Why can't putty powder make noodles?

In the first case, the bottom of the putty layer (gypsum layer powdering) loses powder, and in the second case, the gypsum base layer is poorly leveled, with large potholes and hot weather, and hot water is discharged. The third type: the moisture and hot air at the bottom of the wall are caused by external discharge.

Treatment method:

The first type: shovel the putty layer. It is recommended to brush the interface agent for home improvement (environmental protection and formaldehyde-free corrosion protection). The interface agent needs to be made into putty after its surface is dry. The powder at the grass-roots level will fall off, and sooner or later all problems will appear. At that time, bubbles, delamination and peeling will appear on the whole wall. Glue is generally used for tooling, but if the powder falls off seriously, the glue can't completely deal with this problem, and quality problems will occur after at most one year.

The second type: shovel off the foaming place, find out the seam of the hole, and then fill the hole with leveling and plaster, without leaving blank. Then scrape a putty in the batch.

The third type: if you can't handle it, wait until the water is exhausted. Or shovel it all off, shovel it on the sand wall, use waterproof putty powder as the base, then use waterproof putty powder cloth (white) on the surface, and finally brush the paint without painting.
