The best place for one coat plaster is in the skip.
As for getting your plasterer back, I wouldnt bother, get one who knows what hes doing.

I have been using universal one coat for years ! It was used by local authorities and my last big job with it was an extension to a lifeboat station .
Walls had to be finished to exactly 14 mm depth . Was tricky at first but soon got the hang of it . With the correct tools . I challenge any plasterer out there that I can one coat a wall and finish it as smooth as pink gypsum , quicker than they could float and set the same wall to the same depth ! I have been in the trade 30 years and been using it as long as I can remember . Without one comeback !

Hi,
i sometimes use one-coat for patching up small holes or for repairing plaster around electrical sockets and is perfectly fine IF you know how to use it properly but i would NEVER re-plaster a whole room with it.
If your re-plastering work was done from the brickwork,looks like your 'plasterer' has tried to cut corners big time,but if he has used it for re-skimming,then that just beggars belief!

My advice:
1.Don't call him again.If he can't do the job right first time..............
2.Get someone round who truly knows what they are doing.

Good luck with everything.
Hope this helps,
Carl.

Hi There I'm a plasterer living in the norfolk area most of my work is in old 1800 + year old houses cottages some of the clients prefer universal one coat which basically means only 1 coat is applied usually from 4mm to 11mm to be honest it looks ok in a old cottage type house some prefer it to be brushed in for the old rustic look I hate it personally as for pink multi finish golden rule is always use 2 coats and ensure areas are brushed or rolled with a pva solution and all should be as smooth as a babies arse the bags of one coat are more expensive and the finish product is no where near as good as multi finish regards tim

Big massive NAW, multi finish if skimming 1st coat then a laying coat and polish up,wouldn`t even use 1 coat on ma enemies walls ha ha ,you see a spread bringing it out a van lock your doors. PS i`ve been plastering for 30 yrs

No a pro plasterer will not use one coat, they will use pink gypsum or similar, and apply two coats.A lot of DIY people use one coat.You will need to get rid of the one coat and start again for a pro finish

Agree with all the above. Would never use the stuff. Always Thistle multi-finish and apply two coats.

Never. Only Thistle multi finish plaster

Hi, I've been plastering for nearly 16 years

Basically one coat plaster was brought in for new housing developments for speed ... if you are plastering over plasterboard lafarge universal one coat is perfectly ok to use.

But if you are replastering walls, you have to use thistle multi finish two coat plaster.

I think the saying goes ..."horses for courses"

2 coats of multi finish only.......not 3 this is wrong... if your walls are bad. you use bonding or hardwall first....

HI, in answer to your ? is no always use two coats lay first coat on tidy as poss then close in top coat kind regards rigsby.

Hello, number of plaster coats depends on surface you have to cover really. Generaly we can say 2 coats give you good finish but sometimes even 2 are not enough to cover uneven surface. 1 coat - hmm... I've seen this couple times and the results were not bad but efforts to give nice finish were even harder when using 2 coats technic. I strongly recommend 2 coats as a base - if surface is still not nice - do it again (another coat) - whatever you do - do it properly - once for life.

Hi there Ive been plastering for over ten years and I wouldnt use it ,I have use it once but then had to cover it with normal gypsum finish.

I have to agree with the lads on here, one coat is for the diy er.
The rule is proper prep of walls first ie a bonding coat or similar.
Control the background with pva solution if there is a lot of suction, and then skim in the usual way 2 coats of finish plaster either muti or board finish, I prefer board finish as its a better quality than muti but that's just my opinion.
Sounds like you had a lad who don't really knows what hes doing, I would try and get your money back, but pigs might fly.

Good Luck

I have been plastering for 30 years and have used the one coat system On a quite a few occasions. this system was designed to be machine appllied by spraying it on, and building it up in layers , you can get a good a finish as the gypsum finish but you need to have been taught how to use it correctly. I used it in Germany were site were set up to accomodate the spray machines,
it would be to much hassle to set it up for a small job in the UK. Best to stick with what you know how to use in my opinion.

No qualified plasterer would you use one coat it is normaly used by DIY users on small patches

we would never use this method all good plasteres should leave a finish of good smooth condition ready for emulsion or papering

Dont pay if not happy get carried out correctly !

Hi
I've been a plastering contractor for 14 years commercial and domestic had lots of plasterers of all abilities working for me and none have one coated .

I'm not saying this is the case and there will be a hell of alot a spreads out there who agree with me ,there seems to be slot of people in recent times who fail to realise what hard work and dedication it takes to master this trade and along with that we require a certain rate of pay which is well deserved.
Some customers simply won't pay it.
ENTER our £80 a day one coater from the pub that takes 3 days to ruin a 12x12 room

Like I said im not saying thats the issue in your case but hire a pro with good feedback or your able too view recent jobs he's done.

All the best hope your sort things.

Kind regards Lee Eaton

All these so called plasterers and they cannot use thistle one-coat plaster it's a brilliant product if you can use it.
It's completely different system to thistle multi finish, you still lay it on the same with 2 coats it just covers thicker without issues.
But primarily I would only use in a period property normally.
If it's not done right it will be rubbish. "chancer's" don't stand a chance unless taught properly. If you want a plasterer they should be able to do it... If you want a skimmer who can only skim (basics ) then expect issues I say.
All the best

Hi there

Any professional plasterer would in no way use one coat plaster. The reasons being that you will never get the true fine finish that is required and will usually get the finish that you have received.

Personally, I would always with no exceptions 2 coat any room, wall or even drywall repair. One coat means the job is obviously completed quicker, however this very much is a 'lazy' way of plastering and should not be done.

Hope this helps.

Hi, any professional plasterer would use thistle multi finish, one coat plaster is used by diy ers , who only do the odd bit of filling prior to decorating.

If you speak to a mate of mine who works for knauf, he'll say why not give one coat a go ? I did.....as a professional plaster used to working with thistle multi-finish, i found that the drying/going-off time varied considerably. All pro plasters will say work with what you know....i would never work with one-coat again.

Hi, I am a property maintenance guy and a domestic Electrician, I only use one coat around the sockets/switches that I have had to install unless I know a plasterer is coming in behind me purely to protect the cables from being pulled back out the wall. I wouldn't use it for a whole wall as it would terrible and would need to be re-sanded/skimmed anyway. Even the plasterers that I use pink thistle stuff as it looks much better when it has gone off and it means that it has been done properly, it is an art that needs to be mastered

I personally would'nt touch one coat. Always multi finish applied in two coats.
Dont bother trying to get the bloke back!! Did he give you a written quote, if so demand your money back. If the wall is salvageable try using fine sand paper on a block and give it a light rub down, getting rid of trowel lines and wobbles etc...

Good luck.

Hi no way should a pro or amature plasterer do one coat or use one coat plaster,ask for money back,get a pro plasterer,who applys two coats,good luck.

One coat is for plasterers trying to get in and out quick. It could never have a 10 year guarantee. The second coat plays the main part in making a wall truly flat and even. 2 coating is far more durable. 1 coat needs a lot of water to get flat which then weakens plaster also.

I've been plastering for 8 years and not once have I been tempted. Multi finish all the way unless you've got a small job on and then I use board finish as this tends to go off quicker. Theres a lot of truth in what they say - if its not broke, dont fix it!

I would try and contact the bloke, if he values his business and customers he should at least help rectify the problem.

Hi Simonewt
In response to your question regarding onecoat plaster its a definant no go this sounds like the work of a chancer,best bet is to have walls reskimmed with two coats of gypsum multi finish preferably not by the same person who did it originally, just a shame you've had to waste time and money in this way good luck with it.
Regards Dean

As above, always two coats, and a sign of a good plasterer is the finish that is obtained around sockets corners and such, along with finish on walls. One coat is for the rip off merchants, and there about. How much were you charged?

Hello,
In my opinion i would always use gypsum multi finnish, the finnish is so much better than one coat and its also cheeper.
Hope this helps you out
Many thanks

If you know what you're doing there is no better stuff...with experience you can get a marble finish...however I've dropped every clanger going till I got into it..

Some plasterers do two coat and the end result is rubbish. Some do only 1 coat and result is rubbish too.
I personally do one coat and result and finish is great every time. It's all about skills and technique. I don't have any plastering degree. I have learned the one coat technique and practiced it and master it.

hi,one coat plaster is normally not used by decent plasterers as it is generally designed for DIY purposes and you would not get a finish which is as good as multi or board finish which is sipplied by british gypson.

No no no very bad stuff. crap finish. paul

Two coats of plaster is a must for a true professional finish.If your going to do a job do it right especially if your doing it for a paying customer.

One coat plaster will only give you half the job that your paying for and should always be done in two coats of multi finish. Put it this way I wouldnt have it anywhere near my house

I for one like most other real plasterers I know wont ever use one coat for patching nevermind a full room.sure we have all most likely tried it at some point for small patching work ie around sockets etc but it should never of been allowed to be on the shelves in the first place.bin it or even better uninvent it lol.no self respecting plasterer will ever use it and as for the plasterer whom used it then please what ever you do do not I repeat! Do not get him back .

I would say one coat plaster is for someone who isn't a professional in the plaster trade unless it was specified by the customer which you can only advise otherwise

One coat is not good stick to multi every one uses it and it's guarantied the best plaster to use

Two Applications of multi finish is always the standard. (A pro should know).

i have heard of it but i dont agree with it i would never consider putting any less then 2 coats on as your first coat is about 2 mm and that evens walls out your second coat is about 1 mm and that gives you your nice smooth finish i would not employ someone who uses one coat even if its a thick coat 2 or none

One coat plaster is only for for diy use no tradesmen would use it if there good at there job

Never use one coat plaster its for diy's always use a 2 coat system of thistle multi finish or board finish never one coat plaster it's for cowboys

A.OXBOROUGH PLASTERING & TILING

2 coats always multi finish. No decent plasterer would ever just use one coat

One coat plaster is poor should always be 2coats to allow for coverage to fill in any misses or discrepancies on the wall to ensure a high quality finish

On the plasterboard should be all the time 2 coats. Otherwise you not gonna get nice finish.

Always Thistle multi-finish and apply two coats. Basically one coat plaster was brought in for new housing developments for speed ... if you are plastering over plasterboard lafarge universal one coat is perfectly ok to use. But if you are replastering walls, you have to use thistle multi finish two coat plaster.

Hi there, 1 coat plaster should never be used it is a terrible material, 2 coat process is in my opinion the only way in every case!

Never use one coat plaster its for diy's always use a 2 coat system of thistle multi finish or board finish never one coat plaster it's for cowboys

In my opinion i don’t recommend one coat plasterer. Always get a better job when using muilt finish or thirst board finish and doing 2 coats of plasterer.

Never one coat that’s not the wright way that’s the layzey. Way

You Always get a better job when using muilt finish or thirst board finish and doing 2 coats of plaster

No I wouldn’t use that stuff only good place that belongs is the skip. Only Thistle multi finish plaster that I would use!!

Any plasterer that knows his trade would never use one coat plaster on walls
Multi finish gypsum is the best for plastering and he should have known that so I would get some different

I have used one coat plaster on many occasions there is nothing wrong with
The product at all if you cant use it
And you are a plasterer then the best place for your tools is in the skip

To keep it short and sweet, No. Professionals would not use one coat to plaster a whole room.

No one coat . Two coat all the way

This is certainly not a common practice, this guy is a cowboy, and its people like him that give good honest tradesmen a bad name.
I would ask for the money back, ( I expect she paid more for a bodge job than what a good tiler on this site would charge)
It wont be long before those tiles are falling of, he should have stripped the old ones of first, cleaned the walls, repair and plaster damage before tiling using a good water proof tile adhesive.

Hi only for small patches!

Kind regards Mihail

Should never skim with 1 coat always done in two would call him back to come and do it properly

I would always 2 coat

I’d highly recommend not to use it, I used it once as a customer already bought it and I had to cover it with proper stuff

In my opinion no professional plasterer should ever consider using a one coat plaster. Thistle multi finish should be applied with two coats for the job to be completed correctly. Some may argue and say a one coat plaster is useful for a small patch job but I wouldn’t touch it personally..
