● 1K car paint: The label will be marked as "1K" or "single-component paint", and no curing agent needs to be added. ● 2K car paint: The label will be marked as "2K" or "two-component paint", which needs to be mixed with curing agent in proportion.

The "1K" in 1k automotive paint stands for "one-component", which means that this paint does not require mixing hardeners or other ingredients before use. 1k car paint is a pre-mixed paint that can be used right out of the can, which greatly facilitates construction and application.

The total thickness of the three coats is 375 microns. In this case, the coverage per gallon of paint is approximately 12.3 square meters (37 square meters/3 coats). Therefore, painting a 60,000 square meter ship requires: 60,000 square meters / 12.3 square meters per gallon ≈ 4,878 gallons.

It has the functions of anti-corrosion, anti-fouling and enhancing the smoothness of the hull surface. According to the purpose and construction process, boat bottom paint is usually divided into three layers: primer, intermediate paint and topcoat, and each layer of paint has its unique role.

The initial drying time of epoxy paint is 6-8 hours, and the full curing time is 24 hours; the initial drying time of polyurethane paint is 8-12 hours, and the full curing time is 48 hours; the initial drying time of antifouling paint is 4-6 hours, and the full curing time is 24-48 hours.

The best marine bottom paint should have 6 major properties: 1. Anti-corrosion, 2. Anti-fouling, 3. Adhesion, 4. Abrasion resistance, 5. Environmental protection, 6. Convenient construction ● Easy to paint ● Quick drying ● Strong covering power.

The purpose of painting the bottom of the ship with anticorrosive primer paint is to protect the metal surface of the hull from seawater, electrochemical corrosion and microbial attachment. Seawater contains a large amount of salt and microorganisms, which are extremely corrosive to metal surfaces.

For ships that are docked in freshwater for a long time, antifouling paint needs to be applied to reduce biological attachment. Aluminum and steel hulls are susceptible to corrosion from electrolytes in freshwater. Applying marine bottom paint can provide an additional layer of protection etc..

Generally speaking, the service life of marine bottom paint is about 1 to 5 years, among which the service life of hard antifouling paint is generally about 2 to 3 years. Self-polishing antifouling paint has a longer service life, generally between 3 and 5 years...

Therefore, using $50 per liter of boat bottom paint, paint a 50 square meter medium-sized yacht, apply two coats. It is expected to cost $2516.67, (including: paint cost $416.67, construction cost $1600, cleaning, sanding and inspection cost $500).
