Staining & Finishing
Bring out the Beauty in Your Log Home
How do you know when it’s time to refinish your log home? An easy test is to sprinkle several logs with water from a hose or spray bottle. If the water is absorbed into the wood rather than repelled, it’s time to finish. Log homes generally need refinishing every 2 to 7 years because the stain wears out or is weathered off.
Repelling moisture and protecting against UV rays are the primary reasons to refinish logs. The key to a good finishing coat is compatibility with what is underneath. Preservatives and finishes must work together or the finish coat will fail. We recommend and use a family of compatible products from Perma-Chink Systems, Inc. Ultra-high-performance stains, such as Lifeline Ultra-2, have up to 5 times the tint loading as standard stains which block UV rays more effectively than other stains.

These are the refinishing rules we follow to preserve the look of your log home.
If you prefer to do things yourself, these rules are ones you’ll want to remember.
When applying a stain, follow the shade. Never use an interior clear coat designed and produced specifically for applying over your stain coat.
Use an airless sprayer to get the stain on the wall and then back brush to even out any lap marks and runs or uneven concentration.
Use a good brush, move fast, and never leave a dry edge. (Plan your application to always keep the wet edge).
Figure approximately 350 to 450 sq. ft. of coverage per gallon of stain. The actual number will be affected by the choice of product, age and porosity of the wood, and the application method.
A Note about UV Ray Protection
UV is the shortwave visible radiation from the sun. This high-energy radiation is what causes tanning, sun bleaching, eye damage, and cancer. When UV rays illuminate a log surface they induce a chemical reaction with the wood structure that decomposes the wood surface. This shows up as graying or other types of color change.
The goal of any exterior wood finish is to minimize the amount of UV that hits the wood. Water borne stains use a polymer resin to form the base of the stain. Embedded in this film are tints, various UV blockers and absorbers. The UV typically doesn’t damage the film (resin) but passes through to energize a chemical reaction with the wood that actually decomposes the wood under the stain.
