Quick Answer
LOG FINISHES FOR EXTERIOR LOGS SHOULD PROVIDE A DURABLE WATER-BASED COATING THAT RESISTS WEATHERING, UV LIGHT, AND MINERAL STAINS. THE BEST FINISHES OFTEN INVOLVE A LAYERED APPROACH WITH SEALANTS AND WAXES, AND SHOULD BE APPLIED ACCORDING TO MANUFACTURER'S INSTRUCTIONS AND PROPER PREPARATION TECHNIQUES.
Choosing the Right Finish
When selecting a finish for exterior logs, consider the type of wood, local climate, and desired level of maintenance. For example, western red cedar and cypress logs can be left unfinished, while other species like pine and spruce require a protective coating. Water-based log finishes like Sikkens, Olympic, and Thompson’s WaterSeal are popular choices due to their eco-friendliness and ease of application.
Applying the Finish
To apply a log finish, first clean the logs with a mixture of TSP (trisodium phosphate) and water to remove dirt, grime, and mildew. Allow the logs to dry for 24 hours before applying the finish. Use a high-quality brush or foam roller to apply the finish, working from the bottom up to prevent drips and runs. For a more durable finish, apply multiple thin coats, allowing each coat to dry according to the manufacturer’s instructions.
Maintenance and Touch-Ups
Regular maintenance is crucial to extending the life of your log finish. Clean the logs annually with a mild detergent and water to remove dirt and debris. Apply a maintenance coat of finish every 2-3 years, or as needed, to maintain the protective barrier against the elements. For touch-ups, use a small brush to apply a matching finish to any damaged or worn areas, following the manufacturer’s instructions for application and drying times.
