Allow the new wallcovering to dry and strengthen before hanging pictures or affixing other types of decor. Depending upon environmental factors and the type of material, this may take from hours to days to weeks. In shower or bath areas, always use the exhaust fan to remove steam and moisture which could otherwise cause the material to loosen from the surface, especially near the ceiling. For cleaning, you should follow manufacturer instructions included with the material. In general, naturals may be vacuumed, papers may be sponged lightly with clean water and vinyl may be washed with mild soap and rinsed with clean water.
