Similar to steel, concrete is frequently roughened prior to application of a coating system to enhance the bond and help maintain adhesion of the applied coating when in service. According to Appendix A7 in the SSPC Joint Su...
Introduction The installation of thermal spray coatings (TSC) or metalized coatings is becoming more common for protection of new and existing structural steel members on locks & dams, bridges, tanks and other industrial struc...
This podcast covers measuring surface profile and discusses two fundamentally different methods for measuring profile. Panelists discuss some of the complications that may occur when using both methods on the same job. The video (...
Abrasive blast cleaning is the process by which an abrasive media is propelled through hoses and a blast nozzle by means of compressed air. The abrasive exits the nozzle at a high rate of speed (velocities approaching 650 – 1,700 ...
Introduction Surface profile is defined as a measurement of the maximum peak-to-valley depth generated by abrasive blast cleaning and impact-type power tools. These operations effectively increase the surface area and provide an “...
What is Surface Profile and Why is it Necessary? Surface profile is defined as a measurement of the maximum peak-to-valley depth created by abrasive impingement against a surface during abrasive blast cleaning operations, or by an...
Introduction Surface preparation prior to coating installation is generally composed of two goals: achieving the minimum specified surface cleanliness, and achieving the specified range of surface profile (surface roughness). Whil...
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 in...
Using project specs and standards to achieve surface cleanliness before coating application is the focus of the newest installment in the PaintSquare Video Learning Center series. “Surface Cleaning” is one of 19 videos...
