1. Does Celullar PVC trim require a primer?

A primer is only needed if you want the paint manufacturer’s warranty. Excellent adhesion can be achieved by properly cleaning the board before applying a topcoat of paint to PVC trim.

2. What type of paint do you recommend for coating Celullar PVC trim?

Just about any 100% acrylic latex, or 100% acrylic latex with a urethane additive, can be used to achieve superior coating durability and flexibility. Lacquers are not recommended with PVC trim because lacquers are a more brittle coating, and will not flex with any movement in the PVC trim. Paints like Duration by Sherwin Williams, Manor Hall paints by PPG and Moorelife by Benjamin Moore adhere well to PVC trim.

Paint on PVC trim will last three to five times longer than paints on wood or wood composites due to the absence of moisture in the substrate.

3. Can PVC trim be painted dark colors?

Only light-to-medium colored paints—with a light reflective value of 55 units or greater—should be applied to PVC trim. For example, using paint with an LRV below 55 units will void our product warranty. LRV is measured based on color and its ability to absorb heat. Thus, an LRV of zero (0) is black, and an LRV of one hundred (100) is white. Don’t assume the paint is a light color. We have had cases where contractors believed that the paint they used was a light beige, only to find out it had an LRV in the 20s or 30s. Consult the paint manufacturer for the LRV of your paint before applying it to cellular PVC trim.
