Sikkens Proluxe Cetol Log and Siding Preparation Instructions
• All wood surfaces must be thoroughly clean, dry and free of dirt, grease, grime, mildew, mill glaze and previous coatings before applying Proluxe Cetol Log & Siding Wood Finish.
• The best method to prepare vertical wood surfaces is to sand with 80-120 grit sandpaper. However, the following preparation may be used as an alternate to sanding.

Cleaning Recommendations:
1. Spray all wood surfaces with clean water, completely wetting the wood.
2. Generously apply a cleaning solution of four (4) ounces of 100% powdered Tri-Sodium Phosphate (TSP) or phosphate-free substitute with one (1) quart of liquid bleach and three (3) quarts of water to the wood surfaces with a garden sprayer or a heavy nap roller cover.
3. Let the solution dwell on the wood for 15-20 minutes as you scrub the surface with a hard bristle brush to help remove mill glaze or weathering. Do not allow solution to dry on the wood surface.
4. Power wash cleaning solution from the wood with plenty of clean fresh water using 500-800 psi with the nozzle 8-12 inches from the surface for full effectiveness of the cleaning and to prevent damage to the wood.
5. Allow the surface to dry for at least 48 hours, or to have a moisture content of 18% or less before finishing.
6. All horizontal surfaces must be sanded using 60-80 grit sandpaper. Always sand in the direction of the wood grain and remove sanding dust.
7. Proluxe Cetol Log & Siding Wood Finish should be applied within four weeks provided that the surface remains free of dirt, grease grim, mildew).

Special Notes:
• Sikkens Proluxe Cetol Log & Siding is not manufactured with lead or mercury containing materials.
• New pressure treated lumber requires a six-week drying period. Water-repellant lumber requires one year of weathering prior to application.
• New rough-sawn wood less than four weeks old should be dry-brushed with stiff bristles to remove loose dirt and fibers. If debris is still present, follow the preparation procedures.
• Weathered grey wood or wood affected with blue fungi or rust from nails may be treated after the surface preparation by applying a solution of four ounces of oxalic acid crystals in a gallon of warm water. This solution should be allowed to sit on the affected areas for 15-20 minutes before the final rinse with clean water. Let dry 48 hours before coating.
• It is always recommended to perform a full system color test on a sample of the wood.
• Previous coatings must be removed prior to the application of Cetol Log & Siding.

Previously Coated Wood - Previous stains, varnishes or sealers must be completely and thoroughly removed prior to application of Sikkens Proluxe Cetol Log & Siding. After removal of previous coatings, clean and prepare surface as specified above.

New Wood - Clean and prepare all wood surfaces as specified above. Pressure treated wood must be properly seasoned, dry with a moisture content of 18% or less and free of salts and other water soluble materials before applying stain. Water- repellent treated lumber requires one year minimum of weathering prior to cleaning and application.

Exotic Hardwoods - Ipe, mahogany, iron wood, tiger wood and teak woods exhibit a dense cell structure which may reduce the ability of a coating to penetrate the wood surface. Clean and prepare all wood surfaces as specified above. Immediately prior to applying coating, wipe surface with acetone.

Checking Moisture Content Before Staining:
• Sikkens Proluxe Cetol Log & Siding cannot be applied when the moisture content of the wood is over 18%.
• If applied on wood with over 18% moisture content, mold and mildew may grow beneath the finish which may cause peeling, cracking and failure over time.
• It is recommended to use a Moisture Meter to test the moisture content of your wood before starting your staining project. A good moisture meter can be purchased at most hardware or home improvement stores.

Caulking Cracks, Checks, and Gaps:
• Fill all joints, cracks and nail holes with a quality acrylic latex caulk/filler such as Perma Chink Energy Seal or Weatherall UV Guard Textured Caulk prior to applying Sikkens Proluxe Cetol Log & Siding.
• Any cracks or checks that are upward facing which can hold water need to be sealed immediately to prevent any future rot or decay.
• Some larger cracks may need Closed Cell Backer Rod to help insulate and fill the space in ensure a proper seal.
• An annual inspection of all corners, butt joints, windows and doors is helpful in insulating and maintaining the life of your log home.

Sikkens Proluxe Cetol Log and Siding Application Information
• Test wood for absorbency by sprinkling water on the surface – if water is absorbed within 30 seconds – 2 minutes, depending on climate, the surface is ready for finishing. If water is not absorbed, wait 30 days and re-test.
• Before starting, test your color choice on a small area, applying all coats required. Proluxe Cetol Log & Siding Wood Finish color Natural Light will weather faster than others. This color is not recommended for use on darker colored woods.
• Stir thoroughly with drill mixer such as a Shurline 5 Gallon Paint Mixer before and periodically during application. intermix all product together before starting to avoid color variance.
• Brushing is the preferred method of application, using a natural bristle brush (such as a Wooster 4” Bravo Stainer), if applied by roller or airless sprayer, back brush immediately to ensure penetration and to avoid an uneven finish. For airless spray, use a .011”-.013” tip at 1200 - 1700 psi, adjust pressure as needed.
• Apply when the surface and air temperature is between 50° F (10° C) - 90° F (32° C).
• Do not apply in direct sunlight, if rain, snow, heavy dew or low temperatures below 40° F (4° C) are expected within 48 hours.
• Do not thin.
• After preparation, apply 2 coats of Proluxe Cetol Log & Siding, waiting a minimum of 24 hours between coats.
• The first coat must be thoroughly dry before application of the second coat. If possible, back prime with the first coat. During application, saturate all end grains, nail holes, cavities, and cracks in the wood.
• Brush on a liberal coat and maintain a wet edge to prevent lap marks. Brush in the direction of the wood grain starting at one end of the board or log and continuing to the other end of the board or log.
• The first coat of any Proluxe Cetol system should be applied from the bottom up to avoid drips which may streak the surface below. Follow with recommended maintenance procedures and schedule.

Sikkens Proluxe Cetol Log and Siding Maintenance Instructions
• Proper maintenance starts with visual inspection.
• To maintain the products protective characteristics apply a maintenance coat, when visibly required or sheen appears dull and before wood starts to turn grey.
• Areas that show minimal wear should only be lightly coated. Hardwoods and lighter colors may require more frequent maintenance.
• A timeframe of 2 to 3 years on the south and west exposures and 3 to 4 years on the north and east exposures can be used as a general guideline.
• As weathering, exposure conditions, altitude, and applications can vary, maintenance may be needed sooner and should be performed when visually necessary, regardless of timeframe.
• To identify the changes caused by weathering, we recommend saving a coated board from your project and storing it indoors. This can be used to periodically compare to your exterior surface to determine when cleaning, maintenance or replacement are needed.
• Before application of a maintenance coat, prepare the surface using the previously mentioned TSP solution but reducing the solution to 2 ounces of 100% powdered Tri-Sodium Phosphate or phosphate-free substitute.
• Let the surface dry 3 days after power washing. Apply 1 coat of Sikkens Proluxe Cetol Log & Siding or Cetol Maintenance RE.
• An annual inspection of all new cracks/checks, corners, butt joints, windows and doors is helpful in maintaining the life of your log home.
• Fill any new cracks with a quality acrylic latex caulk/filler such as Sashco Conceal Caulk, Perma Chink Energy Seal, or Weatherall UV Guard Textured Caulk.
• If Carpenter Bees are present and have drilled any new holes, it is best clean the area and seal the bee hole. Please check out our Carpenter Bee stain additives for preventive solutions.
• An annual cleaning of the structure with a log wash like Perma Chink Log Wash helps to prevent any accumulation of dirt, pollen, dust and airborne contaminates.
