Logs have been a favored natural building material for centuries. Log homes are found all around the world, from small country cabins to majestic, palatial chalets. When properly constructed and maintained, many of these homes are as sound as they were hundreds of years ago. Yet logs are a natural material and can be damaged or deteriorate from weather, sun and humidity, as well as from neglect. Whether it be a new home that needs care, or a historical log home long abandoned, log homes can be restored to their original beauty. Does this Spark an idea?
Evaluate The Building
Carefully examine the building. Use a stiff-bristled brush or broom to remove all dust and debris so that you can clearly see the logs. As you clean the logs, look closely for insect infestation, mold, mildew, wood rot or damaged or cracked logs. Inspect the roof, under the eves, the floor support and the foundation. If possible, crawl under the building and inspect the floor joists, and evaluate the condition and serviceability of plumbing and electrical wiring.
Replace or repair all damaged or rotted logs. This may be as simple as replacing a porch support, or you may wish to hire a professional log home contractor for extensive repairs that impact the structural integrity of the building. Proceed with all necessary repairs.
Obtain a professional termite inspection. Termite infestation is not always visible to the naked eye. Treat as necessary.
Surface Preparation
Sometimes all that is need to bring the logs back to their original beauty is a good cleaning and then resealing. If the log structure has been exposed to dust, pollen or sun damage, minor efforts can correct the problem. However, if damage is extensive, consult a professional log restoration contractor before you do anything. Many fine old log structures have been severely damaged by excessive sanding or other failed do-it-yourself methods.
Rent ladders and needed scaffolds. Assemble your supplies and equipment. Blast the exterior of the logs using a ground-up glass, corn cob or walnut hull media. Consult with a professional log restoration contractor for an estimate and advice on your restoration project. Determine the level of experience, equipment and materials required for the job. Depending on the extent of the damage, you may elect to employ the services of a contractor, or you may want to do the job yourself. (Log blasting equipment and abrasive media are available from log home builders or equipment rental outlets.)
After the blasting is complete, use an electric hand sander to lightly sand the logs as required. This is the most labor intensive part of the project. Sand in the direction of the wood grain using 80- to 100-grit sandpaper. Be careful not to sand too heavily. You are removing a portion of the log that cannot be replaced. Use a leaf blower or damp rag to remove all sanding dust. Only sand where needed.
Use a chemical stripper to remove the failed paint or finish on decks, porches and roofs. Carefully follow the manufacturer's label directions. Always use gloves, a dust mask and eye protection when working with chemicals or sanding dust.
Caulking & Chinking
Repair or replace caulking and chinking as needed. Follow the manufacturer's installation instructions.
Preservation & Protection
Preserve the logs with a 10 percent solution of a boron-derived wood preservative. Commonly called "borate," this solution is applied using an airless sprayer. Apply as directed on the label. Cover with paper and tape off all windows, doors or decor items or plants to protect them from overspray.
Apply two coats of an oil-based penetrating finish. Apply as directed on the label. Do not use a "film-base" non-penetrating finish such a polyurethane or varnish.
