Interior finish maintenance is minimal and is typically a non-issue. The reason such a statement can be made is closely related to the kiln-dried factor of the log walls. The most common interior finish product utilized is polyurethane. (Oil finishes are also fairly common). Since the logs are kiln dried the interior finish can be applied as soon as the home structure is completed. Note that a minimal amount of moisture can be present in the logs from the exposure to the elements during the construction process. This must be allowed to dry out for a short period of time.
With many of the air dried products on the market applying an interior finish is discouraged for up to a year after the completion of the home due to the concern of trapping excessive moisture within the logs. Bottom line on this as related to an Applewood log home is that by being able to apply the finish before moving into the home the maintenance factor is greatly reduced. A log wall after it is prepped for a finish is subject to all kinds of stains and normal abuse, which will have to be addressed prior to the final finish being applied. The good news is that this is not a consideration with a properly kiln dried log wall. There is very little maintenance involved once a wall has a polyurethane finish applied to it.
This is a very durable finish and is easily cleaned with common non-abrasive household cleaners. It would not be fair to avoid mentioning that logs and all wood products will naturally age in time. The almost white finish of a new log wall will tend to assume more of a honey color over time. This is thought of as being a good thing as with time it enhances the warm feeling that log homes are known for. It does not come without some concern though. When pictures, or other decorations, are hung on a wall the area behind the picture will not age at the same rate as the rest of the wall. If after time the location of a picture is to be moved or if the picture is to be removed a light spot will remain on the wall in the shape of the picture. To prevent this from occurring it is advisable to relocate pictures or other decorations from time to time.
