ResinCrete, 3000G Water-Based Eco-Friendly Formula, 20-30 Minutes Demold Fast Curing Eco Casting for Beginners,Mineral Casting Powder, Easy Mix for DIY Home Art

This is an excellent product that dries rock hard really fast. The only thing that people need to know is that it's a little hard to color. I use alcohol inks and mica and it takes a lot to make it a different color than white. But once I got a hang of it, it turned out beautiful.

I've been using this for a while, a few different brands, so I think I can give an overall review on resincrete as well on this brand. This crete is smooth and finely powdered, no clumps. The 3 pack is a great price, and it cures up fast. Forget a 30-minute working time. You got 4-5 minutes max once you finish stirring for 3 minutes. And it takes 3 minutes, because figuring out the proper amount of crete to water is impossible basing it on the bag's recommendations on measurements. I've used marked cups, I've used my scale, and there is no good formula for crete to water like it says on the bag/s of product that I've used. You just have to start with an amount and keep adding water very minutely, and crete, usually a lot, until you get pancake batter. And don't be fooled by the amount of powder in your cup/bowl. It shrinks to 1/3 its size when you add water. So, it takes a ton of this stuff to make anything at all. I've used a 1000-gram bag and been able to make 3 trays, 2 lotus candle molds, and 2 medium sized trinket trays that have a candle cavity, (so a 2-cavity trinket box). Compared to a resin set, that's not a lot of stuff. But resin also releases toxic fumes and if you're doing a multicolored pour, you have to wait an hour or more between each pour, which is just annoying and takes up so much time. I do love resin though. For this stuff, you need to have your molds ready. Add in your flakes or stickers right away and press to the mold, because this stuff is thick, so additives get lost fast in the crete. Have your molds laid out. Have a spare or two small ones for any overage. Have extra mixing cups and a clean environment with no distractions. Because usually, no matter how much you calculate, you'll be mixing more crete, because you won't have mixed enough, and then you'll have a little extra. Stretched your hands, wrists, and fingers, because this needs to be mixed by hand, no mixer, because the powder is so fine. Don't lean over the cup or you'll snort the stuff, lol. It puffs when you add water. You're going to be mixing more than you're pouring, so be ready for that. The molds need to be filled pretty quickly to avoid harsh gradation of color and to make the layers bond together properly if you don't fill up the mold right away on the first pour. If you want to do multiple colors, you can do a little crete in each cup and add colorant to each, different. Then when you put the crete on the mold, little dabs or circles, it'll start curing fast. then you can add the second color right away, or do a full pour right away, and the original crete on the mold will stay right where it is. So, it's easy to do multicolored pours fast, but you need to be prepped for it! This stuff does dry hard and durable, but it'll shatter if you drop it on concrete. Ask me how I know. Or don't. You already know. It's not waterproof. You'll need to spray it with polycrylic to proof it. Or something like that. You can add resin on top of it. You can glue items to it fast and easy. I love that the cure time is around 30 minutes. For deeper pours, a few hours. But not 24 hours like straight resin. You can touch your molds and, if they feel hot, it's not time to demold yet. Colorant, colorant, colorant. Don't waste your time with adding in mica powder, alcohol inks, or acrylic paints. They won't add anything to the crete. You need airbrush paints. Super concentrated pigments. Which are expensive as heck, but they do add rich colors that pop. The others stuff is just wasteful. Even glitter won't pop in these without a proper colorant added. I love that I don't need my PPE to use this. I still wear gloves and my apron, but I don't have to use my mask. And my hot environment has these curing up fast. I love that I can do multiple colors in a single session in twenty minutes or so. I love the clean, smooth look of this stuff. It's classy looking. I love that I can finish this to make it shiny, or I can easily get a matte look. Most of all, I love the price on the 3000-gram set. It's really affordable for me needing to do a lot of crafts for an upcoming show. I like that these can be great crafts just from pouring the crete itself, or I can dress these up, paint them and seal them, add to them. This is a great craft medium, as long as you know what you're getting into. I'm having a lot of fun with this crete but dangit my hands are tired of mixing, lol. I'll be buying again. This brand is comparable to Let's Resin's brand, and others that I've tried. No better, no worse, but a way better price for a bulk buy.

Iam new to working with ecoresin and I have found it to be extremely easy to use once you understand the measuring guidlines. I used a scale to measure but also used silicone cups that had premeasured lines. I found that the scale provided a different consistency to when I using the premeasured cups. My initial pours went fairly well, no bubbles and even domes some well. Some didn't go as well because I over poured them and the mix began to harden. My second round was actually worse because I ubder poured the mould and when I attempted to go back and fill them, they poured horribly and began to harden before I could get you all the moulds. I tried to fix the overpowers but made them worse as seen in the pictures. So unfortunately, I will be needing some more practice and we'll be doing a lot of sanding on this second pour. Over all, I love the product and plan on finding more items to create with it.

I love this stuff. If youi have a smooth mold, it comes out like porcelain. If it's not a smooth mold, it comes out very smooth with a matte surface and is still beautiful. It is very durable and unless what you made has a thin part, (arms that stick out, a unicorn's horn or a gnomes tip of his hat), you can drop it and it rarely gets damaged. I've even dropped a couple of things on my concrete basement floor and they miraculously survived unscathed. Their customer service is first rate, which to me, is extrememly important. I wrote to them because a batch (2:5000gm bags) came through with a slight chemical smell to it. I wrote to them and they responded right away, more than once. They went to the 'formulation department' and asked if they had changed anything. When they told her yes, she got right back to me to let me know. I don't know for sure if they changed it back and I'm sure they didn't change it for me when I said I wouldn't be able to use it if it was going to have that smell, but this last 10k batch came without the smell. A bag seems expensive, but when you break it down to cost per ounce, it's very afforadable.

EcoResin, Jezmonite, PerfectCast, EcoCrete... The list of 10-powder-to-3-water-by-weight goes on and on. Distinguished from Plaster of Paris by the use of some binder unknown to me. but which substantially improves strength (though it's still prone to brittle fracture). There are 3 stages of curing for this stuff. First, after mixing it's a strongly thixotropic liquid. (hence, tapping and shaking molds are essential to getting bubbles out). For thin, flat castings, where it will tend not to flow to the edges of the mold, the shape isn't great for shaking and tapping, but if you gently hold a spatula or spoon against the surface and vibrate that hand, the whole mass will fluidize and self-level. After a fairly short time, it begins to set up, and at this time it starts to become warm (unclear if this is a hydration reaction, an exothermic polymerization reaction in the binder, or some of each). At the end of this phase, it will cool off, but it will still feel quite damp; it's still quite fragile. With the reaction over, and water evaporating from the casting, it becomes cool to the touch and damp during the final phase of the apparent cure. While it is possible to demold while it's still damp (and with some mold shapes you may have to because it could never hope to shed that water through the narrow neck), one must be very careful. Once it is fully dry, it has most of it's final strength, and it no longer needs special handling, you can paint it with acryllic paint, sand it, etc. You can also brush mica pigment on the inside of the mold and get a decent (not great) finish (in this case, plan to cover with at least clear acrylic, and be super careful while it's still wet, as the pigment can rub off easily. The work time is **short** - you mix that mica pigment with the powder ahead of time (and don't expect much out of mixed mica, it kinda sucks here), along with any other additives (fibrous strengtheners definitely work, though not as magically well as in epoxy). Heat resistance without catastrophic failure is incredible - though once heated beyond a certain temperature, it loses strength. This makes it suitable for ashtrays and candle holders, where epoxy would not be. Epoxy can be poured on top of this stuff and will stick decently (or excellently if you sprinkly this stuff with chopped glass or aramid fiber). There's just one big problems I have with EcoResin - and it really has nothing to do with the resin itself. This stuff is a RIPOFF. You don't even need to look off Amazon to find PerfectCast with the same FBA delivery. PerfectCast is to the best that I can tell identical (likely same for any plaster like thing with 10:3 ratio). For 20% less than this 1 kilo bag, you can get 4 lbs (1.8 kg) of perfect cast, with amazon shipping. So yeah, this is great stuff, but you can get it for less under other brand names. It has been claimed that it can be had for $8/4lb if you know where to go (but I don't). Either way, this price is at least twice as high as it could be.

Great product and value. Get ready to mix and pours like water. Releases bubbles easily and makes perfect casts with nice demold time. I've accidentally dropped a few pieces onto the floor with no chipping. My go to product for making painting figurines for the kids at my church.

I absolutely love it! It’s very easy to work with and results in a great final product. So long as you start with a clear open work area (because you will need to move things around as you go) follow directions, and work quickly, you will finish with a great item. Pros: *30 minute demold is legit. The only problem you might have is if there are tiny thin side details, they have a tendency to break off so leaving those in the mold longer would be best. *Bubbles are Not a problem. The mixture is thin, like water, so it really fills all those tiny details. *It stamps very well with ink. Can be sanded and painted as well. *It has a very different feel than resin. It’s very sturdy and substantial, more like a ceramic, and heavy. *Tiny little details and the spaces around lettering/numbers, no problem! Fills them all in with practically no bubble-gaps in the letters. (See pic for reference.) *Customer service is On Point! I also ordered the 10pk colorants made specifically for ResinCrete and one of the jars kept clogging and wasn’t usable. Within 24 hrs of contacting their customer service, there’s an entire replacement 10pk box in the mail. Cons: *Getting consistent color is nearly impossible from batch to batch. Make 3 batches, add same amount of color, get 3 somewhat different shades. *Hope you like Pastel. The base product is white and you are limited on how much colorant you can add before you risk curing issues, so everything will be a pastel shade. *If you do not mix the color in very thoroughly, the area of the product that touches the mold will cure darker than the rest. This could be an added bonus if that’s the look you are going for. *Don’t waste your time or money adding Mica to this product or to the molds before pouring it. The Mica dulls out completely when mixed in and putting it on the molds is useless because it just wipes off once demolded. *Getting the measurements down for how much you need to make to fill your molds is tricky and if you have to pour in different batches, there’s the risk of bubbles at the joining lines, not to mention the color matching issue previously stated. There’s no time to blend the lines when you pour the second batch because the first will have set a bit already. Overall, I’m completely thrilled with this product and the company.

This is a good quality product. Pours very smooth and very few bubbles. Great for beginners.
