2. If the old house has only been used for a few years recently, then the paint painted on the surface of the old house is generally latex paint, if the owner does not remove the wall skin, directly brush the latex paint on the wall, then during the construction process, the latex paint and the putty at the bottom will absorb the moisture contained in the new latex paint, and it is easy to fall off in the later stage, so you must shovel down the wall skin first, and then you can apply the refreshed latex paint.
