Stamped Concrete Pad for a Hot Tub

We have been talking about getting a hot tub for awhile now.  The first step for us is creating a place to put it.  We have a nice spot under our front porch, but it is just gravel with a stoop at the moment.  I have been looking into concrete stamps for awhile and thought it would be fun project to try.

Here we are getting the area ready, Nick tied all the rebar he was a big helper there.  I had to run to Menards, because I had gotten the incorrect bracket to attach my float to my handle.  After hauling all 80 bags of concrete down our hill, I was pretty tired already.  Jen did move some bags down the hill as well, but she was recovering from a cold and dog sitting.

Maddie was a big help throughout the day too, she would fill my bucket with water (Nick did this as well), while the mixer was running and I was moving concrete around.  Originally I though I would have to get all the concrete down quickly, otherwise it would dry.  But it was a cool day fortunately, because it took probably 3 hours to get all the concrete mixed and in the forms!  We used 73 bags on concrete which took 15 pours with the mixer.

Here we have all the concrete in the forms and leveled out.  I had a hard time with the big float, I found it easier to use the hand floats to level stuff out.  I think I need more practice with the big one.  We started with the stamps in the back pretty quick, since it had been sitting there for a couple hours.  They worked pretty well.  It was getting late as we made our way to the front and the concrete was still a little wet, so I had Maddie do the stomping for a lighter touch.

It turned out pretty well for a first attempt.  I think there was too much float water when I was stamping in places, because the release agent stuck around more then I thought it would.  The concrete is supposed to be nutmeg, with hints of grey, but there is a lot of grey in there.  Oh well.  Also there are a couple low spots, but fortunately it is under our front porch, so there shouldn't be too much rain on it.  Not sure if it will be warm enough for me to seal it this fall anymore, so I hope that doesn't cause problems.  Hopefully we can find a hot tub now!
