The Original Elastic Log Home Chinking

Since 1981, Perma-Chink Log Home Sealant has proven itself on thousands of chinked and chinkless style homes to become the most widely applied chinking in the world. It's simply the best chinking by every measure: longevity, appearance, performance and ease of application.

Perma-Chink is a flexible, textured log home chinking that seals the open gaps between logs to eliminate heat loss and air infiltration. Even though it looks and feels like traditional mortar, it's not. Perma-Chink is a pure acrylic that adheres to logs and stretches to maintain a tight seal by following log movement.

Like all of our products, Perma-Chink is easy to apply and comes backed by the support of our knowledgeable, friendly staff. When you use Perma-Chink, professional advice is never more than a phone call away.

Application can be done by a homeowner or a professional contractor. We stock a full line of application accessories or can refer a professional applicator in your area.

five star S Wright in WA (01/25/17) - "SHORT & SWEET!!! I am reminded of the phrase---"How do you eat an elephant?" Simple---one bite at a time. My family and I built our log home and I was dreading the chinking process. No matter how much I sat and looked at the overall task---it simply seemed overwhelming, until I applied the "One bite at a time" technique, only in my case (one course of logs at a time). By breaking into small or SHORT sections I have been able to get ahead of the task and will complete at my leisure. The SWEET part is your product is superior and a pleasure to work with. Being water soluble makes it very easy to clean up. Can't get any better than that. Thanks Perma-Chink."

four half star  crose permachinkS Crose in KY (01/05/17) - "My husband and I are in the process of building and restoring a 1800's log home. We chose PermaChink for our logs. There is definitely a learning curve when it comes to applying this stuff, we taped off our logs to achieve a cleaner line, we used duck tape because it stuck better than painters tape. We wouldnt leave it on too long though - the chinking was applied over top a silver insulated backing material my husband purchased from our local big hardware store. I would recommend you purchase the large application gun for those tight spots. If I had it to do over again I would have chosen a different color besides sandstone, it has a tendancy to appear pinkish in certain lights. It takes a loooong time for the permachink to fully dry, we applied ours in August and it was still tacky 4 days later. The rep told us it would eventually dry even in super cold weather. Be careful not to put the stuff on too thick or in to wide gaps, because it will fall off, we have super wide gaps 6" in some logs and we had to apply thin coats over several days to keep it from drooping off. It also shrinks so be sure to smoosh it in good. I believe this is the best product on the market, but be sure to experiment with your colors and watch lots of tutorials. "

five star  Jo at Premier Painters, LLC in ID (10/23/15) - "We have been applying Perma-Chink chinking material for over 13 years on a commercial level. Its performance is outstanding. Its ease of application and cleanup when used properly makes it a great product to use. It is virtually maintenance free when cured. When applied correctly to close air leaks your cost is quickly recouped by stopping energy loss. We highly recommend this Perma-Chink product!"

four star  B Fey in WA (06/15/15) - "I first used Perma-Chink chinking on my log home 18 years ago and it’s still holding up great. I recently added an addition and needed more so I thought I would place the order online, it was easy and the shipping was way faster than I expected, pleased with my purchase!"

five star J Wilmes in TX (03/12/15) - "Perma-Chink is easy to apply and tool, and it looks great."

five star S Foster in PA (10/20/14) - "Perma-Chink is a great product, and it lasts forever!"

five star D Stevens in CO (09/13/14) - "Perma-Chink is great for sealing gaps between the logs to eliminate heat loss. Here in Colorado it can get quite cold! The Perma-Chink was relatively easy to apply and dried fast and was easy to clean up."

five star K Wright in NC (08/12/2014) - "We restored a hundred year plus cabin that has been in our family for generations. It was a lot of work but the results were worth it. Replacing all that mortar with Perma-Chink was the right decision. We couldn't be happier with the products and customer service we got from you folks there."

five star Jeff C in WI (06/30/14) - "Perma-Chink is an easy to apply and work sealer that gives the look of old mortar. I love that it is even easier to clean up...just soap and water! Great product and great colors!.

five star P Augustine in AK (04/12/2012) - "We love our Permachink! The color is perfect to accent our stain and topcoat, the texture matches my grandparents' cabins' mortar (which was very important to me!) and it was easy to apply. WIN, WIN, WIN!!!"

four half star F Wohl in ME (09/12/2011) - "We used Perma-Chink on our log home and I cannot believe the difference this has made with cutting down the drafts in my home especially in the winter months."
