• In constrast to varnishes and polyurethanes, Cetol Door & Window provides optimum UV protection, while maintaing maximum clarity, beauty, and protection for the wood.

• All wood surfaces must be thoroughly clean, dry and free of dirt, grease, grime, mildew, mill glaze and previous coatings before applying Cetol Door and Window 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.
• 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 three days before coating.
• It is always recommended to perform a three coat color test on a sample of the wood.

Sikkens Proluxe Cetol Door & Window Maintenance Instructions:
• Proper maintenance starts with visual inspection.
• A timeframe of two (2) – three (3) years on the south and west exposures and three (3) – four (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 Cetol Door & Window Wood Finish.
• An annual inspection of all 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 Perma Chink Energy Seal Chink 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 Additives for preventive solutions.
• An annual cleaning of the structure with a house wash such as Perma Chink Log Wash or TruClean EX House Wash helps to prevent any accumulation of dirt, pollen, dust and airborne contaminates.
