I have some 6x6 posts that I am wanting to frame up and trim out with stone, brick or something.

Just wondering the best way to frame it out? I see wood and I see cinder blocks. Do you just attach a type of backer board to your frame then set the material?

wood frame example from google:



Similar goal:

My rock guys did not use any kind of frame. Just worked their way up using mortar and rock. And it is not stacked rock like your example shows. We wanted a rock faced look with the rock standing on edge. It is completely hollow besides the post and has been fine.

Having said that, I just had a rock wall built around the perimeter of my patio. Again, it was not stacked rock but a facing rock. I did build a wood frame and faced it with OSB. The rock guys used wall ties with the rock much like the brick guys would use.

I would build the wood frame around the post and face it with OSB. Cover the OSB with 15 pound roofing felt.

Probably a dozen ways I can think to do that off the top of my head. Did a set with copper flashing that looked great, another with stained cypress and a brick cap.

that's not a bad way to do it. like Clames, i can think of a bunch of ways to do this. HOWEVER: use treated lumber even if the posts are under roof. i'd also use hardi-backer to wrap the framing

I'd have to use some kind of frame.

With a 2 year old, I'm sure he would hit it with something and knock it down

So basically, treated frame (2x4 more than likely), hardi-backer screwed to frame, mortar in stone veneer?

yes. i'd suggest using a mastic to adhere the stone to the hardi-backer instead of mixing up a batch of thinset. keep some shims handy in case the stones want to sag or droop while the adhesive material sets (+/- 24 hours).
tape off any finished surfaces next to the work area because the mastic or mix-it-yourself thinset stains and can be hard to remove when its dry.

Why not just use cinder blocks? I'd much rather use them and mortar than make a frame with a backer material. Shouldn't cost much more, maybe $10-20 per at most but that would be worth it to have something solid imo.

I think I have decided to go with cinder blocks.

A few questions:

They will not be flush up against the posts, so do I need to use some type of tie in a few of the joints to solidify everything?

Will using mortar between each layer of blocks suffice rather than filling the entire hole(s) with concrete?

Once blocks are set, do I just skim coat and add stone veneer?

You can tie them back to the posts, yes.
And you don't fill the holes with concrete just top of bottom course block and butter the block you are setting. Make sure when you start your bottom course that it is level and clean.

Oh and you might be able to get away with the narrower block vs the full size.

And you should be able to apply stone directly on block after skim coat.

this is what I would do as well...based on my experience, the less wood you have at the base of your posts, the less maintenance you will have in the future.

As a pool builder and outdoor living builder in Houston, my stone masons always use cinder block base then stone. Wouldn't do it any other way.
