Glueing AZEK or any expnded PVC boards

I need some trim that is thicker than what the local lumber yard stocks. Do you think I will have success gluing 1″ wide strips to each edge of a 1×6 using PVC pipe joint cement?

I'd use white vinyl glue. Not so fast drying, and it's white. Other than that it is about the same thing.
PVC glue works well with AZEK. They sell their own brand that has a slightly longer working time, but it is a lot more expensive than PVC glue.
* do not use the purple primer.
minor hijack here - what about attaching AZEK to wood?
When previous owners had my house vinyl sided, they put aluminum trim on the front edges of the window sills - great way to trap water & cause rot.
I've trimmed the sill back on one of them, and am planning on butting a piece of AZEK to it.
Can I glue the two together, or support the new piece independantly and just caulk between?
Thanx

R:
I've glued AZEK boards edge to edge on a miter joint very successfully, but I don't know how the glue would hold on a surface to surface basis. The surface may be too smooth to glue well. You could certainly do a miter joint to make your thicker trim if it isn't a lot of LF and if you set up a table saw with infeed and outfeed support.
Incidentally, there is a difference between the AZEK glue and regular PVC glue for plumbing. The AZEK glue is UV stabilized so it doesn't yellow in the sun. If you use regular PVC glue--especially outdoors--you may need to paint.

You say "thicker", but what you propose sounds like you want it "wider? (?)
You probably won't be happy with the result of glueing with PVC cement, unless the trim is in an inconspcuous location.
If you want it thicker, for example as in creating more reveal for window/door trim, you could try furring it out with strips of plywood.
At the glue joint, which is actually a weld, the PVC gets soft and stays that way. So, the joint will always telegraph.
Learned that one the hard way.
PL Premium will glue PVC to wood pretty well.
