For several years our Lifeline™ Advance Topcoats have been an integral part of our exterior finish systems. In addition to prolonging the life of the finish system, Advance Topcoats help keep the exterior surfaces free of dust and dirt, and make them easier to clean. That’s because Advance is designed specifically as a topcoat. Unlike most topcoats on the market, Advance is not just a non-pigmented version of our Lifeline stain. Because we formulate our stains for maximum color retention and adhesion when applied to bare wood, we use an entirely different formulation to meet the performance criteria important in a clear topcoat.

One key for keeping your log home in tip-top condition is to take an hour or so a couple of times a year to inspect the exterior of your home for any signs of potential problems. Remember that a bit of maintenance and small, inexpensive repairs now can prevent expensive repairs later.

Both M-Balm® and E-Wood® are two component epoxies that are used for repairing soft spots, rot pockets and other types of defects in logs and timbers. Although they can be used individually, they are typically applied as a pair with each product playing a specific role.

It is virtually impossible to prevent logs from developing cracks and checks as they age and dry. That’s because as a large piece of wood seasons, mechanical stresses build up until the surface stress becomes so great that the wood cracks. We call these stress cracks “checks.”


Since interior finishes are not exposed to rain, snow, wind, and direct sunlight, long term resistance to weather is not an issue, and you have more flexibility when choosing the color and appearance of your interior wood surfaces. However, there are some parameters that need to be followed to assure you obtain the benefits of an interior finish, such as preventing odor absorption and making the walls easy to keep clean, while getting the look you desire as well.

All Lifeline™ finishes are water-based, film forming coatings. Although we refer to our pigmented coatings as “stains,” they do not “colorize” the wood like penetrating oil-based products; they form a film on the surface of the wood, thus protecting the underlying wood from the effects of wind, water, and sunlight. Since they form a film on top of the wood, they rely on proper surface preparation to ensure good adhesion.

The following are guidelines to follow after performing a borate treatment to your log home.

Shell-Guard® RTU

Washing – Never wash down a wall within five days of application. It’s really best to wait at least seven days. In practice, there are very few occasions when a wall treated with Shell-Guard RTU needs to be washed at all. As long as the first coat of finish can be applied within seven days of application, there is no need to wash it down. If, for some reason, there is a delay in applying the first coat of finish or discolorations or white residue is present, then washing with water or Log Wash™ may be appropriate but under no circumstance should the wall be washed less than five days after the Shell-Guard RTU was applied. Too much of the active borate will be washed away.

applyingborates2Ever since Perma-Chink Systems introduced borate treatments to the log home industry over 20 years ago, its products have been the preferred method of protecting log homes from wood-destroying insects and decay fungi. We are still the world’s largest supplier of borate-containing preservatives for log homes, and although there are other borate-based products now available, most are based on technology developed by Perma-Chink Systems back in the late 1980s.

During the winter months it’s important to be aware of the freeze-thaw stability of Perma-Chink’s products. The reason may involve shipping conditions, or whether it is okay to store a product or products in an unheated shed. In any case, you need to be aware of the consequences of allowing any of our products to freeze.


Can Lifeline™ Interior stains be used to finish interior floors? Technically the answer to this question is yes, but we rarely recommend them unless whoever is going to be finishing the floor fully understands the characteristics of water-based, transparent stains and knows how to apply them.
