What should I do if the paint doesn t dry? What is the reason why the paint does not dry for a long

1. Wait more time in a ventilated environment for it to dry naturally. Or the paint film is sanded off and repainted.

2. If it is a small item, it is recommended to use low-temperature baking for artificial drying if possible. If the baking method cannot be used, it is recommended to scrape off the paint film and re-paint the project, and use the matching curing agent according to the ratio.

3. Use sandpaper or other grinding methods to polish carefully, completely polish off the topcoat layer or intermediate paint layer, and then re-construct the topcoat or intermediate paint after the primer is dry.

Reason: Too much humidity in the air and too low temperature.

Solution: The humidity in the air is too large, the temperature is too low, and the paint dries very slowly. If you have to work in an environment with high humidity, you can add an appropriate amount of slow-drying water to the paint.

2.Cause: The surface of the furniture contains moisture or grease.

Solution: Before painting, use a clean soft cloth and wipe around the furniture to remove moisture and keep the surface of the furniture dry. If there is grease on the surface, you can remove the paint on the surface, use the heating method to remove the grease, clean the surface and repaint.

The paint is not dry, there are many kinds of paint, there are single components, there are two components, there are polyester paint, there are alkyd paint, there are water-based paint, the drying time is not the same, polyester paint can generally dry in 2 hours, alkyd paint brush up to 7-8 hours to dry, water-based paint can be dry in about 3 hours, compare, is it not too short, it is not a matter of time, probably you brush the two-component paint, no curing agent added, if this is the case, re-oil, put a little more curing agent, see if it can be solved, There is also a solution, which is to go to the chemical store to buy paint stripper, brush it on the paint surface, take off all the original paint and re-oil

Tell you why, don't you have the right thinner?

Next time you remember to brush the varnish, remember to use the thinner!

Find a sunny and well-ventilated place.

If you wash it off, you can wash it with thinner or thinner!

When brushing, you should also use varnish and thinner, so that the brush dries very quickly.

Especially if you want to dry slowly, you have to open the window often to ventilate, or put an electric fan or hair dryer in the house to move the air quickly.

Hello, the reason why the paint does not dry may be due to the following reasons: 1. The painted surface contains moisture. 2. The amount of curing agent added is too small or the reinforcing agent is forgotten.

3. Use diluents with high water content and alcohol content. 4. The temperature is too low, the humidity is too high, and the dry conditions are not reached. 5. The one-time coating film is too thick, or the interval between layers is short.

Hope it helps.

Hello, I am glad to answer for you: 1. The reason why the paint does not dry for a long time Slow drying refers to the fact that the drying time of the paint film after the paint is coated exceeds the specified standard. The paint on the wall has not yet dried, and there is a phenomenon of stickiness, usually with fingers or with some sharp objects to touch, there will be a sticky, concave and convex phenomenon.

Stickiness means that the paint film does not stick to your hands when it dries, and after a long time, it softens and becomes sticky. The reasons for slow drying and stickiness are similar: 1. Improper surface treatment.

The residual oil, acid, minus, salt, etc. on the surface of the object are not completely removed, the pine resin, wax, and asphalt are not removed, and the primer is applied before it is completely dry, which will cause slow drying or local stickiness, and some even do not dry for a long time. 2. The paint is too thick, so that the oxidation only occurs on the surface, the solvent at the bottom cannot be volatilized, and the paint film can not be fully dried. 3. Poor construction environment.

The paint film is attacked by cold, rain, dew, smoke, acid, reduction or moisture; or paint in a humid and airtight room; or in the rainy season and foggy days, there is a large amount of moisture accumulated on the surface of the object; In addition, in the cold season, when painting slow-drying paint, there is no appropriate amount of drying agent added to the paint, or the moisture of the boudoir is too small when coating the large paint, etc., which is easy to cause the paint film to dry slowly or sticky. 4. Poor paint quality. The resin content in the paint formula is low, or the solvent with poor volatility or contains non-drying and semi-dry oils; The use of paint that has been stored for too long or the use of tung oil with too low refining temperature will also make the paint film dry slowly and sticky back.

5. Mixing different types of paints, or using excessive driers, will make the paint dry very slowly (causing the surface conjunctiva to be closed, making the inner layer dry slowly), and even sticking.

The main reasons why paint doesn't dry or dry slowly:

Environmental reasons: too much humidity in the air, too low in temperature.

Substrate reason: The surface of the coated object contains impurities such as moisture and grease.

Solution: 1. Spray after the water is completely dry.

2. Adjust the paint of the reinforcing agent according to the proportion.

3. Use the supporting diluent provided by the manufacturer.

4. Spray at normal room temperature.

5. Two or more constructions, prolong the construction time between layers, if the coating surface can not be dried, the coating should be shoveled off or cleaned off with a cloth dipped in acetone.

Summary. Hello, there may be several reasons why the paint does not dry for a long time:1

Low temperature: Low temperatures can slow down the rate at which paint dries. Paint applied at a lower temperature may take longer to dry than in a warmer environment.

2.High humidity: High humidity can cause moisture to form on the surface of the paint, making it difficult to dry.

Therefore, an environment with high humidity is not an ideal condition for paint drying. 3.Quality Issues:

Some cheap paints may contain more solvents, which take a long time to evaporate, causing the paint to dry slowly; Similarly, some paints may have too much thickener added, resulting in too long a drying time. 4.The coating is too thick:

Applying more layers of paint than the recommended thickness each time may result in a longer drying time for each layer of paint. 5.Types of paints:

Different kinds of paint dry at different rates. For example, paints may be oily and water-based, and the drying speed and quality of each paint may vary.

High humidity: High humidity can cause moisture to form on the surface of the paint, making it difficult to dry. Therefore, a high humidity environment is not an ideal condition for pure drying.

3.Quality problems: Some cheap paints may contain more solvents, and these solvents take a long time to evaporate, resulting in slow drying of paints; Similarly, some paints may have added too much thickener, causing the keys to dry for too long.

4.Coating too thick: Applying more layers of paint than the recommended thickness each time may cause each layer of paint to dry for a longer period of time.

5.Types of paint: Different kinds of paints dry at different rates.

For example, paints may be oily and water-based, and the drying speed and quality of each paint may vary.

Therefore, if you encounter the situation that the paint does not dry for a long time, you can check the ambient temperature and humidity and other factors, and pay attention to the thickness of the paint and the coating interval during construction.
