Sometimes we can see a tear-like mark on some epoxy floors under construction, which is called "flow mark". It is a trace formed by the downward flow of paint film caused by various factors during the spraying process of epoxy floor paint. How do we deal with the stains that affect the beauty of floor paint? Epoxy flooring was originally used for functional flooring: such as anti-corrosion, wear-resistant, anti-skid, developed to general industrial flooring; besides functional requirements, it also has decorative effect. On the basis of extensive application of industrial floor, with the continuous improvement of people's living standards, it has been widely used in family decoration. Epoxy floor is a kind of high-strength, wear-resistant and beautiful floor. It has the advantages of seamless, solid texture, good resistance, anti-corrosion, waterproof, dust-proof, convenient maintenance and low maintenance cost. But the epoxy flooring will also "cry", haven't you heard, what is the specific situation? Today Xiaobian will introduce it to you.
Reasons for flow marks:
1 Environmental issues
The construction environment is not very good, the temperature is not suitable, too low or too high; the content of solvent vapor in the construction environment is too high; and the air circulation in the construction site is poor.
2. Construction problems
During construction, improper operation resulted in the formation of flow marks in the spraying of epoxy floor paint. The spraying gun is too close to the ground or too slow when moving the spraying gun, which results in too thick spraying at one time.
Spray gun is also a key factor to determine the quality of the floor, so the use of spray gun should be appropriate, for example, spray nozzles with large amount of paint should be equipped with air holes with high air volume. Similarly, when the spraying range becomes smaller, the nozzle with less paint should be replaced.
3 Material issues
If the epoxy floor paint does not match the required diluent, or if excessive moisture-proof agent is added, the flow marks will be formed if the adhesion of the material is too low.
Methods of preventing flow marks:
In the spraying process of epoxy floor paint, the second spraying can only be carried out after the first coating is completely dry.
The diluent selected by the pre-construction inspection should be matched with epoxy floor paint, and other additives should be added in proper proportion, not excessive or small amount. Check the construction tools to ensure their normal functions.
Before spraying, make sure the spraying ground is thoroughly cleaned, and if it is more lubricated, the paint surface should be polished beforehand.
In the process of floor construction, we must control every link, otherwise we will have to find ways to remedy problems, which is also a rhythm of spending money.~
Epoxy flooring can only withstand 80 degrees of temperature. It is necessary to lay steel plates or other high-temperature isolation pads on the ground for welding or oxygen cutting.
The surface of epoxy floor is easy to clean, and it is usually scrubbed with water. If you encounter dirt that is difficult to clean, you can use industrial degreaser, descaling agent, etc. Then rinse with water. For fairly stubborn stains, mechanical cleaning can also be used, but do not apply pressure on the ground, too much wear and tear to affect the smooth and luster of the ground.
