Coating Failure Analysis Learning Series – Part 5 – Field Microscopic Examination

Coating Failure, Coatings, Concrete Floors, Video / KTA Staff

Welcome to the KTA Coating Failure Analysis Video Learning Series! This is a six-part video series that demonstrates the field and laboratory methods that were used to determine why a new coating system applied to a previously painted concrete floor had failed. Each part is standalone, addressing a different aspect of the evaluation, but when viewed […]

Pitting Due to Stray Current Corrosion

3 Comments / Coating Failure, Coatings, Corrosion, Pipeline Coatings / Valerie Sherbondy

Section loss of pipe wall is of great concern in the pipeline industry. Reduced wall thickness due to pitting corrosion can adversely impact pipeline integrity; the results of which can be catastrophic depending on the product that the pipeline is transporting. In order to reduce the opportunity for corrosion, the use of protective coatings is

Can Pre-Project Coating Testing Lead to Post-Application Performance?

Coating Standards, Coatings, Lab Testing / Valerie Sherbondy

Many agencies and facility owners require coating testing of products and systems prior to their use on a coating project. This is not an original concept; developing a qualified products list (or QPL) is becoming more commonplace, as not all coatings and coating systems are created as equals, even if they are in the same generic

Mitigating Moisture in Concrete and Masonry Walls

1 Comment / Coating Standards, Coatings, Commercial, Concrete Floors, Concrete Walls, Inspection, Moisture / Ken Trimber

In commercial buildings, the uncontrolled intrusion of moisture into concrete and masonry walls may have costly consequences. Moisture supports the growth of mold, and causes wall coatings to blister and peel. It also saturates insulation, reducing energy efficiency. In extreme cases, moisture intrusion leads to spalling and could even necessitate wall replacement. Coatings and water

Common Causes of Blistering and Bubbling in Industrial Coatings

18 Comments / Coating Failure, Coatings, Moisture / KTA Staff

Blistering formation in high performance industrial coatings is a common phenomenon. Understanding why blisters form is sometimes very simple and in other instances quite complex. For example, understanding and describing the process by which moisture migrates through a coating film at a molecular level to achieve equilibrium can be very complex, especially to the layman.

Painting Bolted Connections for Bridges

4 Comments / Bridges, Coating Standards, Coatings, Lab Testing, Specifications / Ken Trimber

High-strength bolts have been used to assemble steel structures for over 60 years, supported by research conducted by the Research Council on Riveted and Bolted Structural Joints (RCRBSJ). RCRBSJ was founded in 1947 but is now known as the Research Council on Structural Connections (RCSC). Despite the long history of use, there is still confusion

Treating Exterior Concrete Walls with Coatings

Buildings, Coatings, Commercial, Concrete Walls, Moisture, Surface Preparation / KTA Staff

Concrete is widely used in commercial building construction and is present in a number of forms: poured concrete, tilt-up concrete and concrete masonry units (CMU). CMU also comes in a number of different forms: standard block, split-face block and scored block. Because of the dull gray appearance of concrete, however, coatings are usually applied in

Selecting Coatings for Hospitals by Service Area

Buildings, Coatings, Commercial, Hospitals, Specifications / Jay Helsel

Coatings used in hospitals and healthcare facilities must be kept clean, which typically requires frequent scrubbing and disinfecting. These coatings must therefore be resistant to abrasion and to the chemicals used in cleaning products. Meeting these requirements typically indicates the need for high performance coatings. But there are often other requirements for coatings used in

Major Consequences of Minor Defects in Exterior Pipeline Coatings

5 Comments / Coating Failure, Coatings, Pipeline Coatings / KTA Staff

A minor defect in an exterior pipeline coating can have huge consequences. Consider the fire from the Spectra Energy 30” buried pipeline in Salem Township, Westmoreland County, PA on April 30, 2016. Preliminary findings from the investigation indicate that a pinhole or flaw in the tape wrap used to protect the field welded joints may
