Azek on concrete. - Contractor Talk - Professional Construction and Remodeling Forum

I am contemplating putting an azek trim board around my front forch slab. Has anybody ever done anything like this, and does the Trimbonder work well for that? It claims it does in this article. http://www.azek.com/article.php?id=66

Application - to be put above veneer on the slab edge

With all the expansion and contraction of the Azek, I would still use mechanical fasteners, maybe some tapcons countbored and plugged. The glue will hold, but I think the movement between the concrete and Azek over time will weaken the bond.

Thats just something for water to get behind, I dont see why you couldn't use it but, I probably wouldn't.

from where I'm sitting, I don't think the transition you have now looks bad.

Just adding railings IMO would pull the porch together well enough...

We are not adding railings to the porch. It was just an idea the wife had to finish off the front of the slab. I liked the idea because it would give me room to box out the bottom of the columns with Azek to make them look like this mailbox post at the bottom, otherwise they are too close to the edge. (a little taller than this mailbox post)

The more you sucure AZEK Trimboards the less ability it has to move...fastening ever 12" on center and using an adhesive such as Lexel has been successful

I think i see what you are trying to accomplish, it looks from the photograph that some of the veneer sits proud of the cement deck, when standing on the deck you will see random pieces of stone that stick out. As the condition exists water will get down into that opening and eventually the freeze and thaw could start poping pieces. If you add azek you will still have a seam that is visible from the top and will collect water and debris. If it where my house i would break up a nice piece of copper, cut a kerf into the cement, and cap the whole detail off. This will take care of water penetration, will conciel the edge variation of the stone, and IF DONE CORRECTLY, will look real nice. G

Im kind of surprised code or your home owners insurance doesnt want a railing on the porch, that has to be pushing 40+ inches on the high end isnt it?

Gene - this is a very good idea. Will look awesome next to the natural stone.

If Done Correctly being the operative phrase here. Maybe even worth bringing in a metal guy if it is something the o/p is not comfortable with.

Once the beds are filled in, the step off is 2 feet. We do not want railings, though I see your point with the insurance thing. 30" is the maximum it could be before the AHJ says something, that is why we built the beds.

As much as I hate to say this, we are not looking to spend a lot of money, and if Azek wasn't an option, we were just going to rub it and be done. That sounds like the way to go, not really keen on fastening every 12 inches. That's 70 feet of Azek, thats a lot of drilling and filling.
