At Perma-Chink Systems, the ‘forts’ we build are designed to protect your home from the forces of nature: sunlight, wind, rain, dust, insects, and microorganisms. Our approach is built on a comprehensive system designed to safeguard your log home from the very beginning. Let’s take a closer look at how this protective system works.
Protection From The Start

For many years, we have emphasized that protecting your log or timber home begins with smart design. For example, many modern log home builders incorporate large roof overhangs and wide porches to help shield exterior walls from harmful UV radiation. Let your roof play an active role in protecting your walls.
Additionally, strategically planting trees to provide shade not only reduces energy consumption but also helps extend the life of your exterior finish system.

Protect From Insects and Wood Rot
Protecting your home from wood destroying insects is something we have also incorporated into our “fort” design. Bare wood logs or siding can be treated with anyone of our safe, borate-based wood preservatives such as Bora-Care®, PenaShield® and Tim-Bor®. These products are designed to provide a protective shell of defense for log homes.
If a wood-ingesting insect such as a termite or powder-post beetle passes through this protective barrier, they are in for quite a nasty surprise. The borates work to interrupt the insect’s natural digestive cycle, making it difficult – if not impossible – for the organism to process food. These products, while destructive to wood-ingesting insects, pose little danger to humans.

Protect From Ultraviolet Damage
Perma-Chink Systems offers a full line of stains with numerous color choices and benefits. For example, our stains such as Lifeline Ultra 7™, Ultra 2™, Accents™, and Exterior™ have ingredients designed to protect the wood surface from algae and fungi (mold). In addition, we also have ingredients that work to shield the lignin in your wood from photooxidation.
Lignin provides structure and support for the cell walls in wood. If it is destroyed by harmful ultraviolet (UV) radiation, then your coating could delaminate from the wall more easily. Furthermore, our stains also contain UV absorbers designed to filter out harmful radiation. Our colorants add another level of protection for your finish system. In general, darker tone stains provide a higher level of protection than lighter, honey-tone colors. Choosing a slightly darker tone will act as a shield to help protect your wood more completely and provide more longevity and less color shift.
The next defensive layer in our “fort” is the topcoat. Our Lifeline Advance Satin or Gloss topcoat serves several important functions. First, it creates a durable surface that makes it more difficult for dirt and debris to accumulate on the wood and sealant.
Second, it incorporates both UV absorbers and UV stabilizers. When UV light strikes a coating system, it can generate harmful free radicals that contribute to degradation. UV stabilizers work by neutralizing these free radicals, preventing further damage, while UV absorbers act as a shield, blocking harmful rays from penetrating deeper into the system. Finally, the topcoat helps maintain a sealed surface. By promoting water sheeting and faster evaporation, it reduces prolonged moisture exposure that can lead to the growth of microorganisms.

Protect With Industry-Leading Sealants
Our company was founded forty-five years ago to provide an innovative solution for chinking. At the time, many builders used concrete to fill the gaps between logs. As the logs naturally expanded and contracted over time, the rigid concrete would crack, creating openings that allowed water to penetrate and damage the wood structure. Perma-Chink®log home chinking seals the gaps between logs while remaining flexible, moving with your home to maintain a tight seal that keeps out water and insects.

For smaller joints of less than one inch, we also sell Energy Seal™ and Woodsman™ which are great products for sealing around windows and doors.
Protect With Cleaning Your Logs
Finally, regular cleaning of your home will help keep your home looking beautiful well into the future. Buildup of dirt and debris can provide a foothold for fungi and algae to grow, decreasing the longevity of your finish system. To aid in this annual cleaning, Perma-Chink provides a safe cleaner called Log Wash™ which does a fantastic job removing these unwanted contaminates from your log home.
PCS Family of Products
As you can see, we’ve built multiple layers of defense into your home’s protection. The forces of nature can be powerful and unforgiving, and over the years, we at Perma-Chink Systems have developed a deep respect for the damage they can cause. Let us put our decades of experience – and our fortress-building, or our system-building approach – to work for you.
