Great job on the yard!
how did pouring the concrete firepit go? I am planning to do 2 counter tops for my patio
Thanks! The concrete wasnt too bad, made the forum out of Melamine, and used caulk to fillet the corners and edges. I did the upside down pour, rather than the pour in place.
Overall it came out good, but I didnt vibrate the first few layers enough so there were quite a few air bubble holes after it was done curing. I was using my orbital palm sander without any paper on it as a vibrator, and it worked ok, but didnt get all the air worked free. I definitely recommend spending extra time vibrating. after 48 hours I pulled it out of the mold and flipped it in to place (easier done than said! it weighs ~300 lbs lol).
I used sand paper to smooth out the few high spots and smooth over the corners and edges even more. then used a fine filler concrete mix to fill the air holes. I tried all sorts of methods to work the slurry into the surface, ended up using my fingers as the best method, then used a hard scraper to remove the excess. Definitely worth the effort, its super smooth and "soft" now. definitely make the slurry very watery, easier to work with and the concrete will absorb most of the water out of it.
Finally got a generic waterproofing concrete sealer. It wasnt food grade because I wasnt expecting to do anything like that out here. just wanted to keep the water off and whatnot.
