Anybody got any tricks/tips for re-finishing the edge of Azek after it’s been machined? I made some window boxes which have some pieces that had to be ripped and some exposed ends. Even after sanding, the machined edges of Azek seem to be dirt magnets. If anyone has a tip for re-imparting that factory finish, it would be greatly appreciated.

The most common way to make your own parging mix is to use either Type S mortar for block or Type N for brick and add a concrete bonding additive.

Try filling the cut edges with PVC adhesive, like Genova white vinyl adhesive P/N AW945.
Thanks!
I'll try that too - sounds faster than my method.
I have had decent luck by fine sanding (220) with a block, then brushing on a somewhat heavy coat of BM Fresh Start primer. Let the primer dry and then very sanding (320) again - the primer just acts as a filler for those little air holes. BMFS is sandable - which is one reason why it is my favorite.
JimNever underestimate the value of a sharp pencil or good light.
My brother-in-law was just saying yesterday that the company that comes up with a cellular PVC product where the cut edges look and perform the same as the factory edge will own the market.
I hear you on the cut edges looking different, and attracting dust and dirt too. My solution is . . . paint! I use Sherwin Williams duration gloss white with no primer and paint the whole thing.
I know, I know. If you're gonna use Azek, why should you have to paint? At least the Azek doesn't undergo the expansion and contraction with change in humidity like wood does so the paint should last a long time.
OR rebuild them with the new and improved AZEK F4S!!!!! TA-DA or maybe next time....Remember to use an approved color vinyl safe paint for anything with a high color index, dark that is
MEK....Methyl Ethyl Ketone is a solvent for cellular PVC.....
Machine and sand the edge just a "R/C hair" proud of finish......
Wipe the edge with a rag dampened in the solvent.....The solvent collapses the cells so it loses just a fuzz.........

The newer stock of Azek is finished on all sides. Think ahead and in many instances you can have a "factory" edge facing out.
