I would have loved to have changed from garbage BG to Knauf airless, but having read the technical sheet it looks like you tape and joint... wait 24 hours... then spray your room out, and wait 24 hours before spraying your second coat!
I can't price Joe Bloggs dining room to take 3 days!!
What's the deal?
 
I doubt it's geared to one of two rooms @CeeVee. When you've got a whole house to do or if new build move in this direction it will be a winner.

It's never going to take off with volume housebuilders.
There's not a penny pinching QS in the land who'd think jointing a house then spraying a finish on it (effectively doing the
Job twice) is a viable system.
Unless it's cheaper then just skimming which it's not, it's doomed.

I disagree Scottie. When Breeam and Leed get involved there are incentives given to move to greener and innovative procedures. Time will tell I suppose.

You don't tape and joint to the same level. Tapered edge scrim and joint filler and internal corners / but joints are either paper taped or fibafuse.

Then two coats of airless finish

It is quicker has a better finish and it's don't cost the contractor any more

If it's a reskim it can be done in 2 days

Airless works on reskims however it really works on new build and you can do it all in day. Tape with fast set then two coats.

Airless plastering is just a different option, some jobs are suitable some are not. It's funny how people are so resistant. It's like a plasterer refusing to learn rendering or screening. It's just a new skill set to learn and make money out off.

Hell of a lot easier in the body then skimming
 
How can it be quicker than skimming if you need to wait on it drying out before topping and then sanding?

There's no resistance from me I would welcome a new alternative to Gypsum, but this isn't it.

Nah I employ them to do the taping ahead of us. Then it's only 2 coats of airless for me :)

Steve are you making more or less money doing this or is just easier, you look like you've put on a bit of weight so it must be a lot less work.

You don't need to wait a day for the second coat. Yes it needs sanding a little but we also take on the decs and a good dec will always prep the plaster work prior to painting. So I takes no longer.

On larger contracts it's definatley quicker

It's easier and now do all the finishing we definitely turn a better profit.

Saying that I'm spraying monoblanco through the Ritmo at the moment. Both airless and skimming can't touch the profit ratio on new build rendering.

When spraying the paint on the walls what do you do to stop paint getting on the ceiling

Have a look on youtube for american decorators painting exteriors and interiors with airless I'm sure they use something like an artists palete to mask as they spray.

We started using it last autumn, the way i consider it viable for a job is if there would be at least four days worth of traditional plastering then the airless becomes an option.
day 1 prep
day 2 1st coat
day 3 2nd coat
day 4 sanding

It's not going to replace multi, but on the right jobs it's a better option.
Less mess, better finish, and far easier on the body. It feels like we're cheating

Must admit as a plasterer i hate the taping part

How long do you spend sanding
 
Not long really, depends how neat we are. we use a flex sander for most then a hand sander round internals.

To be honest we are still trying different ways, could use a chat with currier to pick his brains.

Also no need for a labourer at all, we usually spray with two of us but if i wanted to (and i have) you can spray and trowel on your own with ease, any size ceiling or whatever.

We've sprayed over board, painted walls, hardwall and bonding (both dried out)

Over the hardwall and bonding did u just use the airless finish or did you have to use airless backing. And did you devil float the hardwall

Where you from? Are you in Kent?

Good to see someone else that can see the benefits on the right job. It's also funny how now we only do the " right" jobs. f**k skimming everytime I have to do it I dislike it

I've got a house to float and set in a few weeks. Using mp75 and airless finish. I'll do some vids of both the Ritmo and airless machines in action.

You can coat mp75 the next day before it gets it sweat on. But it's much nice to wait till its dry
 
I work alone and use Knauf airless a lot. Most hallways I will now use Knauf backing and finish. No pressure now with the big walls spray halfway, move the ladders scaffold planks etc have a cup of tea an then carry on down the wall. My body certainly feels a lot better after a shift spraying.

I never going to be convinced a product that needs sanding is better than a skim finish
It's just a posh version of tape & jointing
