Friends who have used fireproof coating may encounter bubbles after brushing fireproof coating powder, but they do not know what is going on. Next, we will analyze why there are bubbles after painting fireproof coating

Why do fireproof coating manufacturers have bubbles after painting 

1. The dilution agent used is mixed with water, and now most of the low-quality fireproof coatings on the market are adulterated with water and mixed into the coating. Due to the density of fireproof coatings being higher than water, after brushing, the water will be washed away by buoyancy to form small bubbles on the surface of the coating. After drying, small circular pits will appear like the surface of the moon, which is commonly known as pockmarks.  

2. After the fireproof coating is painted, the substrate leaks water, causing problems with the fireproof coating film and the appearance of bubbles.  

3. After the fireproof coating is applied, the coating applied is too thick, causing the previous coat of fireproof coating to not dry and resulting in bubbles.  

4. The mixture of two fire-resistant coatings caused a chemical reaction, resulting in the formation of bubbles,.   

5. The surface of the base layer has not been properly treated, resulting in a appearance similar to bubbles in the coating.  

So, when choosing fire-resistant coatings, it is not only necessary to choose high-quality fire-resistant coatings like Eunsis, but also to understand some knowledge about construction (for details, please refer to the "Application and Brushing Methods of Indoor and Outdoor Steel Structure Fireproof Coatings")

When choosing a fireproof coating manufacturer, people may also learn about fireproof paint. Some people may have doubts about what fireproof paint is, and fireproof paint can also be used as fireproof coating. What is the difference between fireproof paint and fireproof coating.  

What is the difference between fireproof coating and fireproof paint

In fact, fireproof coatings can be divided into powder fireproof coatings, water-based fireproof coatings, and oil-based fireproof coatings according to solvent types. Fireproof paint is an oil-based fireproof coating that uses organic substances such as gasoline as solvents, also known as fireproof paint or oil-based fireproof coating, and belongs to a type of fireproof coating. (For details, please refer to the "Types of Fireproof Coatings")

Simply put, fire-resistant paint is a type of fire-resistant coating, which is an oil-based fire-resistant coating. The difference between fire-resistant paint and fire-resistant coating is the relationship between inclusion and being included. And fireproof coatings not only include fireproof paint, but also water-based fireproof coatings and powder fireproof coatings.  

So, fireproof coatings include oil-based fireproof coatings and water-based fireproof coatings, and fireproof paint is exactly oil-based fireproof coating. When choosing, everyone must keep their eyes open and make purchases according to different working conditions and needs. (For details, please refer to "What are the types of fireproof coatings and which buildings are suitable for"), otherwise buying the wrong one is not worth the loss.
