What is fireproofing epoxy paint? Common mistakes when applying fireproof paint

Finding the right fireproofing solution is something that bothers investors. Fireproof epoxy paint is not only explosion-proof but also has good impact resistance, limiting corrosion. Below is information about the line of fireproof paint.

Fireproofing epoxy paint: Concept, importance, construction process and how to fix errors

The fireproofing coating will help limit the damage to property and people in the event of a fire or explosion. Today's article will introduce the concept and importance of this paint. Then will summarize the construction process and finally the common mistakes in the process of fireproof epoxy coating.

What is fireproofing epoxy paint? The importance of using fireproofing paint

Flame retardant paint is an economical and highly appreciated method of fire prevention today. The type of paint has a composition of acrylic compounds, rice husks, epoxy and chemical additives with fire-retardant properties. Fireproofing epoxy paint is suitable for many materials, especially steel and aluminum structures.

The epoxy coating acts as a protective barrier to help the building structure from the harsh effects of the environment. The paint layer is also resistant to high temperatures to help limit fire and collapse. According to experiments, explosion-proof epoxy paint helps to slow down the fire so that the fire department can promptly handle it.

Explosion-proof paint works by temperature sensing mechanism. When the temperature is abnormally high, the paint layer will automatically increase in thickness and swell many times to prevent the flame heat from contacting the surface of the material. Besides, the paint will produce non-flammable and non-toxic air bubbles.

Main features of fireproof epoxy paint:

• Reducing the possibility of catching fire on building materials and structures.

•  Make sure the frame remains stable within 2-3 hours of the fire.

• Flame retardant paint can slow down the burning process and the speed of fire spread.

• Fireproof paint can be applied on many surfaces such as metal, wood, painted surface... This paint is suitable for indoor and outdoor use.

• These painting equipment are quite diverse: electrostatic sprayer, brush or roller...

• Effective and safe fireproof epoxy coating construction process

The process of coating fireproof paint consists of 4 basic steps:

Step 1: Treat the surface of the material to remove dirt, dust, grease. The processing step helps to create roughness and grip for better adhesion of the paint.

Step 2: Start applying primer to create an intermediate connection between the surface of the material and the top paint. This coating has an ideal thickness of about 50 µm - 80 µm. Make sure the primer is completely dry before starting to apply the flame retardant paint.

Step 3: Apply fireproofing epoxy coating: the thickness of the paint layer depends on the purpose of use and the need for fire protection. The time it takes for the paint to completely dry also depends on factors such as temperature, thickness, type of paint, etc. Therefore, this stage should be done by an expert.

Step 4: Apply color coating after the explosion-proof paint has completely dried.

Errors when applying fireproofing epoxy paint and how to fix them quickly

During the construction process, some errors will occur in fireproofing paint. Most errors are fixable. Here are the reasons why the fireproof epoxy coating does not work.

• Paint film melted

This error occurs because the paint mixing step does not meet the manufacturer's requirements for speed and time. Another cause is that the paint is diluted because of the high amount of solvent. Poor technician skills are also the cause of the paint film flowing, uneven color.

• Paint film with air bubbles

The cause of the bubble in fireproof epoxy paint is that the paint film is too thick, the solvent cannot be released during the evaporation process.

• Paint film is wrinkled

A primer that does not set standards will cause the fireproof coating to be crumpled during application.

How to fix: Read the instructions for use and mix paint according to the ratio recommended by the manufacturer. Mix paint with reasonable time and speed. Clean the surface with an effervescent knife or sandpaper and seal with flame-retardant epoxy paint. Choose a construction technician with high skills and experience.

Above is information about fireproofing epoxy paint. This type of paint is applied in many large projects because of its outstanding features. In addition to using paint, buildings can also apply other fire protection methods to ensure safety and limit damage.
