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 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 80 - 120 grit sandpaper. Always sand in the direction of the wood grain and remove sanding dust.

Special Notes:

• 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 three days 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 the Cetol 1 RE and Cetol 23 RE System.
• Cetol 1 RE is always used as the first coat in any bare wood application.
• All systems consist of three (3) coats.

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.

Weathered Uncoated Wood – Clean and prepare surface as specified above.

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 1 RE 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 am 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 1 RE Stain.
• 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 1 RE Application Information

• Allow to dry a minimum of 24 hours.
• Must be top coated with two coats of Cetol® 23 Plus RE Top Coat,
• 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.

Sikkens Proluxe Cetol 1 RE 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 of Cetol 23 Plus 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.
• 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 house wash helps to prevent any accumulation of dirt, pollen, dust and airborne contaminates.

Sikkens Proluxe Cetol 1 RE Application Do’s and Don’ts

Application Do’s…
• Prepare your wood properly for stain and finish application. Mill glaze, the shiny surface created when lumber is planed, may keep coatings from penetrating.
• Intermix different batches/cans together to ensure color consistency.
• Apply when the surface and air temperature is between 50ºF and 95ºF (10ºC and 35ºC).
• Saturate all end grains, nail holes and cracks in the wood.
• Maintain a wet edge to prevent lap marks.
• Apply in the direction of the wood grain using a long haired natural bristle brush.
• Stir well before using with a paint mixer . Do not shake if using product the same day.
• Back prime (if possible).

Application Don’ts…
• Do not apply over previously coated surfaces. All previous coatings must be completely removed, except structures already coated with Sikkens Proluxe Cetol Log & Siding or Sikkens Proluxe Cetol 1 & 23 systems.
• Do not apply when the surface is hot to the touch.
• Do not apply when dew or frost is present or expected within five (5) hours.
• Do not apply in wet weather.
• Do not apply when moisture content of the wood is greater than 18%.
• Do not thin with any mineral spirits or paint thinner.

Product Questions

  • I have some outdoor benches that I was considering using Sikkens Cetol 1 on. Can I use this stain on the benches? Do I have to use a topcoat?

    Sikkens Cetol 1 is ideal for outdoor furniture! You can use (3) coats of Cetol 1, waiting 24 hours between coats. This will give you a satin, durable finish to your furniture. You can also use Sikkens Cetol 23 Plus as a topcoat to add a little shine and a more water-repellent finish.

  • I have some left over Cetol 1 and Cetol 23 plus. I wanted to use for a couple of tables in our backyard. This is the older Cetol product before they added the RE. Is this still appropriate or safe for me to use on our outdoor tables? Thanks!

    PPG would recommend using three coats of Cetol 1 here. The Cetol 23 would be too soft and would tack as the surface temperature increases. Two coats of Cetol DEK would work as well if you like. Also, the change to the RE formula was just a change in the solvent to lower the VOC's in the stain. This was to comply with changes in external government regulations, and was not done for any health and safety reasons.

  • How many coats of the Cetol 1 & 23 are required?

    After preparing the wood for application, apply one (1) coat of Cetol 1, and two (2) coats of Cetol 23 plus. Proluxe requires a minimum of 24 hrs dry time between coats.

• Apply when the surface and air temperature is between 50ºF and 95ºF (10ºC and 35ºC).
• Saturate all end grains, nail holes and cracks in the wood.
• Maintain a wet edge to prevent lap marks.
• Apply in the direction of the wood grain using a long haired natural bristle brush.
• Stir well before using with a paint mixer . Do not shake if using product the same day.
• Back prime (if possible).

• Do not apply when dew or frost is present or expected within five (5) hours.

Product Questions

  • I have some outdoor benches that I was considering using Sikkens Cetol 1 on. Can I use this stain on the benches? Do I have to use a topcoat?

    Sikkens Cetol 1 is ideal for outdoor furniture! You can use (3) coats of Cetol 1, waiting 24 hours between coats. This will give you a satin, durable finish to your furniture. You can also use Sikkens Cetol 23 Plus as a topcoat to add a little shine and a more water-repellent finish.

  • I have some left over Cetol 1 and Cetol 23 plus. I wanted to use for a couple of tables in our backyard. This is the older Cetol product before they added the RE. Is this still appropriate or safe for me to use on our outdoor tables? Thanks!

    PPG would recommend using three coats of Cetol 1 here. The Cetol 23 would be too soft and would tack as the surface temperature increases. Two coats of Cetol DEK would work as well if you like. Also, the change to the RE formula was just a change in the solvent to lower the VOC's in the stain. This was to comply with changes in external government regulations, and was not done for any health and safety reasons.

  • How many coats of the Cetol 1 & 23 are required?

    After preparing the wood for application, apply one (1) coat of Cetol 1, and two (2) coats of Cetol 23 plus. Proluxe requires a minimum of 24 hrs dry time between coats.
