In this regard, what is the best paint to use on azek?

AZEK Trim does not require paint for protection, but accepts and holds paint very well. If you choose to paint use a 100% acrylic latex paint with colors having a Light Reflective Value (LRV) of 55 or higher.

Likewise, how do you paint composite trim? To properly prep & paint composite trim, I suggest the following:

1. Fill nail holes.
2. Caulk in trim.
3. Use the appropriate bonding primer.
4. Apply 2 coats of a latex/waterborne, high quality appropriate grade (exterior/interior) paint product.

Also to know, do you need to paint PVC trim?

Although painting PVC trim boards isn't necessary, we recommend it. PVC boards won't weather or lose its ability to hold paint. Before you paint, use mild detergent to clean off grime and oils left over from handling and make sure the surfaces are dry. Then finish it with any exterior 100 percent acrylic paint.

Do you need to Prime PVC before painting?

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.
