1. The construction environment and the drying process of the epoxy floor paint film are not clean and dusty, which makes the dust fall on the film which is still in the leveling stage, and eventually causes the dust to adhere to the floor paint film and make the film rough. 2. The epoxy floor coatings were not filtered before painting, and were mixed with mechanical impurities. These mechanical impurities were coated on the coatings together with the coatings. When the coatings were dried, the mechanical impurities were highlighted on the floor coatings, which eventually led to the appearance of rough coatings. 3. Because epoxy floor coatings are two-component or multi-component coatings, and belong to chemical curing coatings, when the coatings are mixed with curing agents, the coatings begin to play a chemical role, and the viscosity of epoxy floor coatings increases slowly. After a certain time, the coatings begin to gelatinize and then solidify directly into films. When the coating begins to gelatinize and continues to be applied, the film of floor paint may be rough.
Fourth, the construction site temperature is too high, the diluent volatilizes too fast, the epoxy floor paint coated on the coating has no leveling time has begun to solidify, so there will be rough phenomenon.
Neglected links in epoxy floor construction
Epoxy resin floor can not only protect concrete floor, but also improve the anti-wear, anti-weight and anti-compression performance of the floor surface. It can also achieve the effect of beautiful decoration and clean dust-free workshop.
The thickness of epoxy resin floor is very thin. It bears all the heavy pressure on the surface. It is mainly supported by the base of the floor. The quality of the base of the floor is the focus of the quality of the epoxy resin floor.
The quality of the base surface is often a problem that many people do not pay attention to, and even often there is a hidden quality hazard caused by neglecting the treatment of the base surface of floor paint.
Following are several reasons for the hidden danger of engineering quality caused by neglecting the treatment of ground surface:
1. Party A. Party A considers that since the concrete floor is finished and epoxy floor paint is applied on it, the concrete floor need not pay too much attention to quality, which is almost indifferent.
2. Floor foundation construction team. The construction team believes that the ground surface will be covered with epoxy floor paint after treatment anyway. Party A can't see any minor problems, just do it anyway.
3. Construction side of epoxy floor paint. The Construction Party of epoxy floor paint does not know enough about the base surface, and does not express the requirements for the base surface in communication with Party A, nor does it pay attention to the construction. Or peer competition is serious, no matter how poor the foundation of the floor is, do a good job of collecting money and leaving. As a result, people's awareness of the importance of fundamentals is becoming weaker and weaker.
As a professional floor paint manufacturer, poor treatment of concrete base will lead to the decline of the quality and service life of epoxy floor paint, increase the probability of floor paint defects, and Party A will need frequent repairs in the process of using epoxy floor paint. Continuously affect the use of experience, and affect production. For the concrete ground construction team, the ultimate retrospective responsibility, or to find the construction side of the concrete foundation, is still the ultimate responsibility. For floor paint builders, frequent repairs, consumption of human energy, and continuous increase in costs, will become a huge burden.
Therefore, the quality of concrete base surface and the quality of epoxy coating construction are the key points in the epoxy floor coating project. Whatever link is wrong, the quality of the finished project will be greatly reduced.
Therefore, the floor paint construction party must pay attention to the treatment of concrete base.
