What is the role of Fiberglass Cloth during construction?

We all know that the walls of a house are made of cement and lightweight bricks. After the wall is built, cement mortar needs to be applied both inside and outside. Putty is required after plastering the wall. At this time, the entire wall needs to be covered with Fiberglass Cloth.

It has two functions, one is to prevent the wall from cracking later, and the other is to enable the new batch of putty or gypsum to stick firmly to the original wall.
When many owners are renovating, sometimes the walls of their homes need to be smashed down, or when they are shoveling the walls, they see some white Fiber Glass on the walls inside, which were posted by the developer at that time.
In recent years, when new houses are handed over, developers generally help with paving the roads, but some old houses do not have Fiber Glass on their walls. After a long time, there will be many small lines on the wall of the house. Many owners don`t understand what`s going on, and here`s why.
Nowadays, more or less, Fiber Glass are used around the edges of homes in terms of decoration. The editor will tell you a few places. During a renovation, a home that does not have new walls, living rooms, or bedrooms should have cable cans and living room ceilings. The joints between drywall and plasterboard, these are places where EVs are needed.
Homeowners who are about to renovate must see if there are Fiber Glass on the walls of the house. If not, you must ask about it during decoration. If you want to decorate an old house, you must also pay enough attention to this issue. The wall structures of old houses and new houses are different, and the probability of cracks on the wall surface is higher.
