Tell me about the wallpaper paint color mixing method and dosage?

1. Pay attention to the principles of paint color matching

Generally, do not use more than three colors of paint for color matching. On the basis of the primary colors, by adding white, you can get colors with different saturations (that is, colors with different shades). On the basis of the primary colors, adding black, you can get colors with different brightnesses (that is, colors with different brightness). Use red, Different intermediate colors (i.e. colors with different tones) can be obtained by mixing the three colors yellow and blue in a certain proportion.

There are two basis for color mixing:

One is color mixing according to written or verbal requirements, which is more convenient and easier for oil workers. But color selection is very important. If the color selection is inappropriate, the color matching effect will not be ideal. For example, when blending medium green, any yellow and blue can be blended into medium green, but only when the purity of yellow and blue is good, the medium green will be pure and bright.

The other is to prepare according to the sample requirements, which is highly demanding and highly technical, and cannot be easily accomplished by ordinary oil workers. Mainly rely on practical experience and comparison with the color swatch to identify which single colors the color swatch is composed of, what is the approximate proportion of each single color, and then use the same type of paint for trial matching. After being approved by the design and construction unit, the same or similar painting method as the model shall be used, and the same color as the model shall be painted.

2. Preparation of paint consistency If the paint consistency is too high due to storage or climate reasons, an appropriate amount of diluent should be added to the paint to reduce the consistency to meet the construction requirements. The amount of thinner should not exceed 20% of the weight of the paint, otherwise the film performance will be reduced. Thinner must be used in conjunction with the paint and cannot be abused to avoid quality accidents. For example, shellac paint requires ethanol, while nitrocellulose paint requires banana water.

3. Preparation of colorants. The preparation of colorants for wood surfaces is mainly water color, wine color and oil color.

When it comes to furniture paint color mixing, you must first Understand some color-related knowledge. The principle of the three primary colors is universal.

1. How to mix furniture paint

We talked about color earlier, now let’s talk about the mixing of color paint and the precautions; people with color blindness cannot mix paint and must Color matching under natural light. The color matching of paint should be carried out according to the color of the sample. First try to match the sample. After comparing the sample, make sure there are several colors of compound paint in it, and then put these colors of paint into cans respectively. Weigh the gross weight first, then use it to mix colors. Weigh it again after the color matching is completed. The difference between these three weighings is the weight of the various paint colors involved in the color matching. It can be used as a reference when mixing large samples. During the color matching process, The color paint added to the color matching should be added slowly, stirring constantly and checking at any time not to make it too much, from light to dark until it is registered.

Preparation of paint consistency If the paint consistency is too high due to storage or climate reasons, an appropriate amount of diluent should be added to the paint to reduce the consistency to meet the construction requirements. The amount of thinner should not exceed 20% of the weight of the paint, otherwise the film performance will be reduced. Thinner must be used in conjunction with the paint and cannot be abused to avoid quality accidents. For example, shellac paint requires ethanol, while nitrocellulose paint requires banana water.
