Brandskyddsmålning

Brandskyddsmålning, also known as intumescent or fire-retardant painting, is a specialized coating application designed to protect building structures from fire. When exposed to heat, these paints undergo a chemical reaction, swelling up to form a thick, insulating char layer. This char layer acts as a barrier, slowing down the transfer of heat to the underlying structural material, such as steel or wood.

The primary purpose of brandskyddsmålning is to extend the fire resistance time of a building element. By delaying the structural collapse or degradation caused by fire, it provides occupants with more time to evacuate safely and allows firefighters more time to control the blaze. This is crucial for maintaining the structural integrity of a building during a fire incident.

The effectiveness of brandskyddsmålning is dependent on several factors, including the type of paint used, the thickness of the applied coating, and the specific fire resistance rating required for the structural element. Different paints are formulated to achieve varying levels of fire protection, measured in minutes (e.g., 30, 60, 90, or 120 minutes). Professional application is essential to ensure the correct film thickness and uniform coverage, which are critical for achieving the desired fire performance. Regular inspection and maintenance may also be necessary to confirm the coating's integrity over time. This type of painting is a vital component of passive fire protection strategies in many modern construction projects.
