How to correctly paint and tell you the precautions for painting

1. surface treatment before painting is very important

The main reason for the failure of painting is that proper surface treatment is not carried out before painting. According to the different conditions of the painted surface, the surface treatment can include: cleaning, maintenance, repair, grinding, masking and primer.

2. primer shall be applied before painting

In order to obtain the best brushing effect, some surfaces shall be primed before brushing. This shall be determined according to the specific conditions of the construction site and the brushing materials.

3. application amount

In addition to choosing the right product and color, you also need to estimate the amount of paint required. This requires first calculating the area to be painted, and then dividing it by the approximate coating rate of the paint you use. In most cases, it is better to prepare a little more paint to avoid going out to replenish the goods in the middle of the work.

4. be sure to remember the protection of finished products

Remove small pieces of furniture, curtains and photos, and cover large items and floors with covers; When painting, especially when alkyd paint and oily paint are used, doors and windows shall be opened to circulate air.

5. dilute the paint in proportion

If you like the darker room space, you will naturally choose the darker paint. It should be noted that when using the darker paint, you should try not to add any thinner to the paint, so as to ensure that the paint we use does not have color difference to a large extent. If you do not pay attention to the color difference, the whole room will be very ugly. If it needs to be diluted, it must also be diluted according to the proportion specified in the product description.

6. pay attention to the change of air humidity

Pay attention to the change of air humidity during painting. If the humidity is too high, the paint will dry very slowly, which will not only affect the progress of the project, but also affect the quality of painting during decoration; If it is too dry, the paint will dry too fast, and cracks will appear. That is not worth the loss.

7. the Paint Brush shall be of good quality

Some paint brushes are of poor quality and are prone to hair loss. When painting with such brushes, the brush hair is often hung on the paint surface. After the paint film is formed, it is left on the paint, which has a great impact on the effect of the paint. Therefore, when painting, try to use a better quality paint brush. If it is a new brush, pay attention to remove the hair that is easy to fall off on the brush.

8. do not paint too thick once

The paint shall not be applied too thick at one time, otherwise it will cause the paint to flow and look uneven. If this happens, it can be polished with sandpaper.

9. wait until the paint is completely dry

The second coat of paint must be completely dry after the first coat of paint is brushed, otherwise it is easy to wrinkle the paint film.

10. nail holes on the surface of wood products shall be repaired

In the process of woodworking, whether ordinary iron nails or air nails are used, nail holes will inevitably be left on the surface. One of the important tasks of painters is to repair the nail holes, otherwise it will not only affect the visual effect of wood products, but also affect the service life of wood products.
