In maintenance, ensuring brackets are in good condition is vital for the safety and longevity of the construction elements they support.  This is an important consideration for businesses in the San Ramon, Dublin, Pleasanton, Livermore, and Danville areas.

The concept of painting brackets – especially metal ones – might seem insignificant at first glance. However, it is important to protect the brackets and enhance the overall appearance of a building. It might seem like a small detail in the grand scheme of a construction or maintenance project. However, its impact on the structure’s integrity, longevity, and appearance is substantial. Ignoring such details can lead to premature wear, safety hazards, and potentially higher costs in the long run.

Corrosion is the worst enemy of any metal. Metallic parts of a commercial building can be affected by corrosion, reducing its overall appearance, structural integrity, and value. Painting or coating metal elements, such as brackets, is one of the most effective ways to prevent them from corrosion. This article explores metal brackets in commercial buildings and how painting them is crucial in preventing corrosion and maintaining a commercial building’s overall appearance and structural integrity.

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.

1. 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 the prepping and priming, and the second was for applying the finishing coat.

2. Challenges faced

During the project, the weather was the only problem our crew encountered 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 excellent primer and finish paint adhesion, and the custom color match was perfect.
