How to Stain Exterior of Log Home

Prepare the surface of the logs. Logs should be clean and dry before the application of stain or sealer. Use a stiff broom to remove all dirt and debris. Wash the logs. Start at the top, under the eaves and wash down to the foundation. Allow the logs to air dry for several days before proceeding.

Caulk or chink as needed. Chinking can be applied with a putty knife or caulking gun. Always read and carefully follow the manufacturer's label directions. There are dozens of different types of caulking and chinking materials available. Consult with a wood working professional for a recommendation of the correct choice for your home. (Allow caulking and chinking to totally dry before applying sealer or stain.)

Apply an oil-based penetrating sealer or sealer and stain combination. The sealer can be applied with a brush or an airless sprayer. (Wear eye protection and a dust mask when using a sprayer.) A sealer will protect the logs from harmful UV rays and highlight the natural color of the logs. A stain will change or intensify the color of the logs. The sealer/stain coats the wood fibers and protects them against mold, mildew and fungus. An oil-based penetrating sealer will keep the rain out but also allow any moisture trapped in the logs to evaporate.
