Try not to open the shrinkage joints of the wall to the windward.

Do not forget to keep the windows and doors open during the construction period and within 24 hours after the construction is completed. Excessive ventilation will cause the wallpaper to dry sharply and shrink unevenly, causing cracks in the joints. After 3 days of paving, pay attention to adjusting the ventilation.
