Industrial coatings project specifications invoke many standards and inspection check points that require visual acceptance. Proper illumination of the work area is vital when determining an acceptable product. If there is insufficient light, it is unlikely that a quality inspection of workmanship can be performed. But requiring excessive light and it may not be practical […]

Why do we need to measure ambient conditions? Ambient conditions are the prevailing conditions of air temperature, the moisture content of the air (relative humidity), and the temperature at which condensation will occur (dew point). Most coating specifications have set requirements for monitoring and documenting results for surface and air temperature, relative humidity and dew

There are many challenges associated with cleaning and painting commercial buildings. Questions often arise regarding surface preparation, application and final thickness or appearance. Three of the many questions our consultancy group has encountered during the cleaning and painting of buildings are addressed in this article. The questions should be familiar situations to those in the

Introduction Most industrial and marine protective coatings rely on a mechanical bond to the substrate to remain attached while in service. This bond is generally provided by a surface profile or anchor pattern that is imparted into the surface prior to application of the coating system and effectively increases the surface area of the substrate

“Do I have to maintain inspection gage calibration and certification? Why don’t they retain their calibration over time? Do I need to verify gage accuracy on a regular basis? How often? What is the difference between calibration and verification of accuracy?” These are common questions in the coatings industry. A simple answer is that without
New SSPC/NACE wet abrasive blast cleaning (WAB) standards were approved in August 2015. The standards define five degrees of cleaning that are created using a mixture of abrasive and water. The mixture is created in one of three ways: water is injected into the dry abrasive blast stream, abrasive is injected into a pressurized water

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

Positive Material Identification has become a convenient and reliable way to determine the alloy compositions of materials. One of the greatest advantages of using a PMI unit is its portability, weighing approximately 5-8 lbs. with the battery loaded into the unit, it can be easily transported and used in confined areas or field applications. With the

An ounce of inspection may be worth a pound of do-over. Cleaning and painting commercial buildings comes with extensive challenges. The paint does not always perform as expected. In some cases, poor performance is caused by problems with the building itself. In others, it is caused by a failure to comply with the specification and
