floor paint has the characteristics of bright, real, beautiful, wear-resistant, waterproof, anti-corrosion, etc. Therefore, floor paint is used for floor decoration in many public places. However, if it is not handled properly during construction, various problems will occur. How to deal with it? Let’s find out together:
Color bleeding problem
The main reasons for color bleeding are: 1. The primer does not dry, 2. The color difference between the primer and the topcoat, 3. There is no primer or the substrate contains colored substances, 4. The primer contains Organic pigments .
The reason for the problem of stained paint
is mainly caused by insufficient mixing of the construction paint during the construction process, uneven application, and deterioration of the paint components.
There are several reasons for the problem of whitening on the surface
: the humidity in the air is too high or the temperature is too low, and water vapor condenses on the coating film, causing the amine in the curing agent to precipitate, causing white mist to accumulate on the surface.
Wrinkling fish eye problem
Wrinkling is caused by the difference in drying speed between the inner layer and the surface layer during the drying process of the coating film. The surface layer shrinks sharply and shrinks upward, causing wrinkles and unevenness on the surface of the coating film. Or irregular lines and other phenomena; fisheye is a phenomenon in which a part of the coating film shrinks and exposes the coated surface after the coating is applied due to the influence of foreign matter present on the surface of the object to be coated or mixed into the coating; The rapid evaporation of the solvent prevents the paint from being replenished and forms many small circular circles or needle-like pores like the pores of leather.
Problems with wrinkles and pinholes
The main reason is that the inner and outer layers of the paint have inconsistent drying speeds, causing the surface to shrink and peel. The pinholes are because when the curing agent is mixed with the paint, a large number of bubbles are generated in the paint due to stirring. During the curing process The bubbles continue to escape, leaving traces on the coating film and becoming pinholes.
The solution to the crater hole problem
is to carefully check the base surface before construction. If there are any problems, you need to deal with them carefully before applying epoxy floor paint . Choose fillers with good dispersion and strengthen the management of material quality.
The problem of roughness and cracking
is mainly caused by the impurities and external dust contained in the floor coating that are not easily dissolved. The phenomenon of surface cracking is caused by problems with raw materials and construction quality, which lead to a decrease in the adhesion of the paint layer. Under the influence of external forces, peeling and cracking occur.
The problem of falling off and exposing the bottom and poor fullness
The bottom and insufficient fullness are mostly caused by the problem of raw materials and construction. In short, if you want to do a good job with epoxy floor paint, you must choose good materials and use a professional construction team, because professionalism is the guarantee of quality.
cures too slowly.
cures too slowly. It means that the curing reaction of epoxy resin material slows down at a particularly low temperature (10°C). Construction is absolutely prohibited below 5°C. This phenomenon has a lot to do with viscosity. The lower the temperature, the higher the viscosity will be, and it will be more difficult to construct. If the curing time is too long, the coating film will be contaminated with dust, sand and other dirt, which may even delay the construction period. Another point is that adding solvent at the construction site will also cause the curing to be too slow, because the volatilization of the solvent will take away part of the heat and cool the coating film.
