After the application of epoxy floor paint, because of the presence of foreign substances on the surface of the coated or mixed into the paint, such as oil and water, the adhesion of epoxy floor paint is not uniform, resulting in shrinkage, which makes the film unable to cover the next layer of paint surface. This film defect will occur after painting, or after drying. The diameter of shrinkage holes is mostly 0.1-0.2 mm. The existence of particles in the round holes is called fish eye.
Reasons for Fisheye Phenomenon in Epoxy Resin Floor Paint:
1. The selected coatings have high surface tension, poor leveling, high sensitivity to shrinkage, or excessive addition of diluents.
2. During the construction process, the second varnish is applied to the bottom layer of grease varnish without drying thoroughly, resulting in shrinkage or pinholes.
3. Before using the two-component coating, the coating is directly carried out without ripening.
4. The floor paint construction tools, work clothes, gloves, etc. are not clean or the lifting tools and equipment are not clean. The ambient air in the painting place is not clean.
5. The temperature requirement of construction site is too low or humidity is too high compared with that of epoxy floor paint.
Preventive Measures for Fisheye Phenomenon in Epoxy Resin Floor Lacquer:
A. In the development and selection of coatings, attention should be paid to the sensitivity of the coatings to shrinkage.
B. The second construction should be carried out after the bottom grease varnish is fully dried.
C. After the two-component coating is prepared, it needs to be ripened for a period of time before construction can be carried out.
D. Ensure the cleanliness of the epoxy floor painting environment. There should be no dust, grease and mist in the air. No bare hands, dirty gloves and dirty wipes are allowed to contact the surface of the coating.
E. Attention should be paid to the temperature and humidity of the construction site to meet the standard before construction can be carried out.
