Understanding different types of sealants

The CPD provides an introduction to specifying sealants. You will gain a clear understanding of the different types of sealants, joints and applications and how to use them correctly on your projects.

Learning Aims

• Sealant Types: Learn about the different categories of sealants, including their chemical compositions, physical properties, and typical uses.

• Application Considerations: Understand the factors that influence sealant selection, such as environmental conditions, substrate compatibility, and movement requirements.

• Best Practices: Gain insights into proper sealant application techniques, including surface preparation, joint design, and tooling.

• Case Studies: Explore real-world examples of successful and unsuccessful sealant applications to highlight the importance of making informed choices.

By the end of our course, you will be able to :

• Identify and classify different types of sealants: Participants will be able to differentiate between various sealant categories (e.g., silicones, acrylics, polysulfides) based on their chemical composition and key properties.

• Understand the factors influencing sealant selection: Participants will be able to recognize and evaluate the critical factors that impact sealant performance, such as substrate compatibility, environmental conditions, movement requirements, and design considerations.

• Apply knowledge to practical scenarios: Participants will be able to apply their understanding of sealant types and selection criteria to real-world situations, such as specifying appropriate sealants for specific building elements and design challenges.

• Appreciate the importance of proper sealant application: Participants will recognise the significance of proper sealant application techniques, including surface preparation, joint design, and tooling, in achieving optimal performance and durability.

• Recognise the potential consequences of incorrect sealant selection: Participants will understand the potential risks and costs associated with using the wrong sealant, such as premature failure, water ingress, and structural damage.

• Develop best practices for sealant specification and management: Participants will gain insights into best practices for specifying, procuring, and managing sealant installations to ensure successful project outcomes.
