Do you know how to mix resin? Resin is a synthetic organic compound made up of a noncrystalline or viscous liquid substance. You can make several items from resin such as coasters, frames, keychains, hair accessories, and much more. In today’s post, I will teach you how to mix resin and hardeners. Mixing epoxy resin and hardener properly is essential for the epoxy to cure properly. Knowing the correct procedure for mixing resin will help you to get the best results. I’ve even included some tips for you in this article. You can keep on reading to learn how to mix resin.
How To Mix Resin?
Follow these steps to learn how to mix resin.
- In a suitable size container, pour resin to the mark on the container based on the mixing ratio of the product.
- Allow the resin to settle down.
- Now, add an equal amount of hardener.
- Using a stick, stir the mixture thoroughly for four minutes.
- Stop when there are no ribbons left in the mixture.
- After mixing resin and hardener, wait for about two minutes.
- Now, the resin mixture is ready for your projects.
If the mixing ratio is 1:1, take 1 ounce of resin and 1 ounce of hardener. You can use the same procedure if you want to learn how to mix resin and hardeners for fiberglass. Make sure you check if there is any unmixed product still in the container. Unmixed resin can cause soft spots or stickiness in your final product.
Mix Resin With Paddle Mixers
Paddle mixers reduce the amount of air that can be whipped into the resin. Helix Style paddle mixers are great for mixing larger volumes of epoxy resins. Simply pour equal amounts of resin and hardener into a paddle mixer. Make sure you mix slowly on the lowest speed setting on your drill.
Remember that if you whip a lot of air in, it will turn white, milky, or frothy. You can never recover that epoxy!
Mix Resin Without Bubbles
The most challenging part while mixing resin is bubbles! Many experts have trouble with bubbles. But do not worry, there are plenty of ways to deal with them. You can follow these steps to learn how to mix resin without bubbles.
- Before you start, place the resin and hardener bottles in a bucket of warm water.
- Let it sit for a while.
- Now, carefully pour resin down the side of the measuring cup.
- Then, add an equal amount of hardener in a similar way.
- Check if the resin and hardener are exactly in a 1:1 ratio.
- Using a stick, stir the mixture thoroughly for four minutes.
- After mixing resin and hardener, wait for about two minutes.
- Now, the resin mixture is ready for your projects.
During this method, avoid pouring from high above the cup as this can result in air bubbles. Also, mix smoothly, and consistently when mixing to avoid adding air bubbles.

Mix Resin Colors
Resin is widely used in school projects. In this tutorial, I’ll show you how to mix resin colors for your projects.
- First, mix up a batch of clear resin and hardener according to the package directions.
- Shake color bottles very well to get consistent color results.
- Start with the smallest amount of pigment and then add more in tiny increments.
- Mix the dye well to get the desired results.
You can use a white cup which will allow you to see the true colors more easily as you mix! 2 to 3 minutes are enough when it comes to how long to mix resin.
Factors To Consider
Now, I hope you’ve understood how to mix fiberglass resin. While mixing resin, you have to consider the following factors to get bubble-free resin.
- Resin can easily stick to a container. So, make sure you scrape the sides and bottom of the container while mixing.
- Ensure that the stir stick reaches the bottom of the container.
- You can use silicone and stainless steel stir sticks instead of wood as they are non-porous and reusable.
- Low-viscosity resins flow quickly and tend to be a bit easier to mix. However, high-viscosity resins move sluggishly and can trap air.
- Remember that 70F to 80F is the ideal working temperature for resin.

FAQ
What Is The Mixing Ratio For Resin?
2:1
To achieve the correct 2:1 mix ratio by volume, simply measure out 2-parts resin to 1 part hardener before mixing the components.
What Is A 1-1 Ratio For Resin?
A 1:1 ratio means 1 part of A resin and 1 part of B hardener are mixed together. These specific ratios mixed together create a very specific chemical reaction (a molecular handshake) which causes the combined epoxy cure solid. A hard epoxy cure is 100% dependent on properly measuring and mixing epoxy.
Should I Warm Up Resin Before Mixing?
Warming your resin/hardener in their enclosed bottles in a warm sink before mixing them together can help get rid of micro bubbles that can make your projects look cloudy.
Can You Over Mix Resin?
While it is extremely important to make sure that you stir your resin and hardener mixture for 3 minutes, you really can’t overstir epoxy resin. If you stirred for 10, 12 ,15 minutes, it’s not going to do any harm.
Do You Pour The Resin Or Hardener First?
Start by pouring 15 oz of resin into the measuring cup, followed by 15 oz of hardener, to give you 30 oz total. The 32 oz kit is the perfect amount for your project’s needs.

How Long Do You Let Resin Sit Before Pouring?
Layering in molds – allow each layer to set up for at least 3 hours before pouring next layer. Doming – you can apply your resin right after the 5 minute rest period, or let the resin thicken for up to 25-30 minutes.
What Is The Ratio Of Resin To Hardener?
Mix the resin
VOLUME – To achieve the correct 2:1 mix ratio by volume, simply measure out 2-parts resin to 1 part hardener before mixing the components.
Conclusion
In the above post, I’ve explained how to mix epoxy resin in detail. Working with resin is easy once you understand the elements of a successful pour! In a container, take equal amounts of resin & hardener and stir the mixture thoroughly for four minutes. Remember that resin and hardener have different densities. So, make sure you make accurate mixtures to ensure that the epoxy resin cures properly. Resin is a temperature-sensitive material so make sure you’re working in 70F to 80F temperatures. Once you learn how to mix resin, you can easily use resin in your DIY projects.
