I was always told to two coat plaster. There is a massive difference in the finish. Great video 👏
Totally agree with you on this mate… 2 coats for show, 1 coat for dough 💷🤑🤠
@@stephenmillar453 a good one too 🤠😅
I've been plastering for 35 years,when I started walls were float and set ,skimming cement walls you need 2 coats ,today everything is plasterboard,all I ever do is 1 coat on boards lay on with steel ,flatten with ox plastic ,then 2 wipes with nela an a splash brush ,perfect every time

@@stephenmillar453 can you explain why?
@@kxjx read the bag mate
@@stephenmillar453 I read the bag, so I always put 2 coats on. But if his one coat results is good.... like I dunno I thought you might be able to tell me something about what problem it would cause or something... anyway doesn't matter.
Hi Alex , A 40 year plasterer here ,just wanted to comment on plaster in the eye , happened to me a few years ago trowel full in the eye blind for 5 days , it burns like acid , be ware .
Had same it fell in my right eye struggled to see following day now wear them safety specs when doing ceiling not ideal
By far the best and most comprehensive plastering tuition channel
This is a great video. I use one coat and two coats plastering. On lovely flat new boards one coat is fine as long as it ends up 3mm thick. . On an old house with damaged walls two coats can really help sort a lot of problems before you put on the finish coat.
Both techniques are good . Different situations call for different techniques.
Keep the great videos coming. 👍
i learnt 2 coat plastering, after 2 years i went to one coat and have done for 13 years never had a call back painters love my work customers love the work never had a complaint ever, cuts time doing alot more work in one go if want. if your replastering old walls by all means 2 coat unless you built out bad bits then skim but other than that one coat all day, still the same finish some people just cant one coat cause you learn 2 coat
Very nice . Just wondering if I want to do a 1 coat wall onto painted wall good condition do I have to put some sort of gripping agent on the painted wall first cheers in advance.
@@nathanevans6331mix 1 part pva to 3 parts water, use an old 4pint regular plastic milk container. Brush or roller it on and wait 10 or 15 minutes for it to dry then put another coat of pva/water on, wait 5 or 10 minutes for the wall to go tacky, then your walls ready for plastering, it's a must because it bonds the plaster properly to the surface of wall and it stops the plaster drying to fast and cracking, better to be safe than sorry.
dan solo got a very good explanation on why sponging is wrong
Great vid Alex I generally 2coat but there are times when I have one coated and sponged and got a good finish. Totally agree with what you say about the traditional plasterers ‘spongers ain’t plasterers crap’ you can say that about any trade when I first started out the old boy Chippeys never had all the cordless tools and chop saws just literally a bag of hand tools and saws they actually sharpened themselves. So yeah if your finish ain’t compromised and you get a good finish using a sponge why not if it makes your life easier 👍
Brilliant, I've used the one coat sponge method now for 30 years, I'm 60 now, it's a perfect match sponge and spatula, especially for mechanical plasters
I bet your body is thanking you now.
I’m not a fan of 1 coat on massive hits. 70 m² ⬆️ but I think it’s alot easier.
I've been plastering around 15yrs always just used one trowel and one coat of multifinish. I do use a spray bottle but never used a sponge, a spatula/speedskim or a flexitrowel - Never even knew they were a thing until recently!!! I'll admit I do get tiger stripes every now and then but walls are flat and you don't see the stripes once it's painted.
get that meterage on lad!! lol!! ££££££
@@jb-78 you know it!
They use to call my old boss streeky bacon ron lol
🙌🏼 thanks for the mention Alex 👍🏼
Will let you know how I get on once this dorma is insulated and ready to go
I have always done two coat work but I am thinking of trying this on my next job, I have used the sponge before and it works really well and after watching your video I can definitely see the advantage, thanks for sharing
One coat all the way I want to get home quick ☺️
We try to 2 coat most walls as we just find it's a flatter finish. But we sponge that also, just for the reason it dries more uniform.. And as for your point about bg not recommending sponges they also dont recommend using pva and we all do that also.. 😁. Good video Alex 👍
They also recommend 12.5 litres of water to 1 bag of plaster, far too thick it’s unusable 🤣
1 coat or 10 coats it's all about application at correct thickness..
Fill out your beads and get it on..
Flatter you can lay it on the better
The rest is down to timing.
If u get it flat enough on good 1st coat u dont need alot for 2nd timing and a good trowel IMO .
Was taught old school way long time ago just got back into doing a few walls here a few ceilings over artex
The little jobs no one wants loving it not greedy just earning 👍👍👍
👍
Most plasters here in Ireland put 2 coats on with the one mix. And sponge float. First time seen Alex doing 2 coat with 2 separate mixes and flatten between coats, looks great 👍
Been plastering over 20 years, never one coated, always 2. Got a sponge the other day and found if I give it a go after flattening I can get a nice finish. Got a Refina fine sponge. Dunno if a medium would be better though. And yes, cleaning them is a pain.
Just another thought. This really could help get us work back from the taping and filling teams. It must be cheaper and quicker then getting them to come in three times. 👍
Each to there own bud everybody does it a different way but as long as the results the same crack on great vid 💪🏻👍💪🏻
I'm currently doing my level 2 NVQ and one coat plastering is something that was massively frowned upon by my teachers. In the coming months, my NVQ assessor will be coming on-site to assess me for my NVQ and if he spots me applying one coat, he will definitely fail me. Interestingly a friend of mine works on building sites in London and apparently it's now standard practice to apply one coat of plaster on new builds.
My best advice would be to stick with 2 coating until you have more experience. Learn the tradition way first then you can experiment with little tips and tricks. Alex is by far the best plastering channel so if I was you I would literally study his videos. Its actually mind boggling how little subscribers he has to be honest
@@eoinob Thanks for your constructive advice.
Great trade to be in. Well done. I agree stick to two coat tbh. You will get the most consistent results.
1 cost is handy to know to gain extra m² and to save on a bit of time. But I wouldn’t use it as your go to method, unless all your doing is board work on site.
Learn the traditional way first; then add experience by using different techniques.
@@AlexMorleyPlastering Thanks! I really appreciate your advice. I'll stick with the 2 coat plaster and traditional methods for the foreseeable future, then after earning my NVQ I might experiment with other methods to improve my productivity. ( I still haven't used a spatula speed skim or sponge as they were not encouraged by my teachers. I did the entire procedure from beginning to end with a stainless steel Marshalltown ). PS- I massively appreciate all your videos and I would heartily encourage you to keep up the outstanding work.
You will come realise in time that site work is all rush and tear and no finesse.. I'm a chippy of 30 years and I walked away from site work years ago I couldn't stand it. It's all who can do what the fastest no matter the quality of finish and personally I take pride in what I do.. It will be good for you to learn meeting lots of people and will certainly keep you busy, tbf It's probably not so bad for a plasterer but as a chippy people nailing stud walls to the screed with a paslode and sticking kitchens in with gripfill is just shocking. I wouldn't wanna buy a new site house I'd see all the imperfections 🤷♂️ good luck mate and enjoy your job and have some pride in what you do, it's not all about the money tho it is nice 😉 👍
Well said pal ..
nothing wrong with sponge. Been spreading 35 years and can do it all. And what I’ve learnt is ……
Always make the Painters job easier , then you’ve succeeded and your a decent plasterer.
It’s irrelevant how you did it.
Know one cares . Except the painter and client.
Enjoying the videos , I am a plumber and i price by the job not how long it takes. Why should we suffer because we can do the same job quicker. Show Buisiness not show Friends .keep up the good work 👍
I personally don’t use the one coat method but I don’t tear it down for the simple reason being….17:30 exactly!! I can’t show you that evidence and neither can 99.99% of the other plasterers in this country
All depends on the man with the trowel in his hand. Plenty good 1 coaters about
Bang on 2 coats around the beads bang on 2 coats until that last couple walls and you second coat Same mix and last wall gets a oner . Sponge floating is balls just flatten immediately and add a second wet trowel . Timing timing 👍 I am old school old guard trained and trust we all any of us have ways of doing
I do both depending on job You can make just as good job 1 coating Iv done it plenty of times infact did it Friday 😁 Iv never had a come back on jobs
Ive plastered for 20 years. 2 coat for few years, then 1. Gone back to 2 coating. A few pals have been sponging... Ive tried it. Like it. Fuck 2 coating. Back to 1 and a bit of sponging. Yeaaaaaah.
Good demo. Thx.
Seen this method many times, and that was a good example. I tend to two coat with the same mix, then use sponge float. Is this ok?
Works well that method. We occasionally do that also. 👍
Very informative video!
At 17:11 when you said you had a second coat of skim fail on you, what does that look like? Lots of shrinkage cracks? The second coat curling/falling off? Crumbling of the plaster?
How things change EH?? ...... When I started, (Traditional) plastering would be a 'Three - Coat - Finish' ....... Steel Float - Wooden Float - Steel Float ...... Then just as it was tightening up a wet cross-grain-float (wood again) would be used all over, much like a Sponge-Float these days. It would also be used to make sure our internals and externals (pre-metal beads of course) were absolutely Spot-On :-) ........... Finishing Sand & Cement Render and Board ...... I think one-coat can be successful these days because of the quality of the 'fixings' - in our days the boards were all over the place, and we used Four sand - One lime - One cement for our rendering which gave a 'lot' of suction. You would never get away with one-coat back then with the materials we had - No Multi-finish until the 80's/90's - I think ?? ..... And the promotional BLURB from gypsum was that it 'could' be used as a One-Coat finish (Not that I ever did) and could still do two houses a week on my own :-)
Trowel float trowel guy who taught me used to do if haha
Peter moring
Salute you pal
Wat dolls houses
Hi Alex , great video thanks.
Where did you get those tickler brushes from? they look really good.
Wickes and think. They are pretty easy to come by. Just a cutting in brush.
I do 9 coats, 2 vests and a bomber jacket. Not sure why, looks shite.
🤪
Your exactly right 2 hits a day on 2 coats is more than enough im 60 and still banging um out good on yer
Speaking from a man of experience. Thanks for your comment Lee. 👍👍
Good video we put 35m2 to 40m2 one nan sets on. When we sponge we only sponge say a 1/3 of the set then back and take out the lines then next 1/3 and so on . That way you can put decent size sets on and sponge no problem. Going to give your method a go though
Great suggestion. Thanks Michael.
Not nan man
Why does it need to be sponge float if only doing one coat?
By adding moisture to the plaster you improve plasticity. Giving that you are using long soft edge blade (as long as you can fit on the wall - 2400mm on big wall or ceiling!) you can achieve almost perfect flat and smooth finish. Never use small trowel on large surface with single coat as it only caused dents and imperfections.
NVQ’s..my father was a senior lecturer for over 40 years..taught City&guilds in engineering/tech drawing/maths/computers etc..always referred to NVQ’s as not very qualified..🤣🤣🤣
Was going to try but struggling to get 1 coat on before going off
I’m newer to plastering (finished college and had site experience for a year) I’ve moved to a new company and they want me doing 1 coat finish which feels weird to me but seems to be the normal now I’m up north from London (I’m a decent plasterer and do get a good finish) I have 3 ceilings to do on Monday so would you recommend I start using a sponge float due to the company wanting 1 coat? I have a refina sponge float, I also use speedskims, flexi trowels and so on
I wouldn’t start 1 coating unless your going to use a sponge. You will need a sprayer too.
@@AlexMorleyPlastering it all worked out well and the finish was spot on, cheers for the feedback
Alex we all do it but I wouldnt broadcast it on here as people are anti 1 coat JS
Hi Alex great work, was just wondering which angle trowel or as you would say twitcher do you use on the corners, is it Ragni??. I have been told the Ragni angle trowels are better than the Marshalltown one's, What do you think.
Definitely the Ragni. I have had the MT. No comparison
Brilliant mate thanks again. 👍
Call me a cynic but maybe British gypsum insist on two coats because ur using more of there product that way .most things in this life come down to the dollar I find
True but at the same time the proof is in the pudding. There are many times when the overall finish is demonstrably better w/ 2 coats as opposed to 1.
@@nicholasberic947 yeh I gotta agree but I’ve found u can get a more than acceptable finish with one coat sponge floated and then troweled up to a finish I’ve done it on numerous occasions and there really isn’t to much difference between that and two coats
Also can you do a vid on how you protect you iPhone speakers 🤣🤣🤣
My phone is currently in a sandwich bag.
Plaster kills iPhones 🤣🤣🤣👍
Oh yeah! I get it in the charger port -speakers lol ! I’ve not long had an iPhone 13 pro and it’s FUCKED ha ha
Just read what it says on the back of the bag.. that is the correct way.
What happens if you one coat, flatten and trowel without the sponging and going over 3 or 4 times with a spat?
Can't believe it is even a discussion
Easier to do walls than ceiling and around patio doors
Whats the difference between 1 coat and using spatula and 2 coat without sponge float
I got tought to always do 1 coat onto board
Another good vid Alex, how’s the nela trowel coming along or you not really using it at the moment
Yeh it’s going ok. I actually laid this on with the giveaway. Just troweled up with the cement trowel.
@@AlexMorleyPlastering ah nice I’m still using mine start to finish had it about 4-5 months now leaves a lovely finish now
Interesting, hard to tell on a video but one coated walls looked a little lumpy bumpy to me.
Personally I’ve found when I do it, you can get the walls lovely and smooth but never as flat as two coats!
Nice comment. Thanks for your feedback. It’s the plastic trowel that gives that appearance. I ran it over off cameras. It looks like bumps when shining raking light on it.
A better example of this is in this picture on our instagram page.
instagram.com/p/CLXkGxxBoyv/?
If done right there is no difference, but the surface needs to be really flat before skimming....otherwise 2 coats are required and even with 2 coats if the walls/ceilings are not flat/straight then the finish will be quite poor when throwing a light under the wal....all the best ....keep the videos coming Alex
was just replying to dan solo replying to you but now its gone? did you remove his comment?
no. your comment is still up. I have seen Dan’s video on it. that is just opinion. nothing in the comments to support what he is saying unfortunately.
Hi Alex. Love your videos.
As a DIY'er, I'm liking the sound of one coating to take the pressure off by not having to make a second wetter mix.
Do you have to use a cement trowel to flatten or will the Marshall Town Permashape laying on trowel do the job?
Thanks.
Never use a trades person who dismisses new techniques without a reason…
This is the thing, I've never had any plasterer not look at me confused and without an answer when I ask "what's the point of two coats?". You can tell they're making up an answer on the spot because they daren't risk admitting they might not know it all.
i bought a refina sponge and the sponge just came of the trowel within a few uses. used a spray carpet adhesive to fix but still.... wasnt impressed
Alex, how much would you charge for skimming out that garden room?
This was on a m² rate. I’m this case £8 m². Both rooms came out to about £460ish
@@AlexMorleyPlastering that’s cheap! I wouldn’t plaster one room for £460
My god £8, that's mental, we get £2.50 where we are, full 2 bed houses gor not much more than £460. I need to move!
@@liamjackson9399 😂 where the fuck do you live?
Haha 1975 by the sound of it 🤣
So will mixing gear in dirty water effect the rate in which the plaster goes off? And what is your take on using of date plaster? Does using out of date plaster cause the plaster the go off quickly?
The problem with both of those methods is you can’t modulate the rate it goes off. It’s all or nothing with dirty water or out of date bags. I’d use half time tbh if you want to shorten the set.
Dirty water, out of date plaster, plaster that has a tear in the bag warm water and mixing to firm then adding more water and mixing old gear in with a new mix are all things that will accelerate the rate in which plaster will go off and it's so hard to know just how quick.. do any of the above one minute it's alright the next you go back yo your gear and it's gone, all these things can get you in a world of s#!t. A lot of plaster lately seems to be going off double quick as it is I've experienced this as have many others 🤷♂️
What's that spat you use? He handle looks much comfier and more natural to use than the ones I've tried (and subsequently discarded because I didn't get on with them)
Think it’s the refina
Yeah the Refina, so much better than the speedskim, grip wise and the fact you can get right into the corners whereas with the speedskim the handle gets in the way at times
Hi Alex, would you recommend only using the one coat sponge method on plasterboard ? or can you do it on other surfaces Great informative video on timings etc once again Alex
Tbh, we very rarely use this method tbh. The video was created to show the comparison and the pros and cons. Generally we only use the method when we are trying to squeeze extra m². However I wouldn’t use 1 coat on much more than on board, or reskims where the walls aren’t that bad.
When you going over Blue Grit or rough walls you have to apply the plaster so thick it makes it difficult to do a good job.
@@AlexMorleyPlastering thanks Alex
I'm a old school 2 coat plasterer ( at least ), 1 coat isnt proper plastering in my opinion
Old school plastering never had boards like we do now, board finish at 3mm is fine and you wouldn’t know any different between one or two coats, stood infront of 40 year old timers and had them baffled at which coat was which and they didn’t have a fucking clue. That extra 30 quid a bag makes all the difference though, can make one bag of plaster stretch 20m and that’s nearly 80 quid a bag 👍
So how long did this. Job take ?
Paper tape is way better. Btw, how tall are these ceilings? No stilts, and barely reaching on an 8' wall and ceiling.
Never done it!!
I always do just one coat, don’t bother sponge floating. Don’t really bother troweling it up just give it a flick over with the trowel. I also just lay on and do the whole set with a flexi trowel, painters are always moaning at me about the finish being crap, I really don’t give a darn.
It'll sand..
Is that dewalt light any good,? Maybe review for that.
Incredible. Best Buy of the year. We will be doing the review in the next few weeks.
@@AlexMorleyPlastering cool I may grab one myself is the battery life any good?
@@elkatron4410 if i could go back and start my battery / power tool collection again id go with makita simply because dewalt will rinse you for every penny just off the name whereas makita are beating dewalt everytime on price and the kit is top notch.
@@nobbystyles4807 Makita every time!
What spatula do you use mate?
www.refina.co.uk/hand-tools/plastic-trowels-floats/plazi-spatula-rules.html#/172-sizes-32_800mm
What opinions on felt brushes, I haven't seen videos on them
Tbh I saw them when they came out a few years ago. A bit of a gimmick imo. How to you brush the skirting line and corners ect. Just another thing to carry around I think.
I’ve always wondered that. In the old videos of the US plasterers you see them using an amazing technique with it, but like Alex says, how do you bring in the corners and ceiling like etc
@@NiktheEnglishGreekCypriot I use felt brushes, trust me they are a wonder to use. Used them when I was working in Boston, they create a type of fat that you can slide your trowel over, been using them for about 12 years. I do sponge now and then, but to be honest, I one coat, double back with the same batch, fatten in, leave, spray trowel, leave then felt brush, leave again then cross trowel with a 16 inch Marshall town Flexi, job done. 2 and a half hours max. Can get about 2.15 on a good day.
@@jimjimskimmer1935 cheers mate, I’m debating buying one, are they easy to maintain?
@@jimjimskimmer1935 What is spray trowel?
I see you have a cough, try gargling with cider vinegar at the end of the day, this may help
Yep. Been struggling with a cold for a couple of weeks. We had to get a school finished in a short time. So worked through the weekend. Can’t shake it at the moment.
How about a video showing no sponge no water no sprayer just timed to perfection fist coat then flattened off and then second and then flatten and then Trowelled off . 🤔😉👍.
For that you wanna watch Dan solo.. the guy is old skool and an absolute machine!! 💪👍
Dirty water, cement/ bonding, 1 Coat 🙏😜
Give up mate can’t put anything in a finish coat maybe get away with a bit of cement but fuck the bonding
Come on we all know the answer to this
would you say the mt’s are better than the nela carbon?
Out the box. MT Cement currently. Not the 13” plastering version.
Fully broken in. Not sure. The NELA is unbelievably good.
@@AlexMorleyPlastering been breaking in the nela 13inch for 4 months i love it, still not sharpe yet. just ordered both the marshal trowels you’ve just started using also,
I like this chaps videos ..... but talk about tearing the arse out of it ...
4 coats it better
5 coats makes it even better, it keeps the house propped up and strong for longer!
@@robowen66 and warm
I bet plasterers who hate on 1 coating still haven't got over being told to show their working out in school..
If you get the result, who cares how it's achieved?
