is it necessary to dispose of it all before painting the wall

plain ash is a layer of cover scraped by pure cement with a trowel. The purpose of this is mainly to cover up the quality problems of the civil base, such as cracks, hollowing, unevenness and so on. And blind the owner's eyes. Now, 80% of developers use a layer of plain grey to cover up their construction defects. They teach you a way to distinguish plain grey walls by scraping hard objects such as keys. The hanging pieces are plain grey walls, and the color is also very dark, similar to the color of wet cement.

the harm of scraping plain grey: when scraping plain grey, many do not add 108 glue, and the water in the cement will be quickly absorbed by the base, As a result, the cement cannot set normally, forming two skins inside and outside. Later, when tiling, the bricks will fall off and the putty will fall off

how to judge whether the plain grey should be eradicated:

1 look at whether the wall is white. Generally, the white is not added with glue, so it should be eradicated

2 knock with a hammer. Those that can be easily knocked off should be eradicated

some workers said that rolling glue can solve the problem, which is mostly an expedient measure. The problem of the length of falling off time should be eradicated

decoration failures caused by plain ash are common, which first appeared in Ziwei in 1996, and later in Rongqiao, Zhuque Lefu, triumph City, etc. It has caused great losses to the decoration company. Now large companies generally recommend that the owners eradicate it, otherwise they will bear the consequences of signing
