The Log Home Neighborhood

An online log home community for log home enthusiasts.

We have a log home that has been erected for 4+ years. The logs were down 1-2 years previous to the build. Shrinkage and movement has seem to stopped. The home is coved and chink less. But we still have air movement predominately in the corner notches but also in the odd horizontal line. It was built with the standard foam gaskets between logs.

I would like to seal the home as best as I can to help with rocketing heating costs. Has anyone used just a clear or coloured sealant on all the joints instead of thicker chink product lines? What product as worked? I have looked at DAP elastomeric products and other flexible type sealants. I really like the look of chinking but the boss doesn't. Should I seal the exterior and the interior?  Any problems with using a chalk instead of chinking?

Any thoughts will be appreciated.

Thanks All

Most manufactured "chinkless" style homes will require caulking eventually. Looks like your eventually has arrived. :-) You don't always have to seal every single horizontal line at the same time, but it's something you'll probably have to do over time. Internal gaskets are great and do part of the job, but the wood usually shrinks and moves too much for the internal gasket to handle, requiring caulking. The good news is that there are products out there that will help you maintain the chinkless look while also sealing things up (both of which will make the boss happy. :-) ).

This time of year, unless you have weather above 40 degrees consistently, I'd say focus on sealing the interior. You can work on the exterior when warmer weather comes back in the spring time. Most caulks require temps between 40 and 90 to cure properly. Going outside of those temps can cause problems.

Check the caulk you choose for a max. joint size. Most will give it in the technical data sheet or application info available on their website. For instance, our Conceal textured caulk can be used in joints up to 2" wide, so you can use it on pretty much any joint around the home unless it's a really wide chink joint. It's textured and comes in colors that match the most popular stain colors, so you can maintain that "chinkless" look while sealing things up. There are other textured caulks out there and each will have a different max. joint size. I'd be happy to send you a color card for our product so you can see what I'm talking about. It has pieces of the actual product on it so you can see the color and the texture.

All that to say - yes, you'll have to seal it, but it will all be for the better in the end. You'll keep moisture and bugs out, not to mention those drafts that make the heating bills rather expensive.

Here's a link to info on Conceal on our website: http://www.sashco.com/log/products-conceal.html

Hope you're enjoying the holiday season & have a very Merry Christmas!

Hi Thanks for the reply

Merry Christmas to you too!

Is Lexel ($$$) a product of yours? I have some and thought it may be the answer

I used Sunfast (General Paint Canada) (performing well) for my primary coating. Thought I would chalk with a product that I could then re coat .

The home does not receive rain or snow on the exterior logs only the posts that support the wrap around concrete deck 

Yes, Lexel is a product of ours. Yes, it costs more than your DAPs of the world, but it usually lasts longer, too. :-) It will work for your purposes, but it is more expensive than Conceal and won't blend in as well. 

I don't know the Sunfast brand well, but as long as it's free of waxes, silicone and other things like that, you should be OK to use any of our caulking products with it, and then stain over top down the line when it's time to do stain maintenance.

Your situation is one that we at Log Home Finishing LLC hear about over and over, a chinkless home which really needs to be chinked.  It becomes obvious after about 4 years like in your situation that what was sold as a chinkless home really isn't a chinkless home.  We normally chink the chinkless homes with Sashco Conceal 'Textured Caulk'.  DAP caulk is one of the caulks that we spend a lot of time cutting out after people make the mistake of using this wrong product to seal their logs.

Where is your home located?  This forum also allows you to upload photos which are very helpful in answering your questions.  Do you have photos?

Here is an example of a chinkless home which needed chinking this year in Colorado:

Hopefully these pictures work

We have complete wrap around deck so rain and snow never touch the walls

We live in the interior of B.C. I have a clear product call Lexel here that I was going to try

I used a Canadian product called Sunfast for the exterior/interior and so far has performed very well even on the posts and railings that see weather

Merry Christmas

Very beautiful!  After reviewing the photos I would recommend more traditional chinking for interior and exterior on all log joints.  First use backer rod or grip strip as a backer, and then Sashco Log Jam chinking.  We use the Conceal textured caulk if it's smaller lines like 1/2" or less.  Your chink lines on 12"+ Sweedish Cope logs would be an average of about 1".  Anything over 1" chink lines and I always use Log Jam.
