What is the reason for the falling off of the paint on the floor of the parking lot?Disposal after shedding
Any kind of product will age, the floor coating is no exception, if the scientific maintenance, will make the product more durable.
The use of epoxy floor paint technology in parking lots is relatively common, mainly because the use of epoxy floor paint can save time, the ground can not be dusty, easy to clean, etc., not only can be used in underground garages, but also can be used in large places such as factories and workshops.Next, what are the reasons for the falling off of the floor paint in the parking lot?
1. Improper treatment at the grassroots level
The ground will appear impurities, such as oil, water solubles, rust and other not thoroughly cleaned, the construction environment is not clean will cause the phenomenon of falling off.Or the smoothness of the base surface is too high, and there is no targeted treatment before construction.Additional, the time that besmear again between coating layer is too long, when construction, interval time is too long, cause the impurity such as dust adheres to the surface of the ground.
2. The film is too thick
Because the top layer is completely dry, but the bottom layer is not fully dry, it is easy to overshrink the finish coat during the drying process, causing the surface to crack or fall off.
The water content of the base is too high. If the water content is too high, the ground construction will make the epoxy floor paint layer off the ground, and the water content is low, and the cohesiveness will be better.
3. The base is too loose
If it is loose on the ground, the loose layer must be removed before construction, otherwise, the epoxy floor paint coating will fall off together with the loose concrete layer.However, the problem of the material itself will also cause shedding, therefore, in the construction, we must pay attention to the relevant details, in strict accordance with the construction requirements to operate, so as to avoid many problems.
How should be done after appearing to fall off phenomenon?
If the parking lot floor paint is damaged, it must be repaired in time with paint. Do not let the oil penetrate into the cement, causing a large area of paint to fall off. If necessary, it can also be waxed.
