If the sound is empty after tapping, it means that the wall has an insulation layer, and if the sound is dull, it means that the wall has not been insulated.

    If there is an insulation layer, it is necessary to check whether there are cracks in the exterior wall of the building, if there are no cracks, it means that the insulation material is not good, and it should be replaced, which is the best method.

    Scrape off or stick wallpaper.

In addition, about two days after the wallpaper is pasted, you can open the window for ventilation to remove formaldehyde.
