Asset owners are tasked with maximizing their return on investment (ROI). This can pose challenges when deciding where to utilize their limited resources, independent of whether the project is new construction or rehabilitation of an existing asset. While most can agree that the success of a project can be determined by maximizing longevity or “quality […]
Permeability of Applied Paints & Coatings… Do I want a permeable coating or not? The answer to the question posed is based on the substrate and the service environment. All paint and coatings are permeable to water, just to different degrees. A high resistance to permeability is likely desirable for lining applied to the interior

Stripe Coating The Protective Coatings Glossary (SSPC 00 – 07) defines a “Stripe Coat” as: “A coat of paint applied only to edges or to welds on steel structures before or after a full coat is applied. The stripe coat is intended to give those areas sufficient film build to resist corrosion.” SSPC Paint Guide

What is considered a good coating specification and how is it written? Specifications are essentially a project “roadmap” that should convey the project scope of work and the requirements in a simple, clear, concise and easy to read format. A well written specification allows the reader to easily navigate, understand, and use the document. The

During any crime scene investigation, there is the collection of samples (evidence) that are subsequently analyzed in a forensic laboratory and used to help solve the crime. This process is very similar (albeit a lot less serious) when a coating fails prematurely. Samples of failing and non-failing coating are gathered as evidence, along with a
Introduction Occupational exposure to respirable crystalline silica in the coatings industry may occur during, or while working alongside dust-producing operations involving a concrete substrate, while using sand as an abrasive (silica may be present in the abrasive), or as a component of the coating (silica may be an extender used in coatings). Operations using sand

Background Color is used in the coatings industry for safety (e.g., safety yellow), identification (e.g., pipes coated blue indicate gas flowing through them) and for branding (e.g., company color schemes). The color of a protective coating changes over time; these changes may be caused by aging of the coating and/or exposure to solar radiation (ultraviolet

A 1930s-era riveted steel tank with a capacity of 1.5 million gallons was one of the largest water tanks in the world at the time of its construction. A radial cone-design tank with a 6-foot-diameter riser and 20 legs, it is approximately 175 feet in height and 80 feet in diameter. The available painting history

Proper surface preparation is one of the most critical steps towards maximizing the life of a coating system. If coatings are applied to improperly prepared surfaces, the system is much more likely to fail prematurely. Abrasive blast cleaning is the most common and productive form of surface preparation. Abrasive selection is a key component to
