• 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.

Sikkens Proluxe Cetol Door & Window Cleanup & Shelf Life
• Clean all tools immediately with mineral spirits.
• Clean spills right away with a damp cloth.
• Shelf Life: 5 years maximum – unopened.

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 helps to prevent any accumulation of dirt, pollen, dust and airborne contaminates.

Excellent product

It reminds me of the old-style finishes my father (a finish carpenter) used decades ago. It takes a while to dry but it’s worth the wait. Finish holds up well to both heat in Phoenix and cold temp and winds of Northern Arizona.

Best Stain/Finish I've Ever Used

Sikkens Proluxe Cetol Door and Window Finish is the very best door stain/finish I've ever used. It's easy to apply and the door looks absolutely beautiful. If you are on the fence about this product, please, don't hesitate to purchase it. The beauty of the finished product FAR exceeds the price.

Great Product!

I originally ordered the mahogany and decided it had too much orange undertones. I added the dark oak over and it looks closer to the color I wanted. This product was recommended on a website as an alternative to gel stain and poly on a fiberglass door. Worked really well. I’ll be curious to see if it last longer than the stain and poly on our door, which faces west and gets lots of sun in the summer.

Great Product

This product was recommended for our fiberglass exterior door as a better alternative to stain and poly. Have completed two coats so far and will do another final coat. The Mahogany looks like it has too much orange undertones for what we wanted to achieve. The product itself is easy to work with, has a very strong odor, and hoping it lasts longer than the poly coat that came off in the heat of the sun.

Dark oak satin

I originally purchased this product for use on badly worn exterior door. But decided to try it on a garden bench I had just finished and I must say that the color was exactly what I was looking for. I applied three coats as recommended. Much better product than box store carry. Would purchase again! Can't wait to see what the door will look like. again.

Product Questions

  • What is the best type of paint brush to use when applying Cetol Door & Window?

    Since Cetol Door and Window is an oil-based finish, I would make sure to use a natural bristle brush or a bristle-poly blend. Natural bristles hold oil bases very nicely while polyester brushes have a hard time with oil bases. This is the only restriction to follow with this product. I would consider other options such as width, angle, or quality entirely by your personal preference.

  • Can Sikkens Door & Window finish be used on the inside of my door or is it an exterior stain only?

    Yes, you can certainly use the Sikkens Door & Window finish on all sides of your door. It is recommended that you review the preparation and application directions for this product to achieve the overall finish you wanting.

  • Can Cetol Log & Siding be applied over Cetol Door & Window if I want to add color?

    Unfortunately, Proluxe Log & Siding is not compatible with the Cetol Door & Window. Since the Door & Window is already in place, adding Log & Siding may have a tendency to peel. I would recommend that you clean the surface well and then add another coat of Door & Window in the color of your choice.

  • Can I apply a coat of Sikkens Proluxe Cetol Door and Window Finish in colorless satin on top of two coats of Sikkens Proluxe Cetol Door and Window Finish in colorless Gloss? It is too glossy and doesn't match the adjacent wood.

    That is a commonly used method to tone down the sheen of a finish that has gotten too glossy. We discussed it earlier today with PPG and they confirmed that there weren't any known incompatibilities there. Please contact us if you have any further questions.

Sikkens Proluxe Cetol Door & Window Cleanup & Shelf Life
• Clean all tools immediately with mineral spirits.
• Clean spills right away with a damp cloth.
• Shelf Life: 5 years maximum – unopened.

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 helps to prevent any accumulation of dirt, pollen, dust and airborne contaminates.

Sikkens Proluxe Cetol Door and Window Application Do’s and Don’ts

• Fill any new cracks with a quality acrylic latex caulk/filler.
• Saturate all end grains, nail holes and cracks in the wood.
• Maintain a wet edge to prevent lap marks.
• Apply a medium coat in the direction of the wood grain using a soft long haired natural bristle brush such as Wooster 5 1/2” Bravo Stainer Brush.
• Maintain a wet edge to prevent lap marks.
• Stir well before using with a Shurline 1 Gallon Paint Mixer. Do not shake if using product the same day.
• Coat all sides of doors.

• Do not use three coats of clear alone on areas that receive high levels of UV exposure.
• Do not apply in direct sunlight.
• 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.

Excellent product

It reminds me of the old-style finishes my father (a finish carpenter) used decades ago. It takes a while to dry but it’s worth the wait. Finish holds up well to both heat in Phoenix and cold temp and winds of Northern Arizona.

Best Stain/Finish I've Ever Used

Sikkens Proluxe Cetol Door and Window Finish is the very best door stain/finish I've ever used. It's easy to apply and the door looks absolutely beautiful. If you are on the fence about this product, please, don't hesitate to purchase it. The beauty of the finished product FAR exceeds the price.

Great Product!

I originally ordered the mahogany and decided it had too much orange undertones. I added the dark oak over and it looks closer to the color I wanted. This product was recommended on a website as an alternative to gel stain and poly on a fiberglass door. Worked really well. I’ll be curious to see if it last longer than the stain and poly on our door, which faces west and gets lots of sun in the summer.

Great Product

This product was recommended for our fiberglass exterior door as a better alternative to stain and poly. Have completed two coats so far and will do another final coat. The Mahogany looks like it has too much orange undertones for what we wanted to achieve. The product itself is easy to work with, has a very strong odor, and hoping it lasts longer than the poly coat that came off in the heat of the sun.

Getting familiar with product made for suucess

Coats (3 in all) went on thicker than expected. Needed to work with smaller brush to maintain best control of application. Excellent results.

Cetol door and window

I have not opened this can yet, but I have used this product many times. It is easy to use and stands as well as can be expected to harsh weather conditions.

Great product!

I loved the finish but the can open slightly during shipping and made a mess. Not a lot leaked out maybe an ounce or two but it should be in a sealed bag or fastened better

Dark oak satin

I originally purchased this product for use on badly worn exterior door. But decided to try it on a garden bench I had just finished and I must say that the color was exactly what I was looking for. I applied three coats as recommended. Much better product than box store carry. Would purchase again! Can't wait to see what the door will look like. again.

PRODUCT QUESTIONS

Product Questions

  • What is the best type of paint brush to use when applying Cetol Door & Window?

    Since Cetol Door and Window is an oil-based finish, I would make sure to use a natural bristle brush or a bristle-poly blend. Natural bristles hold oil bases very nicely while polyester brushes have a hard time with oil bases. This is the only restriction to follow with this product. I would consider other options such as width, angle, or quality entirely by your personal preference.

  • Can Sikkens Door & Window finish be used on the inside of my door or is it an exterior stain only?

    Yes, you can certainly use the Sikkens Door & Window finish on all sides of your door. It is recommended that you review the preparation and application directions for this product to achieve the overall finish you wanting.

  • Can Cetol Log & Siding be applied over Cetol Door & Window if I want to add color?

    Unfortunately, Proluxe Log & Siding is not compatible with the Cetol Door & Window. Since the Door & Window is already in place, adding Log & Siding may have a tendency to peel. I would recommend that you clean the surface well and then add another coat of Door & Window in the color of your choice.

  • Can I apply a coat of Sikkens Proluxe Cetol Door and Window Finish in colorless satin on top of two coats of Sikkens Proluxe Cetol Door and Window Finish in colorless Gloss? It is too glossy and doesn't match the adjacent wood.

    That is a commonly used method to tone down the sheen of a finish that has gotten too glossy. We discussed it earlier today with PPG and they confirmed that there weren't any known incompatibilities there. Please contact us if you have any further questions.
