Comprehensive Guidance for Construction Professionals

The BS ISO 16938-2:2019 standard is meticulously crafted to serve as a definitive guide for construction professionals who are involved in the selection and application of sealants in building projects. It addresses the critical issue of staining, which can significantly impact the aesthetic and structural integrity of buildings. By following the procedures outlined in this standard, professionals can ensure that the sealants used do not adversely affect the appearance or performance of porous substrates.

Why Staining Matters

Staining of porous substrates is a common challenge in the construction industry. It can lead to unsightly discoloration and potentially compromise the material's integrity. This standard provides a reliable method to assess the potential for staining, allowing for informed decision-making when selecting sealants. By adhering to the guidelines set forth in BS ISO 16938-2:2019, construction professionals can mitigate the risk of staining, ensuring that their projects maintain their intended appearance and functionality over time.

Test Without Compression

One of the unique aspects of this standard is its focus on testing without compression. This approach is particularly relevant for applications where the sealant is not subjected to compressive forces, such as in certain types of joints and connections. The test method outlined in this standard provides a clear and concise procedure for evaluating the staining potential of sealants in these scenarios, offering valuable insights into their suitability for specific applications.

Enhancing Material Longevity and Aesthetics

By implementing the guidelines of BS ISO 16938-2:2019, construction professionals can enhance both the longevity and aesthetics of their projects. The standard's emphasis on preventing staining helps to preserve the visual appeal of buildings, while also contributing to the long-term durability of the materials used. This dual focus on aesthetics and performance makes this standard an indispensable tool for architects, engineers, and builders alike.

Who Should Use This Standard?

This standard is designed for a wide range of professionals within the construction and civil engineering industries, including:

• Architects and designers seeking to ensure the aesthetic quality of their projects.
• Engineers focused on the structural integrity and performance of building materials.
• Builders and contractors responsible for the application of sealants in construction projects.
• Quality assurance professionals tasked with maintaining high standards in material selection and application.

Conclusion

The BS ISO 16938-2:2019 standard is an invaluable resource for anyone involved in the construction and civil engineering sectors. By providing a clear methodology for assessing the staining potential of sealants, it empowers professionals to make informed decisions that enhance the quality and durability of their projects. Whether you are an architect, engineer, builder, or quality assurance professional, this standard is an essential addition to your toolkit, helping you to achieve excellence in every aspect of your work.

This standard BS ISO 16938-2:2019 Buildings and civil engineering works. Determination of the staining of porous substrates by sealants used in joints is classified in these ICS categories:

• 91.100.50 Binders. Sealing materials

This document specifies a method for determining the staining of porous substrates (e.g. marble, limestone, sandstone, or granite) by sealants used in building construction. The method evaluates the likelihood of a sealant causing an early stain on a porous substrate due to exudation of materials from the sealant. The outcome of the test is specific to the tested sealant and tested substrate and cannot be extrapolated to other sealant formulations or other porous substrates. During this accelerated test, if the sealant does not stain or discolour the substrates, it does not mean that the tested sealant will not stain or discolour the tested porous substrate over a longer time period.
