Intumescent Coating NYC

What Is Intumescent Coating?

Intumescent paint or intumescent coating is used for structural fire protection in buildings. It is one of the most effective ways of making sure your building structure does not collapse in the event of a fire hazard. The intumescent coating is applied to the building’s structural elements to achieve passive fire protection so that the columns, beams, floors, and roofs do not collapse and allow safe evacuation.

When exposed to high temperatures, it expands to many times its original wet film thickness and provides insulation for the substrate by reducing the conduction of heat. Intumescent paint is also known as fire-retardant paint because it slows the spread of fire.

Is Intumescent Paint Fire Resistant?

Intumescent paint swells when exposed to heat resulting in a form of thick insulating char of small bubbles that act as a layer of insulation for the substrate. The intumescent coating reacts to high temperatures and loses density as it expands. The foam or char that is created as a result of the chemical expansion offers structural fire protection preventing industrial and commercial buildings from collapsing.

Areas Where You Can Apply Intumescent Coating?

The intumescent coating can be applied in industrial and commercial buildings for passive fire protection. Steel, timber, and concrete can be coated with intumescent paint to make them fire-resistant. You can get intumescent paint in houses, offices, malls, salons, gyms, restaurants, hospitals, factories, and hotels.

Is the Finish of Intumescent Coating Smooth?

How smooth the finishing of intumescent coating is, depends on the type of intumescent coating you opt for. This is also directly related to the cost of the intumescent coating you choose. The cost of the paint depends upon the

The finish of the intumescent coating is not perfectly smooth but has a bit of texture. If you prefer a smooth finish, you can ask your fireproofing contractor for a smooth finish on the intumescent coating beforehand. The contractor will sand the coating before applying the decorative coating on top of the intumescent paint.

Is Intumescent Paint Better than Cementitious Paint?

The cementitious coating is cement-based and is often used in buildings for waterproofing and fireproofing. It can sustain high temperatures and provide passive fire protection. However, since it is lightweight, a layer of moisture can develop between the substrate and coating. This leads to corrosion and low durability. On the other hand, intumescent paint offers high durability and does not corrode easily.

Why Choose Air Seal Insulation Systems for Intumescent Coating?

Air Seal Insulation Systems provides top-quality intumescent coating solutions for your industrial and commercial properties to help you and your customers remain safe in a fire hazard. We value our customers’ safety and satisfaction above all and provide certified and tested fireproofing solutions for structural fire protection. Our experienced contractors are skilled at the art of applying intumescent paint to your steel, timber, or concrete structures according to your requirements.


Intumescent paint is one of the most effective and lightweight passive fire protection options that can be used in modern buildings. It swells up to 100 times its thickness under heat exposure to form a char that protects the substrate from fire. It slows down the progress of fire giving time for the safe evacuation of people from the building.

The application of intumescent paint is most popular in industrial and commercial buildings but it can be applied in residential properties as well. It can be used to fireproof timber, wood, concrete, and steel structures.

Intumescent coating is mostly used for life-saving protection in steel and concrete buildings. Due to its high fire rating, it can be used in the protection of timber and wood as well.

Not only does an intumescent coating provide high levels of fire protection, but it also has high durability. You will not have to worry about the paint cracking or chipping off with an intumescent coating.

Intumescent coating when applied by an experienced fireproofing contractor is not hazardous to health. If you want to have peace of mind when going for an intumescent coating, make sure to get top coating as an add-on to protect yourself from any harmful toxins that might be released in a fire hazard.

Steel tends to rust and corrode easily. High-quality intumescent paint when applied with two-pack epoxy primers offer corrosion protection for steel structures.

In general situations, top coating for intumescent paint is not required. However, if you are in a high-humidity area, then the top coating is suitable to achieve maximum fire protection and durability from the intumescent coating.
