Every great story starts by setting a scene, right? Who are we to break tradition?
Picture this: you’re on a job site, the logs are thirstier than expected, the color isn’t quite right because the homeowner suddenly got tone anxiety, and the nearest dealer is two hours away. Nightmare, right? That exact scenario sparked the idea for Flex Tint stain system.
Back in 2010, it all began as a humble experiment to give pros the flexibility to mix stains on the job (classic beginnings for any great success story). We asked ourselves, “What if we could put pigment in a can?” Simple idea. Complicated execution. Contractors were spending more time scraping and stirring than actually staining, always chasing the perfect mix and color. So, the idea was shelved, for a while.
Then, at one fateful Zero Failures, we were talking shop with contractors telling us their real-world headaches. The best ideas often emerge from the most challenging problems.
Stories poured out. Different voices, same scenario. They were running out of stain mid-job, unpredictable wood, even more unpredictable homeowners suddenly falling in love with, or freaking out about, a color (hint: it’s usually the wife). Listening to these experiences was eye-opening.

Mark Nelson, now a Zero Failures instructor, shared a story that became a hallmark moment. Mid-job in Wyoming, he realized he was two gallons short. Without a fix, his crew would have been idle for about three days, costing the company about $10,000 in labor and lodging. Luckily, Sashco overnighted the extra stain and saved the day. But that moment planted a question in our minds. What if contractors could handle surprises like this themselves, with no stress and no extra costs?
The answer? Cartridges. We make caulk. We know cartridges! That conversation brought Flex Tint back into focus, now with a real purpose to solve these recurring problems right on-site.
And just like that (cue the triumphant music) Flex Tint stain system was born. If only it were that simple. Flex Tint didn’t come without labor pains, but we knew pigment cartridges would give contractors unprecedented control. Need a touch darker here, a little lighter there? No problem. Running low? Ship a small cartridge instead of a giant pail. It’s like having a mini paint store on your trailer.
Every detail, from cartridge sizes to color options to neutral base quantities, is designed to make life easier for contractors (and happier homeowners). Practical. Reliable. And yes, even a little fun to use.
One of our favorite success stories came from the crew at Knaughty Log Restoration. They were restoring a massive log home when the homeowner suddenly changed their mind about color mid-job.
“We were sweating bullets,” the foreman said. “If we’d already mixed 100 gallons of the wrong color, we’d have been out about seven grand. Flex Tint literally saved our bacon. We adjusted the color right there on-site, no wasted stain, no delays, no downtime. That kind of flexibility makes all the difference.”
Stories like that are what make innovation worth it. The real-world wins that keep jobs on schedule and crews working smarter, not harder.
So, there you have it, the tale of Flex Tint. Thanks to open-ears, open-minds, innovation, and a whole lot of keepin’ on keepin’ on, there’s now a solution to the moments that used to slow applicators down, stress you out, or make you wish you had a magic wand on-site (or perhaps disappearing powers). Now, you can handle surprises, fine-tune colors, and keep the job moving without breaking a sweat. Contractors provide better service, homeowners get just the color they imagined, and everyone walks away happier. Who knows? Maybe one day we’ll whip up the sequel about that hilarious time the wife had a change of heart right in the middle of the stain! But that’s a tale for another day. Stay tuned.
You’ve heard the stories, now see the numbers. Use our Flex Tint ROI Calculator to find out just how much time and money you could save on your next project.
Answer a few quick questions about your crew, hourly rate, and the hiccups that happen on real jobs (like color changes, late stain deliveries, or waiting on product) and see how Flex Tint might just save your bacon, too!
When it comes to protecting and beautifying your log home, Sashco isn’t just another stain on the market — it’s the high-performance choice for serious log lovers. With industry-leading products like Capture, Cascade, and Transformation, Sashco combines cutting-edge technology and rugged durability to keep your logs looking stunning and standing strong year after year. Whether you’re chasing that perfect finish or just want to avoid the heartbreak of costly repairs, Sashco’s got your back. Because your log home deserves more than “good enough,” it deserves Sashco. Made for logs. Made to last. Made to make your neighbors jealous.
Let’s face it, if you own, build, or work on a log home, you’re not just navigating the complexities of wood (which is finicky enough). You’re going head-to-head with the elements. That beautiful log home? It’s under constant attack from moisture, insects, fungi, and good old Father Time.
In fact, here’s the hard truth. There are only two kinds of wood: wood that’s already rotten, and wood that’s waiting for its turn. Grim? A little. Preventable? Absolutely! If you’re using the right tools.
Enter, borates.
So grab a coffee, and let’s walk through what you actually need to know to keep that gorgeous log structure protected from bugs and rot.
Borates are the silent-but-deadly type. They are harmless to you, but a nightmare for pests. Technically, they’re mineral salts derived from boron, a natural element found in soil, water, plants, and even inside your body.
They’re non-toxic to humans and pets (about as dangerous as table salt), but absolutely devastating to the pests that love to snack on your log home, think termites, powder-post beetles, old house borers, and the main villain, fungi that cause wood rot.
Unlike contact killers, borates work smarter. Insects and fungi must ingest the treated wood. Once they do, borates disrupt their systems and essentially starve them. It’s nature’s very own pest control (pretty clever, eh?).
Note: Because carpenter bees don’t eat the wood—they just chew and spit—it won’t affect them. You’ll need a different strategy for those guys. Here are tips on how to deal with carpenter bees.

Now let’s talk about the application. The go-to combo for surface and internal protection is Board Defense and Cobra Borate Rods. Used together, they offer layered defense, both externally and internally.
Board Defense is a borate powder concentrate made from disodium octaborate tetrahydrate (sounds like a villain from a Marvel movie, but it’s actually the same active ingredient you’d find in Tim-Bor). Use it on any bare wood you want to protect, everywhere from framing and attics to crawlspaces and plumbing chases — and logs, of course. It’s ideal for both new builds and maintenance on existing structures.
And yes, rod size does matter. Use the right diameter and length for your application. We’ve got charts for that. Don’t wing it.

Borates are versatile, but they really earn their keep in specific problem areas. Let’s take a look at where they work best.
Replacing rotten logs? Don’t cut corners. Soak new logs in a borate solution, treat checks, and insert rods (bonus points for pressure-treated logs with borates already infused, great for warranties).
Want to keep the classic look and gray patina? Stains are off the table, but borates aren’t. Treat annually, then finish with a matte clear coat (like Cascade®) for added protection. (Disclaimer because lawyers: in general, Sashco would never recommend just a clear coat on a surface. But, in these historic homes where the historic society says you can’t, any protection is better than none.)
Before you button up walls or cabinets, dust a little borate powder into hidden spaces. Pests like ants and roaches groom themselves (gross, but helpful), so crawling through the powder eventually knocks them out.
Beetles in barn wood? Inject borate solution directly into exit holes with a ketchup bottle or marinade injector. Once they eat it, bam—bugs gone.
Outdoor railings are prone to checks and rot. Drill in Cobra™ Rods, coat with borate solution, and add weep holes so moisture doesn’t stick around. Future you will be grateful.
Borates are one of the safest, most affordable, and most effective ways to protect your log home from rot and bugs. Products like Board Defense are perfect for surface treatments. They’re easy to apply and highly effective when used on bare wood. For deeper, long-term protection, Cobra Borate Rods are your best friend, working from the inside out to guard against decay where moisture tends to sneak in.
This dynamic duo isn’t just for one type of job, either. Whether you’re dealing with antique log homes, new construction, railing systems, or replacing damaged logs, borates have a place in the plan. If you’re in the log home world—contractor or homeowner—don’t overlook the power of these small but mighty tools. They’re not flashy, but they’re foundational. And sometimes, quiet protection is the best kind.
Just don’t forget that all of this works best when it’s paired with solid log home maintenance.
Borates are excellent backup, but they’re not bulletproof. The real MVP is still a well-maintained stain and sealant system. That outer shell keeps water out and borates in. Without it? You’re only doing half the job. Make annual maintenance checks part of the routine. If you’re a contractor, offer it to your clients. Catch rot early. Stay off ladders later.

Whether you’re a homeowner looking to protect your investment or a contractor wanting to offer added value to clients, we can help you create a smart, effective maintenance strategy that keeps your logs looking great for years to come.

You may have spotted a crack along the caulk line or noticed some chinking starting to pull away. Leave the paper bag for lunch. There’s no need to panic, log home chinking and caulking repairs are completely normal.
Logs shift and settle with the seasons, which means your sealants go through a lot. Imagine constant exposure to sun, wind, rain, and even a curious bird or two. With all that pressure, a few tears may be expected. The good news? With the right info and a little elbow grease, most of these issues are easy DIY fixes. Let’s walk through what to look for, how to repair it, and how to keep your log home sealed up tight for the long haul.
Start with a simple walk-around inspection (bonus points if you have coffee in hand). Especially after a rough winter or a prolonged period of heat, inspect those sun-exposed and moisture-prone areas. Keep an eye out for:
Tiny issues can turn into big problems fast, so catch ‘em early and save yourself the headache later (use this handy checklist to help guide you).
Not all sealant issues are created equal. Knowing the difference between adhesive and cohesive tears helps you fix it the right way.


Either way, don’t stress. Both are fixable with the same basic repair approach.
Log homes are a different animal compared to standard stick-frame homes. The logs breathe, move, swell, and shrink with the weather. That natural movement puts stress on joints and sealants over time. Think of it like trying to stretch a rubber band around a growing tree. Without the right support and flexibility, something’s gonna give.
Now that you understand the whys of sealant tears, let’s get to the nitty-gritty. How do you fix it? Whether you’re dealing with adhesive tears (pulling away) or cohesive tearing, the repair process is almost the same. Here’s how to do it the right way:
For adhesive tears: Use a utility knife, scraper, or oscillating tool to remove the bad stuff cleanly. Make sure to scrape off any leftover gunk so the new sealant has a clean surface to stick to.
For cohesive tears: As long as you’ve used either a Sashco product or another compatible sealant that will stick to itself, simply use a utility knife to relieve the pressure. No need to cut everything out. You just want that tear to not be stretched to the limit anymore. (Check with us about compatibility to be sure before you go this route.)
Use a log-home-safe cleaner like CPR Log Cleaner or old-reliable itself, soapy water. Rinse thoroughly and let it dry completely. This step is not optional—trust us.
If it’s deeper than ¼» and no backer rod is already in there, time to insert a backer rod. It keeps the sealant from bonding to the bottom of the joint (which you don’t want) and lets it move more easily with the logs.

Use something made for log homes. Sashco’s Conceal and Log Builder are solid picks and will stick to themselves, if that’s what you’re repairing. (Log Jam, too!) All of these products are flexible and built to move with your home. Load up your caulk gun and run a smooth bead along the joint. On cohesive repairs, go right over top of the tear, making sure to extend the new bead past the torn area to cover it completely.
Use a spatula, trowel, spoon, or damp foam brush to smooth it out and press it into place. Don’t skip it! This step ensures solid contact between the sealant and the logs.
Avoid water, rain, or freezing temps for the first few days after application. No pressure washing just yet!
We get it. It’s tempting to slap some fresh caulk over old sealant and call it good. But resist the urge. A few things to avoid:
Shortcuts here can lead to more expensive repairs later. Take the extra 15 minutes, it’s worth it.
Most minor issues? Totally DIY. But if you see signs of rot, water damage, mold, or large-scale sealant failure, it’s time to call in backup. Use Sashco’s contractor locator to find a trusted pro near you.
Owning a log home is kind of like being in a relationship. Sure, it takes attention, care, the occasional check-in, and knowing when to smooth things over (couldn’t resist a cheesy tooling pun now could we?) But when problems pop up, you don’t have to panic or break the bank. With a free weekend and the right products, you can tackle small sealant repairs like a pro and feel confident in the upkeep of your beautiful home.

You laid down your bead, smoothed it out, stepped back to admire it, and bam, there it is. A blasted blister. That dang little bubble that shows up right when you’re trying to wrap up (end of the day, over budget, thumb still throbbing from that ladder incident. Classic. We’ve all been there). First things first, it’s not the end of the world. It happens every now and again, and it’s easy to fix.
Let’s walk through why it happens, what to do about it, and how to avoid it next time.
Blisters in caulking and chinking usually show up when moisture vapor trapped underneath tries to escape, but the surface has already skinned over. That trapped moisture pushes up, and boom, a bubble.
It’s more likely to happen when:
Caulk dries from the outside in. If the surface skins over too fast (like when you’re working in the sun or on a hot, damp surface), that moisture gets trapped and pushes up. That’s your blister. It’s not a mess-up, just moisture trapped where it shouldn’t be.

Caulking or chinking dries from the outside in. If the surface stings over too fast, moisture gets trapped and pushes up.
If you’ve got some flexibility in the job timing, shoot for:
Still, sometimes the conditions just aren’t ideal. That’s life. The good news is that fixing a blister is simple.
You’ve got two scenarios: the caulk is dry, or it’s still curing. Here’s what to do for both.
That’s it. Nothing fancy.
Easy fix. Looks clean, works like it should.
Blisters happen. No big deal. Now you know how to fix them without fuss. If you want more solid tips or straightforward info for the jobsite, check out the Place for Pros on our website. It’s definitely worth a look and packed full of practical stuff that’s actually useful out there.

Any contractor worth their salt knows this business is a constant balancing act. You are always up against tight budgets, the pressure of clients who demand solid work without breaking the bank, and deadlines that never quit.
It’s tempting to pinch pennies on building materials to keep costs down. Anyone who has been in the business for a long time, though, knows that cheap materials often end up costing more in the long run.
When you really understand the secret to successful business and start to wrap your head around the fact that real value comes from looking past the sticker price and choosing materials built to last, you know you’re beginning to think more like a savvy business guy and less like a fly-by-night contractor. Understanding that investing in premium building materials upfront cuts down on callbacks, saves time, and keeps your projects running smoothly from start to finish is smart and it’s solid business practice.
Here’s why spending a little more on quality building materials puts money back in your pocket and keeps your business running like a well-oiled machine.
Cheap materials might seem like a win upfront, but they rarely stand up over time. If you love fixing leaks, peeling stains, or worse, rotting wood (and taking a lot of Advil), then yes, go on the cheap.
For the rest who understand this business, you know callbacks aren’t just a hit to your wallet, they mess up your schedule and your reputation too. The best contractors understand that using premium, trusted materials means fewer surprises and a job done right the first time.
Quality building materials apply smoothly and are more predictable, letting your crew finish jobs without guesswork. The faster you wrap, the sooner you move to the next project, keeping clients happy and deadlines manageable (not to mention putting to death those dreaded “can you fix this real quick?” calls after hours. Yep, you’ll thank us later).
When materials perform as promised, you avoid costly warranty claims and the stress that comes with them. Reliable products mean fewer headaches, more peace of mind and fewer awkward “uh yeah, so about that job we did…” phone calls.
Seasoned contractors know full retail isn’t the only option. They build relationships with suppliers and score volume discounts, seasonal deals, or bundle pricing that keeps quality high without slashing your margins.
Here’s the hard truth: the lowest-priced stuff often means extra labor, more prep, and sometimes redoing the whole job. Considering it costs at least $600 per day to have a crew of three guys go back to a job, it makes sense to avoid going back in the first place by using better products.


Cheap building materials often mean more costly repairs and work in the long run.
When you tally it up, spending a bit more on quality from the start almost always makes better financial sense. If you think premium building materials are expensive, try explaining to a client why their home looks 10-years old after one winter. It’s just not worth it!
Choosing the right materials isn’t just about performance. It’s about protecting your business. Sashco’s quality products like sealants, stains, and preservatives safeguard your reputation, streamline your workflow, and boost your profits. Cutting corners on building materials just means more headaches later, and no one’s got time for that.
You don’t get paid for fixing mistakes, so invest in materials that let you finish the job and move on. We’re here backing your trade with products that actually work, so you can get the job done right the first time, every time.
At Sashco, we often talk about «Zero Failures» and «doing it right the first time,» but behind all of that is something even more important. Behind the talk, we genuinely care. And not in a half-hearted, «have a nice day» kind of way. We mean the sleeves-rolled-up, boots-on-the-ground sort of care.
We care about the homes and buildings you work on. We care about the customers you serve. And yes, we care about the work you do every single day to get the job done well.
So what does that look like?
It means taking the time to develop products that not only work in a lab but also work effectively in the real world. In the heat, the cold, the rain, and on the job sites where timelines are tight and quality still matters. It means answering the phone when you call and troubleshooting alongside you when things don’t go as planned. It means giving you and each other honest answers, even if they’re not always the easy ones.
We’re a company full of real people who get excited about log homes, caulking, stain, and sealants (we know, it’s a little nerdy, but we’re into it. Always have been, and always will be.). What we’re really into, though, is supporting the trades. We know how hard you work. We see the pride you take in doing things right. And we’re right there with you.
Caring isn’t just a value we stick on a wall—it’s what guides our decisions, shapes our culture, and defines the way we do business. It’s why we invest in training, why we’re constantly testing and improving, and why we’d rather take an extra step than cut a corner.
Because at the end of the day, if you’re going to stand behind your work (and our brand), we want to be the ones that are standing right there with you.

The best log finishing contractors build long-term relationships, not just one-time jobs. And that starts with helping your customers stay ahead of log home maintenance before their place looks like it’s been through the wringer. Here’s how to build a no-BS log home maintenance reminder system that keeps your calendar full, your customers happy, and their homes protected.
Don’t let the homeowner think “stain = done for life.” Tell them the truth. Log homes are high-maintenance, beautiful beasts. Let them know that even with top-tier Sashco stains and sealants (like Capture + Cascade or Transformation), regular inspections are key, and recoats aren’t optional if they want to avoid big repairs. Tell them upfront what to expect. It’s also a great idea to leave them with a care guide that contains all the necessary information, like:
If you’ve done a good job and they have your info handy, they’ll call you instead of going to someone else when it’s time for maintenance.
When setting up your log maintenance reminder system, every house you touch should be added to your files (seriously). Minimum details should include:
Set reminders for yourself. Two years. Three years. Five years. Figure out what works for the stain system and the exposure, then come up with a plan to follow up and snag that repeat business everyone wants!

Nobody wants to hear from you when their stain is peeling off, and they’re facing a $10k+ re-do. Be the guy who reaches out when all it takes is a maintenance coat. Little things go a long way, a simple call or text saying, “Hey, it’s [your name]. I hope you’re doing well! It’s been three years. How’s that south wall looking? Need me to take a look?” Or, offer a low-cost inspection and wash. That small job today could save your customer a big expense later, and it keeps your name at the top of their list.
You don’t need fancy software. Use Google Calendar. A spreadsheet. A paper planner. The point is, don’t rely on memory. Set your maintenance reminders so you follow up on time, every time.
When you check in, focus on helping them avoid costly problems rather than selling them something they don’t need. Talk to them in a way that makes sense to them. Let them know that getting a log home maintenance coat now is way cheaper than having to do a full re-stain down the line. Plus, it’s a heck of a lot easier to stay on top of things than to play catch-up later! That’s the kind of contractor they’ll trust, and that’s how you build repeat business.
Let’s be real. Sashco stains and finishes are top-of-the-line, but nothing lasts forever on a log home without maintenance. Be the contractor who helps customers stay ahead of the game. You’ll keep them happy, and you’ll build steady work that fills your schedule so you can chase cold beer, not cold leads.
When it comes to restoring log homes, few things are as rewarding as seeing history preserved and beauty brought back to life. That’s exactly what Rocky Ridge Log Restoration
is all about. Founded in June 2024, this emerging company has already made a significant impact with its commitment to craftsmanship and quality. We caught up with the team behind Rocky Ridge to learn more about how they got started, what drives their passion, and the tips they have for others in the trade. Here’s what they had to say.

A: “Rocky Ridge Log Restoration started in June 2024. The venture began with a thought, and then I discovered the Zero Failures course at Sashco’s headquarters. I met a lot of amazing people, and the thought became a reality. At Rocky Ridge, we specialize in all aspects of log homes, but we mainly focus on rot repair, blasting, staining, and some chinking.”
A: “I am proud of all my projects! I take a lot of pride in my work. One of my jobs I take real pride in is the Fairmont Jasper Park Lodge job, as it is a massive resort that brings in people from all over the world. I just find it so cool that I was able to work on those 100-year-old buildings (I would’ve never thought that a year ago when I first started this venture).”
A: “I am a big fan of the Sashco Capture/Cascade combination. They have created a variety of nice colors, and by layering them, you can discover even more beautiful combinations. The clear coat is honestly my favorite as it really finishes the whole restoration as the homes really shine and look brand new again!”

A: “A lot of these contractors have a lot more experience than I do, and I have learned a lot from them! One tip I would say, as I have been an employee for longer than I have been an employer, is to treat your employees great and they will put in great effort.”
A: “I really enjoy the transformation part of the house. Taking something that is worn out and needs attention, then transforming it into something beautiful, and ultimately having clients fall in love with their home again. That’s the best part of the job for me, and I get to see some pretty cool country and animals (bears)!”

This month we’re talking about building a nice butt. Nope, not that kind of butt. We mean butt-joints! Our very own log home expert, Paul Peebles is sharing some of his very best tips from the field to help you build a better butt-joint.
By Paul Peebles, Southeast Territory Manager (and log home owner who knows a thing or two about butt-joints)

No, not those butts — I mean butts in log homes, sometimes called butt-joints. These things cause a lot of trouble in the log home business because, too often, they are not designed correctly. That’s a problem because a poorly designed butt-joint can allow water and bugs into your home or behind the log siding, leading to rot and insect infestations. Yuck. After decades in the industry, I have found that close to 90% of water damage and rot are caused by leaky butt-joints. In most cases, when I have been called to a home that leaks water, I have found that it is the butt-joints that leaked — sometimes for years! The problem begins when builders butt two logs tightly together during construction. It looks tight, so it must be right, right? We all know that after a couple of years, the logs shrink, opening up those joints, and this lets in the water. Bad situation! One common indication that this has occurred is a little bit of daylight showing from inside the home. Follow these easy steps for effective butt-joint repair.
Place two blades into a circular saw (I use one of the small 5 ¼” rechargeable saws) and tighten the arbor. Make sure both blades are turning in the correct direction.
CAREFULLY plunge-cut the butt joint to open it up to ¼» wide from top to bottom. While doing this, try to keep the blades in, or on, the end of either the right or left log so you cut off the very end of one log or the other. Cut as deeply as you can into the log, but not down or up into the logs, or above or below them. For safety, I do not tighten my saw arbor completely. This sounds more dangerous, but it’s not. If you leave the arbor snug but not tight, the saw blades will spin on the arbor when the saw is in a bind and prevent the saw from kicking back.
Carefully clean out any checks that extend into the butt joint. I use a multi-tool with a cutting blade.
Add backer rod to the checks and to the gap between the logs and caulk. This configuration allows you to add the caulking INTO the gap between the logs and not just smeared ONTO it.
Caulk over top of the backer rod with a good quality sealant like Conceal® or Log Builder®. Be sure to tool it smoothly. If applied correctly, this will be a durable seal that should last darn close to forever.

Ready to stain? Don’t guess! Sample. Testing stain colors on your actual logs before committing ensures that you get the exact look you want and helps prevent “oops” moments later. Snag your free samples here.
