Best Epoxy Glue – Where and How to Use Epoxy Adhesives

In modern manufacturing and materials science, more and more research is done on developing materials and substances that can make our lives easier. One area of innovation with a surprisingly significantly impact on our lives involves adhesives. New types of glues with increasingly effective adhesive qualities have removed many limitations in the world of woodwork, manufacturing, and engineering. One of the most impressive of this new generation of adhesives is epoxy glue. But, you may wonder, what are epoxy glues? This article will look at what these glues do, how they can be utilized, and how they work.



What Is Epoxy Glue?

When one thinks of glue we normally think of a white, sticky material that is available from your local convenience store. However, if you are dealing with crafting and DIY, you will quickly realize that specialist adhesives exists for nearly every type of material and applications.

Materials commonly used in manufacturing and crafting range from highly porous to completely smooth with no porosity at all.

Adhesives that work very well on one type of surface may be completely useless on another. In addition, bonded materials needs to withstand a variety of extreme forces and environmental conditions that can degrade some types of adhesives far quicker than others.

Two-Part Epoxy Syringe

What is so great about epoxy glues is that these have been specifically formulated to adhere to multiple surfaces an withstand many other extreme conditions. Once the preserve of heavy industry, commercial epoxy adhesives are now readily available both in-store and online and are well priced. You also do not need a degree in chemical engineering to use epoxy glues, they are simple to mix and apply, and they do an amazing job, particularly the types that have been designed for a specific application.

You can purchase epoxy glues in two forms: either single-part glue or two-part epoxy glue.

Mixing Two-Part Epoxy Adhesive

How do the two types of epoxy glue differ? Any epoxy consists of a resin and a hardener. When these are combined a chemical reaction is triggered that causes the resin to cure to a rock-solid substance that binds on a molecular level to any surface it has been applied to. When you buy two-part epoxy, you are in charge of activating the curing process.

Most epoxy glues will come in two separate containers and you will have to mix these in a specific ratio that will be clearly indicated on the packaging.

When you buy one-part epoxy, the resin and the hardener have already been combined by the manufacturer and is already curing (albeit very slowly). When you apply a one-part epoxy to a surface, that curing process is then rapidly advanced by an environmental factor, like exposure to a specialist UV light or air.

One-Part Epoxy on Metal

You will have to ensure that you are wearing safety gear when working with epoxy glue, as some adhesives can be particularly challenging to remove from your fingers, hands, and any other appendage. In addition, the hardeners in epoxy can contain dangerous chemicals that can lead to severe discomfort if they come into contact with your respiratory system, eyes, or skin. This can seem a little scary, but remember that these glues are only dangerous while they are wet. When epoxy adhesive has completely cured it is both durable and 100% food safe!


What Can Epoxy Adhesives Be Used On?

As far as multi-purpose adhesives go, epoxy is one of the most versatile around and can be used in almost any industry. What follows is a look at a few different surface types, and how epoxy adhesive performs when applied to them.



If you find yourself in a situation where screws, nails, and conventional wood glues are just not enough to keep your wooden workpieces together, you can simply turn to epoxy adhesive. The two-part epoxy adhesive bonds to wooden surfaces very well. In addition, epoxy adhesives can withstand forces that are normally only managed by welded metal, and shows amazing tensile strength.

Use Epoxy Glue on Wood

You will be glad to know that two-part epoxy adhesives are readily available and extremely well priced, although if you are faced with a bigger workpiece, you may be frustrated by the quantities they are available in.



You may have found yourself in the situation where you need to hang some furnishings or your photographs, and you do not want to have to haul out the masonry drill and screws and create dust everywhere. Luckily there is an alternative option, you can use some epoxy glue that has been specifically graded for hard porous substances like plaster, mortar, and brick.

Epoxy Putty for Masonry

There are adhesives available that are sufficiently strong enough to offer support to large photo frames, and in some instances even entire shelving units if you are looking to test the limitations of the adhesive’s effectiveness.

While epoxy adhesives perform well when they adhere to materials such as mortar and/or brick, we do not recommend that you substitute them as building materials, and neither would the manufacturers.



The human race has been looking for effective ways to join metal together, for as long as we have known how to refine and mold it. This is another substance that can be effectively bonded using the correct epoxy resin. Epoxy resin offers a durable and well-priced option for your adhesive requirements. Epoxy adhesives can be graded to be utilized inside internal combustion engines and high-pressure water pumps, which should give you a good idea of their effectiveness.

Epoxy Glue is Waterproof

The search for stronger and more durable epoxy resins is never-ending, even though the majority of standard adhesive grades for metal are already able to withstand temperatures well past the boiling point for more than 10,000 hours.



We have all been in the, unfortunately, situation where one of our favorite coffee mugs or a cherished piece of chinaware is tragically broken. The next time you find yourself in such a situation we recommend reaching for some epoxy glue!

As previously mentioned, epoxy resin is not only a fabulous adhesive, but it is also 100% food-safe once it has had the opportunity to cure completely. This means that it is ideal to use to repair items that will come into contact with foodstuff.

Epoxy Adhesive for Repairs

It can prove challenging to repair ceramics using epoxy glue as a result of the inherent slippery surface, but will a little bit of preparation and some patience, you can repair any ceramic object, even your favorite coffee mug!


What Are the Pros and Cons of Epoxy Resin Glue?

While epoxy resin is considered to be one of the most effective methods to stick things together, there are naturally some advantages and disadvantages to the material. We have put together some further details in terms of the pros and cons of epoxy resin glue to give you a better understanding of epoxy resin glue as a whole.


Pros of Epoxy Resin Glue

Let’s begin with the good news, epoxy resin glue is one of the most versatile materials available on the planet. One of the main characteristics of epoxy glue is its shear strength and tensile strength. That being said, industrial-strength epoxy takes these attributes to an entirely different level. These adhesives are also extremely resilient to extreme cold and heat, making epoxy the go-to solution for projects that require high adhesion and durability.

Epoxy is Ideal for Extreme Conditions

As well as being strong, epoxy glue is also extremely flexible and if needed, even pliable. You could create an epoxy resin for practically any application should you have sufficient resources and time. Unfortunately, in certain circumstances using an epoxy is not the most cost-effective option, especially where an existing bonding solution is in widespread use.

Epoxy glue will stick to practically anything, the exception only being certain types of plastics or anything that potentially could have a bad reaction to the substance inherent in the chemical composition. Another reason that makes epoxy resin glue so popular, is thanks to it is 100% food safe once it has completely cured.

Cons of Epoxy Resin Glue

As previously mentioned, epoxy resin glue is one most versatile materials around. That being said, it is by no means a universal tool. One of the handfuls of cons is that epoxy resin glue will take a significant amount of time to prepare and cure. It should also be mentioned that the production of epoxy resin glues and other similar products is not good for the environment.

Epoxy Has a Long Cure Time

We have mentioned that epoxy resin is food safe once it has been completely cured, but while it is in its two-part form, the hardener and the resin can be toxic and will result in discomfort if ingested or inhaled. You will have to procure and wear the necessary personal protective gear when working with the two substances, including eye protection, a face mask, and of course, gloves that have been graded for use with hardener and resin.

Epoxy Requires Safety Gear

Once your epoxy resin has cured completely, it is chemically inert and safe, but you should still take care when working with it. For example, should you have to sand, drill or make any changes to a cured epoxy that could result in dust, keep in mind that epoxy dust can obstruct or irritate your airways.

How to Use Epoxy Glue

It may seem daunting to work with epoxy glue, but it is relatively simple to do and can be quite fun, and is an easy way to handle unforeseen mishaps life has thrown your way. What follows is a look at how to use epoxy glue effectively so you achieve amazing results.


Prepare Your Workspace

Before you begin, you want to ensure that you do not get your workspace, or yourself dirty at all, when working with epoxy glue. Once you have put on all your necessary protective gear, you will need to protect your workspace by ensuring you have sufficient ventilation, and that you have covered up anything that you do not wish to get any resin on, using some old newspaper, or a tarp.

If you tend to be a bit sloppy, maybe apply some painter’s tape to those areas of the object where you do not want any glue to spread.

Ventilate Area Where Using Epoxy


Prepare Your Workpiece

Epoxy will only perform as intended by the manufacturer and yourself if you have prepared your workpiece properly. To prepare your workpiece, keep in mind that different materials have different preparation methods. The common element with all of them is that you have cleared any dust, dirt, grime, and any other foreign particles from the workpiece before you apply your hardener and resin.

Clean Surface Before Applying Epoxy

A clean workpiece means that you will have sufficient surface friction between the surface in question and the adhesive. You want the epoxy to bond with the surface, not the dust, dirt, paint, or residue on top of the surface. A great tip is to use some alcohol to clean any sheer metal surface and allow time for it to dry completely before you begin to apply your adhesive.


Apply Your Resin Glue

Now for the simple part, position your workpiece in a manner that allows you to have control of both the applicator and surface area. Once you are happy with how your workpiece has been positioned, you can begin to prepare your adhesive. If you are not working with a dual syringe applicator, you will need to combine the hardener and resin in a 1:1 ratio until you are happy. Once the parts have been combined, you are working on a schedule, which will be dictated by the pot time defined by the manufacturer.

Easy Mix Epoxy Glue Syringe

Apply the mixture to the object’s surface. Do not be shy, apply generously, and do not be afraid to use your glove, an applicator, or stir stick of some type to move the glue around a bit.

Mixing Epoxy with Stir Stick

Next, you can join or apply the object in question to your primary workpiece and allow time for it to set. Consult the manufacturer’s directions to determine the required setting time. Any excess will need to be wiped away using a spare cloth. Allow sufficient time for the adhesive to cure before you can begin using the workpiece for its intended purpose.



Now that you are equipped with the knowledge of what epoxy resin glue is, what its positive and negative characteristics are, what the best epoxy glue available in the market is, and how to apply your resin glues effectively, it is time for you to take your newfound knowledge and put it to the test! Remember as the epoxy and hardener are both toxic before they have been cured, it is necessary to wear the relevant protective gear and to ensure that you are working in a well-ventilated space.



Frequently Asked Questions


Is Epoxy Waterproof?

One of the great characteristics of both epoxy resin and epoxy adhesives is that they are either completely waterproof or at least water-resistant. This is thanks to the two-part hardener and epoxy design which results in the epoxy adhesive being one of the most versatile options to bond surfaces together.


Is Epoxy Stronger Than Glue?

While glue and epoxy may serve the same purpose, at the end of the day epoxy can be used for more heavy-duty purposes and has been formulated with durability and superior tensile strength. This is true for most epoxies, but it is important to note that there are extremely strong conventional glue products available on the market.


Is Epoxy the Same as Glue?

While both glue and epoxy offer the same function, there are significant differences between conventional adhesives and epoxy. Epoxy offers extreme strength for both tensile strength and adhesion. The majority of epoxy adhesives come in two distinct parts, namely the resin and the hardener. Once the two parts are combined, they cure to a very strong substance that bonds to a surface on a molecular level, whereas conventional adhesives only bond the the texture of a surface (which is why you should never try to glue a smooth surface without texturing it first).
