The latest promotion plan for China Coatings Online has been released, featuring a comprehensive overview of floor paint construction.
With the rapid development of China's economy and construction industry, the demand for floor paint has been continuously increasing, leading to a prosperous development period for floor paint. Floor paint features brightness, authenticity, beauty, wear resistance, waterproofing, and corrosion resistance, making it widely applicable in workshops, parking lots, sports fields, and other places. However, improper handling during construction can lead to various issues. Meitu's engineering paint will review the various issues that arise during the construction of floor paint with you.
1. Floor Color Penetration Issues
Color penetration refers to the phenomenon where a different color of paint is applied over a coating, causing some of the underlying layer to seep into the top layer and change its color. The main reasons for color penetration are: the primer is not dry, color difference between the primer and topcoat, no primer applied, or the substrate contains colored substances, or the primer contains organic pigments.
2. Floor Paint Surface Blooming Issues
This refers to the uneven color on the surface of the coating, showing spots, stripes, and color confusion. The main reason is that during the construction process, the coating was not mixed thoroughly, applied unevenly, or the components of the coating have deteriorated.
3. Floor Paint Surface Whitening Issues
This refers to the whitening phenomenon of the coating after the construction work is completed. The reasons include: high humidity or low temperature in the air, moisture frosting on the coating, amines separating from the curing agent, resulting in white mist accumulating on the surface.
4. Floor Paint Wrinkling and Fish Eye Issues
Wrinkling occurs during the drying process of the coating due to the difference in drying speed between the inner and outer layers, causing the surface to shrink and form wrinkles or irregular lines. Fish eyes occur when some of the coating is affected by foreign substances on the surface of the object being coated or mixed into the paint, leading to uneven adhesion and revealing the surface underneath. This is also a phenomenon where the coating forms many small circular spots or needle-like holes due to rapid solvent evaporation.
5. Floor Paint Wrinkling and Pinholes Issues
The surface of the coating shows wrinkling, mainly due to inconsistent drying speeds between the inner and outer layers, causing the surface to shrink and peel. Pinholes occur when a large number of bubbles form in the coating during mixing with the curing agent, and these bubbles continuously escape during the curing process, leaving marks on the coating and turning into pinholes.
6. Floor Paint Ring-Shaped Holes Issues
Uneven density of the substrate or insufficient dispersion of fillers can cause the surface to appear with ring-shaped holes, which we call ring-shaped holes. The solution is to carefully check the substrate before construction, addressing any issues before applying epoxy floor paint. Choose fillers with good dispersion and strengthen the management of material quality.
7. Floor Paint Roughness and Cracking Issues
Roughness refers to the presence of particles of varying sizes on the surface, mainly caused by undissolved impurities in the floor coating and external dust. Surface cracking is due to issues with the raw materials and construction quality, leading to reduced adhesion of the paint layer, resulting in peeling and cracking under external forces.
8. Floor Paint Peeling and Poor Coverage Issues
Peeling occurs when the floor cracks and loses its original adhesion to the substrate, causing the coating to come off in small pieces or completely detach from the surface under external force. Poor coverage and exposure of the substrate are mostly due to issues with the raw materials and construction. In summary, to achieve good epoxy floor paint results, it is essential to use high-quality materials and employ a professional construction team, as professionalism guarantees quality.
9. Floor Paint Curing Too Slowly
Curing too slowly means that the epoxy resin material cures more slowly at extremely low temperatures (10°C). Below 5°C, construction is absolutely prohibited. This phenomenon is closely related to viscosity; the lower the temperature, the higher the viscosity, making construction more difficult. Excessive curing time can lead to the coating collecting dust, sand, and other debris, and may even delay the construction period. Additionally, adding solvents at the construction site can also cause slow curing, as the evaporation of solvents takes away some heat and cools the coating.
