From the Manufacturer:
Exposure to the elements can take a toll on your log home.
If you are not keen about upkeep, then you need to brace yourself for the high cost of restoration. Fortunately, there are no wood home or log cabin issues that cannot be addressed and even prevented with the right Outlast products. Q8 Log Oil is the most complete wood preservative and water repellent for exterior applications. Q8 is a waterproofing and water sealing alternative product that also provides translucent stain color with trans-oxide pigments that can never crack or peel off.
Outlast Q8 Log Oil is also one of the very few products available for consumer use that prevents decay, rot and attack by wood ingesting insects such as termites and powder post beetles. Highly effective against mold and mildew, the unique active ingredient in Outlast Q8 Log Oil is the ultimate deck stain and sealer alternative as well as an unsurpassed general-purpose exterior wood stain and wood preservative in one product.
A simple visual inspection of your cabin is enough to determine whether or not you need a full-blown restoration, or if your log home only needs additional TLC and maintenance. Ideally, you should do a visual inspection of your property at least twice a year in order to detect potential problems like termite tunnels and loss of water repellency which can lead to rot and decay. Gutters should be installed to deflect rain and sprinklers should be directed away from the sidewalls and foundation.
Simply stated, DRY WOOD DOES NOT DECAY. But how can you keep wood dry outdoors in the elements? Use Outlast Q8 Log Oil exterior wood stain and preservative. Make sure to avoid the temptation to waterproof wood outdoors, because these sealer treatments eventually peel and crack away enabling water penetration and further deterioration of the finish.
Even the most basic maintenance routine for your log home can help you avoid costly restoration work, which is why it pays to invest in the right water sealer/waterproofing alternative: Q8 Log Oil- penetrating log home stain, water repellent, wood preservative and all-around exterior wood protectant.

This is the stain! 12 years ago I bought my log house and took a WHOLE summer to refinish it.
Always listen to your gut! I didn't 12 years ago! I strpped, sanded, and Osborn brushed and then the sample stage happened. We ended up going with ultra 7 because the colors and samples just looked perfect. This is a great protect if your log home is in the shade. My north and west walls I never had to restrip. The others were every 3 years.
Q8 isn't a bright glossy finish that pops during your sample/color picking process. But.... over time you get to know your house and then reality sets in. Owning a log home that your proud of is a life style and alot of work! Q8 log oil takes the pain out of stripping off old stain and applying new strain. Staining is the fun part and very rewarding. With q8 log oil it's all rewarding. NO STRIPPING, NO BLENDING, NOTHING. JUST WASH WITH KLLEN START. let dry and apply. This is the go to for ALL wood, decks, fences, log siding, log homes, etc.
Very diy friendly. No lap marks, no streaks, etc. Just apply until the wood won't take no more. This stain is 100% the best out there.
Prep is the key. Don't judge it on wood that doesn't have open pores. Even log siding that has been crushed in the milling process isnt ready for stain.
Follow the instructions and you will be fine. Heck your kids can help. You literally can not mess this up.
Message my about this product.! Its my passion and I 100% stand behind it!
