Furniture is sometimes decorated with tree bark to give a rustic appearance. Birch and black ash are the most common types of bark used on furniture. Often, over time, the bark will begin to peel away. Before it peels off entirely, you can stop the peeling and repair the bark. You also can do a few things to prevent the bark from peeling in the first place.
Move the piece of furniture to another area of the home that has more ideal relative humidity levels -- between 30 and 60 percent. Determine the level with a humidity gauge if necessary. A new spot will stop further peeling and may prevent other bark from peeling.
Alter the humidity level if you don't have a spot with the ideal level. Add a dehumidifier to the room if high humidity is an issue, or use a humidifier -- especially during the winter -- to help raise the humidity level.
Maintain the humidity levels as much as possible. Fluctuations in humidity are the main reason bark peels off furniture.
Keep the room's temperature levels consistent throughout the year, if possible. Fluctuations in temperature are another reason bark peels from furniture. At the least, avoid great fluctuations in a short amount of time.
Apply wood glue to the back of peeling bark. Press it back into place on the furniture. Do not let the glue seep out around the edges of the bark. Hold the bark in place by gently hammering in small staples or brad nails in an inconspicuous spot. Remove the fasteners carefully once the glue dries.
Don't use tape to hold the glued-down bark while the glue dries.
