In loving memory of our late president Rich Dunstan.

In The Beginning

In 1980 my neighbor told me about building a log home in Eastern Washington. He said that he loved the home and the lifestyle but was disappointed wind constantly blew and cold, harsh winters meant there was no real effective way to seal the gaps between the logs. The house leaked air and heat and wind-driven rain came right through the walls.

He tried various caulking materials with little success. Caulking around a bathtub or sink was significantly different from ‘caulking’ literally miles of seams between logs in a log house.  After a number of conversations and experiments, we discovered there was no readily available product that could seal the gaps, look like authentic chinking, and last more than a few months.

After months of trial and error it became apparent that if we were going to design a material that would be acceptable to our criteria, we would have to design it ourselves.

The product we were designing was to be a replacement for what was known in the Log Home Industry as “chinking” – the sealant that historically provided the seal between the logs.  A chink is a gap – as in Biblical Times, “A chink in his armor’. Therefore, chinking is a material to fill a gap. Throughout the centuries of constructing dwellings out of logs, numerous methods were used to seal in between them. Early builders used pretty much anything they could get their hands on to seal the gaps – mud, straw and mud, cow manure, or mixtures of cement and mortar.

This Michigan log home was completed by the homeowners over 2 years in 2016-2017. Red pine logs were regionally sourced from Wisconsin and northern Michigan. The homeowners peeled, sanded, stained, and sealed the log home themselves, making this home a beautiful labor of love.

The exterior is finished with Lifeline Ultra-2 Sequoia with Advance Gloss, and log gaps sealed with Perma-Chink Stone. Interior logs and beams were finished with Lifeline Ultra-2 Dark Natural and Advance Gloss topcoat for the rest. Gaps were filled with Energy Seal - Dark Natural for interior, Dark Walnut for exterior gaps.

"Using your products was so effortless with easy application, no odor, and easy clean up. We have recommended Perma-Chink to others who have log homes in the area." - Roger & Diane G.



How do I know what color your stain will be on my house?

Transparent stains develop color differently, depending primarily upon the wood species, the surface preparation, the application method and the kind of light illuminating it. Even photos can be edited in a way that alters the true color.

The only way you will really know how the stain will look is to try it on your wood. We will provide complimentary samples of Lifeline for you to try on your own wood before purchasing product.

Not just Beautiful, but also Durable!

In addition to building a strong home, you want to build a beautiful home, too, which is why the finished appearance of your logs is so important. No doubt that high-quality finishes will save you time and money in the long run. Longer lasting finishes equates to less labor expense over the life of the finish.

Q: Where do I use LIFELINE Acrylic clear finish on log homes?

A: Acrylic Gloss or Satin is an interior furniture-grade finish. Use it on log walls, ceilings, or any other vertical wood surface. Unlike the solvent-based finishes, it will never yellow and has no fumes. You can apply the clear finish by multiple methods - spray it, brush it, or wipe it on with a rag. It is available in Gloss or Satin sheen. 


Looking For Stain and Sealant In One?

Perma-Chink Systems® has extended our finish options for our customers with 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.

Painter Matt Willey is creating a mural at the Rifle Branch Library. The project will include events every Sunday through Sept. 9 — the scheduled day for mural completion.

Honeybees within the hive ‘think’ collectively. They are hard-wired to understand that their immune system is collective. Their health is based on the health of the hive, not the individual bee. A personal experience with a honeybee in 2008 sparked a paradigm shift for Matt Willey. He realized that human and planetary health are collective, although we rarely act like it. COVID was a reminder that we are truly all connected more deeply than we realize. The global hive Matt is painting is a metaphor for the connectedness of all things. Bees are a symbol for humans, trees, animals, pollinators, water, soil and everything in between…

What Do I Use on the Interior of My Logs and Timbers?

The inside is where you do most of your living. As such, it’s important to take time to select the right interior stains and finishes for your log and timber home. In this way, you will achieve an interior that is visually pleasing and performs well for years.

Sunlight can offer life to Earth, yet also be one of the most damaging objects in our world. While we relish the warmth from the sun and we love the summertime fun, the sun’s ultraviolet rays damage any surface that isn’t protected. For humans, we get protection from clothing and sunscreen. But for your log home, what does it get? What can be done to lessen weathering brought on by UV light?

Given enough time, the sun and environment will eventually wear down any exterior finish whether it is latex paint, oil-based stain, or a semi-transparent finish. The goal is to prolong the life of the wood as long as possible through a combination of home design and protective log finishes.

CHEMIST'S CORNER: Can All Wood Species Be Prepared the Same Way, Using the Same Cleaning Products?cedar log home

The obvious answer to this question is NO. Although all wood species contain many of the same components - including cellulose and hemicellulose and minor amounts of extraneous materials - it is the wood extractives that differentiate wood species from one another.
