thick. It will be difficult to get out the bubbles.

Hi! I’m new to resin and your blog has been really helpful. I just poured epoxy resin into a mould, but I’d prefer to fill it more! After a 72 hr cure, can I just mix some more and pour right over the first pour? Will I have to sand the first layer, or will it be alright to skip that and just pour directly onto the smooth resin? thanks in advance!

You can go ahead and pour that next layer. No need to sand unless there is a blemish you are trying to fix.

This post on our blog will help you do the math on calculating how much resin you need. https://www.resinobsession.com/resin-frequently-asked-questions/how-much-resin-do-i-need Once you put the resin on the side, it will want to drip down. I don’t know how well the sides will get coated. I have not done a project like this before, but I can share that ‘sparkly’ stuff like crystals and mirrors will not be as sparkly once they are under resin. It has to do with the light not refracting like it does when it goes through air. (There is a physics explanation for it, I just don’t know what it is. LOL)

Hello, I have a big concern.
i tried using resin hardner mix on canvas after watching tutorials of resin art on youtube. All of them used plastic glasses to mix the color and the resin-hardener mixture. My problem is that when i mixed the resin hardener with the color in plastic glass, it was fuming hot and boiled, dissolving the plastic glass, spilling all the mixture out and fuming. It was horrific experience, i don’t know why it happened. Can you please guide me ??? I really want to paint some interesting concepts with resin art but i feel unsure about what i should change in the process because the last one turned out to be a science experiment. 😛

It sounds like you mixed up more than the recommended mixing amount and things cured too quickly. I would suggest getting in touch with the manufacturer to get their recommendations on the maximum amount to mix at once.

Any advice on applying resin to spray painted surfaces?
I’ve been trying to spray paint some bottle caps, affix an
image and then fill with resin. Trouble is the spray paint
keeps leaching into the resin and causing discoloration.
I’ve tried spray painting a coat of varnish over the inside of the bottle caps to try and seal the paint before applying
the resin. Although leaching is much less, it’s still
happening and driving me mad! Not sure if this is a solvent on solvent issue or what? Starting to think it might be a
better idea to make moulds first and then affix them using modge podge or something rather than pouring the resin
straight into the bottle caps. Any thoughts or advice would be greatly appreciated!

You can try to put some two-part, five minute cure epoxy underneath there to get it to glue back down. However, I’m concerned it won’t work since resin didn’t stick the first time. It sounds like something is acting like a mold release and is keeping the resin from bonding.

You need to use something to act as a barrier. For example, resin won’t stick to wax. A thicker clear plastic could work in this case. Thin plastic wrap (like for food storage) might melt with the heat of the resin.

You can do it this way, but you will still get bubbles underneath the glass. You need to use something other than resin to glue your pieces down, preferably, a glue you can completely brush onto the back.

Hi, I’ve had a look through the feed and can’t find a similar question so apologies if this has already been answered. I am making resin pyramids with a mix of crystals, copper and aluminium shavings added. I’m using a silicone mould and following the instructions for quantities however the finished product does not look smooth. Some parts are lovely and shiny and some parts are rough. I’m not sure where I’m going wrong. This has happened on all but my first attempt! Naturally, the added materials sink to the bottom of the mould but I have seen others where they are more evenly spread throughout the whole piece. I don’t think these are poured in layers as I’ve seen those too and they look altogether different! Thanks in advance for your advice!

Read through many posts not sure if I saw this above. I’m trying to make a heart shaped resin mold. I have a heart shaped piece of wood that I’ve hot glued corks onto and placed large nails around the edge to form “walls” to which I’m going to wrap wax paper/masking tape around to form a quasi mold. Then I’ll use an AL foil pan to press against it to make the walls firmer before adding the resin. I know I’ll be in for a fair amount of sanding but I couldn’t find an easy heart shaped container the resin won’t stick to. This heart is then being attached to a frame for hanging. Is this all crazy or does it sound possible.

Ok, I zero idea how to resin and stumbled onto this site… I have a weird question and hope someone here can give me some ideas.

My cat passed away last month and I have her ashes. I have a “small dog tag urn”, but honestly I haven’t worn dog tags in a few years and I know I wouldn’t wear it all the time…

So, I purchased a watch compass… What I’d like to do, is remove the compass part (which will require a dremel) and now I’ll have a “pocket” in which to place a little bit of her ashes. I am thinking I can then seal the now exposed part with resin and then seal the protective cover permanently (this is a Sun Company Wrist Turtle, you can get a idea on Amazon).

I only take my watch off when charging it and this way I have some small part of her with me 24/7… I am welcome to thoughts, suggestions or ideas…
