This seminar explains how surface protection slows the main deterioration processes, compares the EN 1504-2 product types and generic coating chemistries, shows how to select a system for atmospheric, splash, immersion and chemical exposure, and sets out the preparation, testing and maintenance that make coatings last.
Learning objectives
- Explain how carbonation, chloride ingress and chemical attack damage concrete, and how surface protection slows them
- Compare hydrophobic impregnations, impregnations and coatings under EN 1504-2, including anti-carbonation acrylics, epoxies and polyurethanes
- Select a surface protection system for atmospheric, splash, immersion and chemical exposure
- Specify surface preparation, film thickness, testing and maintenance for durable coatings on concrete
