Help with self leveling 100m2 floor

[peter241]

Hi every-one, sory i havent been on for a while, ive been up to my eyes in work. (its about time) LOL.

Any way i have a job comin up 900m2, 3 of the rooms require self leveling. (100m2) i havent attempted this amount of leveling before and was looking for some advice.

I normaly use a 20 kg bag of multiflow screed for leveling.

Can anyone advise me on the best way to tackle this project?

Do i use the 20kg bags or can i get the leveling compuond in a mixed form? or should i contract the job out?

Any advice would be apreciated

Leveling surfaces that large is a ***** without specilized mixing equipment.

Sure, you can do it with regular buckets, but I'd use atleast a tub mixer for the job. You could rent one, or a pump/mixer. Or you could sub the leveling out.

I'm attaching a pdf where you can see what type of of tub mixer I mean. It's the one on the second page.

An average leveling compound would require in the region of 130kg of powder for every mm on 100m2.


Use a spike roller and a wide floor scraper to smooth the compound if you decide to do it yourself.

It's the only one I could find demonstrating an effective method. When you're using leveling compound, you want to work fast.

It doesn't demonstrate how you build a gradient though.

Read this and this as well, for some extra info.

For that amount of levelling a would recommend a pump mixer or sub it out......

Dont know your working situation, are you a one man band or is there a group of you?
Not something i think could be handled alone....well i wouldnt want to.

Me neither!

Yupp, same here. If you're not used to leveling large surfaces, and you don't want to risk anything, it might be a good idea to sub it out. If you want to have a go anyways, do get proper equipment.

Some time in the future, I'm going to invest in a pump mixer myself. Leveling floors can be a lucerative niche if you know what you're doing. I'll probably wait until I start employing people though. Leveling large surfaces isn't really a one man task.

Thanks every one for the feed back.

I do have a few people working with me so the labor isnt a problem, I have experience in leveling floors but nothing on this size.

I will take your advice and hire a pump mixer, i fancy having a go. and like sWe said, it can be a lucrative business. The thing with this job is they have already had the floors done but thes ones need leveling are pretty bad.

I dont want to lose the contract ove the cost of the additional labor for the leveling so i will tackle it.

He isnt to happy about having to pay for it twice anyway .

Wish me luck

is the floor bumpy or do you need to pick up the level to meet a datum ? sometimes when the floor is bumpy its easier to grind the bumps out wit a concrete plane makita doone with a hoover attachment to keep the dust down

There is an Alfa Romeo garage being converted around the corner form me.............big building firm in to sort out and lay 220m floor.

They self leveled last week with latex, and a couple of days later it was all cracked.............( gloss painted floor????) anyway, they had to lift it all again and yesterday self levelled again...........today, it was still wet, just 10 minute ago went past there and could see a infa red heater going......all night???

They also mis measured on the tiles and they are 20m short................the tiles come from Italy and are as specific to Alfa showrooms.

Someones head is gonna roll.

It was due to be finished 3 weeks ago

So for all you newbies, and I spose oldies.............watch and check wot it is your self levelling onto

like i stated in a previous thread i use self leveling compound almost on a daily basis covering the old asphalt floors containing asbestos, the floors are on average 45 to 50 sqm i can cover this area in aprox 2 hours that including setting up and applying sbr. I use a large bosch mixing drill with a with a large gorrila tub and the compound is cempolatex, the house would take around 6 to 7 20kg bags of latex. I do this on my own with no labourer so 100sqm would be a walk in the park and 1 hell of a bonus [money] about £5 a sqm dont be afraid of it, its not hard work but continuous. hope this helps
Hey £500 notes is not bad for a mornings work:lol:

you can self level on to almost any thing as long as the correct bonding agent is being used [i learnt the hard way blown floor] tech advisor came down to the offices to do a short course on the stuff. No more blown floors:hurray:
