Perma-Chink Systems, Inc
Log & Timber Home Care Experts
In the early 1980s Rich Dunstan, our founder and company president, had to come up with a company name. Although Perma-Chink Log Home Chinking was the only product manufactured at the time, he choose Perma-Chink Systems, Inc. The name was chosen because he had a vision of developing a full line of products to construct, clean, preserve, seal, finish and maintain the wood components of a log home. Over the years Rich has fulfilled his dream and Perma-Chink Systems, Inc. has become a systems company. No other log home related company offers the broad range of products that we do. However, this large product offering presents a challenge to our own salespeople. We expect them to achieve a high degree of expertise in a wide variety of different product lines. To reach this goal we devote hours of training so that they can knowledgably assist our customers.
When it comes to ordering sealants like our Perma-Chink® or Energy Seal™, there are two dimensions that you need to know in order to determine how much product you will need: the width and the cumulative length (linear feet) of the gaps or joints that you want to seal.
Although most people use brushes to apply our finish removers they can be applied with airless sprayers as long as you know what to do. Here is some information that will guide you in using airless spray equipment to apply both S-100™ and StripIt®.
Perma-Chink Systems offers wood preservatives designed to protect your home from insects and wood rot. Below are our Tech Tips for our preservatives, along with some general product knowledge on storing procedures.
Perma-Chink Systems namesake product, Perma-Chink, is the leading sealant for log homes. We've extended the same performance and quality of Perma-Chink in our other sealants, Energy Seal and Woodsman.
Below are our Tech Tips for all our sealants, including our Chink Paint, which provides an excellent solution to refresh old, but sealed, chinking.

Perma-Chink Systems have the best stains for log and timber homes. While we tend to call our stains "finishes," most consumers are used to the phrasing of "wood stain." Why the difference? The quick answer is that stains permeate the wood, while finishes form a film over the surface, protecting the wood. If you want to know more about the difference, our tips below can answer your questions.
The Tech Tips are grouped below by how our system works. Like most things in life, success is determined by a strong foundation. So the first section contains information on getting your log or timber home ready for the finish of your choosing. Following the surface prep section, we've consolidated information about our finishes for both exterior and interior. The final section is dedicated to known issues with log and timber homes that all homeowners have to deal with, regardless of which finish they choose.

In today's economy energy efficiency is a subject that most people are aware of including log home owners and those people contemplating the purchase of a log home. With this in mind we occasionally get asked about the R-value of our chinking and/or backing materials since many people assume that they provide some insulation value to the exterior walls. In point of fact, neither the Perma-Chink nor the backing material contributes any significant insulation value to a wall. What they do is eliminate outside air infiltration into the home. This has a much greater impact on the overall energy efficiency of a home than adding a minor amount of insulation to a wall.
Although there is some controversy regarding its cause, the most commonly held theory about the formation of mill glaze is that it is created on logs, siding and trim by heat and mechanical compression generated during a high speed milling process. The combination of compressed wood fibers and high temperatures that melt the sugars, cellulose, and other water-soluble extractives present in the wood end up forming a surface glaze.
