Going to have to put a bunch of Azek crown and bed mold profiles. How should I do the inside corners, miter or cope? If cope does a coping saw do a good job I usually do crown with a grinder. 13′ run in that area, with an inside and an outside
I think there is only two inside corners on the house, there are a bunch of outside ones though, Azek glue the way to go with that?
How bad is the expansion,? its painted tan. What should I do if I have to splice a long run, butt joint? I think there might be a 20′ gable thats getting 4″ crown, the most common basic crown profile around. Tell me everything Ive got to do it right away.

Regarding expansion, if you paint it with a dark color (or "colour" for our UK friends), you're going to have trouble. Tan is one of those "could be light, could be dark" colors. There's specs somewhere on acceptable reflective values. A friend of mine painte his brown and it's a mess. Mine is white and no problems whatsoever.

Its true its a darker tan, the light reflective values thing-- how would one find out what a custom paint colors value is, azek says 55 or less is cool, dont have a clue how to find that value out
S-W used to have special formulations for that. Can't remember exactly been a coupla years. Had to do dark brown once. they had a secondary formulation that produced the same color with better reflectivity....

I can't help but wonder if they were pulling your leg. My understanding is that the color itself defines the LRV. Did you happen to ask them what they meant by "better"?
I don't completely remember.
But they got to the same color by using a different/higher combination of lighter tints as opposed to the standard mix...
Had a bunch of Duration mixed for other non-sensitive areas - normal formula. Got around to the porch and raised my concerns to them about reflectivity. Totally different formula , yet the same color. And no problems to this day. Dark dark brown.
They could have been pulling my leg. Don't really care. Client was , and is, happy, so am I.
I aint a chemist. Ask them...
Everytime I do , they have the right product for me. Yes, I'm a fan of S-W. Because they give me results - in some sometimes rather peculiar applications - they perform.

Benjamin Moore's fan decks list the light reflectivity value (LRV) for each color so that's one way to find out.
I assume Azek wants 55 or greater since the higher the number, the greater the reflectivity, with pure white being a theoretical 100. In my experience with paint (not with Azek), an LRV of 55 is a pretty dark color. I think I would be inclined to paint exterior vinyl quite a bit lighter.
The "lightness" of any color is referred to as it's Hunter L value. A value of 0 is black, 100 is white.
I was once told by an Andersen rep that painting their vinyl cladding with any color with a Hunter L value lower than 60 would void their warrantee (in otherwords, anything over 60 should have no negative impact with respect to thermal expansion of the vinyl cladding).
I don't know how to determine the Hunter L value of any given paint color, but I'm guessing that a paint store would be a good place to start.
i'd like to thank you guys for ruining my day.
i just used probably 300' of aztec on a house,put up the last pc today.
all painted dark brown.
if this is a problem why doesn't it state it on the product.
i'll wait and see.the older i get ,

I haven't used a dark color on PVC trim (such as Azek), so I don't have any first-hand experience how it will hold up. There's probably a lot of variables and maybe you'll be ok. Let us know. I've certainly made my share of mistakes... and there's always more to come.
For what it's worth, Azek does state in this technical bulletin to use an LRV of 55 or higher. It also states:
For paint colors equivalent to an LRV of 54 or lower, paints specifically designed for such applications must be used, such as Sherwin-Williams VinylSafe™ coatings.
What paint did you use?
I saw that about dark colors on Azek as well. But, if it helps you sleep any better, here's a pic of the Azek facia on my own house that's been up and painted a fairly dark shade of green for going on three years now & still looking like new. I think the longest run is just over 16', and I've never had any movement problems.

Edit: I did use the SW paint approved for Azek.

most of what i have used is window sills,maybe 6',window trim 5'. but i do have 2 runs 1,is 16' other is 20' in 2x8 material. i may luck out on those because it's on the south side of the house,so dead summer sun doesn't really hit and then the 2 story house next door semi shades that trim.
i would puke if the sills give trouble,i thought when i was putting them in,i sure would hate to be the guy that has to remove these. i used pl glue, screws,and caulk like i was never going to replace again!!
i wonder if i was to recoat with the sw paint if that would be effective over the standard duration paint?the older i get ,

I don't know, but I would suspect not because it's the expansion/contraction due to temp changes (solar gain) that would cause problems with the underlying paint. But I think that Duration is supposed to be one of S-W's "vinyl-safe" paints. Check it out on their website.
Painting it a lighter color would certainly help.
Unless I'm mistaken, I think Duration is one of the approved paints. I wouldn't worry about 6' sills. I don't think any movement you might get over that relatively short lenght will be an issue.
I'm curious about the 2X product you refer to. AFAIK, Azek only comes in thicknesses up to 5/4. Who makes 2X? I'd love to be able to use that for sills on occasion.Mike HennessyPittsburgh, PAEverything fits, until you put glue on it.
your right,i mistyped that,it's atcually called 5/4= 1" x8
i'm like you i was not able to find a 1 1/2 thick to make my sills out of. so i used the 5/4 and glued a pc to it that made the 3"ridge inside the nose.the older i get ,

I don't cope inside corners with Azek. I mitre them and when installing use Flex caulk in the corner. I think Flex caulk/adhesive is a product from the same company that makes Bond & Fill.
Just a tip. It's a mess to try and wipe it. I usually let it dry for a day and then cut the squeeze-out with a knife.
