Concrete Subfloor Leveling in a Large Area MrYoucandoityourself 

I appreciate the time all of these workers take to show us these things. It slows them down a little and their time is valuable. Thanks for this and all of the other videos like these!

This is by far the best video I’ve found on RU-vid for self leveling a subfloor. Thank you very much.

Ahhhhh.. finally. Now THIS is how its done. Good ole' fashion experience. Great job!

Out of all the videos I’ve seen this was by far the best this guy is a pro great work

You do good work! Thanks for sharing how you do these jobs.

Looks great! Good prep floor makes the job so much easier

Thank you for sharing. By far the best video showing a novice how to level an existing floor. Uncomplicated and to the point. Great tutorial. Should one put a bonding agent on the existing concrete?

Thank you doing this video. Educated me even more about this process and tools for the job!

Jose Mourinho has started his own construction company. You sound just like him. Thanks for this video.

A thousand thanks for being such a big help!!! I will buy through you.

Thanks for making this video, it gave me some great ideas. The lazer level must save allot of work.

They are doing it right. Great contractor.

Oooh those tripods are a great idea!! I've only just done by first ever job on my kitchen floor, a couple of bags and this was my main worry, wondering if I have my heights ok. Luckily it's turned out ok.

Impressive as always

WOW!!!! Just wow! You are amazing!

Also, that's an amazing effort on your own 👌

⭐️ love the tripod 😎 thankyou for sharing your knowledge ⭐️ 👍

I hired and fired two different contractors after paying 5k to level my floor. Neither of them could flatten my floor enough for wood flooring. After watching your videos I learned what they did wrong and I tried it myself. Floor came out perfect thank you so much for the help. Thanks to you my nightmare is over.

that is the most precise technique i have seen, these grade elevators specify the height needed... needs a patent !

Thanks for that 👍 Fantastic job too 👏👏👏

You make it look so easy

Really really good quality work. I am afraid to do so I will keep feather finishing low and sanding high.

It’s so level there’s not even a fraction of light getting under that straight edge. Good job 👍

Great work! I thank you for the information as we are in the beginning stages of a basement finish and will use this as reference to level our floors!

Wow nice work. Can you explain more about the tool you use with the blades when you are wading in the mixture as well as the tripods?

After I seal my perimeter areas. I always measure out in 24in sections the width of my gauge rake spreader. I mark with a sharpie the measurements on the ends of each 24in section. Doing such gives me a better idea of how much I should pour in that area. Just another way to try to do the best job I can. If I could post a pic of my sections I would. Great video btw!!

Soooo awesome thanks for sharing

you can always tell how well you are getting on by the reflection in the wet mix. Any warps from a light source means not flat.....this guy has a mirror on the floor 😀

Excellent Video! 🤠

For this big project I used a special instruments - tripods. They are really help to make very nice leveling. I highly recommend. You can support my channel buying this tripods. Here is link on my website page - - Floor Screed Tripods - bit.ly/2uVCPfX

Your a bad ass! I love your work.

Thank you for the video. I found this is the best video for floor leveling. I have a question. I have started leveling using a water method to determine unevenness in one of rooms and I have placed leveling cement over a clean cement floor without first using a bonding primer. This application is for a residential job with a minimal unevenness. Can I leave it as it is, or do I have to remove it now and repeat again first using a primer? The bonding cement seems to be firmly placed . I plan to use a vinyl plank flooring product over it.

Good job !!!

U a hard working man done all this alone not a easy task to complete

Thanks for all the videos! Big help. What if you have a low spot at the doorway to the room… do you end up with a ridge at the edge leading into the next room? Wouldn’t you then have to raise the level of that entire room to match? Lastly, do you mix your compound with more water than it calls for to allow more workable time?

Very informative video. Just wish I had the confidence to do the 70 square metre area 🥴🥴. Thanks very much👍

This is so cool! How big of an area can you do at once as one person? Meaning how long before it dries? If the house is too big and you want to do the whole house, you can break it up into individual rooms, as long as the level meets correctly at the doors yeah? Thanks!

Awesome video. My home is from the 70’ and the builder made a slope of about 1 feet in 25 feet of linear basement. The whole surface is about 500 ft2. Do you know how thick I can go with self leveling concrete?

Looks good

nice work

Very nice video 👍

liking finger before touching silicone... nice trick

Good job sir

One big remodel I'm doing right now, house on slab, 1500sf was self levels in one pour.... He used something called uzin ... He said it was the best stuff you can get but very expensive. What brand do you like using the most? Your experience and skills are amazing to watch bro.

great tip

This is Mapei underlayment...What do you recommend that is supposed to be used as a selflevel finished concrete floor? This is what I want me floors to be as a finished floor. A nice smooth natural concrete finish. EXCELLENT videos!!!

Thanks for the great tutorial. I guess you can use cheap concrete or stucco first is the out of level is too much, and then at the end use this more expensive self leveling?

It looks easy!

It was very nice working progress and excellent result !! I just have question for you please I am after levelling rough large area do you thing in some places if I need to go over 30mm I will be ok ? because the bags of the cement said max 30mm thickness ? Thanks in advance for your help.

Incredible result. Amazing level and uniform color. I usually get swirls of colors which are unsightly. What is that tool you are using at the end (like a roller with spikes)?

Are you mixing the ratio of water to each bag as recommended or a bit thinner? When I’ve used this stuff and mixed it according to bag instructions it comes out more like pancake batter. Yours looks a lot more fluid

Nice!🫰🏼

Ready to lay anything on that bad boy 👍🏼👏🏼👏🏼

Nice....who said this can't be done alone...lol you got the juice buddy...only a few of us left

you are very good

I've done it sometimes on my job sites, and it's always really difficult to achieve a good result. Especially if the slope is not "constant" and you have "bumps" (I hope you know what I mean)! I guess it would be almost impossible to achieve a good result without tripods. Great video, thanks for sharing your skills!

Great video. Thanks for sharing. Did you mix the mapping novoan with sand?? In the video you add water, then you put the white bag mapei and after that you add one clear bag and back to a white bag again. Im assuming that the clear bag is sand?? Thank you

What is the name of that big metal you used in the final of the video? Great video

Beautiful job ! You the man Awesome

I think I'm about to do a 750 sqft basement myself using mapei self leveling compound. Should be a good time.

I added 200 square feet to my garage when i did whole house remodel/rebuild. The cement guy started at the slant of the existing 400 sq ft garage and added on the additional 200 sq ft. The issue I having is when we get heavy rains here in Texas, water comes in under my garage door. I have been wanting to add some concrete to level out the garage to get rid of the slant and raise the newer part of the garage floor. I believe i would need to add 1.5 - 2 inches of concrete/leveler to fix the issue I am having. Any advice would help. Thanks in advance. Very nice work!

Awesome video ! how did you find the highest spot to put your laser ?.

How long did it take you to do the 500 soft. Did you work it yourself, thanks ken

Was a concrete bonding agent/primer used before the self-leveling? Was it also Mapai brand?

I noticed that your compound stayed wet for a lomg time. How much water did you add to the 3 bags? thanks for the videos.

where did you get those adjustable pins to help point out level.?? Great job!!

Can I do this to a triple wide mobile home that has old tile that is also uneven? The purpose would be to put down vinyl plank floor

Beautiful job, what was used to fill the cracks in the actual floor it looks like it was smoothed out like plaster

Hi great video. Question please. The difference in my floor is one inch max, similar as yours. What material to use? I see usually self leveling floors on youtube are up to 10mm deep. Sometimes if it is more than 10mm, they advice to add sand in the mixture. What material did you use and is it appropriate for one inch floor difference? Thanks

Mryoucandoityourself how do you calculate how many bags you need, as the floor was uneven? And are you only putting down as much to bring the floor up to the original highest point?

What are the tripod gauges you placed on the floor to help gauge how much to put in that area? I will need them

Did you have to treat concrete subfloor with anything for the leveling compound to bind to? You mad this look easy. In Florida on hot days this sets up too quickly to work it that long.

how powerful must your drill be to accomplish such a task. Mine went up in smoke

If you have a concrete pad that has slight unevenness, do you need self leveler, or will the mastic under the tile provide enough material to straighten out the tiles? My floor has slightly under 1/4" differences here and there but nothing drastic.

You appear to show that this "COULD" be a one man job. I've seen almost everywhere else that for the bigger jobs (which yours is), you need two men to do a large floor. My floor is approximately 900 sq ft. I wondered if "dry" edges could be next to the next pour, would I need to sand where the two edges meet to blend in. Otherwise BRAVO!

Which self level product did you use. Also it looked really wet did you use the recommended water or did you add more.

So my first poor has some REALLY ugly spots. Im going to have to grind a lot of it down. and also fill in some low spots. What product would be good for filling in spots? Use the same SLC? Im using Mapei Self Leveler Plus+.

Do you calculate how many bags do you need or are you just eyeing it based on your experience?

What self leveler compound did you use and can you finish this type of self-leveler?

Hello from NZ. You are amazing!! I'm watching so my son can do. Where do you get the tripods from? Thanks for video.

Great job , can I do that on painted floor ?

Do you have any experience adding aggregates to self levelling compound? I need to pour quite thick on top floor apartment and thinking about using a lightweight aggregate in the mix: love to hear any tips you have for this.

What is the flow time for the SLU product you’re using? That’s not rapid set is it ?

What is that long metal metal square called? The one you drag accross the floor. Thank you Sir.

nice job 👌. I would like to buy the Screed Leveling Tripods, but they are very expensive. My floor is the same way than yours 1/2, 3/4 and even 1 inch in some spots. Is there any solution to level the floor in those low spot without using 50 bags of self leveling because in the us 50 bags x 30 dollars= 1500 dollars just in self leveling cement please any advise. Also what is the water ratio for mixing. Thank you very much for your help

Excellent video! Which self-leveling underlayment product and bonding agent do you like the best? We're shopping around and trying to decide which products to buy.

Excellent ! Can you tell us how much you charged ? For materials and labor ? Thanks for your time have a blessed day Brother ! 👏🏽

What is that plastic like material you rolled against the walls to create a barrier?

What brand did you use for the self leveling concrete?

Great work!! I like to use the same material how much water do you use to make it that liquidy?? Thank you!

The levelling compound product I have says max 3.4litres of water per bag of levelling compound 5-50mm, but is it ok to use 4litres per bag instead for the same levelling compound(5-50mm) for 0-15mm actual floor levelling?

I have an old wood subfloor that is very crooked. I want to install carpet, is it better to use self leveling compound first and then cover with underlayment? Or underlayment first and then selfleveling?

Would this same process work for my 8x12 shed that I'm transferring into a tiny home? It has an 1.5 inch slant to the concrete slab its on.

Great job! What is the approx. cost / sq ft on a job like this? I have a similar sized basement that needs to be leveled and trying to gauge what the cost would be.

I need to level the floor in a room about that size that is around 2" (5cm) low in some areas. Is this method the best for this much slope? Thank you for your videos.

What is the roller called that you are using to go back through the wet patch?

UZIN products are the best!

谢谢

Hello! looks like 350 sqft. How many bags did you use? Thanks

Maybe grind the high spot he measures from first, clean proper, then seal, then level a nearly level floor and far less levelling compound required, maybe worth having a look at why the floor is dropping in the corner, or crap concreting on the base levels, if it's the concrete, I'd grind the high spot, if the floors dropping, I'd hold fire on the old levelling compound till these basic questions are addressed and verified prior to pouring a full pallet of levelling compound and hiding a problem needing a look at, nice view but the ground outside gives a hint at the floor Base conditions, maybe one of the survey options would be to disc cut a small square section of the concrete floor Base and see if the hard core bade hade been washed away by ground water, leaving a void causing the pad to slip, is there any other signs of movement in the buildings superstructure? Food for thought for anyone looking to do these works or pay someone to do them for you prior to commencement of works, just in case everyone's looking at levelling the floor and not on why the floors dropped up to an inch as a Base pad, it's either best case, crap concreting, then hind the high spot, then compound, if it's the pad, checked the building for signs of movement / damage, if building seems OK, cut a test inspection hole in the worst section and see if there if a void under pad, if there's a void underneath, locate the source of water, drains, land spring etc and remedy source of problems the fill voids, stabilise in right remedy, then floor compound, if the pad doesn't have to come out for most cost effective way of proper fix, if it does, no need for that much latex. Too many questions and hard to answer without the camera looking at these things or the client clarifying (if they are able or aware they need to). Food for thought, just levelling the floor isn't the first line of thought, unless your flipping the property and hiding/dumping a problem on someone else to deal with layer. It does happen, I've spent enough time working around this environment to have seen some crazy stuff, and had to fix it. Sent with respect to all, Best Regards.
