Surface Preparation Standards, Part 1 – Evaluating Surfaces Throughout Finishing Processes

Surface preparation can account for up to 40 percent of structural steel painting and repainting jobs and the life of anti‐corrosion coatings on a steel surface largely depend on how thoroughly the surface was prepared before painting.

At Rosler, we have extensive experience evaluating structural steel surfaces for coating before and after shot blasting. This knowledge of surface preparation standards and the widely used ISO and SSPC standards guide us in developing systems to expertly prepare and repair structural steel throughout its lifespan.

The Standards

Evaluating rust and mill scale pre- and post-shot blasting is a must. It is important to clearly specify the quality of the surface prior to preparation as well as the surface conditions after preparation. As a result, standards were developed to visually assess the initial surface conditions and the quality of the required surface preparation relative to the initial steel surface conditions.

The dominant and widely used standards for evaluating rust and mill scale are ISO 8501‐1:2007 (based on the Swedish Standard SIS 05 59 00) and the SSPC (Steel Structures Painting Council). While different in some minor details, these standards are practically identical.

Shotblasting – How to measure your surface profile

Shotblasting of steel plate, profiles, construction, and fabrications is a process to clean, descale, provide a specified surface profile and edge break as a surface preparation.  This process takes place prior to a coating or paint application to maximise the adherence potential and corrosion control.

This is a document made up of five parts  on  “How Do You Make Your Coatings Stick Better?”

Section 1 – Specified Consistency
Section 2 – Measurement Terms
Section 4 – Cleanliness and Surface Profile
Section 5 – Recognising Steel Processes (for hardness of steel)
