End Grain

Why is it so Critical to Seal Exposed Ends of Log Homes?

Wood is a hygroscopic material, which means it naturally absorbs and releases moisture from the environment. Logs can safely absorb large quantities of water before reaching moisture content levels that will be inviting for decay fungi.

Some of the most vulnerable areas of a log home are the corner log ends. This is because the cross section end grain is exposed and the ends often stick out beyond the walls allowing sunlight, wind, rain, snow and ice to wear away the stain and expose bare wood.

The exposed end grain acts like small straws sucking water into the log, giving rot and decay an opportunity to start eating away the wood. In addition, wood cracks and checks are prone to start at the ends. If left unprotected long enough, log or log corner replacement may eventually be required.

Being aware of the susceptibility of log ends to weathering, rot and decay, we developed Log End Seal, a clear polymer finish that prevents water from penetrating into log ends and provides a layer of protection against log end damage. Although it is a sealer, Log End Seal is designed to allow moisture already in the wood to slowly escape. This helps reduce those large checks that often form on log ends.

What can you fit inside a log?A hollowed out piece of timber on your home might make a convenient storage space for sports equipment or toys, but it's a problem. Before you panic and list your home up on Zillow or Redfin, let's take a look at the situation.

How much decay have you found?

If it's not halfway deep through the log, or less than a couple of feet lengthwise, odds are it can be repaired easily. M-Balm and E-Wood from Perma-Chink Systems are specially formulated epoxies designed to repair decay and soft spots in homes.

The biggest threat to log homes is decay damage, caused by moisture-loving fungi. The three basic categories of wood-destroying fungi are soft rot, brown rot, and white rot. Preventing rot begins with eliminating as much contact as possible with moisture, which breeds fungi. The best prevention is using borate preservatives, which destroy wood fungi and protect against decay.

If you do discover decay in your logs during inspections, it can most likely be mitigated and eliminated without the need for a costly log replacement. If the decay does not exceed more than half the depth of the log, or only a few feet lengthwise, use M-Balm and E-Wood. 

E-Wood epoxy after hardening can be cut, sanded, and finished like real wood.

Every spring we get lots of calls about carpenter bees drilling into logs, fascia boards, eaves, decks and other unpainted wood surfaces. Carpenter bees are big black solitary bees that look similar to bumblebees but have bare, shiny backs whereas a bumblebee's back is hairy. Unlike honey bees that reproduce in hives, carpenter bees drill into wood in order to lay their eggs. Their holes are perfectly round and about 1/4 inch in diameter.

Although carpenter bees prefer hardwoods such as cedar, redwood, or cypress, they happily attack pine and most other species of wood. Even pressure treated wood is not immune from carpenter bee attack. As the bee drills into the wood, coarse sawdust may be seen coming out of the hole and piling up beneath the hole. Since it only takes a couple of hours for a carpenter bee to drill a hole a few inches deep, lots of holes can appear over a fairly short period of time.

Most carpenter bee activity occurs in early spring when male and female bees emerge after spending the winter in old nest tunnels. Once they have paired and mated the female bee drills into a suitable site while the male stays nearby to ward off intruders. Male carpenter bees often frighten people with their aggressive behavior but since they have no stinger they are essentially harmless. Females have a stinger but only use it if molested.

Once the initial hole is drilled through the surface, the bee will make a turn and excavate a tunnel along the grain of the wood. This tunnel, which may run for several inches, becomes the cavity where the female deposits her eggs. Several eggs are laid in individual chambers separated by plugs of pollen on which the larvae feed until they emerge as adults during the summer months. In addition to making new holes, carpenter bees also enlarge old tunnels. If left unattended for several years, serious damage to a wood member may result.

Pressure washing (also referred to power washing) is the function of using highly pressurized water to remove mildew, mold, dirt, pollen, UV graying, etc. You’ll hear different recommendations whether or not pressure washing your logs is the best cleaning method.

Generally speaking, pressure washing is the quickest and least expensive choice.

One fallacy is that you’re saturating and “damaging” your logs with water as a result of pressure washing. This simply isn’t true. On hard, sound, rot-free logs, you’re only introducing water into the top fibers of the wood.

What are the benefits of using a top quality finish on a log home?

ext4Whether you’re currently building your dream log home or simply checking off tasks on your annual home-maintenance “to do” list, we’re always looking for ways to skimp on expenses around the house. But when it comes to putting your best foot forward with a beautifully stained home that’s also protected from the exterior elements, you might want to think twice before being lured in by the lower price tag of a middle-of-the-road finishing product.

Think about it: Not only does a stain and finish define the aesthetic appeal of your log home, enhancing the striking beauty of the wood’s grain and natural color, but it serves as a shield for your home’s most precious building blocks – the logs. Because of this, it makes sense to spend the extra money upfront on a high-quality finish for your home. And, as it turns out, if you can swing the higher cost for the first application, you will save yourself oodles of cash over the lifetime of your log home.

What are the qualities to look for in a top quality log home finish?

To ensure a successful and long-lasting result, you’ll also need to consider factors like wood protection, maintenance and, of course, appearance.

Appearance: In addition to building a quality home, you want to build a beautiful home, which is why the finished appearance of your logs is so important. By spending a little bit more upfront, you’ll get a distinguished looking wood finish that will set your home apart from the rest.

Are you a DIY-er? Do you like handling home projects, going back and forth to the local hardware store for equipment you need? While Perma-Chink Systems pride ourselves in offering DIY-friendly products, along with a wealth of how-to articles, customer and technical support, some customers choose to hire a contractor.

Or sometimes you can't do it yourself. Time, ability, confidence (or you plain don't want to do it) usually makes the decision for you and you need to find a contractor. Specifically, a log home contractor. application and removal step by step guidea

Why a log home contactor? Would you entrust your car to a golf-cart mechanic? While similar in nature, there is a difference between the two. Log home contractors have experience dealing with the unique characteristics that come with a log and timber home. This experience will give you a better result than hiring a painting contractor. Not to mention the long-term relationship the contractors have with the product manufacturer.

Perma-Chink Systems offers an extensive referral list of log home contractors from coast to coast. Most of these contractors are self-employed and none are affiliated with Perma-Chink Systems, but they do have both experience and training in using our products on log and timber homes. Many of the contractors we've worked with for years, and we continually review our referall list to provide our customers with the best available contractors.

Two Steps and Four Questions

Step 1 – Get Smart

A very important first step before interviewing any contractor is to educate yourself. Perma-Chink Systems can help you better understand the steps and nuances of your project. You can attend one of our free homeowner workshops, read through our literature and application guides, or call one of our log home specialists to walk you through the process and related products. Better yet, go online and register for a private webinar with our experts. The more you know about your upcoming project, the better you can ask the right questions and understand the answers from the contractors. So please don’t overlook this important step!

MOBILE LOG CABINS (or PLUG & PLAY TRADITIONAL LOG HOME)
By Dan Waring, British Log Cabins
 
 
Mobile homes...Traditionally an ugly metal box, BLC have taken the parameters defining the mobile home and delivered a beautiful alternative LOG CABIN!
 
Developed in response to an increase in the popularity of ‘Log Cabin Holidays’ our Mobile Log Homes include everything. The entire building is prefabricated off site in our log building yard on a specially designed rolling chassis.

Log building as a construction method and art form has been around for centuries. It’s origins were in Eastern Europe and Scandinavia. As a trade it has a long established history. The often romanticized vision of a cozy, traditional log cabin in a holiday area is now a reality.
 
mala pattersonAfter graduating from college, the normal progression for most women is marriage. But, what is great, or even fun, about being normal? This neo-Laura Ingalls-Wilder, this Backwoods Barbie, embarked upon an adventure. I decided to build a log cabin!
 
I have had the pleasure of being around log cabins nearly my whole life. I grew up in my parents’ pine, D-shaped log cabin. They had a “turn-key” package; but we, mainly my father, ended up doing a lot of the work. Despite three children, pets, and fluctuating Alabama weather, their home has weathered nicely with little maintenance. Therefore, my parents are supportive of my log cabin, although they enjoy ribbing me about some comments I made when I was about ten years old.
 
I was ticked at my mother because she did not think that a black and silver waterbed (completed, of course) with a zebra bedspread was suitable décor for a ten year-old girl’s log bedroom. Thus, I declared that I would never have a house of wood. I vowed to have only wallpaper and paint in my house one day. (Never say never!)
 
Anyway, my adventure started when I found an ad for oak log cabin kits in a classified newspaper. Not wanting to be saddled with a large debt and realizing that I would be responsible for cleaning and maintaining the house, I decided to purchase the approximately 1,500 square-foot kit. The logs arrived safely and beautifully – Missouri oak heartwood dovetail logs.(Say that ten times fast!)
 
porchSince my kit consisted of only the perimeter wall logs, I drew the interior plans one Sunday afternoon; and Mom and I devised a plan that would allow me to “pay-as-I-go” and have the cabin completed and paid-off in three years. However, I did not realize how much I was going to be involved with the “hands-on” construction, and I never imagined how much I would learn to do and end up doing myself.

The Leroy Mountain project was in need of some help. Built in 2003 it had been coated with Sansin Classic. One product, one color had been used on everything- logs, trim, and deck. This resulted in a mono-tone appearance. A second and third coat had been applied over the years, without adequate preparation. On one wall it looked like the finish had not been stirred or mixed before applying. Time, sun and weather had degraded the exterior badly. It was sad to see such a beautiful home in this condition.
 
My first impression on seeing the house was “Whoa, what is that little gem doing here?” Large Doug Fir logs, scribed fit, three gables, two balconies, two dormers, two porches, hexagon great room and deck – all tucked in on a basic footprint of 32’ X 32’. This is not your typical Pennsylvania log home. The log kit was supplied by The Log Connection, British Columbia, Canada. As soon as I saw it I knew we could bring it back to better then new looking condition.

stains2What types of log home stains work the best?

So we have all this helpful information on the types of log home stains but which log home stain is the best? It is hard to say which one is the absolute best because there are many factors that ultimately decide how well or long a log home stain will perform. Some of these factors are:

  • What season the logs were cut (winter cut logs only)
  • Proper surface preparation
  • Environment surrounding building
  • Moisture content of logs

Of all these factors none is more important than proper surface preparation of the logs before applying a log home stain. If the surface of the logs has not been prepped properly none of these log home stains will perform as they state they will. This is why it is important to only hire a qualified log home restoration expert to work on your log home! They will have the knowledge and expertise to work with the products available in the current log home market. This will ensure your investment is protected well into the future.

While we can’t say which log home stain is the overall best, we can recommend which type of log home finishes we feel perform exceptionally well and keep maintenance costs down throughout the years. This only holds true if proper surface preparation is kept in mind before and during any finish or sealant application. In our opinion, film-forming, latex based waterborne log home finishes such as Perma-Chink Systems’ Lifeline is best bang for your buck!

While Perma-Chink Systems finishes aren't the cheapest out there they seem to require the least amount of maintenance based on our 25+ years of experience restoring log homes and log cabins of all sizes and shapes. They also offer an unmatched 5 year warranty on their log home stains when applied properly and maintained accordingly.
