Painting
Trim does not require painting. However, to maintain color
consistency for many years it may be recommended. If
painting is desired, we recommend using 100% acrylic
paint with a light reflective value of 55 units or higher.
If a darker color is desired (LRV 54 or lower), use only
vinyl safe paints containing reflective pigments
designed to reduce excessive heat gain (e.g. Sherwin
Williams VinylSafe™). Caution should be used with
these darker colors as they may negatively affect the
performance of the trim. For best results, use a high
quality paint that incorporates a primer. Warranty does
not cover painted/coated finishes applied to product.
Always follow paint manufacturers instructions.
