When it comes to using elastomeric sealants, considering the potential movement of your wood is almost always a smart move. Some important factors to consider that impact wood movement are moisture content, species type, type of cut (flat tangential cut or quarter sawn radial cut) and local environmental conditions.  Not taking these into account has the potential to lead to costly repairs in the future.

family care for your dream home

There is no secret in retaining the beauty of your log home. A little care and maintenance along with the use of quality products designed specifically for log homes will keep your home looking great for generations to come.


The proper application of preservatives, stains and finishes is equally important as the prep work to the wood.



restore maintenance guide  STEP 1SURFACE PREP

 Over the years we have discovered that chlorine bleach is not a good product to use for cleaning wood surfaces, it contributes to several 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 several 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 wood stains and finishes.

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.

  1. If the wood has not grayed, wash the surface with Log Wash™ solution and a pressure washer no more than seven (7) days prior to staining. Rinse well and allow the wood to dry.
  2. If you are finishing Western Red Cedar, Redwood, Walnut or Mahogany, use Cedar Wash™, a ready-to-use cleaner, instead of Log Wash for better surface preparation and finish longevity on these specific wood substrates.
  3. If there are signs of grayed wood, use Wood ReNew according to the label along with a pressure washer. Rinse well and allow wood surface to dry before staining.
  4. If after washing there are still dark streaks or discolorations, use a solution of Oxcon™ on the entire wall. Rinse well and allow the wood to dry before staining.

Check for weathering patterns that can include:

  1. Fading of the finish.

To test your finish or stain, use a spray bottle to mist the logs with water. If the water beads up and runs off like a freshly waxed care, then it’s doing it’s job. If logs soak up water, then you’ll need another application of finish.

  1. Water staining on exposed log ends.

If you have exposed timbers on the underside of your eaves that extend flush with the overhang or protrude past it, the ends of these logs are susceptible to rot. Treat with Shell-Guard then sand and seal with Log End Seal.

  1. Water staining on exposed walls.

Check flashing around the windows to ensure that all water is being channeled out and down the exterior walls. Water stains of the logs or drafts around the windows or doors indicate that air and water is infiltrating your home. The right sealant is the solution for this problem.

Log Homes with an Existing Finish That is Still in Good Condition

If a maintenance coat of Lifeline stain or topcoat is going to be applied over an existing Lifeline finish, wash the coating surface with Log Wash solution no more than seven (7) days prior to staining. Rinse well and allow the wood to dry, then apply a fresh coat of stain or finish.

Perma-Chink Systems® has recently added another beautiful wood finish option for our customers. Unlike our traditional Lifeline film-forming wood finishes, Log & Timber Defense™ penetrates your wood. As it absorbs into the wood surface, it forms a strong lattice network within the wood, reinforcing and strengthening the entire system from the inside out. Due to its elastomeric nature and penetration, it greatly reduces the chances of peeling and flaking by leaving the system breathable to water vapor. Many penetrating oil-based finishes can also form a network but unfortunately often contain harmful flammable solvents that make working with them both dangerous for you and our environment. In contrast our Log & Timber Defense is water-based making it both easier and safer to work with.

Perma-Chink Systems® recently added another beautiful wood finish option for our customers - Log and Timber Defense™. Unlike our traditional Lifeline wood finishes, Log and Timber Defense penetrates your wood much like an oil coating. Once Log and Timber Defense penetrates the wood surface, it forms a strong lattice network within the wood, reinforcing and strengthening the entire system from the inside out. This mechanism greatly reduces the chances of peeling and flaking by leaving the system breathable to water vapor. Many traditional oil-based finishes can also form a network, but are often so high in solids that they can easily blister and peel. Vapor pressure builds up behind the thick, unbreathable solid film and pushes the film away from the wood. This leads to an unfortunate situation requiring removal of the compromised coating down to bare wood.

We often get asked this very question. To help answer this we must look to our experience both past and present. For 40 years now Perma-Chink Systems® has been working to develop products that meet both the demands of Nature and our Customers. The result of this experience has been a wide range of products that help solve specific needs. Our wood finishes can be split into four main categories: exterior film forming, exterior penetrating, interior film forming and specialty. Let us take a closer look at these products and discover what makes each one unique.

Designing a Fortress of Protection for Your Log Home


When I was growing up, I was fascinated with forts. I would often get together with friends from the neighborhood, and we would combine our resources and construct some rather elaborate fortresses. To test our handywork we would end our session with a great battle to decide whose fort was superior. Fast forward nearly forty years and I am still helping design forts! At Perma-Chink Systems the forts we are building are designed to protect your home against the forces of nature such as sunlight, wind, rain, dust, insects and microorganisms. Let us take a closer look at what our fort looks like.

Why do my choices regarding surface prep, stain, and color matter?

When it comes to choosing a finish system for your log home exterior there are many factors to consider and depending on what choices you make it will have a significant impact on the longevity of the finish system. For example, some of these choices include surface preparation, type of stain, and color choice. Let us take a closer look at each one of these factors and discover how they each contribute to a systems performance.

With so many different choices on the market for wood restoration and cleaning products, it can be confusing trying to decide just what to use. Unfortunately, when it comes to cleaning or restoring wood, there is no “one size fits all” approach. Each unique situation has a chemical solution that best solves that problem. Perma-Chink Systems understands these challenges and we have developed specific products to address each situation.

Applying and tooling Perma-Chink or Energy Seal sealant you need the right tools to make the job easier and quicker. Depending on the job and type of sealant needed, you have a few decisions to make regarding the tools and accessories you'll need for the project.

chinking applicationStarting Out On The Right Foot

Having the right tools at hand is critical for a good chinking job. The most popular tool for applying Perma-Chink or Energy Seal is the bulk-loading gun. This tool is available in two sizes, the 20oz. and 30oz. capacity and operates by pulling sealant straight from the pail.
