Five effective methods to prevent epoxy flooring discoloration after construction

Many users have reported that discoloration occurs when using epoxy flooring, which affects the aesthetics of the site and makes people uncomfortable to look at. Below, we will introduce how to prevent discoloration of epoxy flooring:

1. Epoxy flooring should be thoroughly mixed before construction:

The density of several pigments in multi-color paint is different. Heavy pigments gradually sink and light pigments gradually float during storage. If not thoroughly stirred and evenly mixed during use, it will not match the original color after application.

2. Metallic pigments should be packaged with epoxy floor paint:

Metal powder pigments will turn black and green when stored due to corrosion from residual free acids in epoxy flooring.

3. Epoxy floor paint with high acid value should not be packaged in iron drums:

Varnishes with high acid values are prone to chemical reactions with iron packaging drums, leading to a decrease in transparency and darkening of color.

4. Choose the resin and pigment in the coating formula as needed.

Some pigments in the coating have poor light and heat resistance, and some resins have poor weather resistance and are prone to yellowing when exposed to light.

5. When designing the coating formula, attention should be paid to not using pigments that can react chemically with resins or additives. It is strictly prohibited to mix and color two different types of coatings without testing during the construction of epoxy floor paint. Some pigments undergo chemical changes, losing their inherent coloring power and causing fading or discoloration. Blue or green paints containing iron blue may fade during storage, but the pigments exposed to air after application will gradually recover.

The above content is an introduction to methods for preventing discoloration of epoxy flooring. We hope it will be helpful to you. By paying attention to these issues during use, you can effectively avoid discoloration.
