The Surprising Truth About Fixing Rained On Concrete Nobody Tells You

Do you ever have issues with spider cracking when pouring directly over plastic? The water tends to rise due to it not being able to absorb in the base below.

[@patmcbride9853]

I finally bought some water reducer for all the small jobs I'm doing around my house. Videos like this are a great education for DIYers.

[@steved8563]

Nice job as always Mike. Being a contractor as well, I rely on weather every single day and obsess about it when planning days out and so many times the forecasters blow the forecast so I learned to just rely on doppler radar when it comes to watching rain systems come in as well as snow for that matter because we can never rely 100% on what is forecast that's for sure. Thankfully it didn't pour torrential buckets on you so that you had to deal with huge puddles and inches of water being built up in there on you as that would have been much more challenging to deal with.... In the summertime in New England we know that thunderstorms can spawn at any time even if they're not forecast as is another reason why I always just use doppler radar above any weather that was forecast because then I can see real time what is actually incoming and how bad it is based on that.... Nice job once again Mike as always!

Thanks Steve

It rained on day 2 of my concrete pour for the apron around my garage. Happened just after it was troweled, when they were in the process of brooming it. They troweled it again and broomed it again and the results looked good but all that extra water in it caused the surface to be super weak. Months later if you turned a tire on it, or even swept it with a stiff broom, the surface would dust. I eventually pressure washed it with a surface cleaner which took away all the broom finish... but at least its not dusting anymore. I'm thinking a sheet of plastic would have been all it took to save it.

Great to hear about the mix used, the pump cost etc, helps in laying how the best way to do jobs elsewhere.

[@MikeDayConcrete]

Awesome, glad to be able to help!

[@big_mike_nyc]

Mike I have that same Soff Cut saw, my father bought it back in the late 90's and it cost a small fortune back then! It is still in use today!

[@evanhughes3027]

I loved your video mike. As a Carpenter who pours a slab for a building a few times a year, i really appreciate the educational information. Luckily, my friens is an ace concrete finisher so "Ross the Boss", (real nickname) helps me out so I get decent results. He's a good teacher, but i still learn from your videos. Thanks and stay safe, brother.

[@BudGilbert-m1o]

Great video Mike. Lots of information {HOW TO}. I did this for many years commercially. You have put together a great crew to help with the pour {placement of concrete}.You make the cutting of the slab issue look easy.

Good pour Mike ….. my flat Work guy comes pretty well prepared as well and if I have to do poured walls for a addition that I do I have one company that I deal with and he is very well known throughout this area. Crookston poured walls. They do a great job I’ve known Denny most of my life along with his four brothers who all own some kind of construction business.. Stay Safe Mike and Crew 🇺🇸👊🏼👊🏼✌🏼🔨🪚

[@ChipsPlace1952]

Mike, In a past video you mentioned the thought of expanding into possible doing walls. Any more thoughts on that?

[@heardian78]

In California, we call it "Hard Trowel" when we finish in by hand on sliders, and with a machine, we call it "Burning it Black".

Same. I had 2 discs removed and replaced with spacers, vertebrae cut out where the nerve runs through and fused with rods and screws in march. I mainly work on cars but used to get called for labor intensive work because people knew i was dumb enough to show up and work. 2 back surgeries later...

[@volleydave2012]

We use 3foot Squeegees when we pull the water off, it goes a little nicer

[@hoog111]

Hi Mike I’m from UK. Have you ever tried leaf blower to dry up your concrete? Just a thought

I haven’t seen an electric soft cut saw, that’s cool. Where could a guy get one for a good price?

[@michaelbissen1946]

[@truthsyrup5764]

The issue with a the reducer is the tearing, like gelatin, that you get. I tcan take a while of trowelling to get rid fo the tears.

What's your thoughts on rebar in garage floors where there will be heavy equipment, say perhaps a cat 420f backhoe? Do you have a video where poured a floor for heavy equipment use?

[@MikeDayConcrete]

This video shows what we do for a garage with heavy equipment. Of if the engineer just specs rebar. kzbin.info/www/bejne/q2eQkpyHpLFrl7s

Hey Mike, what crane and winch do you use in the video? Got a couple of links for it? Thanks1

[@donaldcurtis9229]

Float blades fit over top of those combo blades

[@georgeburns8447]

This Old House has made numerous mistakes over the years. There's one old episode where a basement slab like this one had been poured. They didn't protect it, a rain storm came while it was still wet, and they wound up with a severely pockmarked slab. The solution? Pour another slab on top of it, thereby losing at least four inches of floor to ceiling height in the basement, which is normally already low to begin with.

[@thormatteson7141]

It is SO important to saw-cut ASAP if you want to avoid cracks. Micro-cracks are beginning to form by the time you are done with the troweling. If you wait until even the next day to saw-cut, the cracks will have grown enough so the saw-cutting will not control where they show up.

[@basspig]

My concern is why didn't they pressure wash the wall that was up against the Earth where the concrete will bond to the wall?

[@LeighWoolley]

The concretors in us would not last 1 day here in Australia

[@billybobthorton]

[@offgridmatt]

Mike, you should attach a GoPro to your power trowel!

[@floydwilliams3321]

It happens to the best of us

[@basspig]

And their second concern is where is the rebar? There should be at least some kind of Steel meshing in that concrete to keep it from cracking.

[@MrRobertjparsons]

The edges of the saw cuts break off over time, whereas the trowel molded-in joints last forever.

Weather people aren't always right, bound to happen sooner of later.

[@amplituhedron5582]

Get windy. Use the layers for wind direction, clouds at several altitudes and radar. If you are always on the same area you will learn more accurately if it's going to rain than the weather man

[@MarkOstrowski-p9o]

How many rebar do you need to do a sidewalk

[@snicklefritzd3612]

Most sidewalk is 4" thick and doesn't get rebar unless it is in a driveway and then it's about 6" thick and still, usually doesn't get rebar.

[@MarkOstrowski-p9o]

@snicklefritzd3612 in Illinois where I live they put rebar in the sidewalk

[@ian5780]

If you want to use rebar use #4 and put it 3 inches off the form boards all around and then every 2 ft to 16 inches. Up to you unless it's not.

[@ArcanusLibero]

The more you polish it the better comes out

[@davidthomson4716]

Putting your steel trowel ON the machine is highly dangerous, I have seen some really bad gashes over the years from static trowels. Best to bend up a butchers hook and let it swing from the handle.

Thank you for pointing out that not many 'even knows' the difference. And all this time, I thought 'every1' was just talking colloquially, not that they'd mistake gravel for a 'big pet peeve' that you would complain about.

[@GRUBB-MUDD]

@richc3437 it's a huge difference, order a tone mix when u need a gravel mix. Or get a whole trialxe load of gravel when u need crushed stone. U obviously don't know the difference still so I don't even know why I even replied back

I don’t take any notice of weather forecasts re. rain, I look at the actual cloud maps (met office in UK) and make my own judgement from that. Recently had sand/cement/lime rendered the front of new build house, renderer said too much risk of rain, no I said, got a lovely finish on that overcast day.

I don't understand why you would pour concrete up against mold. 30 mins of pressure washing would have made your work look professional.

[@steved8563]

That would be the contractor's responsibility and not Mike's. I'm a general contractor and I always clean the residual soil debris on the existing foundation sidewalls before the slabs are poured. Mike was hired as a subcontractor to do the finished concrete floor and that was what they were there for and even the foundation contractors aren't going to care about anything more than where they're pinning their foundation to the existing foundation. But one would think that the general contractor of the job would want that wall cleaned up prior because that will now be on the interior of the new structure? But again, that would be why Mike didn't bother with that, because that's not his responsibility and that should have been done before they came in to do their work......

[@billabong9215]

Pressure washing does nothing for mold. You can't drown
