What is BS EN ISO 1938:2014?

BS EN ISO 1938:2014 is an international standard that sets guidelines for the preparation of steel substrates before applying paints and related products. It provides detailed specifications on how to achieve the required level of cleanliness and surface roughness, ensuring optimal adhesion and performance of coatings.

Importance of Surface Preparation

Surface preparation is a critical step in the coating process as it directly affects the quality and durability of the finished product. Properly preparing the substrate ensures that the coating adheres well, preventing issues such as peeling, cracking, or premature failure.

BS EN ISO 1938:2014 serves as a comprehensive guide for manufacturers, contractors, and coating applicators, helping them understand the necessary steps and requirements for achieving the desired coating performance.

Main Requirements of BS EN ISO 1938:2014

The standard outlines various aspects of surface preparation, including the acceptable methods, equipment, and materials to be used. It defines the minimum cleanliness and roughness criteria based on the type of coating system to be applied.

Some key requirements include:

Removal of contaminants such as dirt, rust, oil, grease, and mill scale.

Achieving the specified surface profile through techniques like abrasive blasting or mechanical cleaning.

Verification of surface cleanliness and roughness using appropriate test methods.

Proper storage and handling of prepared surfaces to avoid recontamination.

Benefits of Following BS EN ISO 1938:2014

Complying with BS EN ISO 1938:2014 offers several advantages to both coating applicators and end-users:

Enhanced coating performance and durability.

Reduced risk of premature failure or corrosion.

Consistency in surface preparation practices across different projects.

Improved transparency and communication between stakeholders.

Greater confidence in the quality and longevity of coatings.

Adhering to this standard helps ensure that coating application processes are conducted efficiently and effectively, resulting in long-lasting and high-performance coatings.

In conclusion, BS EN ISO 1938:2014 plays a vital role in guiding manufacturers, contractors, and coating applicators on how to adequately prepare steel substrates for optimal coating performance. By following the standard's requirements, the industry can achieve consistent and reliable results, leading to increased product durability, reduced maintenance costs, and improved customer satisfaction.
