What types of projects can fireproofing paint be applied to?

Fireproofing paint is widely applied in many works and architecture. So what are the properties of fireproof paint? What is the application and process of this paint? The content below will answer the above questions.

Overview of fireproofing paint: Composition, application and implementation process

First, we will talk about the composition and how it works. Next, the article will introduce the application of this paint. Finally, the process of implementing fireproofing paint.

1. What are the components of fireproofing paint? How to know

Flame fireproofing paint is an active coating that swells when exposed to high temperatures, thereby increasing the volume of the protective layer and reducing the density of contact between the flame and the structure. This type of paint consists of many chemicals, all suspended in a binder. The adhesive softens when exposed to heat, allowing the suspended chemicals to react. Specifically, the paint reacts to heat by expanding in a controlled manner many times over its original thickness. The paint then creates carbonaceous deposits in the form of bubbles, which act as insulation to protect the surface.

2. Fire fireproofing paint can be applied in which works?

Paint can be applied outside and inside the building. Applying fireproofing coatings off site can enhance fire protection systems.

In many cases, an additional coat of primer may be required prior to the application of flame retardant paint. In this way, after finishing, the coating will be smooth and flat. Flame retardant coatings can be improved by adding a topcoat.

Paint can be used to protect concrete, wood, steel or aluminum construction. Each type of material will have the necessary thickness to match a certain fire resistance time. A qualified technician will thickness based on the critical temperature of the layers of the material.

3. What are the requirements for the implementation of fireproofing coating?

The fireproofing coating process begins with an anti-corrosion primer and ends with a color coating. These two layers ensure good adhesion and anti-corrosion performance. Three common surface treatments are: High pressure water blasting, wet sandblasting and dry sandblasting.

• Step 1: Clean the surface

Before applying a compatible primer, the surface of the material must be treated and cleaned, free of grease, rust, dirt. After cleaning, the surface must be sanded and meet Swedish Standard SA 2.5.

• Step 2: Apply primer

Compatible primers are:

Acrylic

Short or medium alkyd oil

Two-component epoxy

Zinc-rich epoxy (contains about 80% by weight of metallic zinc powder)

Zinc-rich epoxy (contains approximately 96% by weight of metallic zinc powder)

Zinc silicate

Polybutadiene (Promat® TY ROX).

• Step 3: Prepare tools and equipment for fireproof paint

To achieve speed and quality of finish, air-absorbent coatings are best applied with powder coating equipment, brush and roller may also be used.

• Step 4: Apply a layer of fireproof paint

Use a spray nozzle to apply fireproof paint to finish, the paint must be dry and reach the standard thickness, then move to step 4.

• Step 5: Apply color coating

Flame fireproofing paint does not have eye-catching and diverse colors. Therefore, after applying the fireproof layer, the construction team will apply an additional layer of color paint to increase the aesthetics of the project. When the paint is completely dry, a shiny, smooth and flat surface is standard. The painting process needs to be carried out by highly qualified technicians, closely monitored and evaluated.

Hope the article has helped you understand more about the application of fireproofing paint. This type of paint has many advantages, but to get the most out of it, the paint application process must be performed by a skilled and professional person.
