What are the Types of Construction Fireproof Coating?

Various types of construction fireproof coating are available for different applications. These include spray-applied fire resistant materials, fireproof paint and intumescent coatings.
The choice of coating is influenced by several factors. These include the substrate, film thickness and end use requirements. It is also important to consider the load-bearing capacity and integrity of the material.

Spray-applied fire-resistive materials can be applied wet or dry. They can also be applied to achieve a high aesthetic finish. Aesthetic finishes require more care, so it is important to specify what you need in the specification.

Intumescent coatings are used in steel and other exposed surfaces to protect the steel. When exposed to extreme heat, they expand and form a thick layer of insulation. They also release a flame damping gas. This creates a buffer zone between the steel and fire.
These coatings are designed to withstand temperatures from 350c to 650c. They can be used for concrete, steel, wood and other materials. They are applied by roller or spray. A typical expansion ratio is around 50:1.

These coatings are available in a variety of solvent-based or water-based solutions. Solvent-based coatings tend to cover wider sections than water-based materials. They can be used to protect smaller sections, but may not provide as much corrosion protection.
Fireproof paint is used in office buildings, parking garages and governmental buildings. The cost of fireproof paint depends on the amount of coating needed. It can also be calculated by the required fire resistance.
