Shell-Guard

Borate-Glycol Wood Preservative

Shell-Guard provides the ultimate protection against insects and wood rot for your log home. This new generation of preservative combines the well-known effectiveness of borates with a glycol system that increases the penetration into the wood to enhance the action of the borate.

Shell-Guard is colorless and odorless. The glycols used are the same type as those found in many food and skin care products.

Shell-Guard is a concentrate that is mixed with an equal amount of water, then applied to bare wood with a brush or as a spray. Once in the wood, it will kill those insects that eat wood such as wood boring beetles and termites. It also kills the types of fungi that are responsible for rot and decay. Shell-Guard makes wood toxic to wood destroying organisms!

The best thing about Shell-Guard is that one application will last the life of your home as long as the exterior surfaces are maintained with a quality, water resistant stain such as Lifeline.

Preservatives Reviews

We had an infestation of powder post beetles on one side of our home. We were told by our neighbor that Perma-Chink Systems had a preservative that would take care of it. We applied the Shell Guard Concentrate and had to wait a couple weeks for it to dry before staining. We noticed over the next several months that it had to be working since we didn't see as much dust around the holes. It has been a year now and everything is great! I would recommend this product to anyone if they are having issues with insects.

My girlfriend and I bought a foreclosed conventional home that had major water damage in the master bedroom area. I asked around for different products that would help stop the rot from continuing and was given Perma-Chinks number. We purchased the Shell Guard Concentrate and applied to the entire crawl space. We then also removed all the paneling and cardboard ceiling squares (home built in 1974) and applied the Shell Guard there as well. This product is easy to use and no worries around your pets and kids. I have recommended this to many of my friends and feel this is something any household can use in preventing rot. Thank you.

For the cost and ease of application you’d be nuts not to use RTU. It’s like an additional insurance policy for your log home. You pour the product into a garden sprayer and saturate the logs. That’s it! It took me 3 hours to do my entire house. This is my second log home, I used RTU on my other home and never had any rot or insect issues. Do yourself a favor, don’t skip this extra step!

Powder Post Beetles dead! I built a porch on my home 3 years ago. On the porch, I built cabinets using old barn wood that I had heated to kill bugs. A year or two later, I started seeing little piles of sawdust on my counter tops. Sunday, I mixed up some Armor Guard and water and put it into a Cajun Injector that I use to marinade meat and injected the solution into those tiny holes. It really went into the wood well in some areas. I guess by injecting the solution I got it right to their food source, they ate it, and died!
