How many square meters can one kilogram of paint cover?

The question should be phrased like this: My facility’s pipes and frames require anti-corrosion treatment. What are the specific requirements for this anti-corrosion protection? For example, how many years are the pipes supposed to last? What environment the pipeline is in, such as whether it contains high-temperature media or normal-temperature media. Is it above ground or buried? That’s about it; those who specialize in anti-corrosion coatings will provide you with a good plan, as well as an approximate amount needed and a quote. Here is a simple anti-corrosion solution for you: 1 layer of epoxy iron oxide primer, or 2 layers of epoxy limonite primer; the dry film thickness should be 80 microns. The theoretical usage rate is 4 square meters per kilogram, but in practice it may range from 2 to 3 square meters per kilogram. Brush coating is very material-saving. 2 coats of acrylic topcoat; dry film thickness of 70 microns. Color is adjustable and determined by the customer. The theoretical usage is 5.5 square meters per kilogram, while the actual usage may range from 3 to 4.5 square meters per kilogram. In a normal corrosion environment, after grinding and painting, this system should hold up for about 3 years without problems. Here is a table showing the usage specifications for our company’s products, based primarily on a dry film thickness of 40 microns.

Thank you, I was also looking for something in this area

You are asking about the usual anti-corrosion methods used on the ground, namely manual and electric rust removal; the amount of primer required is 0.3 kilograms per square meter, while that for the topcoat is 0.2 kilograms per square meter.
