I like watching these guys at half speed. It's like watching a couple drunks trying to explain stuff to each other. Very entertaining if you have the time.
very informative video, thanks a lot! I watched many videos on TH-cam about pouring concrete and none were as simple and at the same time comprehensive as this one.
Well when someone isn't doing it properly, or with the right tools, people should know. I guess I should just do it wrong and like a jack ass then? I don't think so.
@@nicholascasatelli6949 sorry but hawk is right. We all have our opinions and ways just cause it's not the same style doesn't make it wrong. And if these videos makes anyone not agree or something just don't watch them. Simple
The hard part to me would be the screening. When to do it. When to follow up with more screening. When to trowel. Thanks for leaving that out. I have not found a video yet to shoot it to me straight. Following a recipe is not an issue. I did a small pad with premix from home depot and the finish was too rough. It looked horrible.
Concrete block aka cinderblock below grade you need to do a three step water proofing if you don't want leaks . You need to prime it then put your first coat of water proofing then you apply a mesh cloth then another coat of water proofing and then a dimple plastic . If you buy cinder blocks from a brick and block supply place they will have block ciment in bags just add water
Not sure how old this video is, but these days, wear a mask when using cement. It’s not great for your lungs. Great video. I’ve worked in a trade for 20 years but still get so much out of TOH vids.
This demo is technically accurate, but I pity the DIYer that tries to do a sidewalk without more information. Working with concrete is not as easy as it looks.
Correct. You frame a wall incorrectly ehh no big deal. You bite off more than you can chew with concrete and you’ll have a bad day. Just a thought from a 25 year cement mason.
Hi guys since you're using a gauged mix, to keep its tactile strength it should be; one pint of water for each pound of cement and good luck with that one, the mix would be so stiff it would break your arms when you try to travel it LOL, no offence intended, but what is referred to as 20 - two plenty in the UK would probably be your best bet mix for a home made concrete mix which would consist of 4 shovels or concreting gravel ( gravel and Sand premixed) you could use a trowel a spade or any other implement or a gloved hand come to that as long as it's not a gauged measuring implement, and one part of cement and enough water to bring it to a creamy consistency. Ps I have worked in the wet trade for over 40 years, but as for mixing it by the book, and as I was taught as an apprentice, many moons ago you are spot on,
They only touch on the basics and got few points wrong or they were misleading, The incorrectly places the metal to reinforcement in the middle since it will never be tension there it almost useless in that location. And control joints almost never do what they're supposed too. So use an expansion joint and find postings on all the missed steps. IE Concrete float - Wikipedia en.wikipedia.org/wiki/Concrete_float
I done concrete before on many occasions and used a shovel to blend it all the together but when i discovered the hoe i found this to be the very best to mix it up with little effort and easier to work with. i never looked back. The hoe is much more fun when doing these sort of small jobs.
May I ask a question?????? When using QUIKCRETE LIQUID CONCRETE COLOR on pavers (15x15) in August, it was dry to the touch so I added waterbased sealer, LOOKED FANTASTIC. 6 months later IT WON'T DRY. How can I fix this? It was dry so I added the sealer and the sealer failed and pealed. The color is not dry underneath.
I find smoothing the surface of quickrete is very difficult compare to using your own mix, because quickrete use small jagged gravel, which gets caught on the trowel, it's just the wrong size and shaped gravel. bigger rounder river gravel would be much easier to work with.
Cement can’t really adhere to smooth stones, jagged coarse aggregate is what you want. The coarse aggregate in the bag mixes is too small though, agreed. Adding a shovel or so of Portland cement per bag will help you get a better finish
Brings back great memories of working with Phillips Construction. Did more of my fair share of side walk work. Lol . However you did forget to mention , to make sure that no tree roots are near or no ammount of skilled work one does to prevent cracking . Tree is going to crack up concrete every time
Great vid but if you do this yourself you should absolutely wear a particulate mask when mixing. The dust is terrible for your lungs, especially if youre working with poor ventilation like they are in the shop
Paul Iştoan wood expansion joints are not near as common as saw cuts or tooled joints to control cracking in the Slab. but there are always 2 guarantees with concrete, it will get hard and it will crack
Hello guys, I have a question about the 3/4 gravel that you us before the concrete what is for and what hapen if you for example just pour the concrete over a plastic in the ground? Thanks.
If you used mortar with blocks that will be in contact with the ground, in which he said not to use lime. Is there a way to reinforce it so in the future it will hold up instead of breaking down? I used lime when he instructed not to.
The demonstration with the shovels at 2:55 shows why it’s not ideal to measure with buckets either. You can get more Portland in a bucket than you can sand. That’s why you’re supposed to measure by weight, not volume, the same as you would when baking. But the reality is it really doesn’t matter on a scale this small. So you can just use the shovel, make it easier. If you really really care, use a scale. But it won’t matter. Just felt like saying 😂
FirstName LastName Agreed. Plus, when I'm interested in DIY instructions, I'm looking for complete and understandable not cost efficient. I work with computers for a living and I'm sure my approach to doing my trade when I'm on the clock differs significantly from how these building tradespeople approach "messing around" with their PC at home.
What do you do with old concrete that is severely cracked or old concrete blocks that have been left over from prior projects? In other words, how do you recycle concrete? I would love to have it crushed up to use as gravel but where I live there likely isn't a nearby crusher.
Just bash it unmercifully with a small sledge hammer and use it for fill. Use of a jack hammer for larger pieces. You can even use a diamond blade to score large pieces before breaking it up.
Can anyone give me advice on what to do if I am pouring a step on a completed slab? Would I still need some kind of material in the bottom (like they use the aggregate), or just start with concrete?
Measure down your form and make a mark, typically your joints are the same distance apart as the with of the sidewalk so on a 4’ sidewalk your joints are every 4’, lay a 2x4 across your marks and run your jointer down the edge of the 2x4. When your done float out any 2x4 lines left in the concrete.
that concrete was way too wet to broom, the steel float brings the cream up to the edge and as it sets makes it easier for the broom. (the perfect broom for concrete in my opinion is 50%nylon and 50%horsehair.) i understand for videosake they would show you the process, but there is timing for the concrete to setup and for things to be at the right readiness before moving onto the next step.
This is true, concrete will crack by nature but do a pour and don’t put any control joints in it and see how much worse it will be. All you can do is try to “control” them
7:34 You can't help a walkway from cracking?? I'd say in that case you either made it too thin or you didn't use enough steel reinforcement, after all!
In every concrete video on youtube made in America, you will never see a vibrating needle. In Europe pouring concrete and NOT using a vibrating needle is simply not done. A vibrating needle will help the concrete move in every nook and cranny and forces air bubbles to the surface making the concrete much tougher.
what type of cement do i need for footings.i'm doing a foundation for a storage shed about a foot and a half off the ground.the shed measures 10' x 9' and i'd like to have 9 footings for floor support.
Just use ordinary Portland Cement (OPC) a a smaller crushed aggregate and sand, just like the video. For a shed you'd be fine with 3000psi concrete. Just make sure you don't over water it. If you're doing something large you'll want your concrete from a concrete batch plant. Anything over a cubic yard imo.
thanks for your advice,it's surely appreciated.i bought six bags of quikrete concrete mix,but i wasn't sure if that's what i'd need for this kind of project.i suppose i should've gotten a bit more info before buying what i did.live and learn i guess,but i'll find a use for what i already have,thanks again.
Usually 1 day, on a sidewalk 8 Hours should be plenty. Normally in the interest of saving time as soon as we broom we begin skillfully removing the forms by tapping them to separate them from the concrete. You can still pull your edge off in places but it can be fixed as the concrete is still a bit workable. So with that being said you can pull forms anytime after the concrete holds its shape, but the harder it is the less likely you are to pull your edge work off.
Finally! Someone who explains it for us beginners so we can understand it,!!!
I like watching these guys at half speed. It's like watching a couple drunks trying to explain stuff to each other. Very entertaining if you have the time.
Zaappp !!! I'm kinda hoping for his sake that this is a cringe show hahalololo
Nice, got a good chuckle out of that, " there's like million baaaaaggggs!
lmao you made my day! Lost my shit when he said: "Chhaaalllaannnggge mmee heerrreee Rooogeeeeerr?"
That was very entertaining to watch at half speed. 02:55 for the "Chhaaalllaannnggge mmee heerrreee Rooogeeeeerr?" part (credit Fatih)
Lmfao I'm dying. I did this once I read that
Helps to mention for the beginner that "Grade" means simply the ground or the ground level, including its slope.
Ken Johnston I’m trying to work here and I was like, “grade”? How do I google that🤷🏾♂️thanx
I wish this guy was my teacher for everything. Concise, important and easy to digest information, no bs.
This is yalls best video yet. Very detailed for beginners.
Best concrete demo I've ever seen!
very informative video, thanks a lot! I watched many videos on TH-cam about pouring concrete and none were as simple and at the same time comprehensive as this one.
Excellent video on the difference and uses of concrete, cement and mortar which I was confused with!!
I love reading the comments from all these self proclaimed experts. The guy is a professional. Sorry he doesn't do your way
Well when someone isn't doing it properly, or with the right tools, people should know. I guess I should just do it wrong and like a jack ass then? I don't think so.

Be a sheep. You gotta be a Democrat. Baaa
Here for a how-to, but arm chair QBing. Lol
Tip: coat wood form with used motor oil for easy separation. 👍
I prefer mixing the sand and Portland thoroughly before adding the aggregate. It's a lot easier to get an even mix.
I watched another video by these guys and they did exactly that. I think his helper just added the aggregate in too soon lol
Thanks for explaining the different kinds of cement .
It's 3am and I have no clue how I got here
Peppa Pug So what
Same and I have to get up at 5:40 AM today
Peppa Pug best comment ever
Peppa Pug you have paws, how the hell you use a computer!?😂😂😂😂😂
LMAO!!! Been there.....
They showed a concrete example of how to mix concrete.
The hard part to me would be the screening. When to do it. When to follow up with more screening. When to trowel. Thanks for leaving that out. I have not found a video yet to shoot it to me straight. Following a recipe is not an issue.
I did a small pad with premix from home depot and the finish was too rough. It looked horrible.
as someone used to being around cement, all this flying cement dust in the video made me want to sneeze and eyes feel dry
Jonathan Luckhun Don't forget the cement in your lungs
Silica dust😷
I instinctively squinted my eyes when I saw the dust lol
Funny I squinted and held my breath 😂😂
This is a $2000 OSHA violation payable by each offender and an additional $10,000 from their employers.

Wow, thank you gentlemen, for putting in the work for this very informative video.
Best video I found on explaining how the terminology, the mixing, and the setting. liked and subscribed. Thank you
Not sure how old this video is, but these days, wear a mask when using cement. It’s not great for your lungs. Great video. I’ve worked in a trade for 20 years but still get so much out of TOH vids.
It's interesting to hear, after all these years, it still referred to as PORTLAND cement, as if there were really any other in this context.
3 parts sand
2 parts aggregate
1 part Portland cement
Mix sand and cement together first before adding aggregate.
super useful video, more like this please!
This demo is technically accurate, but I pity the DIYer that tries to do a sidewalk without more information. Working with concrete is not as easy as it looks.
i
Correct. You frame a wall incorrectly ehh no big deal. You bite off more than you can chew with concrete and you’ll have a bad day.
Just a thought from a 25 year cement mason.
I see this as probably good for someone repairing a single damaged sidewalk section...
Since TOH is an information show it's worth noting that the word is "masonry", not 'mason•ar•ry'
James Crowley lol i thought did he say masonary?
Thats a north eastern american accent. Bawwwston.
I like what they had to share it was very good Thanks
Hey that looks like a lot a Hod woik ya know ya gotta look out for those Shop Edges❗
Hi guys since you're using a gauged mix, to keep its tactile strength it should be; one pint of water for each pound of cement and good luck with that one, the mix would be so stiff it would break your arms when you try to travel it LOL, no offence intended, but what is referred to as 20 - two plenty in the UK would probably be your best bet mix for a home made concrete mix which would consist of 4 shovels or concreting gravel ( gravel and Sand premixed) you could use a trowel a spade or any other implement or a gloved hand come to that as long as it's not a gauged measuring implement, and one part of cement and enough water to bring it to a creamy consistency.

Love the watch Roger is wearing.... Classic all time best digital basic model.... CASIO F91 W i guess...
Cool to learn to make a self mix!
Exactly what I was looking for. Great video! Thanks guys!
Was really hoping you'd cover drying and curing, too.
They only touch on the basics and got few points wrong or they were misleading, The incorrectly places the metal to reinforcement in the middle since it will never be tension there it almost useless in that location.

Very simplistically explained, thanks. Assume it's for school children and will explain it very well to them. Thanks for posting.
Mix the mixture down on the ground with the spades and then place it on the mold.
Thanks for the video, helps me save a buck to spend on the basics,
Amazing Amazing Amazing VIDEO! !! THANK YOU Best one on youtube so far!!! Learned so much
Wow! Great job and DIY motivation for both men and women!
Extremely informative. Thank you.

If your existing concrete patio has a rebar stain which developed over the years, can you resurface it to cover the stain?
That was a GREAT video.
Take a shot every time he says "Portland Cement"
Edward James Bickels 🤮🤮🤮🤮🤮🤮🤪
Drag the brush across..it'll give the waaaak way some texture
I find smoothing the surface of quickrete is very difficult compare to using your own mix,
because quickrete use small jagged gravel, which gets caught on the trowel,
it's just the wrong size and shaped gravel. bigger rounder river gravel would be much easier to work with.
Easier to work with but it will also mean the finished product won't have near the same strength and will begin to crack much sooner.
Cement can’t really adhere to smooth stones, jagged coarse aggregate is what you want. The coarse aggregate in the bag mixes is too small though, agreed. Adding a shovel or so of Portland cement per bag will help you get a better finish
I wanted to wear a mask while watching this video.
covid prediction, wtf ?
thanks for the information sir...thanks from malaysia
KL was fun
I learned a lot. Thank you.
I love the Boston accent!
I like it., because im a rooky. Thanks for teaching me.
I mix mine in the Irish tumble dryer.
Doing it manually in a wheelbarrow is too much like hard work!

However you did forget to mention , to make sure that no tree roots are near or no ammount of skilled work one does to prevent cracking . Tree is going to crack up concrete every time
Thanks - great episode!
Sand is technically an aggregate not just stones
I’m pretty sure block mortar has lime as well.
Yeah that was completely wrong.
great video
Great vid but if you do this yourself you should absolutely wear a particulate mask when mixing. The dust is terrible for your lungs, especially if youre working with poor ventilation like they are in the shop
What # of stone is recommended for the sidewalk cement?
7:20 I saw construction workers placing some wood separators after pouring the concrete, for large parts in order to not crack.
That is just to control the crack. Don't let anybody fool you but in any large slab even with rebar, concrete will always crack.
Paul Iştoan wood expansion joints are not near as common as saw cuts or tooled joints to control cracking in the Slab. but there are always 2 guarantees with concrete, it will get hard and it will crack
I have rotten wood in my expansion joints. If I pull that out, what can I replace it with?
Get some aerosol spray foam and fill the gaps. It will reduce tripping hazard and stop dirt and weed seeds from getting in there.
Will it stand up to the sun and rain?
Thank you for the video. I want to build a 8'x8' small shed, what kind of gravels (below concrete) should I use for concrete mix?
Very helpful
You should invest a segment on Roman concrete?
That's a lot of dust to breathe in if you're indoors!
Hello guys, I have a question about the 3/4 gravel that you us before the concrete what is for and what hapen if you for example just pour the concrete over a plastic in the ground? Thanks.
If you used mortar with blocks that will be in contact with the ground, in which he said not to use lime. Is there a way to reinforce it so in the future it will hold up instead of breaking down? I used lime when he instructed not to.
It looks good from my house
You guys used the right brand Quikrete America's #1 brand! Made by Americans for Americans! Chris in Albuquerque
good stuff!
i prefer stir fry, the wok way.. i'm certain they have it wrong
Some great info
The demonstration with the shovels at 2:55 shows why it’s not ideal to measure with buckets either. You can get more Portland in a bucket than you can sand.

When purchasing the sand, rock and Portland cements to mix yourself, how do you calculate how much you need?
The gives a number of square footage. X by 5 is my guess 2 sand 2 Rock of equal portions
This video is way better @.5x speed
I want to see how it's transported
lol at all the tradies commenting on the small slab taking a long time.. don't think they understand concept of demonstration
FirstName LastName
Agreed. Plus, when I'm interested in DIY instructions, I'm looking for complete and understandable not cost efficient. I work with computers for a living and I'm sure my approach to doing my trade when I'm on the clock differs significantly from how these building tradespeople approach "messing around" with their PC at home.
Ironically it takes Tradies a long time to ever call you back or get around to actually doing the job
Except they finished it wrong. You're supposed to broom at the end and edge and float first.
This was not a good demonstration
Right. I’m surprised they got that wrong. Edge and groove THEN broom. It matters.
Why use a shovel to mix when you could be making things easier with a spade?
I do like Poatlind Cemyint.
What is this substance called 'sand' that they are using?
Do i have to add stone?
What do you do with old concrete that is severely cracked or old concrete blocks that have been left over from prior projects? In other words, how do you recycle concrete? I would love to have it crushed up to use as gravel but where I live there likely isn't a nearby crusher.
Just bash it unmercifully with a small sledge hammer and use it for fill. Use of a jack hammer for larger pieces. You can even use a diamond blade to score large pieces before breaking it up.
Pelease add a short vídeo to show the pour hardened and stripped from the form.
Can anyone give me advice on what to do if I am pouring a step on a completed slab? Would I still need some kind of material in the bottom (like they use the aggregate), or just start with concrete?
So is that the same sand used to make garden soil drain better? What is it called?
You need to use washed river sand when making concrete.
How to you make sure your control joint is straight?
You could use a level along side as a guide.
Measure down your form and make a mark, typically your joints are the same distance apart as the with of the sidewalk so on a 4’ sidewalk your joints are every 4’, lay a 2x4 across your marks and run your jointer down the edge of the 2x4. When your done float out any 2x4 lines left in the concrete.
I am asumming youu heve a use for the slab of concret?
what's a grade line?
Ever tried making your brick mix using GFRC ?
GFRC should be used more. Since like in this post the metal reinforcement is improperly placed...
this is enough to make any DIY'r call for some help
that concrete was way too wet to broom, the steel float brings the cream up to the edge and as it sets makes it easier for the broom. (the perfect broom for concrete in my opinion is 50%nylon and 50%horsehair.) i understand for videosake they would show you the process, but there is timing for the concrete to setup and for things to be at the right readiness before moving onto the next step.
Could you do parts by weight?
Control grooves never seem to work. Even in professional pours, I've seen concrete crack where it wishes.
That's because professional means somebody that does something for a living, not somebody who is good at what they do for a living.
This is true, concrete will crack by nature but do a pour and don’t put any control joints in it and see how much worse it will be. All you can do is try to “control” them
Maybe your not putting them in correctly, like for example at the right depth......
control joints, ever drive on a concrete highway.
Nctelli 113 control joints don’t do much controlling but without them you’d see a difference.
7:34 You can't help a walkway from cracking?? I'd say in that case you either made it too thin or you didn't use enough steel reinforcement, after all!
In every concrete video on youtube made in America, you will never see a vibrating needle.
In Europe pouring concrete and NOT using a vibrating needle is simply not done.
A vibrating needle will help the concrete move in every nook and cranny and forces air bubbles to the surface making the concrete much tougher.
A needle poker also segregates the Aggraget sand and cement weakening the concrete..
vibrating sidewalk is an overkill.
what type of cement do i need for footings.i'm doing a foundation for a storage shed about a foot and a half off the ground.the shed measures 10' x 9' and i'd like to have 9 footings for floor support.
Just use ordinary Portland Cement (OPC) a a smaller crushed aggregate and sand, just like the video. For a shed you'd be fine with 3000psi concrete. Just make sure you don't over water it.
If you're doing something large you'll want your concrete from a concrete batch plant. Anything over a cubic yard imo.
thanks for your advice,it's surely appreciated.i bought six bags of quikrete concrete mix,but i wasn't sure if that's what i'd need for this kind of project.i suppose i should've gotten a bit more info before buying what i did.live and learn i guess,but i'll find a use for what i already have,thanks again.
is it 3 part sand 2 part stone and 1 part cement in weight or volume?
volume, as shown in the video
I love ❤️ putting concrete in my underpants!
Same 😂😂😂
yeah, that way im always rock hard
how long before the mold can be removed and the cement maintains its form?
It depends on the volume of concrete and how wet the mix is to begin with, but leaving it overnight should be fine in most common situations.
I meant concrete
If you're in a hurry you can paint the inside of the form with old car oil and remove the same day if careful.
1 day
Usually 1 day, on a sidewalk 8 Hours should be plenty. Normally in the interest of saving time as soon as we broom we begin skillfully removing the forms by tapping them to separate them from the concrete. You can still pull your edge off in places but it can be fixed as the concrete is still a bit workable.
