The wall skin is removed and the latex paint is repainted, and the two people can be together because of their appearance and character, etc., but those who can stick to it until the end must be those who have the same goals for each other and have the same vision and ideas for the future.

Only when there is a high degree of consistency in the future development direction, can two people be happy for a long time whether they are together or not.

If two people who have not been together have a common goal, then the two people may soon be close to each other because of the common end, and move forward together, and it is easy to cross that hurdle with each other and go further. Two people who are together and have a common goal will also reduce a lot of conflicts and quarrels.

The "telepathy" between two people is really very important, and it completely determines the future direction between two people, so if you have not been able to form a tacit understanding with each other to the point where you can distinguish emotions at a glance, then you must observe carefully, feel and understand each other with your heart, after the existence of this "telepathy", it is easy to develop into the other half of the other party can not be separated.

The first step in wanting to repaint a wall that has been painted with latex paint is that the first step must be to clean the wall. The second step needs to be sanded, and some fine sandpaper needs to be used when sanding, do not damage the wall, and clean up after sanding. The third step is to prepare the latex paint, and then whitewash, after the putty dries, it must be sanded and smoothed, and then painted with a primer, so that it is OK.

Check the condition of the base treatment of the wall, which is currently only part of the inspection.

Look at whether there is hollowing and delamination on the wall, how the water resistance of the putty is, and how strong the base gypsum is.

If the putty has poor water resistance and low curing strength of the base gypsum, it is recommended to remove the putty and gypsum, and after the anti-cracking treatment, scrape the gypsum and water-resistant putty again, and then paint.

If you have as you said, you can first use a damp cloth to stuff the wall, after three minutes to see if it blisters, if it is not blistered, then you can directly buy paint and roll it on, if it is blistered, you need to re-remove the existing wall skin and then re-putty brush paint.

There is an existing latex paint wall, and I want to repaint the latex paint, and the treatment is as follows:

Old latex paint needs to be removed. The old wall must be treated with a wall base before brushing latex paint, and all the serious chalking should be removed, and then the putty powder must be re-brushed, and then the latex paint must be brushed.

If you re-paint latex paint, the quality of the wall is not good, it will affect the later decoration effect and service life, and will also have an impact on the overall environment of the home. Whether it is wall paint, wall tiles or wallpaper, if you want to renovate better, you should reprocess the base part of the wall.

Due to the aging of the material, the water-resistant putty of more than five years must be removed to the bottom of the wall during the second decoration, otherwise it will affect the construction quality of the wall latex paint in the future and the long-term use effect after decoration.

Some people have this problem: I painted the latex paint wall a few years ago, but some small cracks appeared. Can I paint latex paint again?

The answer is yes! In fact, it is very simple to paint latex paint again, mainly including removing dirt, rolling the frame, mixing and applying latex paint.

1. Before you want to paint latex paint again by hand, you should use ordinary detergent or water to remove the dust and dirt from the wall and wipe it dry. If there are nails on the wall, remove them first and fill them with filling. There is an option to fill small cracks with high-quality sealant.

2. Secondly, use the "frame" to paint the outer edge of the wall, and then use a roller to roll in the "frame". An effective roller coating method is to roll a large "W" or "M" shape on the wall with roller coating, which is then filled and rolled in different directions.

3. The most important point is that the latex paint is mixed with water and added to the roller coating, and the proportion of water is usually 20 to 30 percent (volume ratio). If there is too much water, it can easily lead to poor film formation of latex paint.

4. Stir the paint and water evenly, and then let stand for 20 minutes to achieve the purpose of defoaming. This will prevent pinholes or small bubbles from appearing on the walls of the latex paint.

5. Wet the wool brush and the roller with negative angle with water, and then dip. It is then coated with latex paint.

1. The paint brush should try to remove floating hairs before use. The way to remove floating hairs is usually to apply a little paint to the paint brush, rub the rough surface repeatedly to cause the floating hairs to fall off, and then scrape from the root of the brush to the tip of the bristles. Scraper, scrape several times, and finally brush the paint brush on the sandpaper and trim the tip of the paint brush into a neat flat shape.

2. Before using a new paint brush, it can be immersed in the nitrocellulose varnish or shellac paint at the root of the brush, so that the bristles can stick to the roots as much as possible, so as to prevent the roots of the paint brush from sticking to the hair.

3. The paint brush should be cleaned after use.

Through the above introduction, you must have a certain understanding of how to brush latex paint again. If you encounter similar problems in your future life, you can refer to the steps and precautions mentioned in this article, hoping to help friends who want to paint latex paint on old walls again.
