TS EN 1504-2

TS EN 1504-2 is the standard for products and systems used to protect concrete surfaces within the broader field of concrete structure protection and repair. It addresses materials intended to improve the durability of concrete and reinforced concrete, whether they are used on new construction or in maintenance and repair work. In practical terms, it provides the framework for identifying these systems and for assessing their performance, safety-related aspects, and conformity.

The protection methods it brings together

The standard covers three surface protection methods: hydrophobic impregnation, impregnation, and coating. In general technical terms, hydrophobic impregnation is used to make the concrete surface water-repellent and reduce water uptake; impregnation can penetrate the surface and modify its properties; and coatings form a continuous protective layer on the concrete. These distinctions matter because each method responds differently to exposure conditions, substrate condition, and expected service life.

Where the scope ends and how it relates to other standards

• It focuses on identifying products and systems intended for surface protection of concrete.
• Its scope includes performance requirements, including durability aspects, and evaluation of conformity.
• It is relevant to new concrete as well as maintenance and repair work.
• Flooring systems in buildings that are not intended to protect or reinstate the integrity of a concrete structure are covered by EN 13813.
• Where such products and systems are used in flooring applications with substantial mechanical loading, they should also meet the requirements of EN 13813.
