What temperature is better for application when brushing paint?

The temperature required for paint construction is lower than 5 degrees and not higher than 35 degrees, and the normal temperature is more suitable at 15 degrees to 25 degrees. Because if the temperature is too low, the paint is easy to solidify, and it is uneven and easy to agglomerate when painting, and the temperature is too high, which is easy to deform and delaminate the board and affect the construction effect.

It cannot be lower than five degrees Celsius. When decorating in winter, the putty should not be scraped too thickly. Because the indoor air is dry, the water loss is faster, otherwise it is easy to cause hollowing, cracking, and wall inequality.

Painting also needs to consider the temperature, will the high temperature have any adverse consequences for painting?

Hello dear, glad for your question. Painting also needs to consider the temperature, will the high temperature have any adverse consequences for painting? <>

Hello friends, the answer that has been queried for you is:1If you paint when the weather is very hot, because the temperature is too high, the water evaporates quickly, so it is very easy to make the paint solidify quickly, so the paint that has just been opened in this weather is very unstable, and it must be used as soon as possible to prevent deterioration.

2.When painting in hot weather, if the painting speed cannot keep up, there will be a situation where this piece of wall is dry, and that piece of wall has not yet begun to be painted, which may cause a certain color difference and make a beautiful appearance. 3.

Too high temperature will also cause the solvent to volatilize too quickly and the coating film is poor, that is, it may cause the surface of the coating to dry quickly, but the bottom layer is very slow, which will make the uncured coating film easy to be contaminated with fine particles such as dust, affecting the quality of the coating. 4.If the surface temperature of the wall is higher than 50 degrees Celsius, the painting work is still carried out, then when the wall temperature drops in the future, the freshly painted wall is very prone to cracks, and the freshly painted wall is directly exposed to the sun at this high temperature for a long time, which directly accelerates the speed of yellowing and fading of the wall.

Under normal circumstances, it must be more than 8 construction to ensure quality, and the minimum temperature of the construction environment shall not be less than 5 or less, and there are three examples of capacity: polyester paint: 18 -25, relative humidity is less than 75%; Nitro paint:

18 -25, the relative humidity is lower than 75% (the relative humidity is higher than 95%, the nitro paint can not be constructed, the humidity is lower than 0, the humidity is greater than 75%, which will cause slow drying, slow reaction, loss of light, whitening, etc.); Latex paint: more than 5, the relative humidity is less than 85% (theoretically, the minimum film-forming humidity of latex paint can be adjusted to 0, but the paint film is thin when actually painted, and it is easy to freeze and destroy latex particles in a cold environment, and because of the low temperature of the film-forming environment, it is easy to cause incomplete film-forming.) Gang should be protected from cold and rain).

In the cold winter, only the maximum temperature at noon can meet the requirements of exterior wall coating construction, but the temperature is low in the morning and evening, so the construction personnel do not pay attention to adjust the construction time in time, and the coating film formation of part of the construction wall will be not good. The minimum coating temperature is 10, which refers to the surface temperature and air temperature of the substrate. Whether it's latex paint or oil-based paint, applying at low temperatures can make brush and roller coating very difficult.

Generally, 18 degrees to 35 degrees is more suitable.

The construction environment is required to be 5 40 and the relative humidity is below 85%. Construction should be stopped under conditions such as wind (wind force 4 or higher), rain, snow, etc.

The indoor temperature should not be lower than 5 degrees when painting the walls.

Wall paint refers to the architectural paint painted on the wall of the room, the temperature is not suitable for decoration below 0, the ambient temperature of the commonly used mixed color paint construction should be above 0, the ambient temperature of the paint should not be lower than 5, and the ambient temperature of the varnish shall not be lower than 8. Therefore, in winter, the decoration construction should ensure that the indoor temperature is at least not lower than 5.

And after the home decoration wall painting, the maintenance period is generally 7 days (room temperature of about 25 degrees), low temperature or high humidity should be appropriately extended, the maintenance period should have good ventilation, no water on the latex paint coating film, no scrubbing of the latex paint coating, and avoid bumping the latex paint coating.

Mainly depends on whether the humidity of the weather is large, if the humidity is too high, do not construct, as long as the humidity in the air is not very high, there is wind can be constructed. 1. The temperature of the day of painting, if the temperature is above 20 degrees and relatively dry, then it is okay to brush the wall paint twice a day, but pay attention to the interval, the general interval should be more than 2 hours; 2. The humidity in the air, if the humidity is large, or it is rainy weather, it is recommended not to paint to prevent the paint film from absorbing water and blistering; 3. If the humidity is moderate and the temperature is also suitable, you can brush it twice a day; But also pay attention to the polyester paint and brush separately to prevent reaction, resulting in the yellowing of the latex paint film; 4. In addition, when the paint color of the home is more than 2 kinds, and the color of the roof and the wall is different, it should also be brushed separately to avoid color confusion and waste of materials by repeatedly washing the brush.

If you want to decorate a house, you must paint it, which can not only increase the aesthetics, but also increase the comfort, and different colors of paint can also give people a different feeling, but you know what? Painting also needs to consider the temperature, when the temperature is very high, painting will also produce a lot of adverse consequences, especially in the summer high temperature and high humidity weather, we must pay more attention to the following problems!

If you paint it when it's very hotBecause the temperature is too high, the water evaporates quickly, so it is very easy to make the paint solidify quicklyTherefore, the paint that has just been opened in this weather is very unstable, and it must be used as soon as possible to prevent deterioration.

Hot weather. When painting,If the painting speed cannot keep up, there will be a situation where this piece of wall is dry, and that piece of wall has not yet begun to be painted, which may cause a certain color difference and affect the appearance.

Too high a temperature will also cause the solvent to evaporate too quickly and the coating will not form a filmThat is to say, the surface of the coating may dry quickly, but the bottom layer is much slower, which will make the uncured coating film easy to be contaminated with fine particles such as dust, which will affect the quality of the coating.

4.If the surface temperature of the wall is higher than 50 degrees Celsius.

The above is still being painted, so when the temperature of the wall drops in the future, it has just been paintedThe wall is very prone to cracks, and the newly painted wall is directly exposed to this high temperature for a long time, which directly accelerates the speed of yellowing and fading of the wall.

Each different type of coating drying and condensation has certain requirements for temperature and humidity, and has its best film-forming conditions, if you don't want to do more with less, it is recommended that you choose the right climate before you need to paint!

When the temperature is high, the evaporation will be fast, which will cause the paint to dry too quickly, which will affect the final effect. In addition, it is also a great threat to the health of construction personnel, and it is difficult for workers with heat stroke to supplement the quality of painting.

If the temperature exceeds 30 degrees, the painted paint will slide, resulting in a thin top and a thick bottom, and it is not easy to solidify.

Very high temperatures can lead to changes in the viscosity of the paint, which can occur when the walls are brushed with such paints, the uneven painting and the combination of paint and the wall surface are not ideal, and the smell of the paint becomes unusually pungent at high temperatures.

If the temperature is too high, the amount of paint is not easy to control, they will have different changes in the status quo, not easy to form, uneven and other problems are to be considered.

If the temperature is very high, it is not conducive to the solidification of the paint surface, and even affects the smoothness and delicacy of the overall wall.

If the temperature is too high when painting, it may damage the wall, and if the temperature is too high, the paint will be too viscous and not easy to touch.

In the process of painting, if the temperature is too high, it will have a great impact on the uniform distribution of paint on the wall, so the temperature should be controlled in the process of painting.

The condition of the paint is also important when painting, and if the temperature changes, the paint may be more fluid. In other words, if it will run down when he paints it, it may appear one by one.

Does the high temperature have any effect on the paint?
