Exterior Inspection

When inspecting the general exterior of the building, look for:

  1. Landscape plants within 36 inches of exterior walls. Landscaping tips.
  2. Gutters & down spouts everywhere in good working order.
  3. Check for decaying wood within 12 inches of (or especially in contact with) ground.
  4. Wood piles at least 18 inches away from house.
  5. General patterns of fading of the finish.
  6. Look more carefully at areas that are most exposed to weather. South- and West-facing walls usually receive more sun exposure. Walls facing prevailing winds are exposed to more rain.
  7. Pay special attention to all logs and ends extending to or beyond roof overhangs.
  8. Make sure that no sprinkler directs water at the wall. Including water patterns on windy days!

Check for weathering patterns that can include:

  • Fading of the finish.
  • Water staining on exposed log ends.
  • Water staining on exposed walls.

Over the past several years we have discovered many things about cleaning wood and existing finishes.

Dusty-copyFirst and foremost is that chlorine bleach is not a good product to use. In addition to its potential for damaging the finish and bare wood fibers, its use and misuse contributes to a number of problems including the loss of film adhesion, discolorations due to tannin extraction, and the formation of iron tannates, streaks, blotches and premature failures of the finish system. We have also discovered that a number of wood and deck cleaners available at paint and hardware stores, home improvement centers and Do-It-Yourself outlets contain components that interfere with the proper performance of our finish systems.

With this in mind we have decided that the ONLY cleaning products approved for use with our finishes are those products supplied or recommended by Perma-Chink Systems, Inc. We are not doing this to increase our sales of cleaning products. It is simply because we have tested our cleaning products with our finish systems and have confidence that when properly used and applied, their use will result in the best possible appearance and performance of the final Lifeline™ finish. We cannot say the same about the use of other types and brands of wood cleaners and strongly discourage their use with any of our Lifeline stains.


Most preservatives offer some type of guidelines to the actual life expectancy of the product, but as a rule of thumb, left exposed to the elements, you can expect two to four years before a reapplication is necessary.

Typically, Shell-Guard is applied with a garden type pump sprayer, although for smaller jobs, a hand held mist type sprayer is more efficient. When in doubt, follow application recommendations found on the label.

Lifeline™ finishes bring your log homes appearance to life. All Lifeline products are waterborne, breathable, flexible, durable wood finishes which also highlight the natural beauty of your log home. There are Lifeline products available for both interior and exterior walls.

What are the benefits of applying an exterior finish?
