Drywall is used in home construction because it is inexpensive and dependable and can be repaired if it is damaged in any way. Regular maintenance on drywall can fix small problems before they become larger ones. One problem with drywall occurs because people and animals live in the house. Any roughhousing or moving of furniture can result in small holes and dents that need to be patched up. Larger holes require more maintenance. A large hole is enlarged to a regular shape. A large piece of drywall is cut to fit the new hole and it is patched. After painting, such holes as these will not be detectable.
People and animals can also have a destructive effect on corners. Even though these corners are reinforced, they often become chipped or flattened by being bumped into. These small sections of the reinforcing material can be replaced during regular maintenance.
Sometimes settling to the house will result in nails popping out of the drywall. During maintenance a professional can remove the popped-out nails and replace them with screws to ensure that the nail will not pop out again.
Plaster is an older type of interior wall. This type of wall is very durable, but cleaning it with moisture can be a problem. Some marks on a plaster wall can be removed with a common eraser or a slightly damp sponge. Any mark that penetrates the surface with have to be removed by scraping it off and repairing the plaster.
Repairing the plaster when it gets scrapes and dings is similar to repairing it for stains. Plaster walls are repaired using the plaster to fill the ding or the scrape with plaster and blending it to match the surrounding wall. A regularly scheduled maintenance plan can catch any such dings and scrapes and result in a pristine wall surface.
