I doubt most rental places have that long of a base. If I was going to rent something I might rent a bull float and uses a long 2x6 to screed it. A first time DIYer would catch on quicker with a bull float and it would do the same thing the power unit would do as far as finish.



Slight change of plan, the person who really wear the pants in our household (You know who im referring to ) decided we need to make it 35x15 instead of the previous 20x15 dimension.

So below is what my other option entailed.
Build a wood form around the perimeter. Screed with 2x4. Then bull float. No need to build any other wood forms ddown the middle as reference ? Does that sound good to go?

Called them just now and they were like what does that do? LOL

They do have a concrete finisher aka power trowel for $85 a day. Does it level freshly pour concrete just like a power screed?

It sounds like what I would do. Keep in mind I’m only a home owner like yourself and have only done this a dozen times in my life. When we poured the 24 x 48 floor in the house we broke it up into two days and two pours. If my math is correct if you pour a 4 inch thick pad you will be looking at about 6.5 yards. That seems reasonable to do at once given a few good helpers.

Do you plan on putting any reinforcing in it? Wire mesh? Are you going to saw cut it after for some break lines? Is the bull float finish going to be good enough for what you need or will you be hand troweling or something else? There are special trowels to do the edges and to make a break line also. Are you going to cover it with plastic as it cures? Is the pour in a location the truck can get to and deliver the mix around to your forms?

There are a lot of steps to a project like this even the preparation of the base and setting the forms.

I know how these projects can expand when the pants wearer comes on the project.

My dad used to say “Do you know how to break up an Italian wedding? You run in and yell The concrete truck is here!”

"Concrete truck is here" ... LMAO you just made my day.

A dozen time is 12 more than me. I've only done small patches in the past so I guess you can say im a concrete virgin.

Looks like I'm going to need 6.5 to 7 cubic yard total. Only got one other helper so between us we're going to wheelbarrow the concrete about 20 yard to the back yard, spread it out, screed and bull float then hand trowel. Hope we'll get by. Just a tad worry about screed with by hand because I heard it does wonder to your back

Plan on using extra chicken wire mesh and maybe a few reinforce bars for added strength. I already have an edger that Ill be using to cut 2 control joints. Hope that'll be enough.

Not planning on using plastic to cover or for vapor barrier. Will spray water mist 2-4 times within 24hrs of pouring.

Glad I joined this board. People here are so informative and helpful

Running the screed won’t be nothing compared to moving 7 yards with the wheelbarrow. I would use the heavy wire mesh just for concrete sold at the builder centers and get a hook to pull it up to the center of the slab as you go. I don’t think you will need rebar.

Look for more friends. Even post on line seeing if you can find a couple strong backs for a half day.

Here is an idea to help save your back .... Get on Craigslist and keep looking until you can buy a small cement mixer. Roll that baby into the backyard and use it to mix your mud. Hose it off and clean it afterwards. Maybe hit it with some fresh spray paint.

http://houston.craigslist.org/search/tla?query=cement

Re-sell the mixer for what it cost you.

I had a friend that did the portable mixer idea for his city driveway. He even hauled all the materials himself in the bed of a mini pickup truck. After about a week the project was going so good he invited me over to help. One bucket of this one bucket of that and a bucket of something else then a pail of water filled to the line. Turn it on and wait or mess with the load you just made or fill the other set of buckets getting ready for the next mix. To his credit he got the job done but it took most of his spare time all summer working after work. It became a joke with all his friends because it seemed all of us were recruited to help several times.

On the other hand we built a factory in Mexico and when I went down the first time they were pouring the floor 10” thick. The building about the size of a super Walmart was all done by hand. Mixed on the floor next to where they were pouring and shoveled in. They had a few hundred people working on it. We needed one footing for a big machine and it had to be a continuous pour and we insisted in a truck mixer. One showed up in about a week from a couple hundred miles away empty. They filled it by hand and mixed and poured. So it can be done.

I'm going to hire a concrete truck, since my 2 door down neighbor wants to do his too. We're going to share a truck but with only an hr to pour hopefully we can unload in time.

There are tons of ways to pour concrete. My other neighbor did it himself with 300 bag of concrete from Home Depot. No mixer of any kind needed. He dump x number of bags on the ground and mix from there.

Hey check out this video below. The tool they screed with is called EZ creed. Thinking about making one myself or just pay for one.

I just poured 7 yards in my back yard a couple weeks ago and poured 30 yards last year for my RV pad that was 16' x 100' plus another small driveway. Each time I had two guys doing the finish work and one guy as a helper. I pumped my concrete which makes it easier to fill the forms I think. On my big pad they had a form on one side and went up to a chalk line on a wall on the other. They used a 17' 2x4 and eye balled it, that one turned out great. No real low spots and just a great job. The one I just did I formed everything and my biggest section was 10' x 20' and there is more issues and unevenness in that one then I care to admit.

Your patio can easily be done with a 2x4 and a good eyeball. The main thing I would recommend would is if you can afford it get an experienced finisher for the day, he will make a world of difference. As for getting a truck and pricing, it will probably be cheaper to get a truck than to buy bags. Around here I pay about 65 bucks a yard for a truck and about 120 or so to buy it buy the bag. You should get 3-4 minutes per yard to get it off the truck before standby charges.

$65 a yard that's basically stealing compares to $115/wkday- $125/wkend a yard here in Houston. That came out about $900 on a truck, $700 for home depot bags. An addition of $1/per min if I go over the allotted time limit of an Hr.
