Powder Coating

How it works


Powder Coating is environmentally friendly and a great alternative to liquid paints. During the powder coating process, it releases a low, if any, VOC (Volatile Organic Compounds) into the atmosphere. Powder coating needs a clean, rough surface to guarantee good adhesion, so all surfaces are sand blasted in preparation for the coating process. The spray gun that is used to apply the powder sends out an electrostatic charge to the powder particles. Those particles are drawn to the grounded metal part and wraps around the material. Once the powder is applied the material will go into a 400 degree oven to cure.

*If any additional handing/cleaning is necessary there may be an additional cost for additional prep time
*If any welds break during sand blasting, we are happy to re-weld the material at an additional cost
*If the item has been previously powder coated the existing coating must be removed, and an additional charge will apply.

Frequently Asked Questions

How should I prep my item for powder coating?

All parts must be disassembled and all materials that will melt in 400 degrees (rubber/plastic, bearings) removed. Any parts with oil or grease on them need to be power washed before bringing them in. Oil and grease can contaminate our sand in the sandblasting booth.

What happens if the item has pitting marks from rust?

Parts that have pitting marks from rust, could potentially experience more pitting during the sand blasting process. If your material has severe pitting marks, powder coating will not fill in those marks, leaving them still visible. There are some powder coating finishes that can help “cover up” the pits i.e. texture or hammer finished, but the powder will not fill in the pit marks.

Can you powder coat parts that are cast?

We do not guarantee powder coating on parts that are cast or material with poor welds. Due to the material and/or the poor welds some areas can experience “outgassing” or bubbles.

What is your turnaround time?

We strive to keep our lead time around a week and a half. During the busy summer months our lead time can reach 3 weeks.

How are the items prepped for powder coating?

In order to guarantee adhesion of the powder coating, all parts will be sand blasted and be exposed to 400-degree heat. Unless other arrangements have been made (example: steam cleaning).

Can you powder coat an item that is spot welded together?

We recommend that all material is completely welded at connection points. For example: If a handrail does not get completely welded around the pickets over time those areas that are exposed will rust. Midwest Welding & Machine is not responsible for future rust on material that is not fully welded.

Can you powder coat an item that is already powder coated?

Yes, but first the existing coating must be removed.

What should I use to clean my powder coated items?

Use warm water with a mild soap and a soft cloth. We do not recommend using chemical cleaners (brake cleaner, acetone, etc.) to clean the powder coated surface. If the powder coating is exposed to harmful chemicals, clean immediately.
