Starting your first resin art project is genuinely exciting—the glossy finishes, the jewel-like colours, the way light plays through a cured piece. But before you even pick up a pigment or choose a mould, there is one fundamental question every beginner must answer: what is the correct resin mix ratio for beginners, and does it actually matter? The short answer is yes, it matters enormously. Getting your ratio wrong is the single most common reason new resin artists end up with sticky, soft, or cloudy results—and it is entirely avoidable once you understand what is happening at a chemical level.
In India, resin art has grown rapidly as a craft hobby, and the market is now full of products labelled 1:1 or 2:1 without much explanation of what those numbers mean in practice. Add to that our unique climate—high humidity in coastal cities like Mumbai and Chennai, extreme heat in Rajasthan and Delhi during summer, and cool dry winters in the north—and you have a situation where understanding your resin ratio is even more critical than it might be elsewhere. Temperature and humidity directly affect how resin cures, and a ratio that works perfectly on a cool October morning in Pune may behave very differently on a humid July afternoon in Kolkata.
This guide is written specifically for Indian beginners who want to understand the 1:1 vs 2:1 resin ratio explained in plain language, with practical examples drawn from real crafting situations. We will cover what these ratios mean chemically, how to measure them accurately, what goes wrong when you get it wrong, and how to choose the right product for your very first project. By the end, you will feel confident picking up your mixing cups and creating something beautiful.
What Is a Resin Mix Ratio and Why Does It Matter?
Every epoxy resin product consists of two separate components: Part A (the resin) and Part B (the hardener). These two liquids are chemically inert on their own—they will not cure, harden, or do anything useful unless they are combined in a very specific proportion. That proportion is what we call the resin mix ratio for beginners to understand first.
The ratio tells you how much of Part A to combine with how much of Part B. A 1:1 ratio means equal parts resin and hardener—100 grams of resin mixed with 100 grams of hardener, for example. A 2:1 ratio means two parts resin to one part hardener—200 grams of resin mixed with 100 grams of hardener.
Why can't you just eyeball it? Because the curing reaction—called polymerisation—is a precise chemical process. The resin molecules need exactly the right number of hardener molecules to bond with. Too much hardener and you get excess unreacted material sitting in your cured piece, causing softness and tackiness. Too little hardener and the resin never fully crosslinks, leaving you with a permanently flexible or sticky surface. This is why how to mix resin correctly is not just advice—it is chemistry.
The Chemistry Behind Resin Curing (Simply Explained)
You do not need a chemistry degree to understand this, but a little background helps you make better decisions. Epoxy resin (Part A) contains molecules called epoxide groups. The hardener (Part B) contains amine groups. When you mix them, these groups react together in a chain reaction, forming long polymer chains that cross-link into a rigid, glass-like solid.
The ratio is determined by the equivalent weight of the specific resin and hardener formulation the manufacturer uses. A 2:1 product uses a more concentrated hardener—meaning a smaller volume of it contains enough amine groups to react with a larger volume of resin. A 1:1 product uses a less concentrated hardener that needs equal volume to achieve the same reaction. Neither is inherently better; they are just different formulations designed for different application needs.
What this means practically: you cannot swap hardeners between products. If you have a 2:1 resin and accidentally use a 1:1 hardener at equal volumes, you will have way too much hardener, and the result will be sticky and soft. Always use the resin and hardener that come together as a set.
Understanding the 1:1 Resin Ratio
What It Is
A 1:1 ratio means you mix equal parts by volume (or sometimes by weight, depending on the product—always check the label). So if you need 200ml of mixed resin, you pour 100ml of Part A and 100ml of Part B.
Who Uses 1:1 Resin?
1:1 resins are very popular for coating applications—tabletops, paintings, and artwork where you pour a thin, even layer over a surface. They tend to have a longer working time (also called pot life), which means you have more time to work with the resin before it starts to thicken and cure. This makes them forgiving for beginners who are still learning to work quickly.
Pros of 1:1 Ratio
- Easy to measure—equal parts is intuitive and hard to miscalculate
- Longer pot life in many formulations, giving you more working time
- Popular for art resin and coating applications
- Widely available in the Indian market
Cons of 1:1 Ratio
- You use more hardener per batch, which can be more expensive per pour
- Some 1:1 formulations are less suitable for deep pours (they can generate excessive heat)
- May have a shorter shelf life once opened
Understanding the 2:1 Resin Ratio
What It Is
A 2:1 ratio means two parts resin to one part hardener, measured by volume or weight as specified. If you need 300ml of mixed resin, you use 200ml of Part A and 100ml of Part B. This is the epoxy resin hardener ratio used in many professional and craft-grade products available in India, including the popular range stocked at Shrebhavi.
Who Uses 2:1 Resin?
2:1 ratios are extremely common in craft and art resin products designed for moulds, jewellery, coasters, trays, and decorative items. They are also widely used in deep-pour applications because the chemistry often allows for slower, more controlled heat release during curing. Many beginners in India find 2:1 products easier to work with for mould-based projects because the smaller hardener volume makes the overall cost per project slightly lower.
If you are looking for a best resin kit for beginners in India, a 2:1 formulation in a smaller pack size is often the most practical starting point. The Resin 2:1 (150gm) from Shrebhavi is an excellent entry point—small enough to practise without wasting material, but enough to complete a few coaster or jewellery projects.
Pros of 2:1 Ratio
- Economical—less hardener used per batch means the hardener component lasts longer
- Versatile across mould-based and coating projects
- Often formulated for good clarity and low yellowing
- Widely available as resin art supplies for beginners India online
- Easier to scale up for larger projects
Cons of 2:1 Ratio
- Slightly more calculation needed when measuring—easy to get wrong if you measure by eye
- Some beginners accidentally mix 1:1 out of habit, causing curing failures
- Pot life can be shorter in some formulations, requiring faster working

How to Mix Resin Correctly: Step-by-Step
Understanding the ratio is only half the battle. How to mix resin correctly involves precise measurement, proper mixing technique, and attention to timing. Here is a practical step-by-step process for a 2:1 resin mix, which applies to products like the Resin 2:1 (300gm) from Shrebhavi.
What You Will Need
- Digital kitchen scale (accurate to 1 gram—do not use measuring cups for resin)
- Two disposable mixing cups (graduated cups are helpful)
- Silicone spatula or wooden stir stick
- Nitrile gloves (not latex)
- Safety goggles
- Well-ventilated workspace
Step 1: Calculate Your Quantities
Decide how much total mixed resin you need. For a 2:1 ratio, divide your total by 3 to get the hardener amount, and multiply that by 2 for the resin amount. For example, if you need 150g total: hardener = 50g, resin = 100g.
Step 2: Measure Part A (Resin)
Place your mixing cup on the scale, tare to zero, and pour in the resin component until you reach your target weight. Do this slowly—resin is viscous and easy to overpour.
Step 3: Measure Part B (Hardener)
In a separate cup, measure the hardener accurately. Then pour it into the resin cup. Never add resin to hardener—always hardener into resin.
Step 4: Mix Slowly and Thoroughly
Stir for a full 3–5 minutes using a slow, deliberate motion—scraping the sides and bottom of the cup. Fast, vigorous stirring introduces air bubbles. The goal is thorough mixing, not speed. The mixture should look completely uniform with no streaks.
Step 5: Scrape and Transfer
Pour your mixed resin into a second clean cup and stir for another 1–2 minutes. This "second mix" technique ensures any unmixed resin stuck to the sides of the first cup does not end up in your project.
Step 6: Work Within Your Pot Life
Once mixed, you have a limited working window before the resin starts to thicken. In Indian summer conditions, this window can be shorter than the manufacturer's stated time because heat accelerates the reaction. Work efficiently.
Mixing Resin in Indian Climate Conditions
This is a section you will not find in most international resin guides, but it is absolutely critical for anyone working on a resin project for beginners in India. Our climate creates specific challenges that affect both the mixing process and the final cure.
Heat and High Temperatures
In cities like Delhi, Jaipur, and Nagpur, summer temperatures regularly exceed 40°C. Heat accelerates the curing reaction, which means your pot life shrinks dramatically. A resin that gives you 30 minutes of working time at 25°C might give you only 15–18 minutes at 38°C. Additionally, in very hot conditions, large pours can generate excessive heat (called an exothermic reaction), which can crack or yellow your piece.
Tip: In summer, work in the early morning when temperatures are lowest. Store your resin and hardener in a cool, shaded area before mixing. Never refrigerate resin, but keeping it away from direct sunlight helps.
Humidity and Moisture
High humidity—common in Mumbai, Kochi, Chennai, and during monsoon season across India—is another major factor. Moisture can interfere with the curing process, causing surface cloudiness, fish-eye effects, or a permanently tacky finish. This is one of the most common reasons for cloudy resin for beginners in India.
Tip: Work indoors with a dehumidifier or air conditioner running if possible. Avoid mixing resin on rainy days unless your workspace is well sealed. Make sure your moulds and surfaces are completely dry before pouring.
Winter Conditions
In northern India during winter, temperatures can drop to 10–15°C in cities like Delhi, Chandigarh, and Shimla. Cold temperatures slow the curing reaction and make resin much more viscous, which makes it harder to mix and pour without trapping bubbles. Cold resin also takes significantly longer to cure—sometimes 48–72 hours instead of the standard 24 hours.
Tip: Warm your resin and hardener bottles in a bowl of warm water (not hot—around 30–35°C) for 10–15 minutes before mixing. This brings them to a workable viscosity without compromising the chemistry.
Common Mistakes Beginners Make with Resin Ratios
Understanding the theory is one thing; knowing what can go wrong in practice helps you avoid the most frustrating beginner experiences. Here are the mistakes we see most often:
Measuring by Eye or Using Spoons
This is the number one mistake. Resin chemistry is precise. A 10% error in your ratio can mean the difference between a perfectly cured piece and a sticky mess. Always use a digital scale.
Confusing Volume and Weight
Some products specify ratios by volume, others by weight. Resin and hardener have different densities, so 100ml of resin does not weigh the same as 100ml of hardener. Always read the product instructions and follow the specified measurement method. Most quality products like those from Shrebhavi specify clearly—check the label before you start.
Not Mixing Long Enough
Under-mixing is almost as bad as wrong ratios. If you stir for only 60 seconds, you will have unmixed pockets of resin or hardener in your mixture. These create soft spots, sticky patches, and uneven curing in the finished piece. Three to five minutes of steady mixing is the minimum.
Using Old or Incorrectly Stored Resin
Resin and hardener have a shelf life, typically 12–18 months from manufacture. Hardener in particular can absorb moisture from the air and turn cloudy or amber-coloured. Once this happens, it may not cure properly regardless of how accurately you measure. Store both components tightly sealed, away from heat and humidity.
Thinking "A Little Extra Hardener" Will Speed Up Curing
This is a very common misconception. Adding more hardener than specified does not make resin cure faster—it creates an off-ratio mixture with excess unreacted hardener, resulting in a soft, flexible, or sticky cure. If you want faster curing, increase the ambient temperature slightly instead.
Why Is My Resin Sticky After Curing?
This is one of the most searched questions among Indian beginners: why is my resin sticky after curing? The answer is almost always one of these: incorrect ratio, insufficient mixing, high humidity during cure, or resin that is past its shelf life. Go through this checklist before assuming the product is faulty.
Safety Notes Every Resin Beginner Must Read
Resin art is a safe and enjoyable hobby when you follow basic precautions. Please do not skip this section—it is short but genuinely important.
- Always wear nitrile gloves. Uncured epoxy resin and hardener can cause skin sensitisation with repeated exposure. Once sensitised, you may develop allergic reactions. Nitrile gloves (not latex, which can degrade) protect your hands effectively.
- Work in a well-ventilated space. Epoxy hardeners emit fumes that can cause respiratory irritation. Open windows, use a fan to direct fumes away from you, or work outdoors in a covered area. Avoid enclosed rooms without airflow.
- Wear safety goggles when pouring to protect your eyes from splashes.
- Keep resin away from children and pets until fully cured. Fully cured epoxy is generally considered safe, but uncured resin is a chemical irritant.
- Do not pour liquid resin down the drain. Let any waste resin cure completely in a disposable cup, then throw it in the bin as solid waste.
- Be aware of the exothermic reaction. Large batches of resin generate heat as they cure. If you notice your mixing cup getting very hot, pour the resin immediately into a thin layer to dissipate the heat. Never leave a large batch of mixed resin sitting in a cup—it can crack the cup or even cause a fire in extreme cases.
- UV resin safety: If you are using UV resin, the UV lamp used to cure it emits UV-A radiation. Do not look directly at the lamp and avoid prolonged skin exposure during curing.
Choosing the Right Resin Kit for Your First Project
Now that you understand the ratios and the process, let us talk about choosing your first product. As a beginner, the most important factors are: pack size (start small), clarity of instructions, and availability of support if something goes wrong.
Start Small
Do not buy a large kit for your very first project. You will almost certainly make some mistakes—wrong pour timing, a bubble you could not remove, an uneven surface—and that is completely normal. Starting with a smaller pack means those learning experiences cost less. The Resin 2:1 (150gm) is ideal for a first attempt at jewellery or small coasters, while the Resin 2:1 (300gm) gives you enough material for a few practice pours and a finished piece.
Choosing a 2:1 Kit for Mould Projects
If your first project involves silicone moulds—coasters, jewellery pendants, decorative trays—a 2:1 ratio epoxy is your best bet. The Resin 2:1 (1.5kg) is a great option once you are past the beginner stage and ready to produce multiple pieces or larger items. For those who want to stock up and save, the Resin 2:1 (1.5kg+300gm) Set/Combo offers excellent value and ensures you have enough material for an extended creative session without running short mid-project.
What to Look for in a Beginner Resin Kit
- Clear ratio instructions on the label (by weight or volume—specified)
- Low viscosity for easy pouring and bubble release
- Good clarity and low yellowing formulation
- Reasonable pot life (20–30 minutes minimum for beginners)
- Trusted supplier with consistent product quality
Shrebhavi stocks a carefully curated range of resin art materials India crafters can rely on, with consistent quality across batches—something that matters more than most beginners realise. Inconsistent resin quality is a real problem with some unbranded products, where the ratio specifications may not match the actual chemistry of the product.
How to Mix 2:1 Epoxy Resin for Your First Project: A Quick Recap
Here is the practical summary for how to mix 2:1 epoxy resin for first project success:
- Gather your materials: scale, cups, spatula, gloves, goggles
- Calculate: total needed ÷ 3 = hardener; total needed × 2/3 = resin
- Measure resin (Part A) first, then hardener (Part B) separately
- Pour hardener into resin
- Mix for 3–5 minutes, slow and thorough, scraping sides and bottom
- Transfer to a second cup and mix for 1–2 minutes more
- Add pigments or inclusions if desired
- Pour within your pot life window
- Use a heat gun or torch briefly to pop surface bubbles
- Cover and allow to cure undisturbed for 24–48 hours
Frequently Asked Questions
What happens if I use the wrong resin ratio?
Using the wrong ratio—either too much or too little hardener—means the chemical reaction cannot complete properly. The result is typically a sticky, soft, or flexible cure that will not harden further. In some cases, the surface may feel dry but the interior remains uncured. Unfortunately, there is no fix once resin has cured incorrectly; you will need to start the project again. This is why accurate measurement is non-negotiable.
Can I mix 1:1 and 2:1 resins together?
No, absolutely not. Each resin system is formulated as a matched pair—the resin and hardener are designed to react with each other at a specific ratio. Mixing components from different systems, or using a 1:1 hardener at 2:1 proportions, will result in a failed cure. Always use the resin and hardener that come as a set from the same product line.
Why is my resin sticky after curing even though I followed the ratio?
Sticky resin after curing—despite correct ratios—is usually caused by one of three things: insufficient mixing (under-stirring leaves pockets of unmixed components), high humidity in the workspace during curing, or resin that is past its shelf life. Check that your hardener has not turned cloudy or amber, ensure you are mixing for at least 3–5 minutes, and try curing in a less humid environment. In India, monsoon season is particularly challenging for resin work.
Should I measure resin by weight or by volume?
Always follow the specific product's instructions—some specify by volume, others by weight. For most craft epoxy resins, measuring by weight on a digital scale is more accurate and recommended, because resin and hardener have slightly different densities. A digital scale accurate to 1 gram is an essential tool for any resin artist and is inexpensive to purchase online.
Which is better for a beginner: 1:1 or 2:1 resin?
Both can work well for beginners, but for mould-based projects (coasters, jewellery, trays), a 2:1 ratio is generally more economical and widely available in India. The measuring is slightly more involved, but with a digital scale it is straightforward. For coating projects—sealing artwork or creating a glossy tabletop—1:1 can be more intuitive because of the equal-parts measuring. Starting with a small 2:1 kit for your first mould project is a popular and practical choice among Indian craft beginners.
How do I avoid cloudy resin in humid Indian conditions?
To avoid cloudy resin, work in an air-conditioned or dehumidified space, especially during monsoon season. Ensure all moulds and surfaces are bone dry before pouring. Avoid breathing over your resin while it cures (moisture from breath can cause cloudiness). Use a heat gun or torch briefly over the surface after pouring—this helps pop bubbles and can reduce surface cloudiness. If you are in a very humid city, consider working in the early morning before humidity peaks.
How long does 2:1 epoxy resin take to cure in Indian summer heat?
In Indian summer conditions (35–42°C), 2:1 epoxy resin typically reaches a demould-ready cure in 12–18 hours rather than the standard 24 hours. However, full hardness and chemical resistance may take 48–72 hours even in heat. The trade-off is that your pot life is also shorter in heat—sometimes as little as 15–20 minutes. Work efficiently, and avoid doing large, deep pours in peak summer heat as the exothermic reaction can be intense.
Wrapping Up
Choosing the right resin mix ratio for beginners is the foundation of every successful resin project. Whether you are working with a 1:1 or 2:1 formulation, the principles are the same: measure accurately, mix thoroughly, respect your pot life, and account for India's unique climate conditions. The difference between a beautifully cured piece and a sticky disappointment almost always comes down to these fundamentals.
For most Indian beginners starting with mould-based projects, a 2:1 epoxy resin is an excellent choice. Starting small with the Resin 2:1 (150gm) lets you learn the process without significant material waste, and stepping up to the Resin 2:1 (1.5kg+300gm) Set/Combo makes sense once you are confident and ready to produce more pieces. Shrebhavi's range of resin art materials is specifically stocked to support Indian crafters at every stage, from first pour to professional production.
Take your time, invest in a good digital scale, work in a ventilated space, and do not be discouraged if your first project is not perfect. Every experienced resin artist has a story about their first sticky, cloudy, or cracked piece—it is part of the learning curve. With the right knowledge and the right materials, your second project will be noticeably better, and by your fifth or sixth, you will wonder what all the fuss was about. Happy pouring!
