What color is good for latex paint? How long does it take for the formaldehyde in latex paint to dissipate?

What color should latex paint be used for home wall treatment? Generally speaking, if latex paint is used for wall decoration, it is recommended to choose light colors. Too dark colors will cause visual fatigue. For non-professionals, it is recommended to choose the colors prepared by the manufacturer to decorate the walls of your home. At the same time, it is necessary to use the color matching techniques introduced by the following Encyclopedia Knowledge Network. After painting, under normal natural conditions, the formaldehyde will evaporate to a usable level in more than three months.

What color is good for latex paint

1. If you choose latex paint for wall decoration, it is recommended to choose light colors. Too dark colors will cause visual fatigue. For non-professionals, it is recommended to choose the colors prepared by the manufacturer to decorate the walls of your home.

2. Yellow series: Cream yellow, a small amount of red, yellow and white latex paint; light yellow, yellow and white latex paint; orange yellow, red, yellow and white latex paint.

3. Red series. For watercolor, a small amount of red plus white latex paint; for bright red, red plus a small amount of yellow, black plus white latex paint; for brown red, red plus yellow and black.

4. Green series. For light green, a small amount of green plus white latex paint; for warm green, a small amount of green plus a small amount of yellow plus white latex paint; for dark green, green plus black plus white latex paint.

5. Blue series. For light blue, use a small amount of blue plus white latex paint; for dark blue, use blue plus black plus white latex paint; for duck egg color, use blue plus a small amount of red plus white latex paint.

What are the techniques for color matching of latex paint?

1. Be careful when mixing colors. Generally, try a small sample first to preliminarily determine the amount of paint to be matched, and then prepare a large sample based on the results of the small sample. First, mix the secondary color and the secondary color separately in a small container. Then add the primary color first, and then slowly and intermittently add the dark color with strong dyeing power, stirring continuously, and observe the color changes at any time.

2. When matching colors, there will be slight differences between the color of the latex paint and the color of the dried film. The colors of various latex paints are generally lighter when wet, and the color becomes darker when the latex paint dries. Therefore, if the sample is a dry sample, the color matching paint needs to be dried before color measurement and comparison; if the sample is a wet sample, you can drop a drop of the sample into the color matching paint to observe whether the two colors are the same.

3. When mixing complex latex paint, choose latex paints with the same properties and mix them together. The solvent system should also be mutually soluble. Otherwise, due to the poor miscibility of latex paint, it will affect the quality and even cause stratification, precipitation or gelation, making it unusable.

4. When mixing gray, green and other complex color latex paints, due to the preparation of multiple pigments, the density and oil absorption of the pigments are different, it is very likely that floating color and "flowering" phenomena will occur. At this time, a small amount of surfactant or leveling agent or anti-floating agent can be added as appropriate to solve the problem. For example, 0.1% silicone oil is usually added for prevention and control. Various surfactants produced abroad need to be distinguished in which solvent system they are used, and the amount added is generally 0.1% to 1%.

5. Taking advantage of the slightly transparent nature of the paint film, choosing a suitable base color can make the color of the topcoat more vivid than the original paint. This is based on the principle of natural light reflection and absorption. It is a color produced by the superposition of the base color and the original color. Paint engineering calls it "translucent color".

How long does it take for formaldehyde in latex paint to dissipate?

1. Unless you buy fake latex paint of very low quality, under normal natural conditions, the formaldehyde will evaporate to a usable level in more than three months. But if it is rainy or rainy, the harmful substances may not be evaporated in three months. So how long after painting the wall can you move in? Everything depends on the final test results, and children, babies, pregnant women and the elderly should be more cautious when moving in.

2. If you use high-quality latex paint, the content of harmful ingredients itself is not large. Through some solutions to speed up the volatilization, the formaldehyde in the room can be almost evaporated in one month. At this time, after the test, you can move in if the air quality meets the standard.
