When preparing epoxy floor paint color paste, in order to obtain accurate colors, it is necessary to master the two key knowledge points of complementary colors and extreme colors. Below, we will briefly introduce them to you:
1. Complementary colors
If two colors of light are superimposed to produce white light, the pigments of the two colors complement each other, such as red and cyan, green and magenta, yellow and blue. In pigment blending, two colors that can be combined to form gray and black are also complementary colors. In the three primary color matching diagram, the second color obtained by combining two primary colors is complementary to the other primary color. So purple and yellow, green and red, orange and blue are three complementary colors. In addition, complementary colors include olive and orange, lemon and purple red, reddish brown and green. When coloring paint, if complementary colors are used, the color will darken, become dull, and even turn gray into black. When two complementary colors are placed side by side, they can create a strong contrast in color perception. They should be used with caution in the color design of epoxy floor paint coating.
2. Extreme color
Also known as extreme color. Colors belonging to the colorless system that cannot be found in the light band, such as black, white, and gray. It is a neutral color, so it can be coordinated with cool and warm colors to create a harmonious tone, hence it is also called remedial color. If there are errors during the allocation process, you can try using this method to remedy them first.

During the manufacturing and use of ordinary flooring, due to the needs of mechanical processing and rust prevention, or for loading, storing, and transporting oil, it often comes into contact with various oil products based on minerals or animal and vegetable oils, with various organic additives or inorganic substances added. The presence of these oils seriously affects the quality of the floor paint coating project and is the main cause of the peeling and loss of protective effect of the floor paint coating. These oils are called oil stains. The process of removing oil stains from the coated floor before painting is called degreasing. It is aimed at obtaining high-quality floor paint coatings. Prior to painting, various preparatory work such as degreasing is carried out on the surface of the coated floor. It is the first step in the pre-treatment of the painted surface and the foundation of the painting protection work. The requirement for oil removal is to thoroughly remove all kinds of grease, dust, mud, sand, metal powder, sweat stains, and oil stains adhered to the surface of the coated floor during the processing project. In order to ensure the smooth progress of the floor paint coating project and form a high-quality protective floor paint coating, the degreasing process plays an important role in the entire floor paint coating pretreatment process.
Incomplete oil removal will seriously affect the adhesion of floor paint coatings, especially for polyurethane, chlorinated rubber, acrylic, and ethylene coatings, which will cause difficulties in coating and affect the drying performance of floor paint coatings. For single component floor paint coatings such as alkyd and epoxy esters, slow drying or non drying may occur. After forming a floor paint coating, it affects the corrosion resistance and decorative performance of the floor paint coating, causing blistering, peeling, and even the entire floor paint coating to peel off, which is one of the important reasons for the defects.
