How do you mix and apply epoxy?

What is epoxy? Epoxy is a material that has many uses, including as a coating and adhesive. Epoxy can seal, coat, and waterproof materials like wood, concrete, plastic, and metal.

It can also be used to repair cracks in damaged wood. To use epoxy correctly you need to learn how to mix it correctly so it cures properly and doesn’t yellow over time or end up tacky.

Epoxy is a wonderful material that has a wide variety of uses for the home. It’s not difficult to use if you know what you are doing but unlike paint or other finishes, it does require mixing at the point of application which makes it more involved than simply opening a can of paint and getting started.

How do you mix and apply epoxy?

To mix and apply epoxy, you need to wear gloves, prepare your area and make sure you have the proper supplies.

Make sure to use a respirator when working with rubbing alcohol, and avoid breathing fumes from epoxy.

To mix the epoxy:

  • Mix the two parts in equal amounts. The resin and hardener must be mixed in equal amounts by volume. For example, if you pour half an ounce of resin into your mixing cup, pour half an ounce of hardener into your mixing cup as well. You can use digital kitchen scales to accurately measure each component or an inexpensive plastic measuring cup designed for liquids (you will use these measuring cups only for epoxies).
  • Measure only what you will use in 15 minutes. Only mix enough for what you need for about 15 minutes at a time. Epoxy has a shelf life of about seven days once it is mixed together; after that, it begins breaking down due to normal chemical reactions within the mixture itself.
  • Thoroughly mix the resin and hardener before adding any colorants or fillers. Stir slowly with a stir stick until all color streaks are gone from a mixture (about 30 seconds). When color is uniform throughout continue stirring slowly for another 45 seconds to 1 minute ensuring no air bubbles are trapped along sides or bottom of container (use toothpick or another pointed object to release bubbles along sidewalls & bottom of measuring cup/container).

How do you mix epoxy resin for beginners?

> To do this, simply add the hardener to the resin and mix it together until it is an even consistency.

> Make sure you are in a well-ventilated area when doing this, as you never want to be mixing epoxy resin in a confined space.

> Mixing epoxy resin together is simple enough, but to make sure that you have mixed the resin and hardener thoroughly and evenly, it is important to use an appropriate tool for the job.

> While some people may choose to use their hands for mixing resin together, this isn’t always recommended because of potential damage done by harsh chemicals.

> It’s also more difficult than using a wooden stick or brush specifically designed for mixing epoxy resins.

What is the best way to mix epoxy?

Mixing epoxy is not a difficult process. If you follow these steps you should be able to easily mix and apply epoxy to your project.

  • Measure out the right amounts of resin and hardener with a scale. It’s extremely important to get the ratio right, or your epoxy could take longer to cure than it should or even not cure at all!
  • Combine the resin and hardener in a clean mixing container on a flat surface. Make sure that your container is large enough for you to work with, has smooth sides for easy cleanup and can be tossed away when finished if need be (some epoxies will bond with plastic containers).
  • Mix for the recommended amount of time using a clean mixing stick for each part of the project (if you mix several batches of epoxy at one time, make sure that you do them separately). Use only as much energy as needed without creating too much air in your mixture
  • Use a bubble popper tool to release any bubbles from your mixture before applying it over wood or other porous material and let it sit while they rise up through the surface of the epoxy; this is referred to as “degassing” and helps ensure proper curing process over porous materials such as wood chips that may harbor trapped gases inside their cells which cannot escape during curing stage otherwise causing defects within cured finish layer once applied where these gases reside during curing cycle (not just on top but also diffusion into finish layer).
  • Degas again once every hour if necessary until no more bubbles come up after degassing process has been completed; wait 24 hours before proceeding to next step below so there won’t be any leftover gas bubbles inside surface layers yet still forming between inner cell structures within wood surfaces over time which can cause defects within cured finish later down road when exposed under high humidity environments near water leaks or other moisture sources near future years after application has been completed long ago now gone by…

What is the ratio of epoxy and hardener?

The ratio of epoxy to hardener is almost always 2:1. The only time you might use a different ratio is if it’s a slow curing epoxy, in which case the ratio would be 1:1.

It’s also important to know that slow curing epoxies are more expensive than fast curing ones, so if you have the option, go for the faster cure.

What is the ratio for mixing epoxy?

Epoxy can be a great tool for repairing furniture and other household items. However, mixing it correctly is important to ensure that the epoxy doesn’t cure too quickly or slowly.

The ratio of epoxy resin to hardener is 1:1, or two equal parts. After measuring out the appropriate amount of each material, mix them thoroughly in a well-ventilated area with an application tool or stir stick for at least three minutes.

It’s also possible to add colorants and other additives into pre-mixed epoxies. If you want your surface to dry clear and glossy, choose a resin that’s advertised as such before beginning your project.

How do you mix epoxy resin without bubbles?

The number one reason for bubbles in epoxy resin is mixing too fast. While you may be eager to get started, it’s important to mix slowly so that air does not become trapped in your resin.

This can happen if you mix on a slope, so make sure you use a flat surface. If the bubbles persist, try mixing in smaller batches next time.

Where do you mix epoxy resin?

You’re going to want all the space you can get to pour and mix the resin. Be sure you have a large, flat surface area that you can use for mixing. Ideally, you’ll have a surface made of fiberglass or another material that is both heat resistant and disposable.

If it’s not possible to have both, choose the disposable option first. You will also need a mixing bowl at least twice as large as the amount of epoxy you plan on mixing together.

What should resin look like when mixed?

You are now ready to mix your epoxy. Pour the resin and hardener together, and mix them thoroughly with a wooden dowel or stir stick for at least two minutes.

Be sure to scrape the sides of your mixing container to ensure that you combine all traces of undissolved hardener.

  • What should resin look like when mixed?

Your fully mixed epoxy should be even in color and consistency; free of bubbles, lumps, streaks, and impurities; and have a smooth, even consistency.


Mixing and applying epoxy is crucial to the final result of your project. Fortunately, it’s not hard to do once you know the basics.

As long as you follow the instructions and make sure your materials are clean, safe, and prepared properly, you can’t go wrong!
