How to Preserve Log Cabins

Inspect the condition of the logs on the cabin. If it is an older cabin, check for dry rot, mold, mildew, insect infestation and UV damage. Use a hammer to tap along each log. Dry rot will evidence with a "hollow" sound when the log is tapped. Sweep the dust and dirt off of the logs as you look for insect holes. Check under the roof eves and around the foundation for moisture damage or mold or mildew growth. Used colored adhesive tape to mark an "X" at locations that require special attention or log replacement.

Use a hammer and chisel to carefully chip away any rotted log material until you encounter solid wood. Fill the damaged areas with wood epoxy, following the manufacturer's application directions.

Remove stains, mold and mildew by pressure washing the logs. If logs are severely stained or sun damaged, they can be returned to their original beauty by applying sand, ground corn cobs or walnut husks under pressure to "blast" away the surface debris. Log-blasting equipment can be rented, or you can enlist the services of an experienced log-restoration specialist. Allow logs to dry completely prior to application of preservative or stain materials.

Apply a petroleum-based log oil to preserve the beauty of the logs. The oil can be sprayed or applied with a wide brush. Cover exposed wood with two coats of the preservative. If desired, a colored stain can be added to the log oil to tint the wood. Apply the preservative when the temperature is above 40 degrees F and the logs are thoroughly dry. Warm sunny days will help the oil penetrate the wood.
