Problems with paint, questions about brushing paint?

Brush paint steps.

1.Make sure that the surface of the brush is smooth and sand with a considerable amount of sandpaper.

2.The consistency of the primer is felt according to the density of the painted surface, and if the density is high, the paint needs to be diluted. If the density is low, then you need to adjust the viscosity.

3. When painting, it should be evenly brushed along the texture of the wood, not too thick, and sanded with sandpaper after it is completely dry until it feels smooth and has no protrusions, wipe it several times with a damp soft cloth, and finally wipe it dry.

3.Brush the second coat of paint, whichever is the first coat of paint, and then gently and evenly sand with water sandpaper in the direction of the brush.

4.Brush the paint for the third time, and use finer water sandpaper dipped in water to polish after brushing, the strength should not be too strong, and the polishing should be even.

5.The last coat of lacquer does not need to be polished, and a layer of protective wax can be used.

Paint can be said to be a very important decoration for interior decoration, so if your skills are not enough, it is recommended to ask professionals to decorate.

Precautions for brushing paint:

1. Try not to mix water with dark paint, otherwise it is easy to have color difference; It is best to complete the painting at one time, otherwise it is easy to have color difference.

2. Do not paint in wet weather or winter, otherwise it will affect the overall construction quality, and the paint is not easy to dry.

3. Pay attention to indoor ventilation and heat dissipation, and the grinding of paint and paint should be carried out after it is completely dry.

4. When the brush is finished and waiting to dry, soak it in water, and see if there are bubbles in the brushing place, and if there are bubbles, they will burst immediately.

5. When the brush is dipped in paint, the part of the bristles immersed in the paint should not exceed half of the hair length, if the root of the bristles is stained with paint, the paint brush will be deformed, and the service life of the paint brush 4 will be shortened.

6. The paint brush stained with paint must be gently wiped on the inner surface of the container before brushing to remove the excess paint so that the paint does not drip on the ground.

Hand brush in the painting needs to be stained on the bottom of the wall a little paint, and from the bottom to the top and then from top to bottom in turn, in the process of taking the paint must shake off the excess paint, so as not to cause the wall and ground to be painted pile-up, thereby affecting the aesthetics of the wall, do not repeat the painting in the process of painting.

When the paint is constructed, when the paint mix ratio, the base wall and other improper treatment, you will encounter some common quality problems, below, I will share with you to solve the common problems of paint construction quality, I hope to help you!

Discoloration or bluishing

Reasons:1The moisture content of the base layer is too large.

2.The base layer is too alkaline.

3.Chemical gases are generated in the construction environment.

Solution: 1Allow the base layer to air dry completely.

2.The cement base should be cured for a period of time when it is dry.

3.It is strictly forbidden to apply at the same time as polyurethane paint, if it has been used, the wall can be lightly sanded with sandpaper, and then primer and topcoat.

Chromatic aberration prevention measures

1.The whole batch of engineering raw materials is purchased, and the inspection materials are sent to the factory to enter the construction site for re-inspection, and the inspection is re-inspected before construction to ensure that the color and luster are sold and the color difference is eliminated;

2.In strict accordance with the construction requirements, the raw materials are evenly stirred before construction, and the specially appointed person is responsible for handing over the evenly mixed materials to the spraying personnel in a timely manner;

3.Before the construction of the sealing primer, the surface layer of the wall is leveled;

4.Strictly control the construction process and prohibit the spraying of different colors of paint at the same time.

Sensory effect of technical measures

1.Keep the spraying pressure and paint consistency constant, and stop the spraying construction when the wind speed exceeds 5-6% seconds;

2.Strictly control the finished coating product before construction, and continue to be uninterrupted during the topcoat construction;

3.Maintain an appropriate spraying distance and maintain a moderate density of the paint;

4.Do not apply under the wind, and the thickness of the coating should not be too thick each time.

Chalking phenomenon

Mascot Reason:

1.The base layer has a powder layer. oil stains, etc.

2.The temperature is low when applied. Film formation is not good.

3.Too much water seepage from the brush.

4.Poor weatherability of painting.

5.The surface of the wall is not treated.

Solution:1The old topcoat with a loose surface should be applied before painting. Dust. Oil stain removal.

2.The construction temperature should be kept above 5 degrees Celsius.

3.Reduce the amount of seepage water.

4.Apply two coats of weather-resistant topcoat.

Sag

Reasons:1The thickness of the paint film is too thick at one time.

2.Add too much water when applying.

3.Excessive ambient humidity.

4.The lower layer of paint is not polished and adheres poorly.

Solution:1Apply paint several times, and it is not advisable to finish it all at once.

2.Reduce seepage and tease the amount of water.

3.Reduce ambient humidity and avoid construction in weather with excessive ambient humidity.

4.Polishing the surface of the object to be painted.

In modern home decoration, paint is essential, it not only beautifies our house, but also very practical, but many people in the purchase of paint, it is easy to go into the wrong place, so how to choose indoor paint? And how can we avoid falling into the wrong place? Let's take a look.

First, repackaging and ignoring the inside.

When consumers buy, they often come first with its outer packaging, which is right, but we can't only pay attention to the beauty of the appearance, but ignore the internal quality of the coating. The more beautiful the packaging, the more we have to look at its quality. Therefore, when purchasing, consumers can ask the formwork store to take out the detailed test report of its product to view, if not, it is recommended not to buy.

Second, focus on quality and ignore quality.

When many consumers buy wall paint, it is easy to fall into the misunderstanding of focusing on quality and ignoring quality. Some people think that the higher the coating, the better the quality, the lower the quality, the worse the quality of the coating, in fact, this is a big misunderstanding. Therefore, when consumers buy coatings, they can choose more well-known paint brands, which will be much more insured.

3. Do not estimate the amount of paint used in advance.

Many consumers do not estimate the amount of paint in advance, began to buy paint, in fact, this is the wrong behavior, if you buy more, it will cause a waste of materials, increase the cost, if you buy less, you will run a trip, so when purchasing, you must pile up too much paint at the same time to have a certain impact on construction safety. Therefore, it is recommended that the owner must estimate the amount of paint used before construction.

Fourth, odorless is environmentally friendly.

Many consumers judge the safety of wall paint by smelling, which is true, but many people think that low-odor or odorless wall paint is green, which is a big misunderstanding. Because many businesses will add flavors to paints to achieve odorless in order to obtain profits, odorless coatings are not all environmentally friendly and non-toxic. The professional way to judge the environmental protection of wall paint is to see whether its environmental protection indicators meet the standards.

Fifth, the color card is exactly the same as the color of the wall.

Many consumers think that the color of the paint on the color card is exactly the same as the color of the wall, and such a paint is good, but in fact, it is not, this is a misunderstanding. Because of the reflection of light, etc., after the four walls of the room are painted, the color of the walls will look darker than the color card. The color that consumers see on the color chart is often different from the actual color of the paint on the wall.

Well, the above is about people when buying paints, will walk into some of the misunderstandings, do you recognize it? I hope that the results of the collation can help people in need.
