Cast Iron is strong and durable, but it can also be difficult to maintain. Over time, the seasoning of cast iron will fade, causing it to rust. This corrosion will then act as a magnet for water, making it much more difficult to clean and maintain the surface of your cast iron.

Appliances such as cookware and ovens are often made of cast iron. These pieces of equipment can be expensive to replace, and also require significant amounts of maintenance. If you are not careful, your cast iron piece could potentially rust away into nothing more than a pile of rusting metal!

This is where you will find yourself faced with a dilemma. You want to keep your cast iron piece in as good of shape as possible, but you also don’t want to experience the frustration of rusting over time. The solution to this situation is to follow the simple steps in this article and learn how to properly maintain cast iron without any welding or other invasive methods.

Before we dive into how to fix cast iron without welding, let’s cover a few key factors that will help you understand why your cast iron has come loose. Most likely, it is not just one issue but a combination of different issues.

Poorly Maintained Cast Iron

Over time, the seasoning (or oil) will slowly dissipate from the cast iron. This is most likely caused by poor maintenance or storage. If you are storing your cast iron in a wet or humid environment, it is likely that the seasoning will not last long.

Storing your iron cast cookware in an oven is also a common reason for scrubbing and re-seasoning your cast iron. The moisture in the oven can create an environment where seasoning can easily deteriorate.


The second factor is corrosion. If your cast iron piece has been in a wet or humid environment, it is likely that it will have developed rust. This causes the seasoning to not be available to protect your iron cast from water and corrosion.

This often happens when there is little to no ventilation in storage areas or your home. If you have a lot of moisture present in your home, it will also be difficult to prevent moisture from seeping into your storage areas.


Pitting is a common problem with cast iron that can lead to rusting. When the seasoning on your cast iron wears off, the metal underneath is exposed. For this reason, it is important to keep your cast iron clean and dry as often as possible.

If you have a lot of grease or oil on your iron cast, it will be more likely to develop pitting. So, it is important to keep your cast iron dry and clean frequently.

Improper Storage or Handling

The last main factor that can cause cast iron pieces to become loose is improper storage or usage of the cast iron. If you are not using your cast iron properly, it can be a risk for its development of rust.

This is because it contains high amounts of iron that can cause corrosion if not properly maintained. This corrosion will ultimately lead to rust, which will break your cast iron piece.

Can I Fix My Cast Iron Without Welding?

Fixing a loose cast iron piece is possible. If you don’t want to weld your cast iron piece, you can still handle it in a way that will prevent it from becoming loose again.

Here are a few ways to repair or fix your cast iron without welding.

Use An Epoxy Primer

The best way to fix a loose cast iron piece is to use an epoxy primer. Epoxies are often used for concrete to make it strong and last longer. They are also a common way to fix loose cast iron pieces.

You can find epoxies sold in different colors at most hardware stores. You can use the epoxy primer on your cast iron piece like you would use on any other concrete project.

Use A Hot Glue Gun

Instead of using an epoxy primer, you can also use hot glue to fix your cast iron piece. This will prevent it from coming loose again. However, this is not the best solution because hot glue is not very strong and will eventually loosen up or break off.

If you want a stronger fix, you should try to find some type of industrial strength glue and stick your cast iron piece with that. You will find different types of industrial strength glues on the market.

Use Putty

Another common fix for loose cast iron is to use putty. You can use this to apply a thin layer of putty on the area where your cast iron piece is loose.

Simply use a putty knife to spread some putty over the area where your cast iron is loose. You will then cover the areas in your putty knife with a cloth or paper towel. This will apply a thin layer of putty over the area and prevent it from coming loose.

Final Words

Now that you know how to fix cast iron without welding, you should be able to maintain it easily. However, if it becomes loose again, it is important to fix it quickly. This is because a loose cast iron piece can cause damage to your cookware and shorten the life of the cookware.
