Concrete floor coating systems are frequently specified to be textured to improve traction. The surface texture, however, is only one variable that affects the slip resistance of a surface. Slipping can arise from a failure of traction on the interface between, for example, the footwear and the walking surface and is affected by the floor […]

Two standards address the use of non-destructive dry film thickness gages: ASTM D7091, Standard Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals and SSPC-PA 2, Procedure for Determining Conformance to Dry Coating Thickness Requirements. Both address the need to compensate
As seen in the Fall Edition of PaintSquare Press News The Surface Preparation Hand Tool Cleaning Standard (SSPC-SP 2) was first published as a temporary specification in August 1952 (SSPC-SP 2-52T), only two years after the Steel Structures Painting Council was founded (1950). The standard was developed primarily for maintenance of existing coating systems when

Two standards address the use of non-destructive dry film thickness gages: ASTM D7091, Standard Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals and SSPC-PA 2, Procedure for Determining Conformance to Dry Coating Thickness Requirements. Both address the need to compensate for substrate/surface conditions
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 Surface Preparation Standard SP 13/NACE No. 6, Surface Preparation of Concrete, the depth of surface profile required depends

According to SSPC: The Society for Protective Coatings, Paint Application Standard No. 2 (SSPC-PA 2), Procedure for Determining Conformance to Dry Coating Thickness Requirements, is one of the most frequently downloaded standards from the SSPC Marketplace. Measuring coating thickness is one of the most commonly specified quality control processes, and SSPC-PA 2 is recognized across
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 structures. While the installation of thermal spray coatings is typically more labor intensive and more costly than traditional liquid-applied coatings systems, the

Introduction According to Wikipedia, an exemplum (Latin for “example”) is a moral anecdote, brief or extended, real or fictitious, used to illustrate a point. While I wouldn’t consider deciding whether to perform painting work in a shop or in the field a “moral issue,” this story-telling approach is intended to provide a more interesting way

Weathering steel, often referred to by the genericized trademark COR-TEN steel, is a group of steel alloys developed to form a stable corrosion-resistant surface after several years exposure to weather, potentially eliminating the need for painting in many environments. U.S. Steel (USS) holds the registered trademark on the name COR-TEN, which refers to the two

Independent verification of coating system performance based on laboratory testing and/or field exposure is a critical component to coating system selection. For a given coating system, there may be six or eight manufacturers. It is not safe to assume that all coating systems within a given generic category are created equal. Therefore, careful evaluation of
