Let's discuss the key points regarding epoxy maintenance.

Reason: The substrate surface was not properly prepared before applying the epoxy floor coating, as it still contained oil stains, wax, moisture, dust, and chemicals. Alternatively, the interval between surface pre-treatment and the actual painting process was too long.

Handling: The surface of the object to be coated should be cleaned thoroughly before painting, and coating work should be carried out immediately afterward.

2. Reason: Improper selection of primer. For instance, if the primer is too rigid, it can cause the topcoat and primer to lose their necessary adhesion.

Treatment: A primer with excellent adhesion and wettability should be selected.

3. Reason: The surface of the object being coated is too smooth.

Treatment: The surface of the object to be coated should be sanded or chemically treated. Existing paint layers should be re-sanded before treatment.

4. Reason: Applying topcoat or clear coat before the primer has fully dried can easily cause cracking or peeling of the coating film.

Handling: Generally, the topcoat should be applied only after the primer has completely dried.

5. Reason: The coating film is too thick. Since the surface layer has already dried thoroughly, while the underlying layer dries more slowly or remains uncured, excessive shrinkage of the topcoat during the drying process leads to cracking and subsequent flaking.

Handling: During construction, care should be taken to ensure that the film thickness of each coat of paint is not too thick.
