Preparation Procedures for New, Weathered and Uncoated Wood:

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: Spray the surface with clean water, wetting the wood.

• Recommend cleaning the surface with a deck cleaner or stripper
• Apply this solution generously to the wood with a garden pump sprayer.
• Let the solution sit on the wood for 15 – 20 minutes.
• During this period, scrub the surface with a hard bristle brush to help remove mill glaze and/or weathering.
• Do not let the solution dry on the wood.
• Keep Sikkens Proluxe Cetol 23 Plus RE Exterior Top Coat wet as you’re are working. Do your best to work on the sides opposite of the sun.
• Power wash the cleaning solution from the wood with clean water.

To prevent damaging the wood, do not exceed 500 PSI. The nozzle must be a maximum of one (1) foot from the surface for full effectiveness. Let the surface dry for three (3) days before application (i.e. the moisture content is below 18%).

Weathered gray wood, or wood affected with blue fungi or rust from nails may be treated, after cleaning with Sasho CPR Log cleaner and Brightener. After treatment, allow surface to dry for three (3) days. Fill all joints, cracks, and nail holes with a high quality Conceal color matching caulk and let cure prior to applying the coating system. Refer to caulk/filler manufacturer for proper application.

Pervious log homes with the Sikkens Cetol system may need to be corn blasted to remove Sikkens film forming stain.

Application for Pine, Spruce, Cedar and other logs Sikkens 23 Plus Topcoat

Standard Application Procedure: It is always recommended to perform a three (3) coat color and sheen test on a sample of the wood. Color can vary with application, porosity and type of wood. Intermix batches to ensure color consistency. After preparation apply three (3) coats of Proluxe Cetol 1 and Cetol 23 plus assuring thorough dry time (minimum 24 hours) between coats.

• If possible, back prime with the first coat. During application, saturate all end grains, nail holes, cavities, and cracks in the wood with Sashco Log Builder or Conceal color matching caulk to Sikkens Log and Siding colors.
• Brush on a liberal coat and maintain a wet edge to prevent lap marks. Recommended natural bristle brush with a handle where a pole can be inserted for ease of use.
• 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 Cetol system should be applied from the bottom up to avoid drips which may streak on the surface below.
• Follow recommended maintenance procedures and schedule.
• Cetol Log & Siding is compatible over an existing Cetol 1 and Cetol 23 Plus system. The system needs UV light to cure properly.
• The side that gets the least sun – You can use Cetol Maintenance Clear

The absence of UV light will significantly slow the drying process.

Wood peckers and insects?  Add Walla Walla Bug juice to the stain.

Do not apply any Sikkens Cetol system over a fresh, borate-treated wood surface.

Allow the borates to diffuse into the wood cells by allowing a six (6) month exposure time (12 months for green logs) before application of Cetol Primary 1 23plus. To prevent borates from leaching out of the exterior surface, we recommend the application of Sikkens Log Pre-Treatment over the borate treatment. Before the application of Sikkens Log Pre-Treatment, allow the borate treatment to dry for three (3) good, sunny days. Just prior to the application of the appropriate Cetol system, the log surface must be cleaned thoroughly according to the Sikkens preparation procedures.

When borate treatments are applied, it is always advised to follow the manufacturer’s recommendations. Maintenance Procedure and Schedule: Proper maintenance starts with visual inspection. A time-frame 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. However, as weathering, exposure conditions, altitude, and applications can vary, maintenance may be needed sooner and should be performed when visually necessary, regardless of timeframe.

Sikkens Proluxe 23 Plus Log Application Procedure:

Kiln-dried or Air Dried Logs: It is always recommended to perform a two (2) coat color and sheen test on a sample of the wood. Color can vary with application, porosity and type of wood. Generally, the moisture content of these logs is below 18%. However, some logs may have a moisture content higher than 18%. Therefore, it is recommended to apply Sikkens Log Pre-Treatment and then allow a six (6) month drying period before applying Cetol 1 23plus system. Follow preparation procedure before applying first coat of Cetol 1.

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.

PPG 23 Top-Coat

The first coat of any Cetol system should be applied from the bottom up to avoid drips which may streak on the surface below. Follow recommended maintenance procedures and schedule. Green, Wet, or Treated Logs: It is always specifically recommended to perform a three (3) coat color and sheen test on a sample of the wood. Color can vary with application, porosity and type of wood. Generally, these logs have a moisture content greater than 18%. Therefore, it is recommended to apply Sikkens Log Pre-Treatment and allow a one (1) year drying period before applying Cetol 1 23 plus.

Follow preparation procedure before applying first coat of Cetol Primary 1. During application, saturate all end grains, nail holes, cavities, and cracks in the wood.

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

APPLICATION: CAUTION: Surfaces are slippery when wet. Use caution when walking on wet surfaces during application. 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.

1. Before starting, test your color choice on a small area, applying all coats required.
2.  Buy sufficient product for the whole job and intermix all product together before starting to avoid color variance.
3.  Stir thoroughly before and periodically during application.
4. Do not thin.
5.  Apply when air and surface temperature is between 50° F (10° C) – 90° F (32° C).
6.  Do not apply in direct sunlight, if rain, snow, heavy dew or low temperatures below 40° F (4° C) are expected within 48 hours.
7.  Brushing is the preferred method of application, using a natural bristle brush, 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”-.015” tip at 700 – 800 psi, adjust pressure as needed.
8.  Apply one even coat of 1 Primary Coat RE Wood Finish, avoiding heavy application.
9.  Allow to dry a minimum of 24 hours.
10.  Must be top coated with two coats of  23 Top Coat RE, following label application directions.
11.  Apply in the direction of the grain.
12.  To avoid lap marks, start at one edge and follow through to the end of each board maintaining a wet edge.
13.  Coat all end grains and then the back of all boards if possible.
14.  Since outdoor furniture and fences are considered to be in a high moisture environment two coats of 1 Primary RE Wood Finish would be your best method of application.
