Reason analysis and preventive measures of poor color of floor paint and loss of light
The construction team of floor paint often encounters some differences between the color of the project they have completed and the target color.This situation is generally questioned by customers in the acceptance process, causing trouble to the construction team.What is the reason for the impure color of floor paint?What are some ways to prevent this from happening?
Reason analysis and prevention of poor floor paint color
1. In the construction process of floor paint, if the bottom coating film is not completely dry, the construction will continue, which is prone to color mixing and seepage;
2, the floor paint surface paint contains highly soluble solvents, such as esters, ketones;
3. Solvent mixing of floor paint primer and topcoat;
4. Collocation of color shades;
5. It is best to use inorganic pigments for primers, and avoid mixing asphalt and creosote in primers.
The seepage color of floor paint is the phenomenon that the color of floor surface is different.Color infiltration is caused by the color change of the surface coating film when the surface coating of the floor paint is covered with the bottom coating of another color.
Second, the cause analysis and prevention of the loss of floor paint
As we all know, the main composition of floor paint is epoxy resin.In the process of construction, the correct use of additives and environmental factors will have a certain impact on the properties of epoxy resin.Therefore, it is often found that the product loses luster when the floor paint is accepted.When we construct the floor paint, how to ensure that the floor paint does not lose its luster?
1, the construction site humidity is too high (relative humidity is more than 85%), the film of volatile paint is easy to absorb moisture, become white light.
Prevention: the humidity of the construction site should not be too high.
2. In the construction of epoxy floor, too much diluent is used or kerosene and other high boiling diluent is added.
Prevention: diluent dosage should not be too much, avoid adding kerosene and other high boiling point solvents.
3, epoxy floor surface treatment is not clean, containing acid, alkali, oil, wax and water.
Prevention: The surface of the coated object should be thoroughly cleaned before construction.
4. The pigment water content in epoxy floor paint is too high or mixed with water during construction.
Prevention: the water content of the paint should be controlled on the epoxy floor, and water should be avoided during construction.
5, the surface of the coated object is too rough or porous, if not coated with a closed primer, the epoxy floor will lose its luster.
Prevention: the loss of gloss of epoxy floor paint caused by this reason requires our object surface to be closed with primer, filled with putty and polished.
6, the film is completely dry before the rain or dew.
Prevention: The coating should be protected from rain or dew penetration during drying.
7, the film is soft, scratch resistance is not good.
Prevention: according to the use premise of the coated object, choose coating with good weatherability and scratch resistance.
All kinds of problems of floor paint are basically due to materials and construction, so good materials and excellent construction team are the first choice to ensure the quality of floor paint.
