Hi
I've never used a spray machine and always plastered the conventional way.
However I have just lost out on a huge 7 bed house as some guy has come in and said to the client that the spray finish is far superior to troweling on. I have looked all over the Internet and it appears although the materials are a lot more the speed is phenomenal (upto five times faster) so not a lot of difference in total cost. What's bugging me is that I cannot find any written disadvantages to spraying (from a quality point) Can any of you chaps think of any disadvantages of spraying so I can arm myself with this in case i get stumped by a spraying plasterer again?
Thanks in advance
G
 
I wouldn't agree it been superior to put on than with a trowel faster yes but if your good with a trowel like we're expected to be then it's purely a labour saving thing.
 
Thanks smoother
Do you know if there is a difference in quality of material?
After scrolling through shed loads of info on the material I now understand spraying is big in Germany France etc.
I do a lot of work for a polish builder and he tells me that the plaster they use when spraying is not as durable as British gypsum and will mark easily if hit with anything. Have you had any experience with the spray products and if so is there any truth in this?
Cheers
 
Hi Garratt

Knauf specialise in Spray plaster in the UK - from MP75, MP Finish to the ready mixed range of spray plasters

Where are you based buddy? I can then tag the correct guy on here to get in touch with you to discuss further!

There is a machine section on the forum, you will find a fair few guys in there that spray plaster as well as render...

Good Luck in your research... There are horses for courses - and you will learn where and when spray is better!

Don't be afraid to ask questions and potentially ask to have a go or visit local sites where it is being done! Knauf will help with demos and trials, once we know what area you want to go into and what product to provide.

All the best

Thanks rich
I suppose if I could have a go at it I could then make my own mind up over quality, durability etc. I don't think spray plastering is something I really want to get into on the whole though as I generally do private work the odd new build etc (from my reading I understand the spraying is normally used in larger jobs commercial premises etc) having said that if there is someone from knauf willing to give me a free trial tuition or what have you it wouldn't hurt. I'm in the Cheltenham area.
Thanks

Clive Reeves (@Quinns) is your man!

His contact number is on the attached thread... I will get him on here - probably Monday.

Good Luck!

You may also want to get in touch with Ryan Plasterers One Stop Shop, he is based near you and does machines, Knauf products and demos!

Spraying on fast is one thing but can you trowel it up as fast? You can bring in more labour to follow the spraying but then more labour costs?

I like the airless spraying that curry is doing, that is more more manageable.
 
I'm not convinced spraying finish is any quicker or better than hand applied.hundreds of threads on here from years back.no doubt it's easier on the bones.
I would rather have a decent gang plod along using multi by hand than use a machine spraying airless which also needs sanding
 
I'm not convinced either but still feel the need to give it a blast and make my own mind up.
Trouble is if I could make it work for 3 sets a day, the sets would no doubt be bigger therefore more to trowel up which results in more damage to your body.

Ain't worth the hassle mate. As Bobby has said, increase your workload and take on a couple more lads to maximize your profits.

Hi Bobby (still needs sanding) what's that all about then? - just trying to arm myself with the disadvantages of spraying.

Airless needs a light sand afterward but @Curry is doing very well with it.... looks like Great system and i think they are now doing the decorating as well

Why would it need a light sand?
You don't need to light sand multi or board. I've seen some of the videos mentioned and speed etc if it's a case of needing a light sand I reckon I could keep up with these guys by doing a rolling set only trowling it twice and then give it a "light sand"
(Not trying to offend the spraying plasterers as I've not done it myself)
Is it that the spraying leaves ridges? Don't get enough time to trowel? Etc etc just trying to get my head round it all. Also if it needs a light sand is it a soft product like easifill?
Thanks

I dont know much about the plaster curry is using but I can imagine it is something like dry lining material. That needs a light sanding but a good product. Not brittle like conventional plaster.

For me his system takes the graft out of troweling up. It is that graft that wears your joints out and makes life miserable in later years. Something that younger spreads have yet to experience but they will and then wish they made life easier for themselves in their everlasting youth.

It looks like a good product.it seems like you will need a lot of m2 per week to keep busy though.curry seems to of got a decent system
mind.
Skimming a only hard work if the prices are poor so chasing the dollar all day.i get decent prices so no need to run around all day breaking the body.

Danny Immingham is far too far for you and me you know Kent makes sense. How about get them to come to mk and when they are here they can explain why a city like mk don't have any mp!
 
The thought of Kent gives me a nose bleed it was horrific when I had to go to 1stopshop it took 45 mins can you believe that ffs.
 
There are two forms of spray plastering.

1 spraying gypsum based products like mp finish or thistle spray. These are spray applied via a ritmo or other screw pumps

2 ready mix finishing plasters these are applied via both airless piston pump or screw pumps

Spraying gypsum is a ball ache compared to readymix so we dont do it anymore but it still quicker and easier then hand appling it. Quality is the same not better all it does it mix it and put it on the wall.

Ready mix is a different story. Its not only quicker but it higher quality. The product is superior in that it harder and more flexable. This material can be troweled to a finish in two passes. Its also less messy, requires hardly any water on site and metrial is packaged in plastic sacks so cant get ****** on site by the rain.

The only down side of both systems is that people struggle to get their heads around the fact that your gonna actually do 1000m2 in a week
