About the project

Custom Painting, Inc. recently completed a bracket painting project in Milpitas, CA. In this project, our crew painted a total of 76 horizontal brackets. We do similar work a few times a year, making us a reliable company for this painting job.

The painting process

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

After priming, our crew used the Sherwin-Williams Pro Industrial DTM Acrylic as a finishing coat. It was tinted to match the adjacent metal rails to which the brackets were welded. 

The project took two days to finish. The first day was for prepping and priming, and the second was for finishing coats.

Challenges faced

Throughout the project, our crew only encountered problems with the weather due to the frequent rain this time of the year. That is why we had a 4-day window (one day before, two days for application, and one day following) to complete the work. Luckily, the weather cooperated, the team had excellent primer and finishing coat adhesion, and the custom color match was perfect.

In general, the project was a success. Read on below to learn more about the importance of painting brackets in commercial construction.
