The walls are french white stuff, Looking to remove the current wallpaper and then fill and smooth. The walls are very crumbly and produce lots of thin powder and chunks. So looking for something to attach to the henry and suck all the bad stuff away. Will definitely get a paper tiger and some of the fluid.
Thanks for the gardz heads up. Do you paint it on once the walls are smothed and the 3 days passed to then aint on the walls?
The rooms are still going to require prep, one room being painted is the kitchen so sugarsoap to remove all the grease then the mask the edges and polythene on the floor. Then paint. Suspect my love of the paint pad might make it easier.

Good luck with that, unless you want to preserve the existing walls it sounds like a case for skimming or completely re-plastering. You can paint the Gardz on before filling and after. Full instructions are on the tin. Cases like this you have to assess as you go along unless you just decide to hack it all out and start again. I usually end up lining walls like this after filling them as the substrate is so difficult to repair and likes to crack up quite quickly after painting.

The only one I've used is my own Festool one which is a 225mm head and comes with a specific hoover designed to deal with plaster/filler dust. It's not that easy to use, pretty heavy on a long handle and you need to be careful with it. If you are using easy fill you can wipe the surface with a sponge and it will come up very flat, I know it doesn't seem like good advice but just try it and avoid years of sanding.
The other worthwhile product you might want to deal with your newly filled walls is Gardz. Well worth it for walls with patches of filler on, only problem is its only available in large quantities.
Paint spraying is all about masking and dealing with overspray, you spend a lot more time prepping and taping the skirting etc. Then you either have decent extraction for the overspray or risk covering everything with fine dust. It also takes time to clean the paint from the sprayer once you've used it and failure to do that will ruin the spray equipment. That process requires a fair bit of water too. If you are prepared to prep everything (all the rooms) that you want to paint then do them all at once with extraction you might be happier than using a roller but a 12 or 18 inch roller does the job so quickly that you may as well invest in a wide roller bucket, 18" roller and Wooster roller pole.
Spraying is generally worthwhile on surfaces like doors that you want a flawless finish and where they can be painted in a specific area which is set up to deal with overspray.
The Painters Pit Stop forum has a lot of threads concerning spraying.
