That is the question. Several of my steel sculptures have been
powder coated, while others have been left in their natural steel state to rust or patina. I have been asked several questions regarding why I’ve chosen to powder coat the sculptures, how does the process work and how long will the powder last. I chose to powder coat because I love the variety of awesome colors to choose from, especially the metallic colors. It provides the sculptures with an added richness that enhances their uniqueness to me. I personally am drawn to the color that enhances the designs and further draws my attention to the sculpture. I’m sure that others will disagree with me by preferring my sculptures in their natural state to rust or patina; which is fine if that is their preference. Should one want a commissioned sculpture by me, I do provide the choice of natural, paint or powder; it all depends on the art lover and their preference.
Now, what is powder coating, you ask? Powder coating is a surface finishing technique of applying dry paint to a metal surface, such as cars, rims, or metal art. The metal being powder coated is first cleaned using a variety of methods such as sandblasting or given a chemical bath to ensure that the powder will adhere to the surface. The powder is a thermosetting powder usually made up of polyester, epoxy, and acrylic resin combined with other compounds. The powders resemble fine grain dust that comes in a multitude of colors and textures. The thermosetting powder can be applied in two methods:
1. Dipped in a fluidized bed of powder that’s been electrostatically
2. Electrostatically charged powder is sprayed onto the
The coated part is then placed in a special oven where the powdered particles melt and coalesce into a continuous film.
Once the part is removed from the oven, it needs to be cured.
Curing time depends on the thickness of the powder and size of the object that was powder coated.
Powder coating provides a hard surface that is resistant to abrasions and is very tough. This technique is generally used to prevent corrosion of the metal. Prevention of corrosion is a key reason that I chose to use the powder coating method on some of my sculptures instead of painting. The sculptures can be placed outdoors and stand up to the variable weather changes from season to season. Paint has a tendency to chip while powder coating retains its elasticity leading to a more durable, scratch, chip and flake resistant product.
Will powder coating rust or how long will it last? That’s a very good question without a definitive answer. It depends. Depends on the conditions, how well the powder adhered to the piece and how the piece is going to be used. It may last for years or it may wear in a short period of time.

Here I am working on one of my current projects. The process started out on paper after much research. After I decided on how I wanted the end result to turn out, I gathered the needed materials. Once I had those in place, I did a dry run, i.e., I assembled all the pieces on a flat service. This accomplished several things. The first, provided me with a visual on how the pieces would fit together; second, it provided a quasi-visual of the final assembled piece; and third, it tells me if I need to make adjustments, swap out components and lastly if I need additional components.
The slideshow below, shows me in the assembly (fabricating) process. Here I am using a mig welder to weld the steel parts together.
Can you tell what the final project will be? Not yet? Leave me your best guess in the comments section.
Stay tuned as the project takes shape...
I often surf the Internet for sculptures and other art mediums to see what sparks my interest--or catch my eye if you will. I also look through magazines and catalogues for eye-catching designs or "the look" to spark my imagination. Everything that I look at, whether in print, on the television, or in real life, I examine from an artistic point of view to see if there is art value in it. As a self-taught artist, this is how the process begins for me and my very active imagination.
Art value to me is something that visually stimulates my spark of imagination or rather my very active imagination. An item may have the lines or curves that will drive me to distraction and I end up taking out my sketch pad and sketching out several designs that move me. However, as most other artists know, once I start to paint or fabricate, the sketch pad falls to the wayside and I create solely from my creative "mind’s eye". Most of my designs do
actually start out on paper, however, without fail, the sketched design never materializes as the end product as my mind takes over and I end up with a completely new design.
I often wake up in the wee hours of the morning with a new design that I must start on right away. To say that I am then consumed is a gross understatement...my family likes to say that I am possessed or obsessed (depending on which one you ask) with the work until it is completed to my satisfaction. Which can take hours or days...most of my work does not stretch out into months, at least not the creating part of it. The finishing process may stretch out depending on the work in progress for example, one of my steel sculptures, if it is to be painted or powder coated will end as the finishing process takes longer to complete.
The creative process for me is more about the art of discovery rather than the actual creation. What I mean by that is the discovery process is a culmination of the sketched design that I mentioned above and the finished piece. Remember that I do not often stick with the work on paper rather I end up with an object of discovery as my imagination takes over and completes the finished art piece.
So tell me, what sparks your creative juices?
As an artistic engineer, I want my creative spirit to inspire the viewer to think outside the box of their normal boundaries. I want viewers to interpret my artwork into whatever moves them beyond their normal boundaries to see what can be instead of just what is. I feel that abstract artwork does just that--move you beyond the normal. LJS
