What are the precautions for paint application?

Home renovation will produce different home styles due to the different effects of paint. Even if the wall is painted with the same paint, it will produce a different home style due to the different painting process.

Let's take a look today to see which home paint brush is more suitable for you?

Paint application. 1. How many times do you need to brush the nitro varnish on wood products?

Normally, considering the relatively light and thin paint film of nitro varnish, professional construction personnel will paint the wall several times to achieve the best painting effect. Generally speaking, it is advisable to apply at least six times. Of course, there is one thing to pay attention to in the process of repeated painting, that is, the cleanliness of the wall, and the wall must not be repainted without treatment when the wall is contaminated with impurities.

2. Do the hardware on the wooden door need to be protected when painting?

In the process of painting, it is not uncommon to encounter hardware that has already been installed on the woodwork. At this time, some painters will choose to treat the hardware, wrap it with adhesive tape, or carry out the paint painting process without any treatment.

If the hardware accessories are not treated, paint will be painted, and the surface of the hardware will be corroded by the paint on the brush in the later use process, so it is particularly necessary to protect the hardware when painting.

Paint application. 3. How many times do you need to brush the ceiling and wall paint?

In fact, there is no strict standard for ceilings and wall paints, and it is said that they need to be painted several times. The number of paint coatings on the ceiling and walls is mainly judged by the light and thick color of the wall. For lighter colors, two times will do.

If the background color is darker, then it is necessary to consider the light and thick color of the paint, and the light one should be brushed several times, and the number of thick times can be slightly reduced.

4. Is it better to paint by hand or spray paint***?

For decoration owners who do not have professional construction knowledge, they will subjectively think that it is relatively convenient to blend paint, but in fact, this is not the case. In fact, the painting requirements of varnish are more strict and difficult than those of blending paint, and only the painters with better craftsmanship can paint better results.

In the case of blended lacquer, although the technique is relatively simple and easy to implement, its disadvantage is that it is a waste of materials.

Paint application. Basic knowledge of paint construction:

1) Why do pencil prints appear after the paint is applied?

The reason why pencil prints are seen on the painted walls is because some unprofessional or irresponsible painters start the wall paint work before the wall pencil prints are inspected and cleaned, so the pencil prints will appear after the wall paint is completed.

2) What kind of paint is better?

In the face of the dazzling variety of paints on the market, decoration owners are often dazzled. In fact, for paints and coatings, as long as they are healthy and will not cause fatal harm to the human body, green paints and coatings can be used.

Paint application.

It is understood that the acceptance of oilmen is best accepted while construction, and problems can be remedied in time. Which wall is completed is immediately accepted.

When the wall is painted and the painted wall is checked, you can rub the back of your hand on the wall repeatedly, and it feels smooth and smooth, which means that the work is in place. If the hand feels very astringent to the touch, and then look at the wall from the backlit direction, if the surface is uneven, there are obvious traces of the roller walking, indicating that in the construction process, the number of times the wall is painted is not enough, and the thickness of the paint layer does not meet the requirements. Normal painting is carried out once and twice for topcoat, and any time you cut corners will be shown from the flatness of the surface.

Qualified projects will appear very uniform in the backlight, and no traces of the roller brush can be seen.

Normal wall painting needs to go through the processes of putty, leveling, grinding, painting and other processes, which requires construction personnel not only to "use the heart, but also to the function". Usually, half of the wall painting effect is in work and half is in the material, so the selection of quality materials is also the key to ensure the overall effect.

Wood paint to see if there is a "fall". Carpentry works are mainly wooden cabinets and wooden ceilings. It is understood that the oilers of wood are divided into clear oil and mixed oil. Clear oil is to expose the texture of the material itself, and the oil mixture will completely cover the texture of the material itself.

When painting wooden cabinets, special attention should be paid to the details of the parts, if it is clear oil, the most critical place is the invisible details. For example, the bottom edge of the cabinet is the least noticeable place. If the paint kung fu is passed, this part is flat and smooth.

If there are some small raised bumps, if you look closely, you will find that the paint is solidified and formed by flowing down, which is called "falling". If there is a "sink", it means that the paint process is not up to par.

If it is mixed oil, it is necessary to see whether the surface of the mixed oil is uniform, flat and smooth, and whether the corners of the cabinet are also evenly painted.

3. In addition to choosing the right product and color, the amount of paint needed also needs to be estimated.

In most cases, it's a good idea to have a little more paint on hand so that you don't have to go out halfway through the work**.

Remember not to scrape off a piece of putty before it dries Generally speaking, the putty on the wall in home decoration is done twice, the first time is to flatten the entire wall, and the professional term is called leveling. The second pass is to do local treatment of the area that was not leveled in the first pass.

If this happens at some point, the putty on the wall will arch. Most of the reasons for this situation are due to the fact that the first putty is not completely dry, so the second putty is scraped on, and as a result, the second putty is arched during the drying process of the first putty.

Precautions for painting by yourself No. 2:

Precautions for painting by yourself No. 3:

To brush the paint, you need a good brush that does not shed hair. When brushes with a high lint loss rate are painted, the bristles are often hung on the paint surface. After the paint is filmed, these hairs will remain on the paint on the surface of the finished product, which has a great impact on the effect of the paint.

Precautions for painting by yourself No. 4:

Nail hole repair on the surface of wood products is critical, and carpenters will inevitably leave nail holes on the surface during the production process, whether using ordinary iron nails or using air nails. One of the most important things to do is to fix the nail holes.

Painters with better craftsmanship will repair the nail holes so that it is difficult to see them at a certain distance, while sloppy painters can still see the nail holes repaired at a certain distance. This not only affects the visual effect of the wood products, but also affects the service life of the wood products.
