How to brush latex paint

1 check

Comprehensively check whether the cement wall to be painted in the blank room is solid and flat. If the plastering layer on the wall is not firm enough or there are big cracks and holes, it is suggested to complain to the developer or property and ask it to do it again. If individual holes are repaired by themselves, they can be filled with gypsum.

2, finished product protection

There will be dust when dealing with the wall, and putty, paint or other glue will inevitably drip, so we must protect the finished indoor decoration products in advance.

3. Preparation before scraping putty

Ensure that the wall is firm and smooth, and clean the wall with a steel brush or other tools, so that the cement wall has no floating soil, floating and sinking as much as possible. Roll-coat the concrete interface agent on the wall as evenly as possible, and blow putty after it is dried (generally more than 2 hours).

4, blow be bored with child

Before plastering putty, measure the flatness of the wall (with a measuring ruler of more than 2m).

Determine the method of scraping putty. Generally, putty can be scraped on both sides of the wall, which can both level and cover the background color. Putty with poor flatness needs to be scraped several times locally. If the flatness is extremely poor and the wall is seriously inclined, you can consider scraping gypsum for leveling first, and then scraping putty. The interval between batches of putty scraping should be more than 2 hours (after the surface is dry). Matters needing attention in latex paint coating

1. After the paint is bought, it must be diluted properly. To obtain an ideal paint film, it is about 15% ~ 20%, depending on the instructions. Some good paints don't need water, but for the convenience of workers, they can add no more than 10% water.

2. Remember to wash the tools thoroughly with clear water after painting to ensure reuse.

3, see if there is any precipitation and caking on the coating. After a period of time, a thick and elastic oxide film will be formed on the surface of genuine latex paint.

Not easy to crack; Defective products will only form a film, which is fragile and has a spicy smell. 4. Smell whether the paint stinks or smells. The truly environmentally friendly latex paint should be water-based, non-toxic and tasteless.

5, you can brush a little paint on the cement wall, and scrub it with a wet rag after the paint dries. Real latex paint rubbing once or twice will not have obvious influence on the coating; The low-grade water-soluble paint will fade after rubbing for more than ten times.

6. Mix the latex paint evenly with a stick, and then pick it up with a stick. When high-quality latex paint flows downward, it will be fan-shaped. Touch with your fingers, genuine latex paint should feel smooth and delicate.

How to paint the wall with latex paint without cracking

1, paint latex paint from details.

Brushing latex paint seems to be a mechanical action up and down, but it is hidden and needs to be treated with caution. Improper paint and poor primer will lead to quality problems such as wall falling off.

In this issue of "Direct Hit Site", we came to the construction site in the construction stage of Fudi Yuzhongshan latex paint. It was found that all the finished products on the site were protected and the whole site was clean and tidy. Look at the details, before the latex paint brush, the ground must be painted with putty, so that the vertical leveling can be guaranteed when the baseboard is installed later. 2. The latex paint process needs to be prepared for the installation stage.

As the last link in decoration construction-the key construction project before installation, latex paint technology directly affects the effect and quality of installation project. For example, after the latex paint is brushed, the tape should be cleaned first, so that the later installation will be more convenient. Such cleaning work is also manifested in the cleaning of the lamp trough. After the painting process is completed, the dust in the lamp groove should be cleaned with a vacuum cleaner in time.

Top coat is usually brushed twice, and the interval between each time should be more than 2-4 hours (depending on the surface drying time) until it is basically dry.

After the second painting, it takes 1-2 days for the topcoat to completely dry. Before the paint is completely dry, it should be waterproof, drought-proof, sun-proof and prevent problems with the paint film.
