Hi. Is there a minimum maximum depth you can use this mix on. I have a floor with a 30-40mm belly in the middle ( 30 - 40mm too 0 )So the mix wouldn't be the same depth throughout. Thxs m

[@macplastering]

it dose like 3 inch depth on top of insulation as a minimum I think if your on a solid you can go as low as 30mm I have on very few jobs went lower but with loads of precautions taken such as going over a nice clean floor that i have hit with sbr so that it will bond well also having sbr and fibers in the mix to make it stronger and less likely to crack... there are also wet mixes like self levelers might be work a look as some now can go up higher than before

If you can gently cut back further and add a little more try over lap it you can also sbr under it try or something that can seal the subfloor

I have to screed over an old painted concrete floor (I'll prime it first) and thickness would go from 3 to 45mm - would this mix work?

The 3 mm would be very hard to get that to stay on we would put this gear down 3 inches at the norm how did you get on ? sorry for late reply been very ill

[@ColinMill1]

I have a slightly less difficult job with a wet room screed that, at its thinnest will be about 15mm thick. I have made a sample with 6 grams of fibres per litre of cement and 300 ml of SBR per litre of cement and 3 litres of sand per litre of cement. I cured it for 24 hours at 45C so I could test it quicker and it is already pretty tough. However, from all I have read the only solution for something 3 mm or less is an epoxy screed that costs a small fortune.

Can I lay patio slabs on this mix?

[@macplastering]

I have seen the guys laying them with a wet mix mate and was talking to a guy who lays them says he uses sbr now in mix also to stop them popping especially for natural stone type, I think you could use this but the bond wouldn't be great unless it wet to help stick/bond

[@ariashley]

Could i use screed on a stable floor as i only have 7cm available and the base is concrete?

[@macplastering]

3inches on a solid sub floor is normal mate i think you are just below that but if sub floor is sound it shouldn't be to bad you can add fibers to mix and sbr are you putting down ppm or is that already in the floor below?

Great video - thanks for sharing! I have a bumpy garage floor that I want to level off for garage flooring tiles. There is a 5-6” gradient back to front where it meets the driveway, so levelling compound is a no go. Could you tell me, what’s the thinnest this kind of screed can be applied please? Cheers!

[@macplastering]

The thinnest I have ever when was 10mm in places with no issues but I dont lots of preparation I bonded to floor with sbr added sbr to mix and also fibre's to help reinforce the screed , both floors where tiles one I would still see now and again and it has lasted very well , but if you plan on driving on it you might want something stronger than screed like a liquid concrete ?

[@watty13]

mac plastering Thanks for the reply. Yeah, thought as much. It’s not going to have to support a car (garage not long enough), but it’s probably still pushing it as it will probably be shallower than 10mm in most places. Guess I’ll try and coax a floor screed to not run out of the front of the garage 😉

@@watty13 10mm is realy pushing things and if it dont bond or cracks you will be back to the start , what's down now is it concrete ?

@@watty13 floating screed should be laid around 65 to 75 mm thick a foating screed is on insulation and dpm = damp proof membrane, but this would be called a bonded floor witch would still be recommend to go 25 to 40 mm if this was my house and I really didn't have room to go higher but wanted to get it much more level I wouldl either get a suitable self leveller or if need to screed my plan of attack would be get that dust off brush t hover it until is as dust free as possible then I would do a say 5 to 1 mix 5 water 1 sbr and paint the whole floor a day before to seal that dust down then the next day when im ready for the mix I would have sbr in the mix bear in mind it will speed up setting time but add strength , there is other additives that can add strength sutch as fibres so I would get them in again they can and will making finishing that little harder but will act as a reinforcement to help reduce cracking so I have my mix read before I dump it out on the area I am about to start I will again paint that area with pure sbr and go over it while its wet so the mix will set with it giving the best bond possible bond , another step I might think of is scoring the floor some but it might cause more dust and mess that it could help , Screeding is no easy task for sure and this type of floor is very challenging but hope I have gave some good points for you do think over , you might be safe doing a small test area somewhere to test strength and bond before going at the whole job ? again hope this is helpfull mate

75mm is best its around 3 inch's I add the fibers to the mix adding to the water will just make them stick in lumps and not spread out I also use sbr as a goof bonding it is also water proof hope this is helpful mate

[@macplastering]

The optimum thickness of a sand and cement bonded screed is 25-40mm so 20 is pushing it to the limit The lowest I have ever went on a job was 10mm but I compacted it real well was a strong mix in the fact i added fibers and sbr to mixes to help reduce the chances if it cracking and also sbr / bonded the floor i was going over with neat sbr that floor is now got tiles on it and has been ok for a good few years now , its one of them jobs it is risky but I done everything I could to make the best job possible , the floor i was going over was between 2 rooms one was 10mm in places lower so i needed to level them through for the tiles I was working over and existing screeded floor so i had a solid background what will you be working on top off my friend ?

Hi mate sorry I thought i answered this but seen that i haven't Have not done one in a while so trying to look back n my book to see how far we went down , I thin one room was down to how far down the founds where as we could not undermine them so this might be a good way for you to start mate. So if you dig down untill you see the founds then measure up and see what you have to pay with , Read one time that the soil types can and will effect foundation depths ,clay soil , sandy soil , piled founds So when you have it all out and clear they way i would go about it is measure down so you need from 65 to 75 mm for your screed then what ever amount thickness of insulation you want in say another 65mm I think that is minimum required next then would be the subfloor concrete witch minimum would be 4inches thick so what ever is left you now need to fill with hardcore best to whack down like 3 inch layers at a time to make sure it is well compacted and no voids I whack it down in a few diffrent directions also side to side up and down then around and at angle to angle over kill possibly but this is the 1st layer start as you main to go on, so i would use lose stone to fill some followed buy blinding its stone and quarry dust mix gets very very hard when compacted as the dust fills all voids very well when wacked locking it together. I mark my sides where i need to come up to so i dont fill to high and end up with less concrete insulation or screed that i need remember you can always add some concrete up but not down same as screed so if you lower with stones than amid you can make it up on the next level with concrete , if your getting it ordered give them sizes they will work out how much needed get a skip and add 5 to 10% on depending how big the job is to make sure you dont run low and can dump rest if you did run out of screed never run it down into a slop but cut it of and either mix more or buy more to finish like this little demo - kzbin.info/www/bejne/jqa3lXp7itSEsJo These are the ways I would go about it Hope this all helps and still here if need any more ideas mate

[@jamskof]

@@macplastering no, ive only ever been told to use some kind of bonding agent. theres going to be waterproofing done on top of the screed as its a bathroom. in oz they use strips that are about 100mm wie that cover all joins, and then a waterproof paint on all wet areas

[@macplastering]

@@jamskof The dpm s to stop damp coming up mate here we have to use dpm and insulation most times the dmp is under the concrete then another layer with the insulation to be safe then screed but if you cant then for sure a bonding agent will do no harm at all keeping the floor down

Hey, quick question. Would you consider using this kind of screed for a shed base or would you use wet concrete?

[@macplastering]

Depends I think concrete would be stronger but is it a light shed for light stuff ? thing is even when we screed it always has a sub floor of concrete most imte the sub flor then insulation then plastic and screed on.... Oh mate if you ever come arcos a video we have done and think of a better title just let me know :)

[@squidlings]

@@macplastering cheers. Will do bud. How do u edit your videos? Also what camera do u use?

[@macplastering]

I have used so many cameras and software mate windows movie maker open shot camtisa you name it I proply used it and camreas cheap 30£ ones to dear sony and a go pro now the most with a jvc and sony back up something tells me 4k is needed but again would it matter would it make a difference ?

[@squidlings]

@@macplastering I used to be a photographer. Camera makes a huge diff. You need something with a decent iso. The better the iso the less light you need to get good quality in low light and cos your alway working in dark houses it might make a difference. Brighten up the shot. Little techniques like position the camera so the light from the window is shining where u want to film. New iPhones have brilliant cameras (I'm an android guy but my daughter has an iPhone and the cameras are way better) So yeah if u spend on a genuine go pro (not cheap knock off) you'll get far better quality. Also having a flood light would help if it's dark. I know u probs don't wanna go that far just yet. Then u can edit the videos a bit more "youtuby" to make them more instantly likable. Dunno if you've ever watched "Chris fix" he is a car repair guy who developed a brilliant catchy style of videos. People watch them even if they have no intention of fixing their own car because his style is so watchable. Makes it look so easy and shows you all the dos and don't in a fun way. Might be worth watching and seeing if it's something you could apply to your videos. Might take some planning out. Imagine you hit it off on KZbin tho. Cha ching. Do you make a few quid from your videos as it stands?

[@macplastering]

Only seen this reply now mate sometimes I dont get notified from youtube. Thanks for the advice mate yes seen that guy the blue gloves :) to be honest i just dont know my style yet but i might get it when it lands on me like a pile of blocks get some but not very much as of yet and to get this stage has took real hard work in the videoing editing and at same time doing the job... if you ever get spare time mate pick your fav video of mine and tell me why I will try replicate those things :) also let me know what your thought are on the new stuff as it comes :)

[@macplastering]

Great question the sand I use is called sharp sand it is very coarse , but i have used a coarse plastering , hope you subscribe for more :)

[@juanluissalazar9734]

I ask you because here in Mexico we use sand and gravel (crushed hillstone) we mix sand, gravel, and portland cement, empty the firm, and then we have to give it the finish with cement diluted in water and hit it with the trowel, and I see in the video that when going battering is already polishing

[@lazarsjojic]

Hi man, great video. You really look like a guy who knows what's he's doing. Great explanations. I am trying to do leveling of screed in apartment. It's the old building made in 60s. And screed is done in good quality, but it's very uneven. I have a difference in 3cm in one room. I wanted to level it with Mapei Topcem. This is basically just like regular cement but just on "steroids". You can do whole screed with it, or you can lay it over existing screed to level it up. I made a small patch of screed just to tested it and now am not sure how good that is. So I would like to check with you few things please. If you can answer these help that would be great help for me. 1. The granularity of sand I'm using is of size 0-4 mm. What granularity do you use for your screed? 2. Maybe you can do a video where you are actually showing how hard screed should be, by making a small patches of screed and scraping it, hammering it and destroying it so we can see what to expect on how good screed looks like. There are almost no videos on youtube about it this and I think this is important. I guess you can make a nice youtube video on this. I have no idea how to tell if my screed is hard enough (or even too much hard because I hear some people are saying that screed should not be hard as stone) 3. Since the screed is harder the more you compress it, why don't you walk over it to compress it better. What I stamp it hard with my feet it gets really hard. Is this good thing to do? 4. I can not accomplish that top part of screed (2mm layer) is hard as the part under it. The top 2mm of my screed are not ideally even and they get a bit brittle when you scrape them with a tools. I also don't know how to really fill all these little holes on the top. Can you make a close up view on how you are making the finishing surface of the screed so we can see how actually you surface looks like? Thanks man. Once again your help would really mean a lot to me.

[@macplastering]

I will try to do these test you say I have been wanting to do a few diffrent test on plasterers and other things , not sure if you have seen our how to screed a floor = kzbin.info/www/bejne/eZqVq4icq853itE We dont do loads of screeding but next time i am doing a job i will for sure record it and get some close ups of it, yes the more you compact it the harder it will get. Also after you lay a floor if you give it a few mist coats of water to slow the curing down it should get harder. our sand would be at its biggest 4mm. The job you are doing is very hard to do but what i would recommend would be take of any lumpy high areas any thing that is like 6mm fill with that cement as you where doing then for the lower areas i would get a high quality 2 part liquid screed and fill those up ad then if wanted you could give the whole floor a 2mm coat to make it look better Before all these steps though i would seal the areas with an sbr coat to help bond it all down so it wont lift up after it dries Hope this was a helpful reply buddy and be sure to have the bell button on to be notified of new content and hopefully your suggestion video :)

[@lazarsjojic]

@@macplastering Great man, thank you very much :). You reply is very helpful. I was actually thinking the same thing as you said with liquid screed. By "liquid screed" do you also imply self leveling compounds? I was thinking to use them. I watched you how to screed video several times. I subscribed with the bell! Looking forward to your next videos :)

[@macplastering]

@@lazarsjojic yes sorry the liquid screeds i would use have self leveller in them I have found the 2 part stuff the best not only is it better to work with but better ad easier to mix as its pour in the liquid then the powder cant go wrong :) Thanks for subbing buddy means a tone the support :)

[@chrismetcalfe4827]

Hi Mac, great video as always. I'm considering screeding the entire floor in my bungalow, as we have taken down all the internal walls and the floor levels differ between rooms. The floor area is 44m². I have not attempted something like this before but I am keen to try things and learn skills for future. Am I crazy? I wanted to ask in particular about your method of levelling the edges of the room first (C-shape). Would this be a problem for such a large space, as my edges may be too dry to work on by the time I have got round the whole perimeter? Any suggestions/advice would be much appreciated! Cheers

[@macplastering]

Hi Chris mate doing a large area is very hard and sore on the back and could be costly if things dont go right for you mate can I ask are you putting walls back in ?

[@macplastering]

and are you going to order in ready mixed gear or mix your own ?

[@chrismetcalfe4827]

@@macplastering Thanks for your reply, yes, we are putting walls back in but in more of an open plan fashion. If I went ahead with DIYing it then I think I would mix my own? That way if it takes forever I'm not stuck with several tonnes of going off screed. Do you think it would it be advisable to plan some day joints at sensible places, in order to take my time a bit more/save my back!? Cheers

[@macplastering]

@@chrismetcalfe4827 I would think if you put the walls back in it would give great places to stop as when screeding it is good to work of the bottom of the door frames that should all be set at the same level as eatch other. Mixing is hard it would be faster to have it ordered , the way if I was you would be have walls all in door frames set to height start in the smallest room , most mixing companies will give smaller amounts so you could give them measurement for that and they will work it out and add 10% just encase . But if you are heart set on mixing again start in small area give your self a chance at it ,youll get the feel of the hard work and the skills needed to get a nice finish thats level I am not trying to put you off but letting you know that it is not easy and i find bigger room harder to do in both skill and labour aspects , I will try make a Little video to show how i go about larger area. do you have to floor concreted and preped already as in insulation dpm ect ??

[@chrismetcalfe4827]

@@macplastering mac plastering under the existing wibbly wobbly screed is a concrete slab, uninsulated. Ideally I'd put some insulation in there but there is not much clearance with the front door, and ceiling is quite low. Certainly will be putting a DPM under new screed, whether it's a DIY or professional job :^) Great to have advice from someone such as yourself who really knows their stuff. I like the idea of starting in smallest room (bathroom) and going from there. I plan to self level afterwards to get a final finish for hard flooring. If I mix myself I was gonna borrow a mixer and have another pair of hands mix while I lay (that's probably a given). Thanks again for the advice 👍👍👍
