Painting brackets may or may not be necessary. However, it can provide benefits such as protection against corrosion and enhancing aesthetics. The decision to paint brackets is based on material, environment, local building codes, and manufacturer recommendations.

This article delves into the crucial role of painting brackets in commercial buildings’ overall health and functionality. We’ll explore the importance of this seemingly small task in building and maintenance protocols, from improving structural integrity to preventing corrosion and enhancing visual appeal. Furthermore, we uncover the benefits and best practices encompassing the painting of brackets in commercial settings, emphasizing its impact on project success and building lifespan.

Bracket Painting Project by Custom Painting, Inc.

Custom Painting, Inc. recently finished a bracket painting project in Milpitas, CA. In this project, we painted a total of 76 brackets, which were all horizontal. We are used to this type of project as we do similar work a few times a year, making us a reliable company for this paint job.

The painting process

Our crew first primed the brackets using Sherwin Williams Macropoxy 646, a high-solid, high-build, and fast-drying polyamide epoxy designed to protect steel in industrial environments. 

For the finishing coat, our crew used the Sherwin Williams Pro Industrial DTM Acrylic, a water-based and corrosion-resistant acrylic coating formulated for interior and exterior applications, to match the adjacent material rails to which the brackets were welded.

The project took two days to complete; the first day was for prepping and priming, and the second was for applying the finishing coat.

Challenges faced

The weather was the only problem our crew encountered throughout the project due to frequent rain this time of the year. For this reason, the team had a 4-day window (one day prior, two days for application, and one day following) to complete the work properly. Luckily, the weather cooperated, the team had a great adhesion of the primer and finish paint, and the custom color match was perfect.
