As the construction party, the focus is undoubtedly on engineering quality and engineering cost. Currently, many projects use epoxy zinc-rich primer for anti-corrosion, and its cathodic protection can provide good protection to the substrate. So how is the coverage area of epoxy zinc-rich primer calculated per kilogram?
Presumably, friends also know that the paint dosage of a project is calculated based on the area to be painted. Taking epoxy zinc-rich primer as an example, its theoretical dosage is 180g/m2.
However, this value is only a theoretical value. In actual construction, the coverage area of epoxy zinc-rich primer per kilogram is influenced by many factors, and the actual dosage is generally higher than the theoretical value.
Construction method
As we all know, common painting methods include roller coating, brush coating, air spraying, and airless spraying. Different construction methods will affect the average thickness of the paint film. For example, the paint film of airless spraying is more even and smooth, and the paint consumption per square meter is less, naturally reducing the cost.
Skilled workers
Paint construction is not done with just any brush or spray gun. A skilled worker can create a more even and smooth paint film, so the paint consumption per square meter is less than that of a novice.
Substrate polishing level
The smoother and more polished the substrate surface is, the less paint consumption it will have. This is because a rough surface will increase the area to be painted, reduce the adhesion of the paint, and require more epoxy zinc-rich primer to achieve the desired paint film effect.
Coverage area per kilogram = total consumption/coverage area
