Client and Facility Overview

Brenntag Southwest Inc, a branch of the globally recognized Brenntag, is a premier chemical and ingredients distributor.

Located in Lancaster, Texas, this facility spans approximately 10,000 sq. ft. and plays a crucial role in the company's distribution network.

Decision Driver and Timing

The main driver for this project was the critical need to recoat bulk storage tanks containing caustic, flammable chemicals. The tanks could not be emptied, precluding the use of abrasive blasting or other profiling methods, thus requiring specialized techniques to ensure safety and efficacy. The failure of existing coatings posed significant operational risks, urging immediate action to prevent any potential hazards or disruptions in service.

Scope of Work

Acid Load Out Floor

Removal and Preparation: Removed the existing coating using diamond grinders, which provided a smooth and clean surface suitable for coating.
Coating Application: Applied one coat of Sherwin Williams 3569 chemically-resistant primer followed by two coats of Sherwin Williams 3741 chemically-resistant top coat.

Tank Painting

Coating Removal: Utilized sandblasting with a water additive at the nozzle to remove the existing grey coating effectively without creating excessive dust or risk.
Coating Application: Applied one coat of Sherwin Williams Macropoxy 646 primer and one coat of Sherwin Williams Acrolon 218 top coat.
Stenciling: Installed new stencils and stickers on each side of the tank.

Notable Details

Given the precarious nature of the materials involved, a high degree of caution and meticulous attention to safety protocols was paramount throughout the project. Adhesion testing was used instead of traditional profiling methods to ensure a strong bond for the new coatings.

To address safety, operational and financial risks, we opted for heavy power washing and hand rolling instead of blasting and spray-painting. These methods, while time-consuming, minimized the potential for hazardous material exposure and maintained operational integrity.

Safety

All work followed strict OSHA guidelines as well as Brenntag's internal safety protocols. Painters USA ensured that every step was taken with the utmost care to protect employees and the environment from potential hazards.
