Outlast Q8 Log Oil

OutlastTM Q8 Log Oil is an EPA registered exterior wood preservative specifically designed to control decay causing organisms  (and mold, termites, powder post beetles) in log homes and on wood siding.   It provides unsurpassed water repellency and sheer trans-oxide color with one coat coverage.  Q8 Log Oil is a totally non-film forming EXTERIOR treatment that will never crack or peel.  The trans-oxide pigment system provides excellent UV control that operates like a sunscreen to slow down graying of the wood and provide fade resistant color.  The solution soaks into the wood to provide protection, not just on the surface, but also deep into the wood cell structure.Q8 Log Oil offers unique flexibility in terms of application temperature ranges; log moisture content and delivery method. Q8 Log Oil meets all nationwide VOC requirements.

Surface Preparation Procedures:  The log or wood surface MUST be porous.  Remove mill glaze, dirt, mildew, or any film coatings before application.  Avoid sanding.  If sanding was required to remove a prior coating, re-open the pores of the wood with a chemical or detergent cleaner, thoroughly rinse and allow to dry as much as is possible (3-5 dry days) before application of Q8 Log Oil.

The absorption of Q8 Log Oil is directly related to the porosity of the wood, and more absorption of oil results in a better and longer lasting treatment. Because of this, new unseasoned wood will require more frequent applications than older dryer wood.  New wood usually benefits from an initial cleaning with bleach, water and TSP, followed by a brightener such as Oxo Wood Cleaner.  One quart of CTA's KleenStart granules diluted in 5-gallons of warm water will clean and brighten in one step.  Rinse thoroughly and allow to dry before application of Q8 Log Oil  A power washer at low pressure is an appropriate and time saving tool for wood surface preparation.

Before you start:  Test the color first. Full color and curing takes approximately 2 weeks.  Be aware that once Outlast Q8 Log Oil is applied and has soaked into the wood, it is permanent in the wood.  The surface will need to be re-freshed for color and water repellency, but the product inside cannot be removed.  If you want to change the color, be advised that solid colors are not possible in this system.  Semi-transparent shades are the only choices available.  If you have made an error in your color choice, you can power wash the surface color away and re-apply a different semi-transparentshade of Q8 Log Oil after the initial curing process. 

Spray, brush or roll:  Stir product well before use and stir occasionally during application to keep pigments suspended.  Intermix batches from different lot numbers AND intermix previously opened pails with factory sealed pails to ensure uniform color.  The fastest, easiest delivery method is by use of a pump-up type sprayer with a plastic or non-corrosive tip.  (Brass tip is NOT recommended.)  Airless spray applicators are not recommended due to excessive atomization and subsequent product loss.(Professionals may have airless equipment suitable for low-pressure applications, but do-it-yourselfers will have better results with the pump-up applicator.)  Apply as much liquid as the wood will absorb.  It is not necessary to "keep a wet edge" or to apply multiple coats or wet-on-wet coats. It is not necessary to clean out equipment until the job is finished, even if the job takes a week or more to complete!  When ready to do so, equipment can be cleaned with laundry detergent and water or mineral spirits if desired.

Weather conditions before during or after application:  Outlast Q8 Log Oil can be applied during a wide range of weather conditions.  Wet or cold logs/wood will not absorb as much product as dry/warm ones.  Below 50 degrees, Q8 Log Oil will become too thick to pump through a pump sprayer and may require hand brushing.  Streaking of pigment may result if it rains within 36 hours of treatment.  Simply re-spray the surface with more product, let it sit for 15 minutes and smooth out any streaks with a stiff paintbrush.

Longevity, re-applications:  Generally, it is recommended that new construction be re-treated within 24 months of the initial application.  Exactly when during the 24 months is determined by the moisture content of the log and/or the temperature/weather conditions at initial application.  Coverage needs to be in the 125 - 175 square feet per gallon range.  The more the better. Under application is far and away the primary cause of short treatment life.  However, only one coat at a time is recommended.  The water repellency in Outlast Q8 Log Oil builds quickly making it unfeasible to multi-coat until a period of years has elapsed.  (It becomes so water repellent, it repels itself!)  Additional applications should be applied as needed, usually every 4-8 years. 

Mildew:  Always sanitize the surface before application to remove all existing mildew spores.  (See Surface Preparation Procedures.)  However, be aware that mildew grows on dirt.  Logs are outside and subject to dirt.  Expect some mildew; especially on new logs that have not had the benefit of several soaking applications of Q8 Log Oil.  Mildew inhibiting additives are available for paints and stains and are recommended for use with Q8 Log Oil. See Mold-Buster additive.

Insects:  Outlast Q8 Log Oil is an EPA registered wood preservative containing copper 8 quinolinolate.  Copper 8 has very low mammalian toxicity and has been approved for use on wood that comes into incidental contact with food such as picnic tables, produce bins, etc.  Copper 8 is very toxic however, to a broad range of wood eating insects.  Termites and powder post beetles, for instance are killed by ingesting wood treated with copper 8 quinolinolate.  Some insects, however, such as carpenter bees, ladybugs, dirt daubers, etc, do NOT eat the wood.  These insects bore and/or nest, but do not eat the wood.  Additives such as NBS 30TM can be successfully mixed into the Q 8 Log Oil during application to inhibit crawling and nesting insects.  See your dealer for additional information.

Precautions:  Do not spray Outlast Q8 Log Oil on asphalt shingles because it will soften asphalt on contact.  Roof over spray or spills on asphalt driveways should be cleaned IMMEDIATELY with large volumes of a suitable detergent.  Review the safety precautions on the label carefully before opening the container.
