I need to replace a small front door porch stoop, which is currently black opaque-stained wood. My contractor suggested that I look into the newer, better composite or all-resin tongue & groove porch flooring. Azek seems to be well-regarded, but comes only in light colors (I'm afraid my light gray house is a different tone, and the colors wouldn't look right).

Aeratis Traditions or Classic, their web site says, is paintable. Has anyone built a porch with Aeratis? Is the paint retention on the Aeratis as good as they say? Is it slippery? I found regular alkyd porch paint was very slippery on my wood porches, which is why I switched to opaque stain.

Alternatively, I haven't found synthetic tongue & groove boards available in black or dark gray, but I would love to hear if anyone knows of such products.
