How often does it take to fan the ash again?

It takes a week to fan the ash for the first time before you can fan it for the second time.

Generally, the new house is dusted three times. If you are renovating, you'd better shovel the original dust before dusting it.

The approximate steps of the wall surface are as follows:

1. Clean the wall surface, and shovel out the old wall surface;

2. Find the level first and play the chalk line; ?

3. Use gypsum powder and 18 glue to level the angle of yin and yang;

4. After the gypsum is dry, scrape it twice with special putty, and polish it with sandpaper during the process;

5. After the putty is dried for the last time and polished flat, the latex paint primer and topcoat can be applied.

note for fan ash:

1. in order to prevent cracking after fan ash, it is very important to check the substrate first. Generally, there are three kinds of places that are easy to crack, namely, the digging part of the electrician on the wall, the patching part of the ceiling, and the intersection part of the woodwork and the wall. Therefore, before construction, it is necessary to focus on these parts. If cracks are found, they must be mended first and then dusted.

second, the general number of dusting depends on the condition of the wall. Fan all flat, until it is dry to a certain degree, start polishing, and the polished wall surface should be smooth and free from pits. After that, dilute the wall paint that needs to be constructed with appropriate water, and apply it by brushing or spraying. Brush it from top to bottom in sequence, and there should be no dripping latex paint on the wall. If it is found, it should be handled in time.

Third, pay attention to the weather problem when fanning ash. Don't do dust fanning in rainy season, because the wall is not easy to dry in wet weather, and it will be very easy to fog and water after dust fanning in continuous wet weather.
