Brushed Off: Latest Contractor Tools for Performing Hand Tool Cleaning

Surface Preparation / By

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

User Options for Surface Roughness Compensation when Measuring Dry Film Thickness of Coatings on Metal Surfaces

Dry Film Thickness, Surface Profile / By

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

Addition of Appendix 10 to SSPC-PA 2, Procedure for Determining Conformance to Dry Coating Thickness Requirements

Coating Standards / By

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

Surface Preparation of Steel Prior to Application of Thermal Spray Coatings

1 Comment / Coatings, Steel, Surface Profile, Thermal Spray / By

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

Weathering Steel – Use and Preparation When Left Uncoated and When Coated

1 Comment / Bridges, Corrosion, Weathering Steel / By

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

Coating System Selection Based on Performance Evaluations

Coatings, Lab Testing, Specifications / By

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

Using Scanning Probe Technology to Measure Coating Thickness

Coating Standards, Dry Film Thickness, Inspection / By

Introduction Coating thickness measurement is one of the most common quality assessments made during industrial coating applications.  SSPC-PA 2, Procedure for Determining Conformance to Dry Coating Thickness Requirements is frequently referenced in coating specifications.  As SSPC-PA 2 has evolved over the past four decades, a number of procedures and measurement frequencies are referenced in both

Surface Soluble Salt Measurement – Conductivity Verses Ion-specific Methods of Analysis

Corrosion, Inspection, Instruments, Specifications, Surface Cleanliness, Surface Preparation / By

Chemical contaminants on a surface can include chlorides, ferrous ions, sulfates and nitrates, among other types of soluble salts. Chloride may come from deicing materials or marine/coastal environments, ferrous ions are a by-product of corrosion, sulfates can be airborne, particularly in industrial environments (e.g., coal-fired power plants) and nitrates may come from the soil (e.g.,
