Best 6 Intumescent Paints

Intumescent paint is a coating that swells in a way that thickens the coat many times when exposed to heat, producing a large number of small bubbles to create an insulating layer to protect the building’s structure.

Intumescent paints are designed to prevent the spread of flames for about 30-120 minutes. Few paints can exceed this time limit. This type of paint is similar in appearance to regular paints. The only difference is that an intumescent paint’s qualities provide additional security to the building. For example,

1. Reducing materials’ flammability.

2. Reducing smoke emissions.

3. Reducing fire intensity.

4. Reducing the spread of fire.

• How intumescent paints work?

Intumescent paints interact with extreme temperatures and create a thick and flame-retardant coat to insulate the structure with paint that swells when exposed to fire. This gives people an extra 30-120 minutes to stop the fire before it reaches the surface and give people time to escape fire unharmed. For this very reason, intumescent paint is important for cutting human and material losses.

The use of intumescent paints on walls and ceilings is one of the most effective ways to prevent the spread of flames and increase the level of safety for your building. Intumescent paints vary in types depending on the surface. There are suitable kinds of intumescent paints for each type of surface such as: wood, walls, ceilings, metals, electrical cables, fences, concrete, and plastics.

How intumescent paints work?

• The difference between intumescent paints and flame retardant

Although they have one fundamental difference, intumescent paints and flame retardant paints are similar in their effectiveness to prevent the spread of fire. The difference is that flame retardant paints are not naturally resistant. They are chemically treated to put out small-scale fires and slow the spread of flames.

As for intumescent paints, they are by chemical composition resistant to fire and extreme heat. These paints work by placing a coat between fire and any material underneath. During the fire, the intumescent paint responds to the flame by forming bubbles, swells, and a non-combustible foamy coat. This coat is what keeps the building protected for longer times. 

Experts often recommend applying intumescent and flame retardant paints in houses, emergency exits, and apartments. There are also some paints that combine the two types such as Firewood 150 paint for wooden surfaces.
