Floor paint construction master's experience sharing

The floor paint has the characteristics of bright, real, beautiful, wear-resistant, waterproof, anti-corrosion, etc. Therefore, not only many floor decoration in public places are floor paint, but also in the home, some people have introduced the floor paint. The construction process, but if it is handled improperly during construction, there will be various problems. What problems will occur in the construction of the floor paint? How to deal with it? We understand that:

1, the floor bleed problem

The bleed refers to a phenomenon in which the undercoat portion is infiltrated into the overcoat film to discolor the overcoat film when a paint of another color is applied to one coating film. The main reasons for the bleed are: 1 the primer is not dry, 2 the color difference between the primer and the topcoat, 3 does not coat the bottom or the substrate contains the color material, and 4 the primer contains the organic pigment.

2, the floor paint surface is more flower problem

It refers to the phenomenon that the surface color of the coating film is uneven, streaks, streaks and hues are disordered. The reason is mainly due to the fact that the construction coating is not fully stirred evenly, the coating is uneven, and the coating components are deteriorated during the construction process.

3, the floor paint surface whitening problem

It refers to the whitening phenomenon of the surface coating after the completion of the construction operation. There are several reasons: the humidity in the air is too high or the temperature is too low, and the water vapor is frosted on the coating film, causing the amine in the curing agent to precipitate. The white mist is concentrated on the surface.

4, the floor paint wrinkles fisheye problem

Wrinkles are caused by wrinkles or irregular lines on the surface of the coating film due to the difference in the drying speed of the inner layer and the surface layer during the drying process of the coating film. The fisheye is a part of the coating film after the coating is applied. The foreign matter present on the surface or mixed with the paint affects the uneven adhesion of the paint to cause shrinkage to expose the surface to be coated; it is a small round or leather-like pore formed by the paint after the coating is evaporated due to the rapid evaporation of the solvent. The phenomenon of such needle-shaped holes

5, the floor paint wrinkles, there are pinhole problems

The surface of the coating film is wrinkled. The main reason is that the drying speed of the inner and outer layers of the paint surface is inconsistent, causing the surface layer to be peeled off. The pinhole is because when the curing agent is mixed with the paint, a large amount of bubbles are generated in the paint due to the stirring, and bubbles are formed during the curing process. Continue to escape, leaving traces on the film to become pinholes.

6, the floor paint ring mountain hole problem

Unevenness of the base surface or insufficient dispersion of the filler will cause the ground to appear as a circular hole like oil. We call it a circular mountain hole. The solution is to carefully inspect the base surface before construction. If there is a problem, it needs to be carefully treated before the epoxy floor paint can be applied. Choose a dispersing filler and strengthen the management of material quality.

7, the floor paint rough, cracking problem

Roughness refers to the appearance of particulate matter with different sizes on the surface layer. The main reason is that the floor coating contains impurities that are not easily dissolved and external dust. The phenomenon of surface cracking is caused by the problems of raw materials and construction quality, which leads to the decrease of the adhesion of the paint layer. Under the influence of external forces, the phenomenon of skin cracking occurs.

8, the floor paint sheds the bottom of the bottom of the problem

Shedding is caused by the fact that the floor cracking loses the original adhesion to the substrate. Under the action of external force, the film is coated into a small part or the whole piece is peeled off from the object surface. The lack of bottom and fullness is mostly the problem of raw materials and the reason of construction. . In short, if you want to do a good job in epoxy floor paint, you must use good materials and use a professional construction team because professionalism is the guarantee of quality.

9, the floor paint curing is too slow

Too slow to cure is that the epoxy resin material becomes slower at a particularly low temperature (10 ° C). At 5 °C, construction is absolutely forbidden. This phenomenon has a great relationship with the viscosity. The lower the temperature, the higher the viscosity, and it will be more difficult to construct. If the curing time is too long, the coating film may be contaminated with dust, sand, etc., and may even slow down the construction period. Another point is that the addition of solvent at the construction site will also cause the curing to be too slow, because the evaporation of the solvent will take away some of the heat and cool the coating.
