Most general construction workers know that there are three methods of roller coating, brushing, and spraying for the construction of epoxy floor paints, but the advantages, differences, and which method of construction are better for these three methods are very good. Few people can talk about clearing.
Now let's talk about these three construction methods.
Roller coating method Roller coating, also known as roll coating, is a floor coating construction method that uses different types of rollers to apply floor paint to the surface of the floor to achieve decorative effects.
Roller coating is generally divided into three categories: roller coating, artistic roller coating and mechanical roller coating. The most commonly used is roller coating.
Advantages of roller coating: convenient operation, simple construction, time-saving, labor-saving, high labor efficiency, good quality of floor paint coating film formation, no pollution, suitable for large-scale floor construction;
Disadvantages of roller coating: not suitable for finishing on complex objects and advanced decoration.
Brushing is performed with a trowel or a brush, which is completely controlled by hand and experience.
After the floor paint material has fallen to the ground, the inclination of the knife must be controlled by hand. Then use the tool to scrape against the ground. Just start slowly. After you become proficient, you can speed up the scraping.
Advantages of brushing: the paint has a texture, a pattern, and a good appearance; the subsequent curing is convenient.
Disadvantages of brush painting: the construction speed is relatively slow; the effect of large area brush painting is different from the shades and brush patterns in the light groove, and there is a difference in texture.
Spraying is a coating method in which the floor paint is dispersed into uniform and fine mist droplets by means of a spray gun or a dish atomizer, using pressure or centrifugal force, and applied to the surface of the floor.
Spraying can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, eye spraying, and multiple spraying groups.
Advantages of spraying: The spraying operation has high efficiency and is suitable for manual operations and industrial automation production. It has a wide range of applications, including hardware, plastics, furniture, military industry, ships and other fields.
Spraying equipment includes spray gun, paint spraying room, paint supply room, curing furnace / drying furnace, spraying workpiece conveying operation equipment, anti-fog and waste water, and exhaust gas treatment equipment.
Disadvantages of spraying: The main problem of spraying is that highly dispersed paint mist and volatile solvents will pollute the environment and cause harm to human health.
After knowing the three construction methods of floor paint, we can choose the most suitable construction method based on the specific conditions of the floor paint construction.
