This has eased my smoothness anxiety😂 As a diyer, I’d have been panicking at the slightest hole / imperfection
Its not to bad on the undercoats as long as there is no massive holes hollows or bumps as the next coats are around 3mm
The technique you show at ~6:00 to plumb up the face of the wall is really smart. I'm watching videos to learn how to render/plaster bits on my house and I think that's the first time I've seen that technique.
Thank you buddy its a similar way I do floor screeds to get the levels. I wouldn't do it like this all the time as we tend to go for straight and the walls shouldn't be built to far out and again if they are would tend to need more work and time to get right
Great demo of craftsman ship mac not enough sand and cement work over here in the uk thx for sharing
Get asked a lot why not dot and dab why not hard wall but i think this works out the best way cheap and solid but yes the other options are great too ,, thanks for watching mate :)
You S&C like I butter my toast...smooth.
Haha could always be better I do watch myself while editing and say good man keep that hawk there catch the gear from landing on the floor less cleaning to do :) kinda forgot to say that in video but i am sure i z it 100 times now on other rendering videos no doubt ... thanks again for watching Noodles mate
Nice work Mac 👍
Thanks Anthony mate :) 👍
Nice work Mac. Thanks for sharing bud. 👌💪
No problem 👍Thanks for watching mate
I’m a DIY-er and getting to terms with this process. I’m pretty sure I’m trying to finish with the devil float too early and end up pulling more more cement off the wall. Just wanted to check how deep the screws should protrude and should I be resisting the temptation to close in the finish too much. Notice that at 8:21 you’re more concerned with a “general” float with more emphasis on providing the key. Almost at the stage where I’m contemplating closing in the finish and then using a scratcher. Sounds numb I know but I reckon I’m over doing it and overthinking too. Thanks for helping Mac
I preffer little thin nails myself - th-cam.com/video/-LRtsc0h17k/w-d-xo.html that me setting up the float ... The more you close it in the easier it is to skim. for sure if you go to early it will tend to stick in more and pull gear off or as some say rub holes in it, very bad for outside work as will make waves that the sun will show of... its mostly trimming here I can go early with experince but when i was learning i would have let it set up a little more and did the finger test poking it to see how wet and stiff it is
@@macplastering Hi Mac, Thanks for helping. I’ve watched the video and can see straight away that I had screws set way too deep. You have nails 2-4mm deep but I had screws more like 6mm maybe more. Plus I realise that the screws will have a tendency to pull the cement away whereas the nails will be a bit more streamlined. Gonna follow your advice and start again. Once again thanks👍
@lewigas290 I do know guys like the screws as easy in and out but thicker and like you say pull a little more. But yes always here mate 👍
Mac great tip on 🍑ing up your wall, corner 2 corner with the 1.8 box level
actually thought i had it recorded so it was 2 lines pulled off both sides if that makes sense but i either cut it out forgot to recorded it or just talked about that LOL but yes it is a good way to get walls much straighter and plumb again most jobs we don't have time for that its to go straight and plumb at window walls ect sutch as sites and some walls you would never get right unless you had 3 days at the wall LOL Thanks again for the support Joe mate
Hey Mac ... Have you got any 'Moran's' in your lineage?? .... I used to sub off of an Andy Moran - A lot of your face-shots in this video - You do have his look - And he was Irish - Bought most of Ireland with his profits 😄
None mate sorry he must just been a good looking guy I think :)
🔥🔥🔥🔥
Thanks mate :)
I would bed in some render mesh over that timber wall plate and the wall straps to help any cracking from occurring.
For sure be good mate but yea will be back here doing floor and can show it all off cracks warts and all as they say doubt it will have any but then again even mesh and fibers in mix with sbr wont stop it if it wishes to crack :) again done it both ways and seen it be fine both ways also see it crack both ways never seen a steel brace crack mined you or never noticed it again always make sure they nailed tight
i love the sound
Hi thank you is it the sound of the tools or music ?
Good video buddy! I love how it's standard practice to get loads on the floor haha when do you pick that up anyway? Before it sets?
No let that stuff set for a week or two then hire a drill to chip it up LOl Jokes mate I think if you re watch video I forgot to say during it to keep the hawk / hand board under the trowel if you look again you will see the gear dropping is caught my apply to drop ratio is like 10 to 0.85 haha no but in all serious when im straightening that gear is back in the tube board bucket wheelbarrow also i keep floor clean so can pick any if any that has feel and re mix it :) Thanks for watching Marcus mate
I’m the best amateur plaster catcher in the north!😂
@@lesleywillis6177 worldwide lol
I want to know what exactly is that, you used in straightening the walls? Was that just an ordinary plank wood?
No it's a refina aluminium straight edge and one was a Bix level
what additives do you put in the Render and is it the same mix for internal and external sand cement
Most times, different mate as outside will have waterproof in it and inside don't need it
Again so many different types of jobs new block old block red brick ect
thanks for the advice ive only ever used hardwall and bonding on interior but i was intrigued by your interior sand and cement plastering because i believe its lovely to get nice and flat even though it might be abit more messy thats why i was curious as to what your mix is for interior sand cement old brick walls
most times 4 to 1 with some plasticizer in mate i would find bonding messier as if floor is clean you can re use and cement of floor
thanks 👍
If the wall was all over would you put a scratch on first to get it something like straight first?
Do you mean all over the place ?
as in really bad shape ?
Yeah not plumb and old brickwork.
@@mrwright5699 Yes like some of the new builds these day LOL so if it is really bad and heavy it would been a scratch to build out then next day would need a top coat like this mate :)
Hey mac I’ve always set up goal posts when doing my floating work, is that something you ever do?
Have you got any videos of setting up backing coat beads?
Hope you’re well mate 👍🏻
No hate at all mate love your craft but did I miss the 1st scratch coat, I was taught 1 scratch then top coat n float it then skim, do u ever have a problem might save me some time in the future 😂❤
No need to scratch coat if wall isn't to bad shape scratch for inside would be over kill unless like i say a heavy door frame or bad shape wall but yes you can do that it would work fine but a good 10 12 mill on be perfect I have a clip of this all painted hoping ot get uploaded all thought the guy painted WAY to early but if will still show that no block shines through ect Thanks for watching and commenting mate oh again if I could get more money to do a scratch coat on every wall i would 100% :)
Sorry if I missed it. What’s the ratio you use inside?
This one was 3 to 1 on the scratch areas then 4 to 1 top coat mate
I was taught 35+ years ago to sand and cement was always right to left and skim left to right. So it stuck that way for me
Ye it seems to have for the ones who do sand n cement do as they where showed as long as it well push on its grand what way did you coat dry dash receving coat mate?
What’s the advantage over sticking up some plasterboard, cost?
Great question buddy Would it be good if I did a little video on this talking about that and my views and points ect ???
@@macplastering yea do a video on it Mac.
It can come out more expensive on smaller internal jobs in houses being used, if your taking into account mess and preparation. Cheaper to use plasterboard then and cleaner.
Probably best I don't comment!
Thats already to late LOL
@@mc4067 exactly
You are master but You forgot to moisten the wall with water 💧 Increases adhesion properties
Low suction wall if I wet it would be bad in this occasion as wont set nicely if was hight suction yes would wet it down on scud coat
Ha ha for all you haters out there mac no matter what you doing someone will always have something to say 👍
For sure mate I only think i fussy haha no to be fair most the viewers are brilliant like 99.9%
Could this support porcelain tiles? Seen the lads in America float bathroom walls with mesh…
Curious as gypsum is only rated till 20kg per sqm. I know this is render but some old properties the skim is over a render as you have done
Depends on the size and weight of the tile we do tile over this here with no issues untill tiles need removing takes the skim with it but you could just float it and then tile would be the strongest bond
@@macplastering some good quality porcelain probably 35kg-40sqm with the adhesive and grout
best to do a little test before fully committing to it mate
@@macplastering will let you know how it goes, will try it on a future job
yes mate
First plastering I see going on from left to right
really every right handed plasterer i know from belfast and more dose it like so
Wire mesh is definitely a good way to go then scrim on floated wall...... Try going the other way mate when floating and a right hander, your building it out your not skimming
@bensharpe370 fir sure on the mesh why I talked about it but I love working left to right it's so much better and comfortable qustions fir your self when doing a dry dash coat you work right to left. Then do you dash where1st ? The right side? Also same when rendering when you rub the wall where do you rub 1st ??? Do you rub right to left as its the way your gear will be drying most?
@@macplastering mate!! Im really trying hard to understand. Right hander left to right on finish plaster (your not building up anything) right hander on any backing coat then (right to left your building it up). When you say what would you go on first as in dry dash, with all due respect it's what you put on first. The only reason why you have questioned this is because it's easier for a right hander to dash it from left to right. Show me a floor screed, I need to know how you do that.
@@bensharpe370@bensharpe370 my point is it don't matter where you start when building up its where you feel best also for your outside work it actually helps more this way as when finishing it is easier to see your work.. we have loads offloor screed videos or is it on walls your looking for? Strighting up?
@@macplastering fantastic plasterer mate keep up the good work. My boys in Corfu at the moment he's 18 (first holiday abroad) can't tell him shit he's knows best. Typical teenager, you got any kids.
@@bensharpe370yes I sure do have kids is your boy plastering in corfu ?
Right handers work right to left , lefties left. To right ,,, toe ,,,heel of the trowel.... just saying......
not all right handers do some work left to right as i just showed and most right handers i know in the game do to and great plasterers funny i know a left hander and he dose opposite this is toe to heal pressure is key not really where you start i could start in the middle and work a spiral out form that and it be just as good as any wall LOL I do get what ya saying as a guy wrote it in a book before but fails to say where his foot work is and how his body is shaped in fact has anyone ever said that ? the other thing you have to think about is dry dash no way is a guy that dashed right hand gona go and start right to left the start dashing left to right as again how you would be standing and flicking the stones on another thing really missed in the old plastering books think its time they got a new write better still it could have been a typo LOL but yes just saying and do what is most comfortable as to prolong your energy and work life my friend
@@macplastering so defensive..... Unbelievable
@@bensharpe370 not really
you started from the left!
Correct
@@GaZonk100 I know
Most of it is on the floor.
Lies
😂😂😂 I can only understand half of what you're say. Sorry pal.
Half is better than none lol
@@macplastering Hahaha 😆 😂 🤣 😅
Same here ... had the brainwave to turn on automatic captions but that was just hilarious!
