A full 83-piece starter bundle that gets you pouring coasters the same day it arrives.

If you are new to resin, this kit removes every excuse not to start. It packs 18 oz of epoxy resin, 5 silicone molds, a silicone mat, gold foil paper, 12-color glitter, 12-color chunky glitter flakes, 18 dried flowers, measuring cups, wooden sticks, gloves, droppers, and tweezers — enough to make a whole set of coasters and then experiment with jewelry and art pieces. Owners consistently describe it as a complete, fun starter set with plenty of materials to learn on before you buy more supplies.

The quality here is genuinely impressive for the price point. The resin is crisp, cures hard with a shiny, transparent surface, and is formulated for low odor and few bubbles. People note it cures glossy and glass-like overnight, which is a fast turnaround for a beginner project. Since this set holds 18 oz versus the 16 oz in the LET’S RESIN kit below, you get roughly 12% more resin to play with — a small edge that matters when you are learning and making mistakes.

The recurring note in the reviews is that the resin and hardener bottles are a bit smaller than people expect, and the set is best for small projects. It is also worth knowing you will want a heat gun or torch to pop the stubborn bubbles that surface during pouring — it is not included, and one buyer specifically mentions wishing that was flagged on the box. Set up outside or in a ventilated space, and this kit will have you hooked.

A purpose-built coaster kit with molds sized right for most cups and a beautifully packaged unboxing.

This is the set that understands its job: it is built specifically for coasters, and it shows. The kit includes a 16 oz epoxy resin, coaster molds in different shapes, mixing cups, mica powder, golden flakes, and gloves — everything needed to pour a set of six coasters and then some. The molds are described as the perfect size for coasters or small trays, large enough for most cups, and the finished coasters come out extremely sturdy. The unboxing experience itself is a highlight, with owners calling the packaging excellent and everything arriving well-packed with nothing missing.

The resin itself is beginner-friendly with a simple 1:1 volume mix and an anti-foaming agent that helps the finished product come out bubble-free with high-gloss, crisp transparency like glass. People appreciate the easy-to-follow instructions and the fun mica powders for coloring. One owner noted that the coasters turned out great and the kit has lasted for several other projects beyond the original six, so there is real mileage in the bottle.

The caveat: the silicone molds are slightly warped, noticeable but not enough to ruin a project. It is the kind of imperfection that is fine for practice and personal gifts but not ideal if you plan to sell your coasters. This set is best treated as a low-pressure way to get a taste of resin crafting, not a professional production tool.

An American-made 64 oz coating with UV stabilizers that keep tabletops and coasters clear for years.

For surface-coating projects, this is a heavy hitter. Superclear is a self-leveling 1:1 epoxy that cures to a glass-like, high-gloss finish, and it is built with advanced UV stabilizers that help the cured surface resist yellowing over time — a critical feature for coasters that live on a sunny table. It is made in the USA by Fiberglass Coatings, LLC in Saint Petersburg, Florida, backed by over 60 years of resin manufacturing expertise, which gives it a credibility edge for buyers who care about sourcing. Once fully cured, the surface is food safe, so you can use these coasters confidently at a dinner party.

The reviews frequently praise the crisp results and the durability, with people noting it works great for redoing yellowed countertops and coating tree-trunk tables. Owners found that the instructions are clear and accurate, and the final result is a durable, smooth surface. The quality of the finish is the most-mentioned positive, followed by how well it functions for a variety of coating jobs — it is a dependable workhorse for anyone doing multiple projects.

The catch is that this resin is thicker than some alternatives, which means bubbles can be harder to remove if you are working in cooler temperatures. Buyers consistently recommend warming the surface to above 70°F before pouring, using a torch to pop bubbles, and pouring in thin coats. It takes effort to get a perfect result, but the pay-off is a professional, scratch-resistant finish that does not yellow.

A generous 45-minute working window and food-grade safety in a budget-friendly gallon size.

Time is the luxury here. INCLY gives you a full 45 minutes of working time at room temperature, which is a huge comfort zone for mixing in mica powder, arranging dried flowers, and carefully pouring your coasters at a relaxed pace. The kit comes with 0.5 gallon of crisp resin and 0.5 gallon of hardener, both meant to be mixed at a simple 1:1 ratio by volume. It is also food-grade, made with non-toxic materials, completely odorless, and non-flammable — a reassuring profile for your first resin project.

Owners are enthusiastic about the clarity and how easy it is to mix, with one experienced user calling it the best resin they have used in 60 years. People frequently praise how bubble-free it cures, noting that trapped air rises to the surface and escapes quickly, leaving a flawless, glossy finish. It self-levels and is described as “hard as a rock” once cured, and it resists heat up to 203°F, so your coasters stay beautiful under hot mugs. The 1-gallon size is ideal for multiple projects, and several owners mention repurchasing larger kits after a successful first batch.

The main note from a few owners is that the bottles are large, so handling the pour can be a little unwieldy for tiny projects — one person went back to a smaller version for easier handling. It is also on the softer side for very small cast pieces like hairsticks, though that is not a concern for flat coasters. For the price, you get a durable, clear, food-safe resin with a forgiving work time.

A generous 82 oz supply with pigments, glitter, and pump tops that make repeated pours easy.

If you plan to make coasters regularly, this kit is built to keep you stocked. It includes 41 oz of clear resin and 41 oz of clear hardener alongside pigments, mica powder, glitter, a pump head, measuring cup, silicone wand, spatula, gloves, stirring rod, tweezers, and a tablecloth — genuinely everything you need to start, with enough volume for many batches of coasters. The included pump tops are a standout feature that owners specifically love, since they make dispensing resin and hardener cleanly and accurately without messy bottle wrestling.

The resin itself is crisp, easy to mix with a 1:1 ratio, and has a self-defoaming, self-leveling function that keeps bubble trouble low. Owners note that the powders and inks have vibrant colors that blend well into the resin, and that the set is an amazing beginner bundle. The cured surface is glossy with a perfect texture, no yellowing, high-temperature resistance, and wear resistance — ideal for coasters that get handled daily. It dries in 8 hours and cures fully in 24 hours, which is on the faster end of the spectrum.

The mixed feedback centers on curing time and consistency — some owners find it dries crisp and fast, while others report slower curing or some bubble issues depending on their technique. You get about 30 minutes of comfortable working time before the resin starts to thicken, so it pays to have your design ready before you mix. It is an excellent value that owners recommend buying again.

A countertop-grade epoxy with a 64 oz supply and a long working time that pros appreciate.

This one is a performance pick for people who want a longer working time and a finish you can trust. Stone Coat has a 64-ounce supply (one-half gallon kit) that self-levels at a 1:1 mix ratio, and it is loaded with features: heat-resistant, scratch-resistant, UV-stable, and resistant to yellowing. The most praised aspect by a wide margin is the working time — owners love that they have ample time to work with the resin before it kicks. Its zero VOC formula means it lacks Volatile Organic Compounds, and it is USDA approved, which is a big deal for anyone who wants to avoid harsh chemical fumes in their craft space.

People describe the finish as beautiful and high-gloss, with owners successfully using it on bathroom countertops and outdoor concrete with no odor and easy mixing. One builder noted that as long as you watch the tutorials and prep properly, it “does what it says.” The UV stability and clarity are praised by a professional artist who passed it through outdoor durability tests with no yellowing. Because it self-levels and resists bubbles, it creates a flat, even surface ideal for coasters that need to sit flush on a table.

The trade-offs are real. The product is clearly positioned at the premium end, and some owners find it expensive for everyday hobby use. Durability gets mixed feedback — some find it incredibly durable while others note it can scratch more easily than expected. A few owners also say the self-leveling is not perfect, with bubbles reappearing despite using a heat gun, so patience and careful technique are required for a flawless pour.

A serious two-gallon kit that cures harder and faster, favored by wood turners and artists.

For anyone moving beyond basic coasters into thicker pours and larger projects, Beast Bond is the performance upgrade. This professional-grade kit includes a full 1 gallon of resin and 1 gallon of hardener, along with mixing sticks, a spatula, four measuring cups, five pairs of gloves, a silicone stirrer, pipette droppers, and a step-by-step manual. The formula gives you a 40-minute working time and cures in 24-48 hours, with a self-leveling, ultra-glossy finish that needs no polishing. It is ASTM D-4236 compliant, meaning it meets safety standards for art materials, and it is non-toxic, non-flammable, and free of VOC fumes.

The praise here is remarkably consistent — quality, curing performance, and bubble-free results are all called out. A wood turner reports that it turns beautifully on the lathe and costs a fraction of a big-name alternative, while a resin artist calls it “crisp with no yellowing or fog” and notes it handles flowers, glitter, and mica beautifully. People love that it dries to the touch much quicker than other brands, forms fewer bubbles, and results in a glass-like, scratch and moisture-resistant finish. It is the top choice for coasters that need to survive real life, from hot drinks to ring stains.

The main trade-off is the 2-gallon size. This is a 2-gallon kit, which is a lot of resin for a beginner making a single batch of coasters. It is an investment in a serious hobby, not a dabbler’s first kit. The 48-hour full cure also requires patience — owners note it is worth the wait for a hard, non-brittle surface that will not yellow.

The industry-leader in clarity with a slower cure that lets every bubble escape before it sets.

When clarity is the only thing that matters, Alumilite is the name pros reach for. This 1-gallon kit is industry-leading for clarity, with added UV resistance that slows down yellowing and keeps your coasters vibrant. The formula is easy to use with a simple 1:1 ratio by volume, and its slower cure is the secret weapon: it gives air bubbles more time to escape, resulting in a beautifully clear cast. Owners who make tumblers and molds swear by it, noting it produces no pooling or lumps and a hard, glossy finish.

The reviews highlight how well it accepts color — you can customize it with Alumilite dyes, alcoholic inks, or other non-water-based colorants, and it handles alcohol ink and mica beautifully. A creator who has run through 50 tumblers calls it the only brand they use after two other brands failed them. It is also praised for having no smell, being easy to pour into small crevices, and responding perfectly to a heat gun for bubble removal. For preserving trinkets or making personalized gifts, the ability to encapsulate items in crisp resin is a standout feature.

The premium price is the main hurdle, but owners say the superior clarity justifies it for keepsake pieces. The slower cure time (up to 72 hours for full hardness) doubles as both a feature and a patience requirement — you cannot rush it to the demold stage. There is also mixed feedback on reusability, with some owners noting leftover resin does not always go as far as expected.
