Epoxy floor paint requires a higher temperature for the construction environment, and can not be constructed at too low or too high temperature. With the rapid development of modern science and technology, the technology of epoxy floor paint is constantly reformed, and there are many kinds of epoxy floor paint. So how to choose the right epoxy floor paint is very essential for us. Variety selection and coating design basis:
1. Are there any requirements for load, anti-static and anti-erosion in ground use?
2. Base condition (dryness, empty drum, crack, flatness, strength, floor, pollution, etc.).
3. Whether the site environment is suitable for construction.
4. Are there any old coatings on the base surface?
The smoothness of the substrate surface is equal to the degree of concavity and convexity of the surface. In general, we use a 2-meter gauge to measure the gap spacing. It is considered that the smoothness is better below 3 mm.
Ground disposal scheme:
1. The new ground works should be treated by grinding.
2. Degrease and old paint.
3. Long slope fills irregular ground.
4. The ground of supermarket must be dried.
5. Repair damaged area.
The influence of temperature on the construction of epoxy floor paint:
In epoxy floor coatings, it is difficult for two-component coatings to cure at temperatures below 5 degrees, or the reaction is very slow, resulting in a significant extension of the film-forming time, or lead to the failure of film-forming and curing.
Not only that, dust and other debris easily contaminate its surface, resulting in poor decorative effect. At the same time, it will also affect the function of the film, make its hardness lower, wear resistance worse and so on, thus directly affecting the service life of the floor.
The influence of humidity on the construction of epoxy floor paint:
According to the requirements of epoxy floor paint construction, when the relative humidity of air is higher than 85%, it is impossible to carry out the construction of epoxy floor paint, because of the defects such as whitening and cracking easily.
The Engineering Center thought that the construction of epoxy floor paint under the condition of excessive humidity index would cause dew on the surface of the coating. The condensed water would damage the curing agent and cause the phenomena of whitening, losing gloss, sticking and sticking back of the coating, thus greatly reducing the decorative effect of the surface.
