Heavy duty anti-corrosion paint is a common coating widely used in the anti-corrosion protection of industrial equipment, large structures, and steel structures. This article will provide a detailed introduction to the key points of the construction process of heavy-duty anti-corrosion paint, so that you can learn how to apply it quickly.

1、 Primer

1. Concept of primer: Primer is the first layer of heavy-duty anti-corrosion paint, mainly used for anti-corrosion, enhancing adhesion, and improving paint film quality.

2. Construction method: For the construction of primer, it should be strictly carried out in accordance with the coating standards. Generally speaking, the primer needs to be brushed or sprayed onto the surface, and bottled paint needs to be thoroughly stirred before use to achieve the corresponding consistency and uniformity.

3. Coating requirements: Primer coating must ensure uniform coating film and appropriate thickness; The construction temperature should be between 5 and 40 ℃, and the relative humidity should not exceed 80%.

2、 Intermediate layer

1. Concept of intermediate layer: The intermediate layer is the second layer in heavy-duty anti-corrosion paint, which can enhance corrosion resistance, wear resistance, and hardness.

2. Construction method: The intermediate layer can be sprayed, brushed, or rolled, and the corresponding operation method can be selected according to the actual situation. Note that there are significant differences in the intermediate layer paint materials provided by different manufacturers, and construction should be carried out in conjunction with the corresponding construction instructions.

3. Painting requirements: Before painting, the surface oil stains and rust should be fully removed to ensure the adhesion of the intermediate layer paint film. Each layer of coating must be completely dry before proceeding with the next construction operation.

3、 Topcoat

1. Concept of topcoat: Topcoat is the third layer of heavy-duty anti-corrosion paint, mainly used to enhance the appearance effect and anti-corrosion durability.

2. Construction method: The construction method of the topcoat is similar to that of the intermediate layer, and multiple methods can be used. The corresponding method can be selected according to the actual situation.

3. Coating requirements: Before applying the topcoat, the surface should be carefully cleaned to remove impurities and ensure a flat and dry surface. Avoid construction in low temperature or high humidity environments, and control the consistency of the paint to avoid excessive sagging and brush marks on the paint film.

The above are the core points of the detailed explanation of the construction process of heavy-duty anti-corrosion paint. I hope it can provide some help to everyone and complete the work more easily and efficiently in daily construction operations.
