This question comes from Tim:
What would be the best cast resin for filling a one pour hole 8″ round by 4″ deep ???
Will there be shrinkage?
Can a Polyurethane be put on top of this.
- March 28, 2017 at 6:54 pm #8402
A few questions for you:
1. Will you be demolding this casting?
2. Is the 8″ x 4″ hole you are filling inside another object?
3. What are you trying to accomplish with the polyurethane?
- March 28, 2017 at 11:44 pm #8404Tim JensenGuest
Applying to hole in exotic wood table, sealed on bottom. Shrinking issue is to bring resin up to flush
on table surface which the table top coat will be polyurethane or similar.
Will I need hair dryer or heat source if using your super clear casting resin ?????
Thank you for every second of your time concerning this for all who will be educated.
Tim the ignorant…..
- March 29, 2017 at 3:40 pm #8409
First thing I would suggest is to make sure the hole in the table is sealed well. Otherwise, the wood will release air that will show up as bubbles in your casting.
If using the super clear casting resin, if you are careful in mixing, bubbles are almost never a problem. Having a hair dryer handy though would be good as there will likely be a few bubbles you will have to get out. You should know however, that when using the Resin Obsession super clear resin, we recommend mixing no more than 3 ounces at a time. It is going to take you several pours to get your hole filled.
Were you looking at a polyurethane varnish to coat your surface? I ask because I like to use the Alumilite Amazing clear cast epoxy resin as it is considered food safe once cured. https://shop.resinobsession.com/collections/resin/products/alumilite-amazing-clear-cast-epoxy-resin-16-ounces It will give a glossy finish and would be compatible with pouring over the hole filled with either the same or a different epoxy resin. I haven’t put a coat of polyurethane over epoxy resin in this situation, so I don’t know how well it would work.

Hello..Newbie to resin casting here…am wanting to pour a resin table top that will include a burl slab, stones, fossils, etc…am bewildered by all the info online regarding thick casting…can anyone point me in the right direction for the right resin that is crystal clear, relatively safe to use, and I can pour large areas of resin at once?…am confused by the instructions of only mixing 3 ounces of resin at a time…my table top will be about 2 by 3 feet, so three ounces at a time seems like alot of frantic mixing periodically, etc…🤤…help!…lol..and thanks in advance!
- March 3, 2018 at 12:36 pm #12536
Were you wanting to be able to sand and finish the table afterwards or is using the resin the final step?

Hey hope you guys can help, I’ve been looking at scale models (ships) that are particularly imbedded into resin to make it look like water. Is there a certain resin that would suit this type of application? There are water products available for dioramas but can’t be made too deep…
- May 23, 2018 at 2:30 pm #13613
A polyester resin is what I would use in this case. Do you have any experience with them? They can be a bit fussy to work with. We have one in our store here:
- May 28, 2018 at 6:43 am #13676Dave BensonGuest
I don’t have any experience with any resins, what I’m aiming to achieve is a deep water diorama. Maybe a sunken ship, clear resin or slightly tinted blue with a ship on top… but I’d like for the resin to be 200mm deep or 7-8 inch deep… will the resin have to be poured multiple times in the layers?
- May 28, 2018 at 4:35 pm #13705
It depends on which kind/brand of resin you are using. The manufacturer should be able to tell you how much resin you can mix/pour at once. (Otherwise, the resin overheats and cures very quickly.) A seven to eight inch pour is likely going to be a lot of resin. Polyesters tend to do well with this large a pour.

Hello, thanks in advance for the help. I’m making a live edge conference table that’s 8’L x 4’ W x 2”H. I’m not encapsulating the top but rather filling voids and any dead space in the mold to crate a rectangular table that’s flush with the slab. Hopefully I’m describing it right.
I’ve been thinking of using a polyester resin but from what I’ve been told by merchants is that polyester doesn’t adhere as well as an epoxy resin does. I’ve never poured Polyester but all I’ve read says polyester is harder to work as far as smell and cure time. Is there a benefit to using one over the other for my application? Is there a clear epoxy resin that can be poured 2” thick and won’t overheat and crack? Thanks!
- June 10, 2018 at 7:33 pm #13829
I’m not clear, are you casting the resin by itself or with wood?/

I am looking to fill the center of a tree stump that has 3 large branch sections coming off the main stump. I’m thinking the holes i want to make will be 6-8″ diameter and 14-16″ deep. I think i will need at least 3-4 gallons. I will light them from the bottom with some type of lamps. A) what type of resin to get; B) should i keep the resin clear and use multi color changing lights or can i put a little pigment in each hole to make them different color? thanks!
- July 20, 2018 at 11:04 am #14452
For a project like this, I suggest using a clear polyurethane resin. We don’t sell them, but instead recommend going to alumilite.com. Please let them know we referred you. 🙂
You can either color the resin or use lights for your project.

Hi. I have maple wood slabs (between 1-3 inches thick) with holes (some as larges as 4-5 inches diameter) that I want to fill with clear resin, then will finish wood with poly. From what I can see in this thread maybe it would be better to use a clear polyurethane product than one you sell? I have other projects that I think your products will work for but for now I am working on the slabs. p.s. Ive never worked with resin so please provide advice or show me where to find if possible. Thanks!

Hi, I’m new to casting and wanting to make essential oil bottle holders that would be blocks about 1.5”wide, 2” tall and 8” long with holes either cast into the top or drilled. I’d like to use something that I could cast in a single pour so that I can use paints to make a sort of mottled translucent color scheme. What type of resin would work best?
- September 19, 2018 at 11:19 am #15633
Unfortunately, I don’t know of any resin that has been tested to hold oil for long periods of time.
- September 19, 2018 at 3:34 pm #15638RandyGuest
They won’t be holding the oil directly, it’s more for displaying the bottles

Hello. Im looking for some advice on finishing off our bathroom vanity top. I have placed smooth small lake rocks we collected from a beach on top of backerboard and built a form around them. We would like to finish them with a clear seal. Due to different sized rocks i need to pour it 3 inches thick. Its about 10 square feet total. What do you recommend for product to use and how to apply? Thank you.
- October 2, 2018 at 2:26 am #15862
I would use the Alumilite Amazing Clear cast epoxy resin. You can find it in several sizes in our store here:https://shop.resinobsession.com/collections/resin/alumilite
You will want to mix and pour it in several layers as it is too thick to apply in a three inch pour. Don’t mix more than 16 ounces at once.
Since it sounds like you are a beginner, these articles will help you get started:https://www.resinobsession.com/tag/beginner/

It’s going to be hard for you to get it done in one pour and have it be bubble free. Do you have access to a pressure pot?

Hi there, after ~pouring~ over dozens of articles, videos, etc. online, I can’t deduce if what I have in mind is feasible, and if so, which resin would be best.
I’m trying to create a clear, single-piece, 40″x40″x15″ block. Let’s assume a proper mold has been constructed, and also that an infinite number of friends have readily offered their help entirely unprompted.
Is there any material that won’t require numerous layers, each with a lengthy cure? This wouldn’t kill the project in the water, I suppose, but it unarguably complicates the undertaking.
I read that pouring epoxy thickly causes it to heat and cure very quickly, but I’m tempted to think that that would work to the advantage of our theoretical monster block:
E.g. my infinite friends and I mix the total amount of resin needed in separate safely-mixed quantities, and then pour all of it into the mold at once. As long as it didn’t explode or melt the mold, the faster it cured the better. Would it explode or melt the mold?
Is this how any of this works? I apologize to be so clueless. I just want a giant epoxy resin block.
I really appreciate any guidance anyone’s willing to offer. Have a great week!
- December 10, 2018 at 11:02 pm #19793
Here are the things to watch out for as you are doing this project:
1. Yes, too much heat can be a bad thing. It may cause your resin to crack or cure so quickly you don’t have the opportunity to get the bubbles out.
2. You need to find a casting resin that allows you to do large pours at once. (We don’t have one that does this large a quantity at once.) Doing some quick math, you will need 50 gallons or more of resin. Follow the directions for the maximum amount of resin to mix and pour at once.

This is all very helpful information. I’m a woodworking making a clear resin river between two live edge oak slabs for a dining table top, I’m very familiar with the West System epoxy but haven’t used it for this purpose in the past.

- January 14, 2019 at 3:51 pm #26738
If you don’t want a high-gloss finish, you can rough it up with a little sandpaper once cured.

Hi there. I am a total beginner to resin casting so I was hoping to get some advice! I am wanting to make a “diamond” table top. I have a table and bought 4.5mm and 8mm crystal diamond table confetti which basically looks like tiny little diamonds. I’m hoping for a result close to this https://diamond-furnishings.co.uk/product/the-crushed-diamond-sideboard and am wondering what the best resin would be to cast the diamonds in the table top. Thank you!
- April 21, 2019 at 4:02 pm #38851
If it were me, I would only add enough glue to cement down the diamonds. If you completely flood them, they won’t sparkle as much.
Any of our clear doming resins will work as a glue. They are in our store here:

Hey I’m looking to use resin for a gift and I have some preserved flowers and I’m putting them in a glass fishbowl type container and wanted to cast it in resin so the flowers don’t have to be dusted to prevent them from breaking. What resin do you suggest for it to still be clear in the jar

Hello! I’m pouring a resin river table and am looking for ideas on resins that can be poured in large quantities but won’t cost $150 per gallon. I am going to seal the edges of the wood before I do the large pour. But my large pour will be about 4.5 gallons. With a little teal pigment, what resins can be poured in such volumes without risking a poor quality and costing me so much? (Table is 70.5″x30″x1.5″, river of resin is approx 9″x70.5″x1.5″ [rounding up, if course]).
- May 9, 2019 at 12:57 pm #41879
Hi Andrew, I’m afraid I don’t have a list of resins that meet that requirement.
I suggest finding a resin you think will work, then checking with the manufacturer about the maximum amount that can be mixed and poured at once.

Good evening and thank you, in advance, for any asssistance.
I have a plastic mold that is 8cm x 11cm in the shape of a sneaker and its 2 1/2″ thick. The mold says its hold 2.07 oz of liquid.
I plan to use the casting as a photography prop. I intend to use my foredom drill to create notches to hold my jewelry piece as it us being photographed.
My research leads me to believe that a polyester resin is my best option.
I have a few questions:
1. Will the resin give me an issue in the silicone molding?
1a. I’ve read 3 oz at a time…that seems to cover my needs. Should I adhere to the 1/8 inch thick at a time…or does that just apply to flat surfaces?
2. I read that the surface dries sticky…what is my best option to create a clear glassy look using a foam applicator (I would rather not spray)
3. I read mixing slow and keeping a heat gun handy are my best defensed against bubbles w/o using a vacuum device. Any other suggestions?
4. Once I pour the resin in the mold, while its drying should I place a cover on top w/ some sort of ventaliation?
Any help would be greatly appreciated.

I will be making paperweights using a silicone baking mold of 6 dome shapes. Each individual dome is 2 3/4”dia and 1 1/3” deep. I intend to adhere a picture to the flat bottom.
1. Which product will work to create a clear outcome in a single pour?
2. After using ModPodge to seal the picture, do i use the same resin as a glue to affix the picture to the cured dome? Or do I use additional ModPodge?

How much resin do you want to mix and pour at once? That will help me with a recommendation. There is a resin volume calculator at this link: https://www.resinobsession.com/resin-calculator/
Yes, you can use the Mod Podge as a glue to glue the paper down to your sealed resin.

- January 25, 2020 at 11:01 am #83417
You need to check the maximum mixing amount for the resin you are using to see if you can pour that much at once. Otherwise, Pour a resin layer when the previous layer has started to cure and is sticky. That will minimize the lines between layers.

I would like to encase a root ball of a crepe myrtle I dug up. Making that the base of a table made out of the trunk/branches that would come out of the top of the cylinder of resin/roots. The cylinder would be about 20″in diameter by 5-6″ thick. Close to 1/3 to 1/2 the volume of the cylinder would be taken up by the tangle of roots. It would be for outside use (unless it comes out really good!), so I was wondering about tinting the resin a light smokey color since yellowing would happen eventually anyway. Do you have something that might work?
