What should be paid attention to in painting construction in decoration?

For paint construction, many people don't know what details to pay attention to. Tuba rabbit Bian Xiao has compiled some detailed knowledge questions and answers for your reference ~

Preparatory work:

1. Why can't the putty be scraped before it is completely dry?

A: Generally speaking, the putty on the wall in home decoration is made twice. The first time is to level the whole wall, and the second time is to treat the parts that are not leveled locally. But sometimes we find that the putty on the wall is arched. Why? It is observed that most of the reasons for this situation are that the putty was not completely dried in the first pass, and the workers scraped the putty for the second time, resulting in the second time that the putty arched during the first pass.

2. What should I do before painting the ceiling and walls?

A: In the process of home decoration construction, sometimes due to the tight construction period, some necessary processes are easily missed by workers; Take the painter's operation as an example: before painting the wall and ceiling, clean the wall, sweep away the dust and excess putty on the wall, handle the cracks, protect the joint between the wall and ceiling and wood products, and prevent wood products from being painted. These are all made before painting.

3. Why is it critical to repair the nail holes on the surface of wood products?

Answer: For wood products, whether ordinary nails or pneumatic nails are used in the production process, carpenters will inevitably leave nail holes on the surface, and an important job of painters is to repair the nail holes; A good painter will make the nail hole difficult to see at a certain distance, while a painter with poor skills and sense of responsibility will see the nail hole clearly at a close distance, which will not only affect the visual effect of wood products, but also affect the service life of wood products.

4. Why choose a paint brush that won't lose hair?

Answer: Some workers use paint brushes with poor quality and love to lose their hair. When painting with this brush, they often hang the bristles on the paint surface. After the paint becomes a film, it stays on the paint, which has a great influence on the paint effect. Therefore, when painting, try to use a better quality paint brush. If it is a new brush, you should also pay attention to beating the hair that is easy to fall off on the brush, or light the floating hair with a lighter.

Actual operation:

1. How many times do you usually paint the ceiling and walls?

A: Generally speaking, if the background color of the wall is relatively light, the ceiling and the wall surface can be painted twice, but if the background color is deep and the paint to be painted is relatively light, it is necessary to brush it several times according to the covering degree of the paint color. However, it should be noted that the more times you use the paint brush, the better. If the paint brush is used too many times, peeling and cracking will occur.

2. Nitro varnish on wood products is generally brushed at least several times?

Answer: Because the paint film of nitrocellulose lacquer is relatively thin, the painter should brush it several times according to the situation, usually at least six times. But there is a premise, that is, the painter should clean the paint surface before painting every time, so as to prevent the paint painted later from covering foreign objects.

3. Is the hand-painted quality good or the painting quality good?

Answer: Some families use blending oil technology (using ready mixed paint, etc.). For people who don't know much about construction, this method seems simpler than varnish, but it is not. This construction method is much more difficult than varnish, which tests the painter's skill. The work done by workers with poor skills is prone to brush marks. Therefore, in order to improve the engineering quality, many construction sites have recently begun to use painting technology for mixed oil construction. The quality of this method is indeed much better than manual operation, but the disadvantage is that it wastes more materials.

4. What protective measures should painters take when painting hardware?

A: We sometimes find that when painting, hardware (such as door locks and hinges) is painted. ) installed on wood products. In this way, the owner will find that the surface of the hardware has been corroded after moving in. Therefore, before painting, painters should stick some single-sided tape on the parts that are easy to paint to protect the hardware.

Basic knowledge:

1. Why do some wood products see pencil marks after painting?

Some painters are irresponsible for their work. Before painting, they don't check whether there are pencil marks on the surface of wood products that have not been erased, so they paint directly, so pencil marks will be left in the paint.

2. What paint is used?

A: There are many kinds of paints on the market now, and all kinds of brands have them. In fact, as long as it is a man-made chemical product, it contains some substances harmful to human body more or less. We can't see which product is better at the price we can accept.

The paint project in decoration directly affects the service life of paint, even seriously affects health, so we should be particularly strict with paint construction and some construction precautions, but we can also let professional decoration supervisors help us control and handle Tuba rabbit decoration insurance.

Add a few more points:

1. When you brush, you must brush slowly to see if there are bubbles in the brush. If there is a bubble, it will burst immediately;

2. When the brush is finished to dry, it should be cleaned with water immediately and soaked in water;

3. Masks and glasses must be worn, the former can reduce the harmful gas inhaled, and the latter can prevent paint from dripping into eyes.
