Can You Put Epoxy On Copper? (How To)

Epoxy comes in a wide array of forms, many of which can be applied to copper. For example, there are epoxy putty sticks that can be used for emergency repairs to pipes, and even epoxy resin, which is a common material in woodcrafting. Because of all these varieties available, it can be difficult to know whether or not epoxy can be used on certain surfaces. Let’s take a look at the answer to “can you put epoxy on copper? (how to). 

While you can put epoxy on copper, it may not be the ideal solution. In fact, the copper will need to be cleaned of oxides before the epoxy can be applied. So, it is possible, but you may want to consider other potential options instead of epoxy to apply to copper.

You should always refer to the label on the epoxy you are using, since this will provide you with a slew of useful information that you should know before using the epoxy. Because of the sheer different types of epoxy on the market, the actual usage and applications can vary greatly from one to the other. Referring back to the label will help ensure you don’t damage the copper surface, while also preventing harm to the person applying the epoxy on copper.

Should You Put Epoxy On Copper?

Whether or not you should put epoxy on copper really depends on the type of epoxy you want to use and why you want to put it on copper in the first place. 

The problem you should look out for when putting epoxy on copper is adhesion. If the copper surface isn’t properly prepared, the epoxy won’t be able to correctly bond to the surface. This means you would be essentially wasting the epoxy, as well as your time.  

Furthermore, you should be on the lookout for the fumes and odors that epoxy can give off. The fumes and odors can have an adverse effect on your health and shouldn’t be taken lightly.

Keep in mind, however, that some epoxy is less odorous than others. Despite this, you should always err on the side of caution and only use the epoxy in an area with good ventilation. Furthermore, immediately discontinue use if you start to feel faint, lightheadedness, or get a headache. If you experience any of these symptoms, move to an area with fresh air. 

What Tools Do You Need To Put Epoxy On Copper?

Applying epoxy on copper doesn’t require many tools. Along with safety items, such as goggles and rubber gloves, you will also need just a few items that you probably already have on hand.

The tools needed to put epoxy on copper can vary from one job to the next. On average, however, you will need an old rag and cleaning solution to clean the copper surface, water to rinse the copper clean, and then a rag to wipe it dry.

If the copper surface is rough or has rust on it, you may need to sand it a bit before cleaning. This will require using either a piece of sandpaper or an electrical sander. If the area needing sanding is rather small in size, a piece of sandpaper will usually do the trick. If, however, the area is much larger, you may want to use an electric sander as this will make the process much easier and quicker.

What Preparations Do You Need To Put Epoxy On Copper?

For just about any project, you will need to prep the surfaces or items you are working with before you start the job. And putting epoxy on copper is no different. 

Before putting epoxy on copper, you will first need to make sure the copper surface is smooth and rust free. This may require lightly sanding the surface with a piece of sandpaper. Once smooth, wipe the copper surface clean with a rag dampened with soapy water.

Rinse the soapy residue off the surface and then wipe dry with a clean towel. You want to make sure that the copper surface is completely dry before applying the epoxy to it. Epoxy cannot stick to a surface if it is damp. 

Some people prefer to apply a primer to the copper before adding the epoxy. This isn’t a hard and fast rule that every copper needs a primer, but it can help the epoxy to adhere better to the surface if you prime it first.

There is even some epoxy that has primer already added to it to increase the product’s ability to stick to surfaces much better. 

How To Put Epoxy On Copper

Applying epoxy on copper isn’t a difficult process, but it does require a little preparation to the copper surface. Additionally, you should read the application instructions, as well as the warnings listed on the epoxy label. This will help prevent damage to the surface the epoxy will be applied to. 

To put epoxy on copper, prep the copper surface by first sanding out any rough or rust spots with sandpaper. Then clean the surface with soapy water. Rinse the copper surface with water and then wipe it dry with a towel. Then simply spread the epoxy over the copper. 

If you are using a primer, apply it to the copper surface after cleaning the copper but before spreading the epoxy. The primer will need to dry completely, about 24 hours, before you can apply the epoxy. 

The epoxy will need to dry completely before you can use the copper item. The length of time it takes to dry, however, depends on the type of epoxy. For example, some brands of epoxy putty can start to harden in as little as 3 minutes, forming a strong bond within 5 minutes. Epoxy resin, however, can take 72 hours to cure.

Remember that the curing and drying times can vary depending on several factors, including the resin thickness, temperature, and humidity levels.
