The strength of C1 tile adhesive can vary depending on the manufacturer and the specific product. However, as a general rule, C1 tile adhesive has a tensile adhesion strength of at least 1 N/mm² when tested in accordance with European Standard EN 12004.

Tensile adhesion strength is a measure of the force required to pull a tile away from the substrate to which it has been fixed. A higher tensile adhesion strength indicates a stronger bond between the tile and the substrate.

C1 tile adhesive is designed for use in low-stress areas where there is minimal exposure to moisture or temperature fluctuations. It is typically used to fix ceramic tiles on internal walls and floors in areas such as bedrooms, living rooms, and hallways.

While C1 tile adhesive has sufficient strength to hold tiles in place in these types of applications, it may not be suitable for more demanding installations. For example, if tiles are exposed to heavy loads or significant moisture, a higher-strength adhesive such as C2 or C2S1 may be required.

C1 tile adhesive has a tensile adhesion strength of at least 1 N/mm² and is suitable for use in low-stress areas where there is minimal exposure to moisture or temperature fluctuations. For more demanding applications, a higher-strength adhesive may be required. It is important to choose the right type of adhesive for the specific tile and substrate being used to ensure a successful installation.
