Powder Coating Vs. Liquid Paint: Which Is the Best Option for Finishing Your Metal Garage Door?

Your metal garage door is a large structure and one of the few things everybody notices when they enter your home. Garage doors go through a lot of friction and pressure as they are opened and closed a couple of times a day. That said, the type of finish the door has will not only improve the aesthetic appeal of your home but also enhance the door's appearance and durability. So, should you finish your garage door with powder coating or liquid paint? Here is a detailed comparison to help you make an informed choice.

Durability and Resilience

For most people, powder coating is expensive, and that is why they would choose paint. However, compared to liquid paint, powder coats are extremely durable. Powder coating produces a layer that is twice as thick as paint, and it bends and yields to the metal it's applied to. What that means is that it will take twice or thrice as much weather elements, scratches and UV radiation to destroy a powder coated surface. A garage door goes through a lot, and, therefore, it needs to be resilient to nature's harmful ways.

Available Colors and Textures

When it comes to metal coating, some resins are primarily manufactured as powder coating while others like PVDF are made as liquid paint. However, more resins are prepared as powder form, and therefore there is a wide variety of colors and textures to choose from compared to liquid paint. Unfortunately, powder coats are only manufactured in large batches, and it can be very costly to get a custom color or texture in small quantities.

Protection From Corrosion

Unlike liquid paint which wears out fast, powder coating is durable and bonds firmly to the applied surface making a very thick crust. This coat makes it impossible for metal to rust or degrade over time even when exposed to water and other elements. On the other hand, paint tends to peel off when scratched, and this will expose the metal door to the elements making it vulnerable to corrosion.

 Cost of Application

Liquid paint may be cheaper to buy and apply, but it is not less expensive in the long run. Due to its light nature, the paint will be affected by weather, scratches and time, and it will chip quickly, meaning you'll have to reapply it many times. Application of powder coating is efficient and economical because there is less waste. 

It is evident that powder coating has numerous advantages as compared to liquid paint. Ensure that you get the garage door finished by a professional contractor so that the coating can last for decades and maintain curb appeal.
