Technical Bulletin B-2 VERSATEX Paint Specification

The Sherwin-Williams Company has completed adhesion testing and accelerated weather testing on VERSATEXTrimboard and makes the following coating recommendations;

Surface Preparation
VERSATEX Trimboards must be Clean, Dry and in Sound Condition prior to coating. If substrate is dirty it should be cleaned with ProClean ProfessionalTM Prep Wash Concentrated Cleaner to remove all surface contamination.

Coating Specifications
Field Application – Sherwin-Williams recommends priming VERSATEXTrimboard with A-100 Exterior Latex Primer followed by Two Coats of SuperPaintTM Exterior Latex, A-100 Exterior Latex, or Duration Exterior Coating. Sherwin-Williams also offers a field applied coating under their “GreenSure®” product designation. Kern Aqua® BP Enamel is a water reducible polyure¬thane – acrylic top coat that offers fast dry times and no critical; recoat times. Due to its excellent adhesion properties it is an ideal coating for cellular PVC. A primer is not recommended but if you prefer to prime the trim use Aqua Kern® bonding primer E61W525.

Factory Application – Sherwin-Williams recommends factory priming with SuperPaintTM Machine Finish Latex Primer. Product should be allowed to dry for a minimum of 2 hours and then top coated with SuperPaintTM Machine Finish Satin Topcoat. For the longest lasting performance, a second Factory coat of SuperPaintTM Machine Finish Satin Topcoat or a second field applied coat of SuperPaintTM Exterior Latex, A-100 Exterior Latex or Duration Exterior Coating should be applied.

Applications
Field Application – When the air temperature is at 50°F, substrates may be colder; prior to painting, check to be sure the air, surface, and material temperature are above 50°F and at least 5°above the dew point. Avoid using if rain or snow is expected within 2-3 hours. Apply primer and topcoats using the following methods;

Brush – Use a nylon/polyester brush.
Roller – Use a 3/8″ – 3/4″ nap synthetic cover.
Spray – Airless Pressure…2000 psi Tip…015″-.019″

Pre-Finishing

Pre-finishing of VERSATEXTrimboard by a Sherwin-Williams Authorized Factory Finisher is a superior way of finishing this substrate. Factory Pre-Finishing allows the substrate to be coated under environmentally and quality controlled conditions to provide exceptional adhesion and long lasting protection. Following the surface preparation procedure above, it is important to apply a light rinse and allow to dry prior to painting.

Apply SuperPaintTM Machine Finish Latex Primer at a minimum of 4 mils WFT. Allow minimum of 2 hours to dry. For best results, factory finish with 1 or 2 coats of SuperPaintTM Machine Finish Satin Topcoat at 4.0 to 6.0 mils WFT. Allow each coat to dry for 2 hours at 77° F, 50% RH. Force Dry with high intensity hot air or infrared head to a board surface temperature of 120°F for immediate recoat and packaging after board has cooled to ambient temperature. Use an IR gun to check the temperature of the trimboard. Oven dwell time will vary depending upon the curing method being used. Typical dwell times will be three (3) to five (5) minutes.

Product may be shipped with only a primer coat, but must be top coated within 180 days after installation. Follow above instructions for Field Applied Topcoats. All exposed surfaces must be coated. All field cut edges must be primed with one of the above primers and finished with the recommended topcoats.

Packaging
Interleaving is preferred as this will create a barrier to prevent edge blocking or what we refer to as paint pick off. Blocking is common with an acrylic latex coating if trimboards are stacked together. If product is being forced dried in an oven the product must be allowed to cool to a temperature less than 100°F prior to packaging. If the product is being air dried it may take 10 to 20 days to achieve adequate cure before the product can be packaged. Factors such as humidity, temperature, air movement and the amount of tint in the paint will all affect the length of cure.

For questions regarding the above specification you may call (800) 4-Sherwin. You can also contact your local Sherwin-Williams Representative at (800) 524-5979 for Technical Data Sheets, MSDS or EDS sheets on any of the above listed products.

SPECIFICATIONS

General: Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, any contamination, and surface passivation treatments to
ensure optimum adhesion and coating performance properties. Consult Metal Preparation Brochure CC-T1 for additional details.
Aluminum: Prime with Kem Aqua Wash Primer E61G520.
Galvanized Steel: Prime with Kem Aqua Wash Primer E61G520.
Plastic: Due to the diverse nature of plastic substrates, a coating or coating system must be tested for acceptable adhesion
to the substrate prior to use in produc¬tion. Reground and recycled plastics along with various fire retardants, flowing agents, mold release agents, and foaming/blow¬ing agents will affect coating adhesion. If needed, prime with Kem Aqua Bonding Primer E61W525 or Polane W2 Primer E61AC514. If filling is required use Kem Aqua 65P SprayFil. Please consult your Sherwin-Williams Chemical Coatings Sales Representative for system recommendations.
Steel: Remove rust, mill scale, and oxidation products. For best results, treat the surface with a proprietary surface chemical treatment of zinc or iron phos¬phate to improve corrosion protection.
If needed, prime with Polane W2 Primer E61AC514.1f filling is required use Kem Aqua 65P SprayFil.

Wood (interior only): Must be clean, dry, and finish sanded. Substrate should be free of grease, oil, dirt, fingerprints, and any contamination to ensure optimum
adhesion and coating performance properties. Prime with Kem Aqua 65P SprayFil, Sher-Wood 2400 Millwork Primer E60W501, or Polane W2 Primer E61AC514.

Testing: Due to the wide variety of substrates, surface preparation methods, application methods, and environments, the customer should test the complete system for adhesion, compatibility and performance prior to full scale application.
