Outlast Q8 Log Oil is also formulated for the coating of freshly sawn ends of pressure-treated wood
products. Its use validates the warranty on Wolmanized and Outdoor wood. The best results are obtained if wood is immersed for 3 minutes or longer. If dipping is not possible, apply by brush, roller or spray to the point of refusal.
Great Preparation is the Key to Application Success!
Please Take Note:
Apply a Wood Preservative
Q8 Log Oil is an EPA approved wood preservative containing petroleum distillates and metallic equivalent of copper. There is no need to apply additional wood preservative (borate form) before applying Q8 Log Oil.
Have your logs been pre-treated with a wood preservative (borate form) at the factory or mill? Contact your log or siding provider if unsure.
What is a wood preservative?
Wood preservatives make wood toxic to wood damaging organisms such as powder post beetles, carpenter ants and fungi. Wood preservatives do not protect against non- wood eating insects such as Carpenter Bees and other wood drilling insects; only those that do ingest wood.

Caulk All Gaps and Checks
It is natural for wood to crack/check over time due to changing seasons, temperature and aging. Fill any spaces between the logs and upward facing cracks/checks in the wood. Fill all joints, cracks, and nail holes with a good quality acrylic latex caulk/filler created specifically for use with wood like Energy Seal or Check Mate 2.
Two options for caulking when applying Q8 Log Oil:
Curing time for Q8 Log Oil is always subject to the temperature, weather, and porosity of the wood. If there are many warm, dry days, Q8 Log Oil will cure in as little as two weeks. If there is humid or wet weather with lower temperatures in can take up to 4 weeks or more for Q8 Log Oil to cure properly.
Test the Stain
We always recommended performing a 1 coat color test to a clean, dry, bare area of the structure to which you are planning on applying Outlast Q8 Log Oil. Please Note: Q8 Log Oil is difficult to remove once it has been applied. Before doing a full application make sure that your color selection is correct, has a look you want, and a maintenance schedule you can manage. Wait 24 hours after applying a Q8 Log Oil sample, to make sure you are getting an accurate representation of color.
Q8 Log Oil contains an adequate level of mildewcide for most applications. LogFinish.com recommends adding MoldBuster Mildewcide to Q8 Log Oil for homes in very humid areas. We also recommend adding Moldbuster for homes located adjacent to rivers, streams or lakes as well as in forested locations where there is little sun or in hollows with little sun and poor air circulation.
Q8 Log Oil protects against wood eating insects like powder post beetles and termites. Q8 Log Oil does not protect against wood drilling insects like Carpenter Bee’s or Drilling Wasps. If these insects are an issue where your structure is located, LogFinish.com recommends adding NBS 30, an insect repellent with plant-based ingredients to your Q8 Log Oil application.
safety precautions on the label carefully before opening the container.
For wood already coated with Q8 Log Oil, apply one saturating maintenance coat. Please see the Outlast Q8 Log Oil Maintenance section for more details.
Weather Conditions During Application
Apply Outlast Q8 Log Oil
Regular maintenance and annual attention to your log home can save you money and time. Proper maintenance starts with visual inspection. Weather, exposure and altitude may vary, so maintenance may be needed sooner than later in some locations.
A general estimate for re-application with Outlast Q8 Log Oil is as follows: Apply first maintenance coat within 2-3 years of initial application, after that every 3-5 years as necessary. Note that walls with more exposure may need more frequent application than those not regularly exposed to the elements.
Maintenance coats of Q8 Log Oil should always be applied in one coat to the point of saturation. Please see Q8 Log Oil application for directions on how to apply.
Q8 Log Oil must be shipped via ground transportation due to its chemical formulation. All orders are shipped via FedEx. Q8 Log Oil is VOC compliant in all 50 states.
