ENVIROGUARD™ Window & Millwork Painting Instructions

ENVIROGUARD cellular PVC windows and millwork should be painted with standard oil base or latex paint using industry standard painting techniques after cleaning. For better paint adhesion and long-lasting color vibrancy, click to learn about our 20-year warranted pre-finishing option.

Enviroguard product extrusions are cellular PVC, a vinyl-based composite. As such, they may be subject to thermal expansion and contraction at direct temperatures above 145 F degrees. Extreme dark colors may accelerate this situation, as dark colors tend to absorb a greater amount of solar heat, which can cause cellular PVC to expand and contract excessively and warping/distortion can occur. Distortion of frame and sash components, paint adhesion loss, blistering and peeling could also result. Painting Enviroguard products a dark color (any color that falls within the L value of 56 to 0) can generate high localized temperatures in the product. WARNING: Painting any Enviroguard cellular PVC product with a paint color darker than L value of 56 (where black = 0 and white = 100 will forfeit the product warranty. If, despite the above warning, you should choose to paint Enviroguard products a dark color (as defined above), a paint specifically designed for these applications MUST be used. Whichever paint manufacturer is chosen must be contacted to verify the paint's reflective properties and suitability with regard to painting cellular PVC. Precision Millworks Inc is not liable for paint used on our cellular PVC components or the result of its use.

Detailed Finishing Instructions

  1. • All joints and nail holes should be caulked with quality paintable caulk.

  2. • Darker colors with a value of L-56 or below should be avoided.  “L Value” is a measure of lightness and ranges from
    0 (Black) to 100 (White).

  3. • Two full coats of quality oil or water-based paint should be used.

  4. • Do not paint weather-strip.

  5. • 1/16” to 1/8” paint overlap must be left from sash to glass to avoid water infiltration.

Beginning April 22, 2010, contractors performing renovation, repair and painting projects that disturb lead-based paint in homes, child care facilities, and schools built before 1978 must be certified and must follow specific work practices to prevent lead contamination. EPA requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in pre-1978 homes, child care facilities and schools be certified by EPA and that they use certified renovators who are trained by EPA-approved training providers to follow lead-safe work practices.
