Every month we feature a contractor, business, or success story. Learning from others in the biz is the best kind of learning. This month, we’re featuring Tony Christensen with Kbartee Renovations.

Spring is upon us, which usually means business picks up. Tony with Kbartee Renovations has been in full swing through the winter, too. We’re grateful for the time he spent with us, sharing more about his business here in Sashco’s home state of Colorado. 

How did you get started in Log home finishing?

I graduated college with a degree I wasn’t going to do anything with and was looking for work. Scott Stropko (Sashco’s Western Territory Manager) was a good family friend and he asked if I liked working outside. I said yes. He hooked me up with Jim Davis out of Wyoming and I started four days later. I worked with Jim for 3½ years and decided that I didn’t want to travel as much anymore, so another business partner and I broke off on our own. I worked with my business partner here in Colorado for 11½ years. Then, about 18 months ago, I decided to split off on my own. Life. is. great! Every day I pinch myself to make sure it’s real. I have an incredible job and I get to work in some incredible places. When I decided to be sole proprietor, it was a little scary. I never thought I’d be this busy. It’s mind blowing. I’m so grateful. There wasn’t a day during COVID that I didn’t work. 

What is your favorite part of this work?

Restoration. I like working on older homes. I like it when homeowners haven’t liked their home for a while, but didn’t know they could get it the way they wanted. I simply apply expertise and elbow grease. I love taking a home, transforming it, and seeing how happy the homeowner is at the end. We’re restoring their dream. Their smiles make it all worth it.

What is your least favorite part?

Weather: It’s hard to work around the weather. But then, I had more working days in January and February of this year than I have in March and April because of spring snows. It’s also difficult to manage expectations for people who don’t know that we’re booked so far ahead. They call in June wanting their home done by end of the summer. 

What is your advice to a newbie?

I wish Sashco offered the Zero Failures Business Focus class when I started out 13 years ago. I’d be so much further ahead. I would tell people that your word and your reputation are everything in this industry. You better have an incredibly good work ethic and be able to work with lots of different personalities. Be willing to learn. Soak up everything. It’s paramount to do good work and maintain high-quality relationships in this industry. If you get a bad rep with homeowners, that’s also a bad rep with distributors and others in the industry. When you screw up (not if, because it will happen), be willing to fix things and learn from it. Don’t just cut and run. You learn who you don’t want to be before you learn who you do want to be. 

What does the future look like?

I’ve had opportunities recently to merge with another company or purchase another company, but I really like where I am now. I like having the smaller crew. It’s part of the appeal with homeowners, too. I’m the owner, I will be on the jobsite 85-90% of the time, they’re dealing with me from A to Z. I’ve gotten really good at selling that. There are people who I know want to grow. That was me at first. I have two guys working for me and they’ve caught on really fast. Eventually, I know I will need to ease back and let those guys take some things over. In 5 to 10 years, maybe they’ll want to buy me out and I can go buy my cattle ranch.

Speaking of cattle ranching, what is the meaning of Kbartee?

Kbartee is a brand my wife’s grandmother sewed into her wedding dress. It’s a K, a Bar, and a T. As a gift for our first wedding anniversary, my wife registered it. I wanted something different for a company name and this just fit. It will be the brand for our cattle ranch someday.

Thanks again, Tony, for the time. Hit Tony up to talk shop!

Outdoor hand rails and spindles, especially those not protected by overhangs, require specialized and more frequent care because of their extreme exposure to weather. 


Mark Nelson of Nelson Restoration was recently working on a job up in Grand Teton National Park. Mark needed specific information to share with key decision makers that compared preservation of log structures using older methods of mortar and linseed oil with modern products. Sashco was honored to partner with Mark provide a report outlining the pros and cons of historic preservation.  Below is that report. Mark was able to clearly communicate the value of using a specialized log restoration contractor who uses modern products and won some future business as a result.



Technical Report | The Role of Coating Breathability in Preventing Rot in Log and Timber Structures


It’s common knowledge that moisture trapped in wood will, over time, lead to rot. Because significant rot can lead to tens of thousands of dollars in repairs, it’s imperative to use a coating (stain, paint, varnish, etc.) that will both prevent most moisture from getting into wood in the first place, and also provide an escape route for moisture that does get into the wood. Voices on the internet and elsewhere would tell you that this has more to do with the breathability of the coating itself. Breathability is important, because no matter how carefully built, properly stained, or well-maintained a structure is, some liquid water will eventually get past the outer defenses and into a building. But the breathability of a coating is not the primary factor in preventing rot. So, what is?


Effects of Water on Logs and Timbers


Too much water vapor pressure can result in stain that peels, as pictured.


On any log or timber structure, liquid water from many sources — dew, rain, runoff, backsplash, snow, ice, sprinklers, cleaning, etc. — will get onto the surface of the wood. Once on the surface, that water will soak into the wood, unless a good stain or coating is there to block it. Bare wood, weathered wood, weathered or failing stains and coatings, joints, fasteners, insect holes, and — perhaps especially — unsealed cracks and checks are all excellent places for liquid water to get past the coating and into the wood. Once in the wood, the liquid water will naturally soak deeper into the wood.

As liquid water inside the wood evaporates, it expands dramatically. One teaspoon of water will expand about 1600 times to become approximately two gallons of water vapor! When that happens slowly, in cool weather or shaded areas, those forces aren’t too destructive, as the vapor has plenty of time to find a way out of the wood without doing much damage. However, when the liquid water turns to vapor quickly and the escape paths are limited, damage can occur. This often happens when a dampened log is exposed to full sunlight. The increasing water vapor pressure underneath the coating will literally push the coating off the wood as it tries to escape, as shown in the photo above. The resulting damage to the adhesion of the coating is the beginning of the peeling process. The more breathable a coating is, the easier it can relieve this back pressure by allowing the water vapor to pass through it with minimal or no damage.

The most common way to address the problem of water is to apply a coating that forms a continuous film on the surface, keeping most of the water from getting in, while making sure that it is breathable enough so that water vapor can escape with minimal or no damage. The vast majority of wood stains on the market are intended to perform this way.

The first job of a coating: Keep Water OUT!

Shedding liquid water is the first line of defense against rot. Keeping the underlying wood dry simply makes sense. Disappointingly, most commercially available stains and coatings are simply too hard and brittle to do this effectively. Logs and timbers expand and contract and twist and crack with changes in temperature and humidity, and as they relieve internal stresses. A brittle, hard coating applied on top of this constantly-moving wood simply can’t keep up with the movement. The result is cracks in the coating itself that usher water directly to the wood. Over time, this leads to cracks in the wood itself, as shown in the photo above, which allows even more moisture in. An elastic, or at the very least flexible, coating can move with the wood far better, maintaining a barrier to liquid water for much longer. Sashco makes Transformation Stain® Log and Timber to be as flexible as an oil can be, and Capture® Log Stain to be hyperelastic.


Shown here: sealants will not adhere to non-drying oils, leaving an easy entry point for bugs and water.



The second job of a film forming stain: Let Water OUT!

You read that right: breathability is the second line of defense, but it’s a bit more complicated than just the breathability of the stain itself. All of the following factors also affect the overall breathability of logs and timbers: wood species, density, texture, wood prep, any previous stains applied, cleaning chemicals or preservatives in the wood, penetration or non-penetration of the first coat, the amount or thickness of the stains or coatings, the number of coats applied, and more. In such complicated systems, we simply aim for minimal to no damage as the stain weathers.

Other Ways of Addressing the Problem of Water

The less common way of addressing the problem of water is to make a super-breathable stain or coating that vapor just passes right through. An eroding alkyd, an “oil-in-water” system (often referred to as a “hybrid” stain), quickly micro-fractures and ages into tiny flakes. Water soaks right into the wood, but also evaporates right back out just as easily. The micro flakes erode away instead of peeling. This type of stain needs to be reapplied every couple of years, but extensive prep is usually not necessary. Stains like these are ideal for decks and fences. Sashco’s Transformation Stain® Siding and Trim falls into this category.

Another way to accomplish super-breathability is by using a non-drying oil as the main component of the stain. Unfortunately, these stains are incompatible with sealants and chinking, keeping these products from adhering to surfaces coated with these non-drying oils. Sealants that don’t adhere are easy access points for moisture (as shown in the photo above). Every log home needs some sealing, at the very least around doors and windows. This is why Sashco and many other manufacturers stand firmly against using non-drying oils, as well as silicones and waxes, on log homes, all of which prevent sealants from adhering properly.

More to the Story

Proper staining counts! As we consider log and timber stains and coatings, one of the most overlooked places during a stain job is actually the inside of cracks and checks. Many people do a fantastic job of making the outside of logs and timbers look beautiful, while completely missing the inside of the cracks and checks. Leaving any crack or check that can hold water (like that in the photo below) unstained means there is a direct water path right into the wood, and that will cause rot, eventually. All cracks larger than
¼ inch wide should be sealed with backer rod and an elastic sealant like Conceal® or Log Builder®. Any crack smaller than ¼ inch wide and  ¼ inch deep should be filled with stain. (Excess liquid stain can then be brushed out, but it is important to stain ALL the bare wood.)

DO stain INSIDE checks

Checks and cracks like this can hold a lot of water and should be sealed to help prevent moisture infiltration.


Another overlooked opportunity is vigorous back-brushing. We are not talking about spreading the stain out evenly, but literally pushing the liquid stains or coatings into the wood using block brushes on poles. This (exhausting but effective) work actually pushes the stain into places it won’t flow — into the cells and the cell layers deeper down, forming mechanical stain-anchors deeper in the wood. Doing this really helps the stains resist the backpressure of the water vapor, making the stain job last much longer.

Proper maintenance counts, too! Eventually, even the best stains crack as the wood underneath checks and cracks. These cracks that develop should not be ignored, but instead should be treated fairly soon after they form so that the wood is sealed against water intrusion — preferably before much damage occurs. On new construction, plan on a maintenance coat one or two years after building and staining is complete, just to handle the new checks and cracks that inevitably develop soon after construction. Performing maintenance on time can be the difference between a simple maintenance coat and a full restain job. In general, even the best stains used on logs will need to be maintained every three to five years.

Real-Life Examples of Water Vapor Pressure and Breathability

The back-pressure damage from expanding water vapor is most often seen on the upper curvatures of logs that get very hot in direct sunlight. You can see this damage on many log homes if you look for peeling — especially along the edges of unsealed checks and cracks. In the picture below, you see a piece of red cedar that was stained with two different stains and left outside to weather. As 18 months went by, the wood cracked as it expanded and contracted, starting at the unstained middle strip where the unprotected wood started to crack very quickly. The cracks split the stains and allowed more liquid water into the wood. Note how the stains started to peel along the edges of the cracks where the back pressure from the water vapor was strongest.

Did you notice that one of the below stains was better than the other? Both were premium alkyd stains, but the one on the left was designed for general use. It is so hard and brittle that it can’t handle the movement of the wood very well, so it cracks and peels a lot. On the right side is a much more flexible alkyd stain (an early version of Sashco’s Transformation Stain® Log and Timber) that is able to move with the wood much better. As a result, the peeling damage from the cracking wood and water absorption/evaporation is much less pronounced.


Microcracks lead to peeling, as shown here. 



See For Yourself

The following panels show how differences in formulation (including elasticity) will perform when exposed to normal weathering.

Hard vs. Soft Oil Stains This exposure panel shows how a harder oil log stain (left) compares to the much softer, more flexible Transformation Stain® Log and Timber (right) after 24 months’ exposure. For oil-based stains, both are performing fairly well. Hard vs. Soft alkyd #2
Non-drying Oil vs. Flexible Drying Oil This panel shows a non-drying oil stain (left) vs. Transformation Stain®Log and Timber (right) after 24 months exposure. Although the non-drying oils have superb breathability, they simply don’t last, and as mentioned earlier, will keep sealants (and some future stains) from adhering properly.  Non-Drying vs Transformation
Eroding Alkyd Stains Let’s compare two different eroding alkyd stains. These don’t keep water out of the wood, so the wood cracks a bit. Still, they are extremely breathable, and keep their color and UV protection at the surface. Transformation Siding and Trim is on the right.Eroding Alkyds - TRW-1



Hard Acrylic vs. Elastic Acrylic An unusually hard acrylic stain (right) alongside Capture® with Cascade® (left). Both were exposed for 18 months. The hard acrylic cracked and peeled profusely. Breathability hardly matters for that stain. On the Capture®/Cascade® side, there is nearly no damage because they kept water out. Even where there are cracks in the wood, peeling has not started yet because Capture® and Cascade® are still very breathable. WT_vs_W15_CabotSPF



Typical Acrylic Here we see a common acrylic stain (right) versus Sashco’s Capture® and Cascade® stain system (left), exposed for 18 months. Note that on the right, the water getting into the wood has cracked and aged the wood, as well as the stain, but on the left side, with hyperelastic Capture®, the stain is still looking very good. CH_vs_W53_TimberEdgeNaturesEdge




Why Paint is a Bad Idea 

We’ve just discussed that paint is very breathable. So why not just paint a log home?


It’s true that paint lasts longer, but it’s also true that paint hides developing problems. Let’s take a closer look.


Note the blue tape on these logs. Those all mark areas of rotten wood. Before they knew it, they were digging out the entire corner of that house

The home above is a perfect example of paint hiding developing problems. From the outside, everything looked to be in pretty good shape…until the contractor started tapping on the logs. Before they knew it, an entire corner of the home had to be replaced. Nearly $100,000 later, the home was repaired. The homeowners were happy to have a semi-transparent stain applied this time.


With a semi-transparent stain, you can see water damage beginning (as shown in the photo above). With paint, all of that is hidden, often until it’s too late.


With all this talk of water damaging log and timber structures, we need to remember that good building design plays a key role in keeping water off the logs and timbers too. Foundations that are at least 18” above the ground, gutters and downspouts, and wider eaves will all help keep water out of a log home.


So, how important is breathability? Well, it is important that a stain or coating that will be used on exterior wood has enough breathability that it will minimize or eliminate any damage from moisture escaping the wood. A high-performance log stain will meet this need. But as shown, it’s more important to keep out water to begin with — and that starts with a high-performance stain that can move with the wood, is applied properly, and then maintained regularly.
