Fire-resistant coatings for concrete slow down the temperature increase in concrete and reinforcement and can be used when additional structural fire protection is required.
HENSOTHERM® 820 KS is described as an intumescent coating that forms a thermal insulating protective layer in the event of a fire.
In renovation projects or existing structures, additional concrete fire protection may be necessary. When the existing structure does not meet the desired fire protection requirements, fire-resistant coatings can provide a suitable solution.
Fire-Tech Solutions assists in selecting systems that slow down the temperature increase in concrete and reinforcement. This ensures that the structural stability remains intact during a fire.
This solution is often used when structural modifications are undesirable or when space saving is important.
Frequently asked questions
Why might concrete need additional fire protection?
In existing or to be renovated structures, the existing concrete cover may not be sufficient for the desired fire protection.
Does a fire-resistant coating make concrete stronger?
No. The coating does not increase the normal structural strength. The function is to slow down the temperature rise during a fire.
Can the coating be applied to ceilings and columns?
Depending on the system, application to horizontal and vertical concrete surfaces may be possible.
Does the substrate need to be prepared?
Yes. The substrate must be clean, load-bearing and suitable for the chosen system.
How is the required layer thickness determined?
The required layer thickness depends on the desired fire protection, concrete quality, coverage, reinforcement, and system documentation.
