Resin art, jewelry making, and DIY projects have surged in popularity in recent years. Incorrect ratios can lead to improperly cured resin, bubbles, or soft spots. Thankfully, a resin ratio calculator makes this process simple and precise, allowing you to achieve professional-quality results every time.
In this blog post, we’ll walk you through everything you need to know about resin ratios, how to use a resin ratio calculator, and why it matters to your projects.
What is Resin and Hardener?
Before we dive into ratios, let’s define what resin and hardener are.
Resin: A viscous substance that, when mixed with a hardener, will chemically react and cure into a solid. There are various types of resins, but epoxy resin is one of the most common in art and craft projects.
Hardener: The catalyst that helps the resin set and cure. Without the proper hardener, your resin won’t fully harden, leaving it sticky, gooey, or even uncured.
The Importance of the Correct Resin Ratio
In resin mixing, precision is key. Most resin brands come with a recommended ratio of resin to hardener, typically 1:1, 2:1, or 3:1. If the ratio isn’t followed precisely, the resin may not cure properly, leading to:
Soft resin: The resin may remain sticky or bendable.
Curing problems: The resin may take longer to cure or fail to cure altogether.
Bubbles: Incorrect ratios can lead to an increased chance of bubbles, disrupting the smooth finish.
Using the correct ratio ensures that the resin will properly harden and cure with a smooth, durable finish.
What is a Resin Ratio Calculator?
A resin ratio calculator is an online or downloadable tool designed to help you mix resin and hardener at the correct ratio. It does all the math for you, ensuring you get the precise amount of each component for your project. This is particularly useful if you’re working with large or small quantities, or if you need to adjust the ratio based on the container size you’re working with.
How Does a Resin Ratio Calculator Work?
Let’s walk through the process of using a resin ratio calculator.
1. Find Your Resin Ratio
The first step is to check the ratio specified by your resin manufacturer. As mentioned earlier, it can be 1:1, 2:1, or even more complex ratios. Make sure you understand the ratio properly before proceeding.
2. Input the Total Amount of Resin Needed
Most resin ratio calculators will ask you for the total amount of resin you need for your project. This could be in ounces, grams, milliliters, or another unit of measurement, depending on the calculator you’re using.
3. Select the Correct Ratio
Next, input the resin-to-hardener ratio (such as 1:1 or 2:1). The calculator will then automatically figure out how much resin and how much hardener you need for your project.
4. Get the Results
Once you enter the total amount of resin required and the ratio, the calculator will provide you with exact quantities of resin and hardener. For example, if you need 100 grams of total material and you’re working with a 1:1 ratio, the calculator will tell you that you need 50 grams of resin and 50 grams of hardener.
5. Mixing
Now that you have the precise measurements, you can confidently mix the resin and hardener together, following any specific instructions provided by the manufacturer.
Why Use a Resin Ratio Calculator?
Here are several reasons why using a resin ratio calculator is a great idea:
Accuracy
Mixing resin can be a bit tricky, especially when the quantities are small or large. A calculator eliminates the guesswork and ensures that you’re using the correct amounts for a successful outcome.
Save Time
The calculator does the math for you, so you don’t have to waste time calculating by hand or worrying about mistakes.
Prevent Waste
Using the right amounts means you won’t mix excess resin that could go to waste. It also prevents you from running short of resin mid-project.
Versatility
A resin ratio calculator is especially useful for different types of resin ratios, whether it’s a simple 1:1 ratio or a more complex ratio like 3:2. Some calculators even offer options for mixing in different measurement units like ounces, grams, or milliliters.
