    a friend of mine does all types of stone/tile work. He said if doing a large job with many bucket mixings, fill a bucket to the exact amount of water then drill a hole at the top level. you'll always have the correct amount of water to pour into mixing bucket.

      @barkershill ??? .... you decide where to drill the hole based on the volume or weight of substance you wish to consistently measure. If you want 5 gallons or 2 litres you will fill the bucket to the level you want and then drill a hole at the fill line so any excess drips away. ....

    Learn from my mistake! My son and I were pouring self levelling concrete over newly laid 3/4" plywood to lay down a concrete floor for a bathroom (to be tiled). I mixed and my son poured and spread. We needed 8 bags of cement. The problem was the cement started to set rather quickly, after about 15 minutes. So when my son poured freshly mixed concrete it refused to meld with the setting concrete and created lumps and dents. It took me half a day to grind off a big bump in the floor. Plus we had to do another corrective pour to fill an area that was lower (a big dent). This all could have been avoided if a) 1 mixed 2 bags at once in a larger container like a garbage can, mixing one bucket at a time was too slow, you need to have as much liquidy cement on the floor as possible 2) had we had a spiked roller to even the edges and 3) watched this video.

    Pretty good video - you covered just about everything, and clearly. A couple of points I'd add: #1 / I totally agree with the viewer who said you need a person mixing and helping with the carrying, so that the spreader can concentrate on that. You want as much as possible of the area to be runny at the same time. Once the compound starts to firm up, you will have lost the opportunity to achieve a truly level floor. YOU DON'T GET A SECOND CHANCE with this stuff. #2/ The spiked roller is almost essential if you want a really smooth and level finish. The spikes constantly break the surface tension, HUGELY aiding the leveling process. The difference between spiked rolling, and trowelling only, has to be experienced to be believed. I have tried both, and I will NEVER again do a project without the spiked roller. 3/ Spiked shoe bases again are highly recommended, if at all possible, as you can walk all over the job without leaving craters, that may or may not level up properly. #4 / Don't try to feather out any edges to a zero thickness, certainly if the leveller is intended to be your finished surface. Apart from that .. happy levelling. It's a great addition to the building game.

    Great job! Handy tip I’ve used before is getting a flat disc on a 9” grinder and just going over the floor for half an hour taking of the high bits, also with mixing I’ll normally add half a bag and give it a quick mix, then add a quarter, mix that then add what’s left, just means you’re not fighting a big lump in the middle, keep up the good work!!

    A couple of things you might want to consider for priming. On a rough floor like the one in the video you should use a stiff bristle broom instead of a roller. The reason for this is that no matter how carefully you sweep a dusty concrete floor there will always be a residue. By using a broom and scrubbing in the primer you actually incorporate the dust into the primer instead of just rolling over it. It really makes a big difference in the bond strength.. Oh and a convenience tip - instead of pouring the primer directly on the floor, put it into a bug sprayer and spray onto the floor prior to brooming it in. It's neater and prevents puddling.

    If you use a piece of wire e.g. cut up a wire coat hanger and hang it over the internal edge of the bucket at the required level you are guaranteed the correct amount of liquid every time without having to search for the measure mark. This works particularly well for mixing coloured 2 pack mixes where you cannot see the measure marks. You just make 2 measure wires. One for part A and one for part B.

    If you have a short paddle mixer and a lot to mix, build a sturdy platform for the bucket to sit on so that you are standing upright, It will save a lot backache.
    Also, mixers can take a few seconds to stop so a hanger to suspend the mixer on between uses saves valuable time.
    The cable tends to wrap around spindle easily as it doesn't stop spinning immediately so I extend the flexible grommet to help keep the cable away from the moving parts.

    Trace a line in the bucket after that..
    Pouring severals graduated glass of water into the bucket increase the error marge every time resulting in an innaccurate final reading.

    Absolutely perfick. Am retired now but did exactly as you advised except for one thing. In Australia we can buy a “walking trowel” specifically for this work. Means you pour as you did by walking pouring the bucket along the perimeter of room and then whilst standing the trowel which is on a broom handle 400mm wide fixed at about 30 degrees on long side and you gently ‘sweep it” back and forth. Great for around toilet pedestals into corners etc. the trowel has the leading edge at right angle to the short sides but rounded on the top clean edge. Was able to do large areas without bending or soiling knees.

      Because this is not self-leveling how I imagine it. If you would like to install a floating floor, this would not be leveled enough... You would have to make much more self-leveling concrete/mixture (in much more bigger container) and pour it at once... Not mentioning that by this way of self-leveling you could have problems with furniture (table, wardrobe etc.), while the floor would not be leveled perfectly.

      @@MrTomasekk A "floating floor" by definition is a floor (usually a slab topping) that isn't physically connected to the subfloor structure. An application is to reduce impact sound transmission. If the objective is to achieve a level floor surface over a substrate that deviates from level by in the order of 15mm then a "self levelling" i.e. floor that can flow to form a level surface, is what is being very well demonstrated in this video. If you need to level a floor that's more significantly out of level, a different method can be used. Over an existing concrete floor a concrete topping can be applied by scrabbling the existing surface to form a key, priming with a cement and water mix, pouring, compacting and levelling the floor. If the concrete surface is to achieve its intended strength then covering it with plastic sheet (or keeping it wet) will retain the water required for hydration of the cement in the mix for a sufficient time.

    The explanation on concrete curing "drying" was very well said. This is why you can't leave concrete in a mixer or bucket and simple add more water. It will cure under water. The mix might be different but it will still get hard. Also, this is why concrete is covered with plastic to strengthen it, if the air is very dry. Rain doesn't effect concrete aside from physically disturbing the surface.

    In my experience self levelling compound (SLC) is usually not self levelling. It's just self smoothing, at best. Just spreading it around can leave it looking flat when wet but once dry you can easily find +- 5mm variance in thickness over a 1m length - even if you're using screeding tripods as a guide. To get it actually flat and level I'd say you need to use framing and a screeding bar. First do any grinding down of high spots/areas, then pick your zero reference on the floor and mark it. Your SLC will come up from that reference height to your chosen thickness. Then use a laser level (a cheap one with a basic horizontal and vertical laser is fine for most purposes) to mark on the floor heights along the lines that your framing rails will go. You'll draw your screeding bar along these rails to move the SLC into place. Essentially you're building rails that are perfectly level along their path, then using a perfectly flat edge to make sure the rest of the floor is flat. You may need to do some additional bits of grinding or patching with something like quick-set cement just along the rail paths (using the height you marked to get everything to zero) before putting the rails down.
    For the rails what you use will depend on how thick you want your SLC. For ~6-18mm you can use MDF sheets, sealed (e.g. SBR or Acrylic primer) after they've been cut into thin strips to make the rail/framing sections. If you're going thinner, say 2mm or 3mm, e.g. for a surface finish then you can use aluminium strips.
    Screw the rail sections carefully into place (after drilling and countersinking, so the screws can sit flush with the rail without causing any deformation). Place the rails just a little less than the length of your screed bar apart.
    Now you're ready to poor the SLC. Mix it really well. When pouring aim to get it roughly where it needs to be initially, and if using a spiked roller (ideally do that), do it now. Then pass over the rails with the screeding bar. Be careful not to bend the screeding bar as you move it over the rails and hold it at a ~45deg angle to the rails (so only 1 edge is in contact) to avoid sucking the SLC along after the the bar (which would mean your level wont be where you want it). Good luck! :)

      Well said. Too many try to find shortcuts from traditional methods that have adequatedly proven themselves. Quality often comes at a cost. In this case...knowledgeable and experienced hand labor. Quality should not be sacrificed for lazyness, or cost. A properly designed floor will last a long time. Whatever you spend on it will reward the client with decades or longer satisfaction.

      Never used a screed bar for the type of job you described I've always used a stand up whale tail where you push the leveler up against your predetermined dumpy heights, very effective and you can knock down any ripple after with the HTC. I use a Hippo on wheels for a four bag mix or if we do multiple floors we pump.

    • @resouris
      @resouris 3 ปีที่แล้ว +1

      I agree with the term 'self-smoothing'. It's too thick and sets too fast to truly find a level. I know this because I've just had my kitchen floor 'levelled' with this stuff and all it's done is smooth it out without truly levelling it. There are gradients of 1cm in 1.5m still. If you need to truly level a floor you need to put levelling tripods all over it and align them with a laser level before applying your compound/screed to the level shown on the tripods.

    To be specific: the water mixes with the calcium oxide(lime) to make calcium hydroxide (slaked lime) which in turn reacts with the CO2 in the atmosphere to make calcium carbonate(limestone).
    Cement is made by reversing the process. They "calcine" limestone which means heat up at a high enough temperature to drive out the CO2 and water from the limestone. The resulting calcium oxide chunks, called Clinker, get ground down to a powder in a tumbler grinder/mill and that's the cement.
    It's not just Calcium, as it often involves some magnesia and silicates, but the calcium is usually the principal component.

    First off when you spread the primer, do not put it on so thick that it pools on the floor. You want a thin coat like painting a car. He had way to much on the floor. Second that porcupine roller is for self leveler they can be reactivated. Also, you should have been mixing it in the site where he needs it not outside the building than hauling it in, its sitting in the bucket to long. You need to mix it and put on the floor immediately. Last thing is self leveler will find any little hole and flow down it so if you are working with drains make sure they are sealed off with duct tape or some type rubber dam. Or you might see the leveler drain down. This also includes under walls if you are above grade, it could flow under a wall and down to the floor below. Chalking the walls the day prior can save you a major clean up if the building is not sealed from floor to floor. Sorry wasn't intended to bash on you. You did hit the main points on the importance of the proper primer. Accurate water measurements. And mixing. Most products have a time of 2-3 mins @ 350 rpm's for example. Under mixing is as bad as over mixing.

    Propane torch for the fibers when you are prepping. And a cheap plastic bug sprayer to apply the primer then back roll (also how I apply sealants to the finished concrete) . My 2 cents.

    Excellent overview! My 2 cents - In addition to the spiky-roller, it also helps to use a notched tiling trowel or notched-adhesive-spreader-on-a-long-broom-handle to really _spread_ the goop around to encourage it to self-level. Also, a squeegee with a long handle can help flattening the goop without straining your back :) BTW - add spacer-tape along the walls, if pouring more than 5mm thick :)

    Big job. I remember seeing a truck which mixed self leveller for a second floor. They had squeezecrete to pump.
    Well done on your job. That's not easy work and lots of cleaning. I had to level on a smooth troweled concrete floor.
    Since it was a shop on lease.
    I spoke with an industrial chemist and followed his advice. You can get fine silica sand and mix with cement and also use a screedbond which is a latex synthetic rubberised emulsion system. Say for instance a bonding agent and mixed 50% with water.
    I mixed at 2.8 cement with silica sand.
    I used a feathering edge which worked quiet well was pleasing. The area I needed to cover was not as big as what you did. However I achieved pleasing results.
    Hopefully it hasn't laminated. The problem with self leveller is it is a liquid type of application and it only self levels the area you cover before the liquid hardens.
