Although there are many benefits to using primer, in some cases you can choose not to use primer and directly spray white traffic paint. For example: construction time is tight, the road condition is good, and you can choose not to use primer in these cases for short-term use.

Main types of steel anti-corrosion coatings： 1. Epoxy anti-corrosion coatings 2. Polyurethane anti-corrosion coatings 3. Zinc-rich anti-corrosion coatings 4. Inorganic zinc silicate coatings 5. Asphalt-based anti-corrosion coatings 6. Polyurea anti-corrosion coatings 7. Acrylic anti-corrosion coatings

In theory, it is feasible to spray 2K car paint on 1K car paint. 2K paint has strong adhesion and can cover 1K paint to form a strong paint film. Before spraying 2K paint, make sure that the 1K paint has been completely cured, otherwise it may cause the paint film to be unstable or fall off.

Epoxy zinc-rich primer: The zinc content is usually between 65% and 85%. Epoxy zinc-rich primer has excellent adhesion and chemical resistance, and is suitable for metal protection in industrial and marine environments.

2K car paint is widely used in the field of car painting due to its excellent performance. Its service life is generally between 5 and 10 years, and the specific time depends on many factors. Environmental factors, usage habits and construction quality will affect the life of 2K car paint.

Concrete is a porous material with high water absorption. This means that when the paint is directly applied to its surface, it is easily absorbed by the concrete, resulting in uneven distribution of the paint and affecting the overall effect.

Anti-corrosion coating is a type of coating specially used to protect the surface of materials from corrosion. It is mainly used for the protection of materials such as metals, concrete, and wood. Epoxy anti-corrosion coatings are anti-corrosion coatings made of epoxy resin as the main film-forming substance, with excellent mechanical properties, adhesion and chemical stability.

The main uses of white marking paint: 1. Road traffic markings: ● Lane dividers ● No parking lines and parking spaces ● Pedestrian crossing lines 2. Parking lot and warehouse markings: ● Parking lot markings ● Warehouse markings 3. Stadium landmarks: ● Stadium markings ● Playground markings 4. Industrial and commercial uses: ● Workshop and factory markings ● Airport markings 5. Other uses: ● Parking lot and garage markings ● Construction site markings.

Acrylic paints can maintain the stability and color brightness of the coating in both hot and cold weather. Epoxy floor coatings are relatively weak and may yellow and age after long-term exposure to sunlight, so they are more suitable for indoor or protected environments.

In some application scenarios that require both anti-corrosion performance and adhesion, you can consider using the two primers in combination. For example, a metal etch primer can be applied first to improve adhesion and then an epoxy primer can be applied to provide long-term corrosion protection.
