Refurbishing Old Radiator with Powder Coating

Posted on: March 1st, 2017 by byersbushblog

What do you do with an old cast iron radiator that is sitting in your home looking grimy and old? Would you consider refurbishing it or just throwing it out? If you want to bring back its old glory, one of the best ways to do it is to have the radiator powder coated. By undergoing the powder coating process, the cast iron radiator can gain a fresh new look and outstanding finish that will outshine even the best painting job. How do you do it?

Cast Iron

First off, why is cast iron used for radiators? This material was the choice for radiators even when it was first introduced during the Victorian era. The radiators brought about an air of authenticity to the period aside from the timeless beauty it added to the contemporary interiors at that time.

Aside from the outward appearance, cast iron is considered dense and has great mass that allows it to efficiently generate heat. This is why cast iron radiators are often believed to stay warm longer compared to other types of radiators. Even engineers and architects realize this unique characteristic of cast iron, which is why it has remained one of the more popular choices for heating element not only in many homes, but in buildings as well. Cast iron radiators have proven to be effective in negating the effects of dampness and condensation.

Coating Cast Iron Radiators

When considering how to coat cast iron radiators, it is important to note that it has a textured finish. This means that it will not be like steel radiators that have smooth finishes. If you want to paint your cast iron radiators you need to make sure that you use a low-odor paint. This will ensure that it will not give off fumes and foul smell as it begins to heat up.

The rougher finish is not that difficult to deal with so painting can be done easily. You can use a primer first before painting the radiator with a top coat. It is better to spray paint the radiator rather than using a hand brush. This makes it easier to reach between the columns and get a more even coating.

To get a tougher finish, consider powder coating the cast iron radiator instead. This will be subjected to sandblasting before coating. This will remove any old paint or coating and help you get a cleaner surface that will allow the powder coating to bond better with the cast iron. You have a choice of different colors as well as finishes for your radiator.

Despite the rough characteristic of the cast iron, you can achieve a smoother finish by using powder coating. The important thing to remember is to never expose the cast iron radiator to prolonged baking. This is because the gaskets will tend to deteriorate faster and may even result in leaking, which will invalidate any manufacturer guarantee that may still exist.

The size of the radiator will dictate just how much you will spend in refurbishing it using powder coating process. On the average, a small cast iron radiator may cost you around $28. This will include the entire powder coating process where the powder will be electrically charged and applied to the radiator surface using a special gun.

This allows for the surfaces to be coated uniformly. The radiator will be cured to about 400 degrees in an oven. This is beyond the 180 to 250 degrees operating temperature of the radiator so you need to make sure that it does not stay in the oven longer than necessary. When properly coated, you will end up with a durable, odorless, and scratch-resistant radiator surface. Normally, the ends and the tank of the radiator will be powder coated but not the fins. This is because the static electricity used to apply the powder coating may fill in some of the fins, which in turn will reduce the efficiency of the radiator.
